The network wiring must be complete before the nanoBTS can be installed and commissioned. The nanoBTS should be placed on a wall at or above head height or on a ceiling. Unless explicitly stated otherwise, the following procedure is common for both 139/140 and 165 hardware variants. Remove the nanoBTS from the bracket by sliding the removal tool over the central fin between the bracket and the body of the unit to disengage the locking spring, slide bracket to separate it from the main body of the unit. The tool may be inserted from the top or bottom of the nanoBTS Figure 12 - nanoBTS Bracket Removal Position the bracket on the wall and mark the position of the four screw holes. The top of the bracket MUST be positioned uppermost. Ensure that the bracket is level and sufficient clearance is maintained to allow the unit to be located on the bracket (at least 80mm from the bracket to the top of wall and 120mm from the side of the bracket to a side wall). See the diagram below, Figure 13 - Fixing the wall bracket. 80mm min120mm min Figure 13 - Fixing the wall bracket Drill the four holes in the positions marked previously and insert wall plugs (if required) and fix the mounting bracket securely to the wall. The bracket is designed to allow the nanoBTS unit to be mounted with the connections at the bottom of the unit. Slide the nanoBTS onto the bracket and ensure that the retaining spring engages into the indent at the rear of the unit.

Using BTS Installer, the user is able to configure (and reconfigure) nanoBTS™ installation parameters, download new software to nanoBTSs and perform Network Listen tests. This document covers only those aspects of nanoBTS installation that involve using BTS Installer. For full details of how to install a nanoBTS, please refer to [CENG0336]. 6.1.2 Related Documents [CENG0336] CENG0336, “nanoBTS Installation and Test Manual”, ip.access (latest issue) 6.2 Capabilities BTS Installer contains a collection of related tools that enable you to: • Perform initial installation and manual configuration of nanoBTSs. • Upgrade and reconfigure nanoBTSs. • Perform Network Listen tests. These include all the operations necessary to install and configure a nanoBTS to the stage where it will connect correctly to a BSC, from which point its telecommunications behaviour can be configured using management software. Before a nanoBTS can connect to a BSC: • It must have an IP address, and other IP configuration parameters must be set. • It must have a Unit ID, as this is what it uses to identify itself to the BSC. • It must have various non-volatile attributes configured; as a minimum it must know where to find the BSC before it can connect to it. At various times, either during initial installation of a nanoBTS or after it has already been operational for a while, it may be necessary to: • Change the nanoBTS’ IP configuration, Unit ID or non-volatile attributes. • Download a new version of software to the nanoBTS. • Perform various diagnostic operations on the nanoBTS, such as querying its current configuration. A nanoBTS can optionally communicate with the BSC via a secure SSL link. To configure it to do so it is necessary to: • Download a certificate to the nanoBTS

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 41 - • Download certificate revocation lists to the nanoBTS from time to time BTS Installer contains tools to carry out all these actions. It can do so • To one nanoBTS at a time or several nanoBTSs at once. • Automatically or manually. • According to information either loaded from a configuration file or entered via the graphical user interface. To allocate IP addresses and other IP configuration to nanoBTSs, BTS Installer contains a built-in DHCP server. This will respond to requests from nanoBTSs only, so should co-exist with any other DHCP servers that are present on the same network. In addition BTS Installer contains a Network Listen tool that enables you to control a nanoBTS to: • Listen to its GSM band and report on received signal strength and BCCH details for each ARFCN. • Correct its clock by reference to the signals from other cells. • Transmit a beacon signal that can be listened to and measured by other nanoBTSs, which can be useful in ensuring adequate coverage of an area.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 42 - 6.3 Concepts This section describes some basic concepts behind the operation of BTS Installer; without an understanding of these it will be difficult to make sense of instructions for using the tool. Figure 24 is an illustration of BTS Installer’s user interface, and this is referred to when explaining some of these concepts. Detailed explanations of all aspects of the user interface will be found in later sections. Figure 24 - Main Display

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 43 - 6.3.1 The BTS Database BTS Installer will only operate on a nanoBTS that it knows about. The collection of nanoBTSs that BTS Installer knows about is called the BTS Database. The BTS Status section at the bottom of the graphical user interface is a display of the current status of each entry in the BTS Database – each row in this table represents one nanoBTS that BTS Installer knows about. There are several ways in which BTS Installer can get to know about a nanoBTS, ie ways in which a nanoBTS can be added to the BTS Database: • Information about the nanoBTS can be loaded from a configuration file (see section 6.3.4). • The Find command will create BTS Database entries for one or more nanoBTSs that BTS Installer was able to locate on the local LAN (these nanoBTSs must already have valid IP configurations for the Find command to work). • The New command will create a BTS Database entry full of default values; the user must edit some values in this entry before it is useful, and in particular must enter either a MAC address or an IP address or a Unit ID before BTS Installer will be able to identify the nanoBTS to which the entry relates. • The IP address and optionally the Unit ID of the nanoBTS can be specified on the command line when BTS Installer is started. BTS Database entries are deleted: • When the Delete command is used. • When a new configuration file is loaded. • When BTS Installer is shut down. A BTS Database entry can be edited: • Using the Edit command. • Indirectly using the Defaults command, which affects all BTS Database entries that don’t have more specific values. None of BTS Installer’s tools, including the DHCP server, will operate on a nanoBTS for which there is no BTS Database entry.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 44 - 6.3.2 Configuration Phases Configuration of a nanoBTS takes place in a number of phases. In automatic mode (see section 6.3.3.1) all enabled phases are run automatically one after another in a fixed order; in manual mode the user chooses which phase to run, one at a time, and can also perform other actions which are not equivalent to automatic configuration phases. The configuration phases are, in the order in which they are run in automatic mode: • Setting the nanoBTS’ IP configuration using the built-in DHCP server. • Setting the nanoBTS’ Unit ID. • Setting the nanoBTS’ non-volatile attributes. • Downloading a file to the nanoBTS. Each phase can be enabled or disabled separately for each nanoBTS. The download file can download any one of: software; a certificate; a certificate revocation list, but can only download one file at a time. The BTS Status section of the user interface gives a quick reference to which phases are enabled for which nanoBTSs: this is indicated by the colour code in the columns headed respectively DHCP, UNIT Id, NV Attr, D’LOAD – grey indicates that this phase is disabled for this nanoBTS, any other colour indicates that this phase is enabled for this nanoBTS. Status colours other than grey are accompanied either by explanatory text, or by a symbol (Grey = no symbol, Red = cross, Yellow = question mark, Red = tick). 6.3.3 Modes of Operation BTS Installer has a variety of different modes of operation, to suit different circumstances and requirements. 6.3.3.1 Manual and Automatic Operation BTS Installer has an automatic mode of operation, in which it will apply all enabled phases of configuration to all known nanoBTSs in parallel, and when it has finished it will produce a summary in the log window and log file and will display in the BTS Status window which phases of configuration for which nanoBTSs have succeeded and which have failed. This automatic mode of operation is initiated by pressing the Auto button in the BTS Database Log section of the user interface. BTS Installer also has a manual mode of operation, in which the user performs just one operation at a time on just one nanoBTS at a time, and has immediate feedback as to the success or failure of the operation. The various manual operations are available from pressing the Action button in the BTS Status section of the user interface. Some example scenarios are: • A number of operating nanoBTSs are to have their software upgraded. Automatic mode is used to download the new version of software to all of them at once.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 45 - • A particular nanoBTS is not operating correctly. Manual mode is used to investigate its configuration and diagnose and fix the problem. 6.3.3.2 The Unknown BTS Mode Normally the BTS Database contains entries for specific nanoBTSs. In particular the DHCP server will only normally only supply an IP configuration to a nanoBTS whose MAC address matches that explicitly specified in the BTS Database entry. There is a special “Unknown BTS” mode of operation in which the BTS Database contains just one special entry. This special entry acts as if it had a wildcard MAC address, and the DHCP server will recognise any nanoBTS that asks for an IP configuration. IN THIS MODE THERE IS NOTHING IN BTS Installer TO STOP THE CONFIGURATION OF ANY nanoBTS THAT IS CONNECTED TO THE NETWORK FROM BEING CHANGED. This special mode of operation is designed to be used when only one nanoBTS at a time is connected to the computer running BTS Installer, usually on a tiny private network, perhaps just a crossover cable. It bypasses the normal safeguards that BTS Installer uses to ensure that it makes configuration changes only to BTSs that are identified as those that the user has specified. There is no way to create this special BTS Database entry from the graphical user interface; it must be loaded from a configuration file. There is no particular indication to the user that BTS Installer is in Unknown BTS Mode, except that the Find and New buttons in the BTS Status section of the user interface are disabled. 6.3.3.3 Proxy and Direct Operation There are various network configurations in which BTS Installer may be used, and the general design of the IP network configuration is outside the scope of this document. In some network configurations BTS Installer is on the same network as the nanoBTSs, in that there is an IP route from BTS Installer to the nanoBTSs. In such configurations BTS Installer can communicate directly with the nanoBTSs in direct connection mode. There are two different types of direct connection that BTS Installer can make to a nanoBTS: a normal TCP connection or a secure SSL connection. In other network configurations BTS Installer and the nanoBTSs are on different networks, and there is no IP routing between the two. Typically in this scenario the BSC will be multihomed, and will have an interface to each network but will not route IP packets between the two networks. An optional system component, the BTS Installer Proxy, can be installed as part of the BSC, and will forward requests from BTS Installer to the nanoBTSs and return the replies. In such configurations BTS Installer communicates with the nanoBTSs in proxy mode. There are two different types of proxy that might be present on a BSC: a Primary OML Proxy and a Secondary OML Proxy. Which can be used depends on the network configuration.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 46 - Direct connection or proxy mode is indicated to the user in the status bar at the bottom of the user interface. A later section explains how to start BTS Installer in proxy mode, and lists the limitations of BTS Installer whilst in proxy mode. 6.3.4 The Configuration File BTS Installer can be given the information it needs • in a configuration file, or • via the graphical user interface, or • via some combination of both. The configuration file is a text file which can be created with any text editor and which contains definitions for: • default values for BTS attributes • the nanoBTSs to be operated on • attributes to be set for the BTSs • the DHCP server’s IP address pool. It is not necessary to create a configuration file for most uses of BTS Installer, as almost all necessary information can be entered via the graphical user interface. The only exception is that a BTS Database entry for the “Unknown BTS” cannot be entered via the GUI and can only be entered via the configuration file. At any point it is possible to save the current state of the BTS Database and IP address pool to a configuration file; this can be done even if no configuration file has been loaded and all data has been entered via the GUI. This allows you to • enter configuration information via the GUI • save this to a new configuration file • load the configuration file in a later run of BTS Installer. In other words, you can use BTS Installer itself to create a configuration file for later use, instead of using a text editor. Section 6.10 gives details of the syntax of the configuration file.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 47 - 6.4 Getting Started This section contains information about installing BTS Installer, preparing it for use, and performing an operation on a nanoBTS. 6.4.1 Installing BTS Installer BTS Installer is a Java application. It requires that the Sun J2SE Java Runtime Environment be installed: version is 1.5 is required (there is no particular requirement as to which subversion of 1.5 is used). The J2SE Java Runtime Environment is available, with installation instructions, from Sun’s Java web-site (http://www.java.sun.com). 6.4.1.1 Microsoft Windows To install BTS Installer run the supplied .msi file and follow the instructions on screen. If it is desired to use BTS Installer to make secure (SSL) connections to nanoBTSs then • the Aladdin eToken run time environment must be installed, which in turn requires that the computer is running either Windows 2000 SP4 or Windows XP or later • the eToken, which is a hardware device which contains a certificate and private key for BTS Installer, must be plugged into a USB port. 6.4.1.2 Other Platforms Details of installing BTS Installer on platforms other than Microsoft Windows are beyond the scope of this document. However in most cases copying the file BtsInstaller.jar to a suitable directory will be adequate. On platforms other than Windows there is no support for making SSL connections to the nanoBTS. 6.4.2 Starting BTS Installer 6.4.2.1 From Config Manager BTS Installer can be started from Config Manager, in which case it will be pre-populated with some nanoBTSs selected in Config Manager and will operate in proxy mode. See section 6.9.2 for details. 6.4.2.2 Microsoft Windows BTS Installer can be started by double clicking the desktop item or by selecting the menu entry in the normal way. 6.4.2.3 Other Platforms Details of starting BTS Installer on platforms other than Microsoft Windows are beyond the scope of this document. However on platforms with a command line interface a command like: java -jar BtsInstaller.jar is likely to be useful.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 48 - 6.4.2.4 Command Line Arguments On all platforms, additional command line arguments can be used to specify that BTS Installer should run in proxy mode, and/or to specify the IP addresses and optionally Unit IDs of some nanoBTSs for which BTS Installer should create BTS Database entries. See section 6.9.3 for details of these command line arguments. At the end of the command line the following arguments may be present: /AUTO filename If these are present BTS Installer will (a) load the specified file as a configuration file (b) perform an automatic run (c) shut itself down thus providing an unattended mode in which BTS Installer may be run entirely from the command line. Depending on the platform, it will be possible to set up a shortcut or a script to run BTS Installer with any desired set of command line arguments. 6.4.3 Entering the password When BTS Installer starts, if an eToken containing a certificate and private key is found it will prompt the user for the password for the eToken. The password should be entered if it is desired to make secure (SSL) connections to nanoBTSs; if only insecure connections are wanted then the password request may be cancelled. See section 6.10 for further details. 6.4.4 Setting Up BTS Installer The BTS Installer Configuration section of the user interface (Figure 25) contains some settings that tell BTS Installer how it is to operate. Until some of these settings have been made most of the buttons on the user interface will be disabled and most of BTS Installer’s functionality will be unavailable. Once these settings have been made they are remembered and will not normally need to be made again on later runs of BTS Installer on the same computer. The items that can be set up are: • Log file directory – see section 6.5.1.1 – this must be set up, but it can alternatively be done as a by-product of choosing a configuration file (see section 6.5.1.3) • IP Address – see section 6.5.1.2 – this does not need setting if you are not going to use BTS Installer’s built-in DHCP server, but if you are going to use the DHCP server then this must be set up

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 49 - • Configuration file – see section 6.5.1.3 – this need not be set up unless and until you wish to use a configuration file • Options – see section 6.5.1.4 – these usually do not need to be set up as the default values are usually adequate. 6.4.5 Creating a BTS Database Entry BTS Installer will not operate on any nanoBTS that it doesn’t know about; in order to do anything to a nanoBTS it must have a BTS Database entry for that nanoBTS (see section 6.3.1 and section 6.5.4.2). A BTS Database entry can be created by any of the following methods as desired: • create a new blank BTS Database entry – see section 6.5.4.2.2 • finding a nanoBTS on the local area network – see section 6.5.4.2.1 • load a configuration file – see section 6.5.1.3 6.4.6 Assigning an IP address For most operations (other than when operating via a Primary OML Proxy) the nanoBTS must have an IP address assigned, and BTS Installer must know the IP address. If the nanoBTS on which you wish to operate already has an IP address: • ensure that the BTS Database entry for that nanoBTS has the correct IP address; if not use the Edit button to fill in the IP address on the BTS tab of the BTS Configuration dialog box. If the nanoBTS on which you wish to operate does not already have an IP address then you may use BTS Installer’s built-in DHCP server to assign one: • consult the network administrator for the network on which the nanoBTS is installed and ask for an IP address that can be used for the nanoBTS • use the Edit button to fill in this IP address on the BTS tab of the BTS Configuration dialog box • go to the DHCP tab on the same dialog box, (and if not already done) tick the Enable DHCP Configuration check box, and enter the correct Subnet Mask (and Router address, if needed) • ensure that the DHCP server is running • wait until the DHCP server assigns the address to the nanoBTS. For more information about editing the nanoBTS’ attributes using the BTS Configuration dialog box see section 6.7. For more information about the DHCP server, particularly for conditions that must be satisfied before it will work and assign an IP address to a nanoBTS, see section 6.6. 6.4.7 Setting desired nanoBTS attributes For many, but not all, operations it is necessary to specify some attributes that you wish to be configured on the nanoBTS.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 50 - Use the Edit button to pop up the BTS Configuration dialog box on which desired attributes may be entered. See section 6.7 for complete details of the BTS Configuration dialog box. 6.4.8 Perform desired operations At this point any desired operation may be performed on the nanoBTS: • automatic configuration – use the Auto button • manual configuration – use the Action button • network listen functions – use the Listen button. Section 6.5 is a reference for the user interface and gives details of all these operations.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 51 - 6.5 User Interface Reference BTS Installer’s user interface is divided into four areas, as shown in Figure 24. Each area is described in detail in this section. 6.5.1 BTS Installer Configuration section The first section of the user interface contains settings concerned with the operation of BTS Installer itself. The user must set up a Log File Directory – there are two ways of doing this, see section 6.5.1.1 or section 6.5.1.3. Until a Log File Directory has been specified most of BTS Installer’s buttons will be disabled and most functionality will be unavailable. If BTS Installer’s built-in DHCP server is to be used the user must set up BTS Installer’s IP address – see section 6.5.1.2. If this is not done the DHCP server will terminate with an error message. The Configuration File and Options may be configured as the user desires. Most of the settings in this section of the user interface are remembered for future runs of BTS Installer, so they don’t need to be entered each time BTS Installer is used. Figure 25 - BTS Installer Configuration section

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 52 - 6.5.1.1 Log file directory selection BTS Installer insists on logging everything interesting it does. So it won’t do anything much, and most functions will be disabled, until a log directory has been specified in which it can create log files. There are two ways to specify the log file directory: If a “Configuration File Name” is specified (it doesn’t have to be actually loaded) and the directory containing the configuration file also contains a subdirectory called “log” then this “log” directory will be used for log files (see section 6.5.1.3). The user can specify a log file directory explicitly, using the “Browse” button in the “Log File Directory section” section of BTS Installer’s main window (see Figure 26). Figure 26 - File Selections This will bring up the Log File Directory selection window as shown in Figure 27. Figure 27 - Setting Log File Directory Using the window shown above browse to the selected location for log files to be stored in and click on select. Once a log file directory has been specified it is stored persistently so is remembered next time BTS Installer is run.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 53 - 6.5.1.2 IP address selection Some operations of BTS Installer require it to know its own IP address and/or subnet mask. Where the application is running on a computer with more than one Ethernet adapter there is no way that the tool can know which of its multiple IP addresses it should be using. To tell BTS Installer which IP address and subnet mask it should be using, use the “Configure” button in the “BTS Installer Configuration” panel (see Figure 28). Figure 28 - Configure BTS Installer IP Address This should pop up a dialog box containing a list of the network adapters found: Figure 29 - Selecting BTS Installer IP Address Expand these nodes as necessary to find the IP address you want to use and then select it, causing it to be copied to the “DHCP Server IP Address” field. The “Listen Only On This Address” option, if selected, will cause both the DHCP server and the Find feature to ignore incoming messages on other network adapters; this is only an issue if the machine running BTS Installer has multiple network adapters and there are BTSs on more than one subnet which are known to BTS Installer – in most circumstances this option can be left unchecked. If the “Listen Only On This Address” option is selected then BTS Installer needs to know its subnet mask: check the “subnet mask” field; this is not necessarily the correct subnet mask for the selected interface, as the BTS Installer application is written in Java and there is no portable way to obtain this information – the suggested value in this field is calculated from the class of the IP address, and this may or may not be correct for the particular network in use.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 54 - These options are stored persistently so are remembered next time BTS Installer is run. Whenever these options are changed the DHCP server will need to be stopped and restarted in order to notice the new values. 6.5.1.3 Configuration file Once the IP address has been selected and the log file directory has been specified most functions of BTS Installer are available and can be used without loading a “configuration file”. The configuration file can be used to automatically configure 1 or more nanoBTS from a preset configuration. This can be particularly useful when deploying a number of nanoBTS at the same time such as may happen during an office application deployment. To use a configuration file BTS Installer must first know where to find the configuration file. The user can specify a configuration file in the “Configuration File” section of BTS Installer’s main window; either by entering the full pathname of the file in the text box or by using the “Browse” button which pops up a standard file selection dialog box.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 55 - 6.5.1.4 Options The user selects the Bts Installer Options using the Configure button in the Options panel. This should pop-up an Options dialog box that gives access to a number of settings. The Options dialog box (Figure 30) allows the user to change the default timers, the reconnection attempts and also the window size used during software download. The default values are chosen so as to work with current versions of nanoBTS software under normal local area network conditions whilst minimising waits and delays. Under some circumstances some operations might result in error messages, usually about things timing out, in which case you may wish to change some of the default values. Figure 30 - Options dialog box Here are some example circumstances in which you may wish to try values other than the defaults: • If the download is found to be unreliable due to poor network performance then it is likely to be helpful to change some of these settings. For example, if problems are encountered when trying to download software to many nanoBTSs at once via a BTS Installer Proxy you might try increasing the GSM 12.21 procedures timeout, say to 30 seconds, and reducing the Software Download Window, say to 5. • The Software Activation timeout is reasonable for current versions of nanoBTS software. If later versions of nanoBTS software need longer to complete software activation this timeout will need to be increased, otherwise Network Listen tests will not be possible. • The Allowance for Shutdown timeout is reasonable for current versions of nanoBTS software. If later versions of nanoBTS software need longer to complete shutting down this timeout will need to be increased; conversely if

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 56 - later versions of nanoBTS software shut down more quickly then this delay could be reduced to speed up operation. • After performing an operation in which BTS Installer resets the nanoBTS and then has to reconnect to it, it attempts reconnection the number of times specified by Reconnect retries, and gives up on each connection attempt after the time specified by Connecting to the BTS. These numbers are reasonable for current versions of nanoBTS software, but if later versions take longer to restart after being reset then one or both of these numbers may need to be increased. For an explanation of the SSL options see section 6.10. 6.5.2 DHCP Server section This section of the user interface, shown in Figure 31, allows you to control BTS Installer’s built-in DHCP server, and contains a scrolling log of DHCP server activity. For a more detailed description of what the DHCP server is, how it works, and how to use it, see section 6.6. The DHCP server provides IP address information and some basic configuration information to the nanoBTS. Figure 31 - DHCP Window 6.5.2.1 Starting and stopping The DHCP server can be started with the Start button and stopped with the Stop button. When BTS Installer is started in direct connection mode the DHCP server is running by default; when BTS Installer is started in proxy mode the DHCP server is stopped by default. 6.5.2.2 The IP address pool The DHCP server can have a pool of IP addresses that it will hand out to nanoBTSs that request IP addresses. See section 6.6.3 for information about how this works, when the IP address pool is used and whether you need to create an IP address pool. The Pool button will display the IP address pool as shown in Figure 32. There is a row for each IP address in the pool, with a colour code (and symbol) indicating the status of each address as follows: Colour Symbol Meaning Grey none This IP address is not in use, and is available for allocation

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 57 - Colour Symbol Meaning Yellow question mark This IP address has been offered to a nanoBTS which has not yet accepted or rejected it Green tick This IP address is allocated to a nanoBTS Red cross This IP address has been offered but the nanoBTS has rejected it Figure 32 - IP Address Pool Clicking on column headings will sort the display. The Add button allows one or more IP addresses to be added to the pool. The example in Figure 33 will add the addresses 192.168.0.200, 192.168.0.201, 192.168.0.202, 192.168.0.203, and 192.168.0.204. Figure 33 - Adding IP addresses to the pool To delete one or more addresses from the pool, select them in the table and press the Delete button. 6.5.2.3 DHCP server log The DHCP server’s log window shows an entry for every DHCP message that the server receives or sends, and an entry for each operation on the IP address pool. Figure 34 - DHCP server log

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 58 - The sequence of log entries shown in Figure 34 is a typical sequence showing the DHCP server receiving a request from a nanoBTS and allocating it an IP address from the IP address pool. You may see other “Received:” messages which are nothing to do with nanoBTSs: the DHCP server will not respond to these. If you see “Received:” messages which you believe are from nanoBTSs and to which you expect the DHCP server to reply, but you don’t see replies from the DHCP server, please review section 6.6.2 which explains the conditions under which the DHCP server will respond to requests. 6.5.3 BTS Database Log section This section of the user interface, shown in Figure 35, has two functions: • it contains a log of all BTS Installer’s activity • it allows starting and control of the automatic configuration mode. Figure 35 - BTS Database Log section 6.5.3.1 Log The log window displays a message for each action taken by the user or BTS Installer that could affect one of the nanoBTSs in the BTS Database (see section 6.3.1). As well as being displayed in the window, messages are written to a log file. The name of the current log file is displayed beneath the log messages; this file name is constructed from the name of the current configuration file, if any (see section 6.5.1.3), and a timestamp. The directory to which the log file is written is chosen by the user as described in section 6.5.1.1. 6.5.3.2 Automatic configuration Pressing the Auto button will start automatic configuration mode. BTS Installer will then run all enabled configuration phases (see section 6.3.2) for all nanoBTSs in the BTS Database (see section 6.3.1).

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 59 - During automatic configuration, messages will be written to the log window and the log file indicating each stage of processing for each nanoBTS. Any error messages relating to any configuration failures will also be logged. As automatic configuration proceeds the various colour codes shown in the BTS Status window will be updated. When configuration of all nanoBTSs is complete a summary will be written to the log window and log file listing all the nanoBTSs and saying whether configuration succeeded or failed for each one. During automatic configuration the Auto button will be disabled and the Cancel button will be enabled. Pressing the Cancel button will abandon automatic configuration; as for normal completion of automatic configuration a summary is written to the log, and each nanoBTS whose configuration did not complete is listed as having failed. 6.5.4 BTS Status section This section of the user interface, shown in Figure 36, has the following functions: • it displays the current status of the contents of the BTS Database • it allows nanoBTSs to be added to the BTS Database – New and Find buttons • it allows nanoBTSs to be deleted from the BTS Database – Delete button • it allows editing of the parameters and attributes of the nanoBTS in the BTS Database – Edit and Default buttons • it gives access to the various manual configuration commands – Action button • it gives access to the Network Listen feature – Listen button Figure 36 - BTS Status section 6.5.4.1 BTS Database Display The main part of the display contains a table with a row for each nanoBTS known to BTS Installer, ie each nanoBTS in the BTS Database (see section 6.3.1). The table has 3 data columns and 4 status columns. The data columns show the MAC Address, IP Address, Unit ID and Location of the nanoBTS. The four status columns show the following information: DHCP What BTS Installer thinks about the current state of the DHCP configuration for this nanoBTS

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 60 - UNIT ID What BTS Installer thinks about the current state of the UNIT ID set for this nanoBTS NV Attr What BTS Installer thinks about the current state of the non-volatile attributes for this nanoBTS D’LOAD What BTS Installer thinks about the firmware currently loaded on this nanoBTS The coloured indicators have the following meanings: Colour Symbol Meaning Grey none The configuration phase is disabled for the nanoBTS, and BTS Installer is making no statement as to the status of this aspect of the nanoBTS’s configuration. Green tick The configuration phase is enabled for the nanoBTS and as far as BTS Installer knows, this aspect of the nanoBTS is configured as required. This usually indicates either that BTS Installer has configured it correctly, or that it has detected that the nanoBTS is already configured as required. Yellow question mark The configuration phase is enabled for the nanoBTS but BTS Installer doesn’t know whether this aspect of the nanoBTS is currently correctly configured. This is usually because BTS Installer has not read the current values from the nanoBTS and this configuration phase is enabled but has not yet been carried out. Red cross The configuration phase is enabled for the nanoBTS and as far as BTS Installer knows, this aspect of the nanoBTS is not configured as required. This usually indicates either that an error occurred when BTS Installer tried to apply the required values, or that BTS Installer knows that the user has entered new values and the configuration phase has not yet been run. In Figure 36 above, DHCP and D’LOAD are enabled for the first BTS, and DHCP succeeded, while the software download failed. Just DHCP is turned on for the other BTSs but has not yet been carried out. Similar coloured status indicators for nanoBTS configuration phases also appear elsewhere in the user interface, with the same meanings. Note that the red and green indicators can become out of date as a result of changes to the nanoBTS that are not made using BTS Installer. 6.5.4.2 Creating BTS Database entries There are three ways to make a nanoBTS known to BTS Installer, ie to create an entry in the BTS Database and add a line to the BTS Status display: • load a configuration file (see section 6.5.1.3) • Find one or more nanoBTSs • make a New BTS Database entry. 6.5.4.2.1 Finding nanoBTSs The Find button allows BTSs on the local network to be located and added to the BTS Database for later configuration.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 61 - Pressing the Find button causes BTS Installer to look for nanoBTSs on the local area network and display the results as shown in Figure 37. The display can be sorted on any column by clicking on the column heading. If BTS Installer is running on a computer that has more than one network adapter installed and enabled, Find will look for nanoBTSs on all of the connected local area networks unless the Listen Only on This Address option is ticked on the Configure BTS Installer dialog box (see section 6.4.6) in which case it will only look for nanoBTSs on the local area network connected to the adapter which has the specified IP address. Note that BTS Installer looks for nanoBTSs using UDP broadcasts. In typical network configurations this means that BTS Installer can only find nanoBTSs that are present on the same local area network. In particular if the network configuration is such that BTS Installer needs to run in proxy mode then it is unlikely that the Find command will locate the nanoBTSs, and they will need to be added to the BTS Database by one of the other means available. Figure 37 - “Find” Results Once the Find operation is complete it is possible to select either the nanoBTS that requires configuration alone or a number of nanoBTSs for multiple site configurations. Simply select a nanoBTS with the left mouse button (or a number of contiguous nanoBTSs by holding down the shift key + pressing left click on the mouse, or a number of non-contiguous nanoBTSs by ctrl + click) and then click Select. The Refresh button will repeat the search for nanoBTSs. If you have just powered up a nanoBTS you may have to repeat Refresh several times before the nanoBTS has booted up and reached the stage where it can be found and will appear in the list. Pressing the Cancel button removes the Select nanoBTS dialog box.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 62 - 6.5.4.2.2 Creating a New BTS Database entry The New button will create a new blank BTS Database entry. It will pop up a BTS Configuration dialog box to allow you to edit the attributes of the BTS. See section 6.7 for a complete reference to all the attributes. 6.5.4.3 Deleting BTS Database entries To delete one or more BTS Database entries, select them in the BTS Status window and press the Delete button. 6.5.4.4 Editing nanoBTS attributes To edit the attributes for a particular nanoBTS, select the relevant entry in the BTS Status window and press the Edit button. A BTS Configuration dialog box for this nanoBTS will appear. See section 6.7 for a complete reference for this dialog box. To edit default values that BTS Installer will use for all nanoBTSs that do not have explicit values specified press the Defaults button. A BTS Configuration dialog box for the default values will appear. See section 6.7 for a complete reference for this dialog box and a description of how the default system operates. 6.5.4.5 Manual configuration To perform various manual configuration operations on a nanoBTS, select the relevant entry in the BTS Status window and press the Action button. The Configure BTS dialog box will appear. See section 6.5.5 below for a full description of the various operations available from this dialog box. 6.5.4.6 Network Listen To perform various Network Listen tests on a nanoBTS, select the relevant entry in the BTS Status window and press the Listen button. The Network Listen window will appear. See section 6.8 for a full description of the Network Listen tests.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 63 - 6.5.5 Manual configuration operations The Configure BTS dialog box (see Figure 38) gives access to a number of manual BTS configuration operations. Figure 38 - Configure BTS dialog box The status displays show the same information as in the relevant row in the BTS Status window, with the addition of the filename of any software configured for downloading. The Edit button is an alternative means of opening the BTS Configuration dialog box to edit this nanoBTS’ attributes. The buttons down the right hand side give access to the various manual configuration options. The Close button removes the Configure BTS dialog box. 6.5.5.1 The Progress Dialog box Most of the manual operations involve BTS Installer establishing a connection with the nanoBTS, and then carrying out a transaction involving a number of messages backwards and forwards. During such processes a progress dialog box is displayed as shown in Figure 39. Figure 39 - Progress Dialog box The progress dialog box indicates how the operation is progressing, and how it finished. On successful completion it will usually display something like “Get Attributes complete”, except where the operation involves resetting the nanoBTS in which case the final message on success will be “Reinitialise requested” at which point the nanoBTS shuts down and restarts.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 64 - If the operation fails then an error message will be displayed in the progress dialog box and you will need to use this message to diagnose and correct the problem. The Cancel button on a progress dialog box can be used at any time to abandon the operation. This changes to a Close button when the operation has completed, whether successfully or not. An open or closed padlock is displayed to indicate whether the connection is insecure or secure (SSL) – see section 6.10 for more information about SSL connections to nanoBTSs. 6.5.5.2 SW Activate For some diagnostic engineering procedures outside the scope of this User Guide it may be necessary to activate the software in the nanoBTS. If so then press the SW Activate button. The only function of BTS Installer that requires Software Activation is the Network Listen feature, and this does its own software activation automatically. In normal use of BTS Installer there will never be any requirement to use the SW Activate button. This function does not work if the connection to the nanoBTS is via a Primary OML Proxy. See section 6.9 for more information. 6.5.5.3 Configure Unit ID The Configure Unit ID button is used to change the nanoBTS’ Unit ID, which is what the nanoBTS uses to identify itself to the BSC and to the user via management software. This button is only enabled if the Unit ID configuration phase is enabled. See section 6.7.8 for details of how to enable the Unit ID configuration phase and how to specify the nanoBTS’ Unit ID. When the Configure Unit ID button is pressed the Unit ID specified on the Unit ID tab of the BTS Configuration dialog box is sent to the nanoBTS, which is then optionally reset. A progress dialog box (see section 6.5.5.1) is displayed during this process and will indicate whether the operation succeeded.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 65 - 6.5.5.4 Set/Get NV Attributes The Set/Get NV Attributes button is used to perform some or all of • Set new values for some or all non-volatile attributes in the nanoBTS • Fetch some or all of the values of non-volatile attributes from the nanoBTS • Fetch some or all of the current values of attributes from the nanoBTS The “NV” value of an attribute can differ from the “current” value of an attribute in some cases because some changes to some non-volatile attributes do not take effect immediately. Some, for example, only take effect the next time the nanoBTS is restarted; in such cases the values fetched for “NV Attributes” will be those that are stored in non-volatile memory and that will be used next time the nanoBTS is restarted, and the values fetched for “Current Attributes” are the values that the nanoBTS is using at the moment. Figure 40 - Set and/or Get NV Attributes dialog box The Set/Get NV Attributes button will produce the dialog box show in Figure 40. This allows the user to choose which attributes are set, then which have their NV values fetched and which have their current values fetched. The initial state of this dialog box is BTS Installer’s best guess as to what the user is likely to want. Note that there are some NV attributes that cannot be set in this way, although their values can be fetched. These are: • Frequency Control – use the Frequency Control command instead. • IP Interface Configuration and IP Gateway Configuration – use the Change IP Configuration command instead. • Unit ID – use the Configure Unit ID command instead.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 66 - In addition there are some NV attributes that cannot be fetched in this way either. These are: • Current SW Configuration – use the Set Current SW and Fetch HW & SW Configuration commands to examine and change the current software configuration. When the Set/Get NV Attributes command has completed the BTS Configuration dialog box is displayed showing any values fetched. See section 6.7 for a full description of that dialog box. 6.5.5.5 Download Software The Download Software button is enabled only if the software download configuration phase is enabled. It will cause new software to be downloaded to the nanoBTS as specified in the Download tab of the BTS Configuration dialog box (see section 6.7.13). Use the Edit button to open the BTS Configuration dialog box if necessary. Note that this button always attempts to download new software, regardless of the type of download (software, certificate or CRL) that is selected on the Download tab of the BTS Configuration dialog box. To download a certificate or certificate revocation list to the nanoBTS use the Security… button rather than the Download Software button.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 67 - 6.5.5.6 Set Current SW The Set Current SW button fetches information about the current software configuration from the nanoBTS, and allows the user to change the software configuration, ie specify which software will run next time the nanoBTS is restarted. There is also an option to restart the nanoBTS. First this command fetches the current software configuration and displays it in the dialog box show in Figure 41. Figure 41 - Current SW Configuration dialog box There will always be one version of Boot Code software displayed; there will be up to two versions of each of Backhaul software and TRX software, depending on what has been downloaded to the nanoBTS. The current software versions will be selected; these are the versions that will be run the next time the nanoBTS is restarted, and may not be the versions that are currently running in the nanoBTS. If you select a different version of software using the radio buttons, the OK button will be enabled, as will the Reinitialize check box, allowing you to specify that a different versions of software be loaded next time the nanoBTS restarts, and also allowing you to restart the nanoBTS immediately to use these different versions. 6.5.5.7 Reset BTS The Reset BTS button instructs the nanoBTS to reset itself. After using this command you will be unable to contact the nanoBTS using BTS Installer for a while.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 68 - 6.5.5.8 Fetch HW & SW Configuration The Fetch HW & SW Configuration button fetches • software configuration information • hardware configuration information • in service time, the cumulative number of hours for which the nanoBTS has operated • up time, the number of hours, minutes and seconds the unit has been operating since the nanoBTS was last (re-)started1 and displays them in a dialog box as show in Figure 42. Figure 42 - HW & SW Configuration Dialog box 1 The Up Time attribute is only supported from System Release 2.0 onwards. For nanoBTSs running software from releases prior to SR2.0, the Up Time field will be blank

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 69 - 6.5.5.9 Change IP Configuration The Change IP Configuration button pops up the dialog box shown in Figure 43 which displays the nanoBTS’ current IP address and allows the user to change the IP address, subnet mask and default gateway. Figure 43 - Change IP Configuration dialog box The nanoBTS may be optionally restarted after setting these attributes; the nanoBTS will not use the new values of these attributes until it is restarted, and if you don’t restart it at this stage BTS Installer will probably try to contact it in future using the new IP address and will probably fail. This is one of two methods of changing the IP configuration provided by BTS Installer, and is the method to use if you are not using BTS Installer’s built-in DHCP server to provide this information to the nanoBTS. NOTE: User has to enter values for all the three new parameters (i.e. New IP Address, New Subnet Mask and New Default Gateway). If any one value missed to enter then default value (0.0.0.0) will be configured which may lead incorrect IP configuration to BTS. 6.5.5.10 Frequency Control [See the ip.access document, “nanoBTS Synchronisation Feature Definition”, for a description of how the GSM frequency accuracy requirements are met in the nanoGSM™ system.] The Frequency Control button allows the user to make manual adjustments to the nanoBTS’ clock frequency, via the Frequency Control attribute, which is represented as a number of ppb (parts per billion) from a nominal value. 2,3 It also allows the user to view the Timing Bus status, which is of interest in the case of multi-TRX capable nanoBTSs.4 2 It is generally easier to adjust a nanoBTS’s clock frequency using the Network Listen Frequency Synchronisation Test (see section 6.8.7) or - for multi-TRX capable nanoBTS models - an accurate 10 MHz clock source. See [CENG0336] for details. 3 Note that in a multi-TRX BTS (available in SR2.0 onwards), only the master unit can be adjusted by this means; slaves automatically adjust their clocks to the master. 4 You can use BTS Installer to determine whether a nanoBTS is multi-TRX capable or not using the Fetch HW & SW Configuration button: if the nanoBTS is not multi-TRX capable, the Equipment Version will be 108_029 or 110_029; all other values of Equipment Version are multi-TRX capable.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 71 - The normal process for manual frequency adjustment is for the user to: • connect external frequency measuring equipment to the nanoBTS TIB out port using the correct type of cable • use the Frequency Control command to change the Frequency Control attribute whilst observing the effects using the external measuring equipment • stop when the nanoBTS is set to the required frequency (26MHz for nanoBTS models that are not multi-TRX capable, 1.625 MHz for nanoBTS models that are multi-TRX capable) within the required tolerance. Selection, connection, calibration and use of external frequency measuring equipment is beyond the scope of this User Guide. The external Frequency Counter should, however, be referenced to an accurate and stable source such as a Rubidium or GPS reference. PRIOR TO CALIBRATION THE nanoBTS SHOULD BE POWERED UP FOR A MINIMUM OF 10 MINUTES TO ALLOW IT TO STABILISE When the Frequency Control button is clicked, BTS Installer first checks the unit’s Up Time. If the unit’s Up Time cannot be determined (for example if the BTS is running pre-SR2.0 software), BTS Installer displays a warning message, “The nanoBTS’s Up Time could not be determined. The nanoBTS’s internal oscillator may not have settled sufficiently for frequency adjustment to be sufficiently accurate. It is recommended that frequency adjustment be carried out only after the nanoBTS has been running for at least 24 hours. Do you wish to continue?” with an OK button and a Cancel button. If the unit’s Up Time is less than 10 minutes, BTS Installer displays a warning message, “Up Time is less than 10 minutes. The nanoBTS’s internal oscillator is very unlikely to have settled sufficiently for frequency adjustment to be sufficiently accurate. It is recommended that frequency adjustment be carried out only after the nanoBTS has been running for at least 24 hours. Do you wish to continue?” with an OK button and a Cancel button. If the unit’s Up Time is equal to or greater than 10 minutes but less than 24 hours, BTS Installer displays a warning message, “Up Time is less than 24 hours. The nanoBTS’s internal oscillator may not have settled sufficiently for frequency adjustment to be sufficiently accurate. It is recommended that frequency adjustment be carried out only after the nanoBTS has been running for at least 24 hours. Do you wish to continue?” with an OK button and a Cancel button.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 72 - If the unit’s Up Time is equal to or greater than 24 hours, or if a warning message has been displayed and the user has selected the OK button, the Frequency Control dialog box is displayed, as shown in Figure 44 below. Figure 44 - Frequency Control dialog box BTS Installer automatically reads from the BTS all of the values for this dialog box when it is first displayed. The Timing Bus group box contains read-only information about clock sources and the status of the timing bus. It contains a Refresh button, which when clicked causes BTS Installer to fetch the latest values for clock sources and status from the nanoBTS and update the display as necessary. The Clock Sources group box lists the possible clock sources and indicates for each one:

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 73 - • whether it is supported on the nanoBTS unit in question • whether it is currently available (ie. whether a clock source is present) • whether it is currently the active clock source (ie. the one that the unit is taking its timing from) On nanoBTS models that are not multi-TRX capable, the Internal OCXO is always supported, available and active, and neither TIB Clock Input nor 10 MHz Input are supported. On other nanoBTS models, all three sources are supported. The Status group box indicates, for the currently active clock source: • whether GSM frame pulses are being received (these are only expected if the active clock source is TIB Clock Input) • whether GSM frame numbers are being received (again, only expected if the active clock source is TIB Clock Input) • whether the external clock input is valid (this applies only if the active clock source is either TIB Clock Input or 10 MHz Input) The Status group box also indicates whether timing bus output control is supported. On nanoBTS models that are not multi-TRX capable, it is never supported. On other nanoBTS models, it is supported on a master, but not on a slave. The TIB Output group box contains a set of three radio buttons that allow the user to choose between automatic, enabled and disabled. These buttons are only enabled if timing bus output control is supported. Clicking the spin controls (the buttons with up and down arrows) on this dialog box adjusts the OCXO frequency up or down by 100, 10 or 1 ppb. These spin controls are only enabled if the TIB Output is set to enabled. Each change is sent to the nanoBTS immediately, so the user can see the effect on the nanoBTS’ frequency immediately using the external frequency measuring equipment. When the desired frequency has been reached press the Close button; a note of the starting and ending values of the Frequency Control is made in the log. A nanoBTS’s frequency can only be adjusted manually if Internal OCXO is the active clock source. If the Internal OCXO is not the active clock source and the nanoBTS being adjusted is a master, remove its 10 MHz input. If the active clock source shown in the Clock Sources group box is not Internal OCXO, BTS Installer disables the Frequency Control spin controls. However, since this display is only refreshed by user action, it can be out of date. If the user attempts to use the spin controls to adjust the frequency of a nanoBTS that has an active external clock source, the nanoBTS rejects the update and BTS Installer displays an error message indicating “resource not available” in the progress bar on the Frequency Control dialog box. In order to be able to monitor the frequency of a master’s TIB Out signal while making adjustments, the user may have to change the TIB Output setting to Enabled. It is the user’s responsibility to ensure that the TIB Output setting is restored to the previous value (if that is what is required) when adjustment is complete. If when the user closes the Frequency Control dialog box, the TIB Output setting is different from when the dialog box was opened, BTS Installer displays a warning to that effect and gives the user the option to confirm or cancel.

When the button is pressed, BTS Installer fetches some attributes from the nanoBTS and then displays this dialog: The Security Possible attribute is a read-only attribute which indicates whether the nanoBTS is capable of making secure connections. If the nanoBTS is not capable of making secure connections because it is running a version of software which does not have this feature then “(not present)” will be displayed. If the nanoBTS does have security capable software running then the value will be one of: • No certificate – no certificate has been downloaded to the nanoBTS and it is unable to make secure connections. • Certificate available – a certificate has been downloaded to the nanoBTS, but the nanoBTS has not been resent since the download of the certificate. The nanoBTS is unable to make secure connections but should become able to make secure connections if it is reset. • Certificate in use – a certificate has been downloaded to the nanoBTS and is in use. The nanoBTS is able to make secure connections. The SSL Control attribute is a configurable attribute which instructs the nanoBTS how it is allowed to make connections. This attribute cannot be configured from BTS Installer; ways to configure it include using Config Manager. If the nanoBTS is running a version of software which is capable of making secure connections the value displayed will be one of: • Security Disabled – the nanoBTS will not make secure connections • Security Optional – the nanoBTS will make secure (SSL) connections if possible, or insecure connections if secure connections cannot be made • Security Mandatory – the nanoBTS will only make secure (SSL) connections; if it cannot make secure connections it will refuse to make insecure connections.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 75 - Note that as for some other non-volatile (NV) attributes there are two versions of the SSL Control attribute on the nanoBTS – the “NV” version, which says what the nanoBTS will do next time it is reset, and the “current” version, which says what it is doing now. BTS Installer displays the current version. If the value of SSL Control is changed by some means, for example by using Config Manager, but the nanoBTS is not reset then there will be no change to the value of SSL Control displayed on this dialog until after the nanoBTS has been reset. The Manufacturer Serial Number of the nanoBTS is displayed. This is used in working out the name of the certificate .sdp file which BTS Installer will attempt to locate in the .zip file which the user has specified on the Download tab of the BTS Configuration dialog. If the .zip file does not contain a certificate for this individual nanoBTS then it is this serial number that should be used, via whatever administrative procedures are in place, to locate or request the certificate for the nanoBTS. If a Certificate Revocation List has ever been downloaded to the nanoBTS then its timestamp is displayed. BTS Installer will refuse to download a certificate revocation list to the nanoBTS unless it has a later timestamp than the one already in the nanoBTS. The Certificate Download Status displays the results of several checks that BTS Installer has performed on the .zip file specified by the user on the Download tab of the BTS Configuration dialog. This includes checking that the .zip file does contain a certificate for the nanoBTS as determined by its Manufacturer Serial Number. If the certificate file appears valid, the Download Certificate button is enabled. This will attempt to download the certificate to the nanoBTS. However this process is not guaranteed to succeed – one reason for failure would be if the Security Possible attribute’s value wasn’t “No Certificate”, as it is only possible to download a certificate to a nanoBTS which doesn’t already have one. The CRL Download Status displays the results of several checks that BTS Installer has performed on the certificate revocation list .sdp file specified on the Download tab of the BTS Configuration dialog (or the most recent CRL found if no file name is specified). If the CRL file appears valid, the Download CRL button is enabled. This will attempt to download the certificate revocation list to the nanoBTS.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 76 - 6.6 The DHCP Server 6.6.1 Function of the DHCP server The DHCP server can supply the following information to a nanoBTS which does not have an IP configuration: • IP address • subnet mask • default gateway. This information is necessary for the nanoBTS to be able to communicate with the other functions of BTS Installer and with the BSC. Details of how to design an IP network for nanoBTSs are outside the scope of this User Guide. 6.6.2 Prerequisites for the DHCP server to work The DHCP server will not offer IP addresses except where it is absolutely certain that you want it to do so – it is very careful to avoid disrupting the operation of other DHCP servers that may be on the local area network. At any stage, if BTS Installer’s built-in DHCP server is at all unsure that it should be offering an IP address to a particular device, it will not offer any address. Hint: If BTS Installer’s DHCP server is not giving a BTS an IP address when you think it should be, first look in the BTS Database pane and check the indicator in the DHCP column for the BTS in question. If the indicator is grey (rather than yellow, red, or green), BTS Installer will not try to give out an IP address, because you haven’t ticked the Enable DHCP Configuration check box on the DHCP tab of the BTS Configuration dialog box: click the Edit button to bring up the dialog box and then correct the problem. In addition there are a number of network configuration issues that can stop the DHCP server from working. A complete discussion of DHCP network design is outside the scope of this User Guide, but some requirements and pitfalls are mentioned below. In order for the DHCP server to succeed in allocating an IP address to a nanoBTS all the following conditions must be met: • There must be an entry for the nanoBTS in the BTS Database – see section 6.3.1. • The MAC address in the BTS Database entry must match the MAC address of the nanoBTS; normally this is as printed on the bar code label attached to the nanoBTS. (Alternatively, if BTS Installer is in Unknown BTS Mode – see section 6.3.3.2 – then a request from any nanoBTS will be accepted regardless of MAC addresses matching.) • The nanoBTS must have its various flags correctly configured to use DHCP to acquire an IP address, see section 6.7.9. • The DHCP configuration phase for this nanoBTS must be enabled – see the Hint above (and more details in sections 6.3.2 and 6.4.6)

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 77 - • The DHCP server must have an IP address to offer to the nanoBTS, either configured explicitly or chosen from a pool, as described below, and the subnet mask and default gateway for the nanoBTS must be specified. • The DHCP server must know the IP address of the interface on which it is to respond to requests – see section 6.5.1.2. • The DHCP server must be running – when it is running the Start button will be disabled and the Stop button will be enabled. • There must be a network connection between the nanoBTS and BTS Installer that allows the relevant broadcast UDP messages to be sent and received; typically this will be the case if they are both on the same local area network, or if all routers between them are running an appropriately configured BOOTP Relay Agent. • There must be no software, for example a personal firewall, running on the machine with BTS Installer that blocks packets incoming to UDP port 67 (which the firewall might list as "DHCP server" or "BOOTP server") or packets outgoing from UDP port 68 (which the firewall might list as "DHCP client" or "BOOTP client"). Also under no circumstances will BTS Installer’s built-in DHCP server offer an IP address to any device that doesn’t appear to be a nanoBTS. This is achieved by checking that the device quotes a Vendor Class Identifier that matches a known string, all of which currently start with “com.ipaccess.nanobts”. 6.6.3 Assigning an IP address to a nanoBTS There are two ways in which you can tell the DHCP server which IP address to allocate to a nanoBTS: • If there is an explicit IP address specified on the “BTS” tab of the “BTS Configuration” dialog box box then the DHCP server will offer this IP address to the nanoBTS. Choose this option if it matters to you exactly which nanoBTS gets which IP address. • Otherwise, if there are any unused addresses in its IP Address Pool, the DHCP server will choose one of these to offer to the nanoBTS. Choose this option if you don’t mind which nanoBTS gets which IP address, within a particular set of addresses. The IP Address Pool is a set of IP addresses which you specify as being available to the DHCP server for it to offer to nanoBTSs. (If you allocate an explicit IP address to all nanoBTS then the pool is not used and can be empty.) There are two ways to get IP addresses into the IP Address Pool: • From the configuration file. • By editing the pool using the Pool button. See section 6.5.2.2 for details on how to edit the IP address pool. In the IP address pool display, a red colour, showing that a nanoBTS has rejected this IP address, might indicate a network configuration problem. The most likely reason for a nanoBTS to reject an IP address is that it has discovered that some other device on the network is already using this address; trying to use the same address twice suggests a network configuration error.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 78 - 6.6.4 Other IP configuration parameters In addition to giving each nanoBTS a unique IP address it is necessary to specify the subnet mask and default gateway that each nanoBTS will use. Normally you will want to set the same values for these parameters for all the nanoBTSs on a particular network. These parameters are set on the DHCP tab of the BTS Configuration dialog box, either for the particular nanoBTS or for all nanoBTSs using the Defaults button. See section 6.7.7 for a description of the DHCP tab of the BTS Configuration dialog box, and section 6.7.4 for a description of how the system of default values works. 6.7 BTS Attribute Reference This section gives a complete reference to the BTS Configuration dialog box (Figure 45) and to all the attributes that can be specified for a nanoBTS, or as default values for all nanoBTSs, whether via the BTS Configuration dialog box or via a configuration file. Figure 45 - BTS Configuration dialog box 6.7.1 The BTS Configuration Dialog box The BTS Configuration dialog box can be displayed in any of the following ways:

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 79 - • Select an entry for a nanoBTS in the BTS Status section of the user interface and press the Edit button – this produces a BTS Configuration dialog box that allows the attributes for that particular nanoBTS to be edited. • Press the Defaults button – this produces a BTS Configuration dialog box that allows the user to edit default values that BTS Installer will use for all nanoBTSs that don’t have specific settings. • Press the Edit button from the Configure BTS dialog box (which in turn is produced by pressing the Action button) – this produces a BTS configuration dialog box that allows the attributes for the particular nanoBTS to be edited in exactly the same way as the Edit button in the main user interface. There are various other occasions on which BTS Installer considers that the user is likely to want to edit or view nanoBTS attributes and it then pops up the BTS Configuration dialog box as part of a longer process. Examples include: • When the user uses the New button to create a new BTS Database entry, the user will probably need to enter some attributes for this nanoBTS before the new BTS Database entry is useful for anything, so the BTS Configuration dialog box for the new BTS Database entry is displayed automatically. • When the Set/Get NV Attributes button is used it is likely that the user will want to inspect the values fetched from the nanoBTS, so the BTS Configuration dialog box is displayed automatically. The nanoBTS attributes are accessed from the BTS Configuration Dialog box and changes that have been made are saved by selecting the OK button. Selecting the OK button removes the BTS Configuration Dialog box. The BTS Configuration Dialog box can also be removed by selecting the Cancel button. This will lose any changes that have been made to the nanoBTS attributes.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 80 - 6.7.2 Current Values Display The BTS Configuration dialog box can show just the attribute values that the user wants to configure on the nanoBTS, as in Figure 45, or it can be expanded by selecting the “Current values >>” button to also show the current values of the attributes in the nanoBTS, if these are known, as shown in Figure 46. Figure 46 - Expanded BTS Configuration dialog box BTS Installer may know about up to three possibly different values for each attribute, and these are displayed in three columns in the dialog box. Left Desired values These are the values (specified by the user or by default) that will be configured in the nanoBTS next time a manual or automatic NV configuration phase is run. Middle NV values in BTS These are the values held in non-volatile memory in the nanoBTS. These may not be the values currently in use, as for some attributes any new values are only used when the nanoBTS is restarted. Right Current values in BTS These are the values currently being used by the nanoBTS. The Desired values are as specified by the user, either in the BTS Configuration dialog box or in a configuration file, or may be default values. See section 6.7.4 for a description of how BTS Installer looks for default values for any attributes that have not been explicitly specified. The NV values in BTS are only present if these have been fetched from the nanoBTS, and depending on when they were last fetched from the nanoBTS the values

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 81 - displayed may or may not be up to date. These values are fetched from the nanoBTS as follows: • When automatic configuration of the nanoBTS is performed, and the non-volatile attributes configuration phase is enabled, then any non-volatile attributes that are configured on the nanoBTS are read back. BTS Installer does this to check that the values set have been correctly stored by the nanoBTS. Attributes which are not being set are also not read back, so in a typical automatic configuration run only some of the “NV values in BTS” are fetched. • When the manual Set/Get NV Attributes command is run some or all of the NV values in BTS will be fetched from the nanoBTS, as specified by the user (see section 6.5.5.4). The Current values in BTS are only present if these have been fetched from the nanoBTS, and depending on when they were last fetched from the nanoBTS the values displayed may or may not be up to date. These values are fetched from the nanoBTS as follows: • When the manual Set/Get NV Attributes command is run some or all of the Current values in BTS will be fetched from the nanoBTS, as specified by the user (see section 6.5.5.4). Note that only the Desired values of attributes are ever read from or stored to configuration files. The NV values in BTS and Current values in BTS are never present in configuration files. For some attributes there is no useful concept of any “current value” in which cases no current values are shown on the expanded dialog box. The BTS Configuration Dialog box can be returned to displaying only the Desired values by selecting the << button. 6.7.3 Identifying a nanoBTS There is no single nanoBTS parameter that can always be used to uniquely identify a nanoBTS’ configuration data in the BTS Database, thus the most appropriate parameter to regard as the “identity” of the nanoBTS will vary depending on what the user is doing: • During physical installation of nanoBTS, ie actually screwing them to the wall, the Location string is likely to be the most useful identifier, and if a configuration file is prepared in advance it will most likely identify the nanoBTS by the Location string. At this point the configuration file probably doesn’t contain a MAC address for the nanoBTS, as this would unnecessarily constrain the installer to install specific units at specific locations. • When a nanoBTS is physically installed the installer can make a note of the MAC address of the nanoBTS installed at each location, and can edit the configuration file or the BTS Database to add this information for each nanoBTS. The MAC address now becomes the most useful identifier for a nanoBTS, as it is the MAC address that the DHCP server component of BTS Installer uses to work out what data to send to which nanoBTS. • Once the DHCP process has run, if desired, each nanoBTS will know its IP address. At this point the IP address becomes the most useful identifier for a

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 82 - nanoBTS, as it is the IP address that BTS Installer will use to contact each nanoBTS for later configuration phases. In addition, when BTS Installer connects to a BTS via a Primary OML Proxy, BTS Installer identifies the nanoBTS it wants to talk to by quoting the Unit ID to the proxy, so in this case it is the Unit ID that is the most useful identifier for the nanoBTS. See section 6.9 for more information about proxy mode. BTS Installer does not therefore require that any of these parameters have unique values, as to do so would restrict the usefulness of the tool in some circumstances. 6.7.4 How Defaults Work You do not need to enter a value for every parameter for every nanoBTS to be configured; most parameter values can be picked up using BTS Installer’s system for handling default values. When BTS Installer wants to know the value of a parameter to apply to a particular nanoBTS: • First it will look in the BTS Database entry for that nanoBTS, to see whether a value has been specified explicitly for that nanoBTS, either in a [BTS:<location>] section in the configuration file or manually via the user interface; • If it doesn’t find an explicit value for that nanoBTS it will look at a special “default” BTS Database entry, which the user can set in the [Default] section in the configuration file or via the Defaults button on the user interface • If the user hasn’t specified a Default value then a built-in default value will be used. The built-in default values are mostly things like zero, null strings, “off” or “don’t”. If the user specifies no parameters at all then BTS Installer will do nothing at all, and thus will do nothing harmful. In a typical installation there will be several parameters which will have the same settings for all nanoBTS, for example the router (default gateway) DHCP parameter. The user is recommended to set these as default values using the [Default] section in the configuration file or the Defaults button on the user interface; it will not then be necessary to specify these values separately for each nanoBTS. Note however that if you use the Edit button (or some other means) to edit the configuration for a nanoBTS what you will see in the dialog box is not just the parameters you have specified explicitly for this nanoBTS but the result of merging values from all three of the sources above. If you change a default value using the Defaults button then you will change what you see in the dialog box for those nanoBTSs that do not have an explicit setting for this parameter. 6.7.5 Enabling Configuration Phases The various configuration phases can be enabled and disabled separately, and whether each phase is enabled or disabled is indicated by the various tabs of the BTS Configuration dialog box, which are grey if the relevant phase is enabled or white if the relevant phase is disabled.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 83 - Each phase is enabled or disabled by a check box which is the first item on the first tab for that phase. Tab Phase Check box to enable this phase BTS None N/A DHCP DHCP Enable DHCP Configuration Unit ID Unit ID Configure Unit ID NV Attr (1) Non-volatile attributes Enable NV Attr Configuration NV Attr (2) Non-volatile attributes (see NV Attr (1)) NV Attr (3) Non-volatile attributes (see NV Attr (1)) NV Attr (4) Non-volatile attributes (see NV Attr (1)) Download Download Enable Download The BTS tab contains information to identify the nanoBTS and is not part of any configuration phase. 6.7.6 The BTS tab The BTS tab, Figure 47, contains information to identify the nanoBTS. Figure 47 - BTS tab Attribute Description MAC Address The MAC address of the nanoBTS, if known IP Address The IP address of the nanoBTS, if explicitly specified See also section 6.7.3 for a discussion of the various ways in which a nanoBTS can be identified at various stages of configuration. The MAC address is displayed only if it is known to BTS Installer; otherwise a dummy default address is displayed. If BTS Installer does not have to give the nanoBTS an IP address using its built-in DHCP server then it never needs to know the nanoBTS’ MAC address. So: • If you want BTS Installer’s DHCP server to allocate an IP address to this nanoBTS, fill in the MAC address of the nanoBTS here. • If this BTS Database entry has been created by the Find command the MAC address will be filled in automatically for you. • Otherwise ignore this attribute.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 84 - The IP address is displayed only if an IP address for this nanoBTS is known to BTS Installer and the IP address has not been allocated by BTS Installer’s built-in DHCP server from the IP Address Pool. So: • If you know the IP address of this nanoBTS, because it has already been allocated by some means external to BTS Installer, fill in the known IP address here. • If you want BTS Installer to allocate a specific IP address to this nanoBTS using its DHCP server, fill in the desired IP address here. • If you want BTS Installer to allocate an IP address from a pool to this nanoBTS, but don’t care which particular IP address it gets, leave this set to 0.0.0.0. • If this BTS Database entry has been created by the Find command the IP address will be filled in automatically for you. • If this BTS Database entry has been created via an IP address on BTS Installer’s command line, perhaps because BTS Installer has been run directly from Config Manager, the IP address will be filled in automatically for you. Note that if you want to change the nanoBTS’ IP address you can not do this simply by changing the IP address on this tab. If you enter a changed IP address here it will be used to reconfigure the nanoBTS’ IP address but only if and when the nanoBTS tries to renew its IP address lease with BTS Installer’s DHCP server. In most circumstances the Change IP Configuration command (see section 6.5.5.9) is a more appropriate way to try to change a nanoBTS’ IP address – this will also change the IP address displayed in the BTS tab.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 85 - 6.7.7 The DHCP tab The DHCP tab, Figure 48, contains attributes to control the operation of the DHCP server with respect to this nanoBTS. In addition, if the DHCP configuration phase is enabled, the MAC address from the BTS tab is used by the DHCP server and the IP address from the BTS tab may be used by the DHCP server. Figure 48 - DHCP tab Attribute Description Enable DHCP Configuration Enables or disables the DHCP configuration phase; when disabled the DHCP tab is white and the remaining attribute controls on this tab are disabled. IP Lease Time How long the IP address given to the nanoBTS by the DHCP server is valid. See discussion below. Subnet Mask The subnet mask that the nanoBTS uses as part of its IP configuration. This may be left at zero if it can be deduced from the class of the IP address. Details of the design of IP networks are outside the scope of this User Guide. Router The router, or default gateway, that the nanoBTS uses as part of its IP configuration. Details of the design of IP networks are outside the scope of this user guide. The IP Lease Time specifies how long the IP configuration supplied to the nanoBTS by BTS Installer’s DHCP server is to be valid. Before this period expires the nanoBTS will contact the DHCP server asking for the lease to be renewed; if the DHCP server doesn’t reply, perhaps because BTS Installer isn’t running any more, then when the period expires the nanoBTS will regard its IP configuration as invalid, will restart, and will try again to find a DHCP server willing to give it a valid IP configuration. Whilst BTS Installer can be used as a permanently running (24/7) DHCP server to serve IP configurations to a network of nanoBTSs it is not designed or intended to be used in this way. This means that it is only sensible to set a finite lease time in particular circumstances, for example:

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 86 - • If BTS Installer is being used to connect to this nanoBTS in a temporary network configuration in order to perform some configuration of the nanoBTS before it is deployed to its final location then a finite lease is acceptable, as the nanoBTS does not need to continue to operate once BTS Installer has stopped running. • If some other DHCP server is available on the network that will take over the job of BTS Installer’s built-in DHCP server once BTS Installer has stopped running. When the intention is to use BTS Installer’s built-in DHCP server to give a nanoBTS a permanent IP address and IP configuration that it will remember across restarts, so that the nanoBTS will continue to operate correctly in the absence of any DHCP server on its network, it is necessary to: • Set the lease time to infinite, by specifying a time of –1 seconds. • Set flags F1, F2 and F3 to ON to ensure that the nanoBTS does not make more DHCP requests if and when it is restarted; see section 6.7.9 for details of these flags. Note that if you want to change the nanoBTS’ IP configuration you can not do this simply by changing the attributes on this tab. If you enter changed attributes here they will be used to reconfigure the nanoBTS’ IP configuration but only if and when the nanoBTS tries to renew its IP address lease with BTS Installer’s DHCP server. In most circumstances the Change IP Configuration command (see section 6.5.5.9) is a more appropriate way to try to change a nanoBTS’ IP configuration – this will also change the attributes displayed in the BTS tab and the DHCP tab.

Figure 49 - Unit ID tab Attribute Description Configure Unit ID Enables or disables the Unit ID configuration phase; when disabled the Unit ID tab is white and the remaining attribute controls on this tab are disabled. Unit ID The Unit ID for the nanoBTS, see discussion below. Reset BTS After Setting Whether to restart the nanoBTS after setting its Unit ID. If this is checked, then during automatic configuration BTS Installer will reset the nanoBTS, will wait for it to restart, and will wait (if appropriate) for it to repeat its DHCP transaction before continuing with further configuration phases. The Unit ID is used by the nanoBTS to identify its role in the system and to identify itself to the BSC. The desired Unit ID for each nanoBTS should be determined as part of the network design; this process is outside the scope of this User Guide. Note that until a nanoBTS has a Unit ID configured it will not know its role in the network (whether it is a SITE manager, whether it contains a BTS object, whether it is a master TRX or a slave TRX) and many of its functions will be unavailable. From the point of view of BTS Installer, it will not be possible to software activate a nanoBTS that does not have a Unit ID configured, and hence it will not be possible to perform Network Listen operations.

Figure 50 - NV Attr (1) tab Attribute Description Enable NV Attr Configuration Enables or disables the NV attribute configuration phase; when disabled all the NV Attr tabs are white and the remaining attribute controls on these tabs are disabled. Configure Flags Whether to send new values for the NV Configuration Flags to the nanoBTS F1 to F14 For each flag the user can choose “Not Set”, in which case the value of this flag on the nanoBTS will be unchanged, or “OFF” to switch this flag off on the nanoBTS or “ON” to switch this flag on on the nanoBTS. See table below for the meaning of each flag. Flags that are missing from the numerical sequence are not currently used, except for F4 which is automatically generated by BTS Installer for the benefit of older nanoBTS software that needs a value for this flag.

F7, F13 and F14 take immediate effect. Flags F9-F12 immediately affect the ability of the BTS to accept new connections for the specified services, but may not terminate any existing connections.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 90 - 6.7.10 The NV Attr (2) tab The NV Attr (2) tab, Figure 51, contains additional non-volatile attribute settings. All the controls on this tab are disabled unless the Enable NV Attr Configuration check box on the NV Attr (1) tab is checked. Figure 51 - NV Attr (2) tab Each non-volatile attribute, or group of attributes, may be included or omitted when the non-volatile attribute configuration phase takes place. (This grouping of attributes is based on the grouping of attributes in the GSM 12.21 protocol used to communicate with the nanoBTS.) There is a check box to enable sending of each attribute or group of attributes: when this is not checked the controls for the corresponding attributes are disabled.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 91 - Attribute Description Configure Primary OML List Whether to send new values for the Primary OML List to the nanoBTS.s Number of Addresses in List The Primary OML List contains up to two IP Addresses and Ports; this may be set to zero, one or two list entries.5 Primary OML IP Address The IP address to which the nanoBTS should try to connect to set up its primary OML connection, typically the address of the BSC. This control is only enabled if Number of Addresses in List is set to at least one. Primary OML TCP Port The TCP port that the nanoBTS should use when trying to connect to the above address. If this is set to 0, the nanoBTS will use its built in default value. Primary OML IP Address 2 A fallback IP address to which the nanoBTS should try to connect to set up its primary OML connection if the attempt to connect to the Primary OML IP Address failed. This control is only enabled if Number of Addresses in List is set to 2. Primary OML IP Port 2 The TCP port that the nanoBTS should used when trying to connect to the above address. Configure Primary OML Fallback Timeout Whether to send a new value for the Primary OML Fallback Timeout to the nanoBTS. Primary OML Fallback Timeout This is the number of seconds for which the nanoBTS should attempt to contact the Primary OML IP Address before giving up and trying to contact the Primary OML IP Address 2. If this value is zero the nanoBTS will only make one attempt to contact the first IP address before moving on to try the second. Configure Secondary OML Whether to send new values for the Secondary OML IP Address and Secondary OML TCP Port to the nanoBTS. Secondary OML IP Address If this address is set, it is the only IP address which the nanoBTS will allow to make secondary OML connections; if it is not set, ie if it is left at 0.0.0.0, incoming secondary OML connections will be allowed from any IP address. Note that BTS Installer uses the secondary OML connection to talk to the nanoBTS, so if this attribute is set to something other than the IP address of the BSC you may find that BTS Installer is not able to perform further operations on this nanoBTS. Secondary OML TCP Port This is the TCP port on which the nanoBTS listens for incoming secondary OML connections. BTS Installer does not provide any means for changing this attribute. If the port on which the nanoBTS listens for incoming secondary OML connections is changed using some other tool then BTS Installer will not be able to connect to that nanoBTS, as it always tries to connect to the default port. 5 When configuring the Pimary OML List, the list of IP addresses (and optionally, ports) entered by the user will overwrite the BTS’s existing list (rather than adding to the BTS’s list). So, for example, to add a fallback OML IP address, the user must enter the existing Primary OML IP Address as well as a Primary OML IP Address 2. If you need to do this for several BTSs, you can do it in one go by using the Defaults facility (section 6.7.4 describes how this works).

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 92 - Attribute Description Configure Location Whether to send a new value for the Location to the nanoBTS. Location A text string that can be used to describe the physical location of the nanoBTS. This string will be recovered during the Find operation described in section 6.5.4.2.1. Configure Unit Name Whether to send a new value for the Unit Name to the nanoBTS. Unit Name A text string that is used as the nanoBTS’ DNS host name. 6.7.11 The NV Attr (3) tab The NV Attr (3) tab, Figure 52, contains additional non-volatile attribute settings. All the controls on this tab are disabled unless the Enable NV Attr Configuration check box on the NV Attr (1) tab is checked. Figure 52 - NV Attr (3) tab This tab contains the SNMP settings. There is an overall enabling check box, Configure SNMP Properties, to say whether any of the SNMP configuration should be sent to the nanoBTS, and if that is checked there are separate check boxes to control the sending of each individual part of the SNMP configuration. (Again, this reflects the options available in the underlying GSM 12.21 protocol.) Attribute Description Configure SNMP Properties Whether to send new values for any of the SNMP attributes to the nanoBTS. If this is not checked all the rest of the attributes on this tab are disabled.

SNMP Community String A text string. Meanings of the various SNMP configuration attributes are outside the scope of this User Guide. Set Trap Address Whether to send a new value of the SNMP Trap Address to the nanoBTS. SNMP Trap Address IP address Set Trap Port Whether to send a new value of the SNMP Trap Port to the nanoBTS SNMP Trap Port Port number Set Manager Address Whether to send a new value of the SNMP Manager Address to the nanoBTS.

All the controls on this tab are disabled unless the Enable NV Attr Configuration check box on the NV Attr (1) tab is checked. Figure 53 - NV Attr (4) tab This tab contains thresholds for various alarms that the nanoBTS can raise. Attribute Description Configure Alarm Threshold List Whether to send a new value for the Alarm Threshold List to the nanoBTS. Input Supply Voltage Thresholds for the input supply voltage alarm Internal Temperature Thresholds for the internal temperature alarm Input Supply Current Thresholds for the input supply current alarm Input Supply Power Thresholds for the input supply power alarm Each measured quantity can cause an alarm to be generated if it falls below the Lower Threshold or rises above the Upper Threshold. Any of these alarms can be turned off using the Off check box. When the Off check box is not checked the threshold is entered as a percentage of the nominal working range of the value. For example, for a unit with a nominal input supply voltage range 40V – 56V, setting the input supply voltage upper threshold to 90% would give rise to an alarm when the voltage was above 40 + 0.9 * ( 56 – 40 ) = 54.4 V Each percentage value can be between –20% and 120%.

© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 98 - 6.7.13.1 Download Software Attribute Description Enable Download Whether the download configuration phase is enabled. Download Software Specifies that it’s software that is to be downloaded File Name The name of the file containing the software to be downloaded to the nanoBTS. The Browse button produces a standard file selection dialog box (Status display) The Details button will open a dialog box displaying the content of the selected file, see Figure 55 for an example. Make New Software the Default If this is checked then the new software will be made the default after downloading. This means that next time the BTS restarts it will load and run the newly downloaded software. Reset BTS After Download If this is checked then the nanoBTS will be reset after downloading the new software, and will load and run the new software. Figure 55 - Software details dialog box 6.7.13.2 Download Certificate It is necessary to download a personalised certificate to each BTS that is going to communicate via a secure (SSL) connection to the BSC (and/or BTS Installer). Field Description Enable Download Whether the download configuration phase is enabled. Download Certificate Specifies that it’s the nanoBTS’ certificate that is to be downloaded File Name The name of the file containing the certificate to be downloaded to the nanoBTS. The Browse button produces a standard file selection dialog box (Status field) Displays a message if there is a problem with the selected file. Reset BTS After Download If this is checked then the nanoBTS will be reset after downloading the new software, and will load and run the new software. Certificates for nanoBTSs are delivered in .zip files each of which may contain certificates for several BTSs. So, if certificates are to be downloaded to several BTSs, the .zip file may be set in the Defaults, and the correct certificate will be selected from the .zip file to download to each BTS.

$© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.doc - 99 - 6.7.13.3 Download Certificate Revocation List From time to time some certificates may be revoked and Certificate Revocation Lists issued for downloading to nanoBTSs. This will prevent the nanoBTS communicating with anything that quotes the revoked certificate. Field Description Enable Download Whether the download configuration phase is enabled. Download Certificate Revocation List Specifies that it’s a certificate revocation list that is to be downloaded File Name The name of the file containing the certificate to be downloaded to the nanoBTS. The Browse button produces a standard file selection dialog box Latest CRL Displays the name of the latest CRL found. Reset BTS After Download If this is checked then the nanoBTS will be reset after downloading the new software, and will load and run the new software. A Certificate Revocation List is delivered as a .sdp file with a filename that includes a timestamp. It is recommended that these file are installed to the same directory as the BtsInstaller.jar file; on a Windows system this might be somewhere like: c:\program files\ip.access\BTSInstaller If that is done then the “Latest CRL” field will show the file name of the latest CRL file in that directory, which will normally be the one that needs to be downloaded to the nanoBTSs. In this case there is no need to enter anything in the “File Name” field. However if it is desired to download a specific CRL then its name may be specified in the “File Name” field. To change the directory that BTS Installer searches for the latest CRL: • put a CRL file in the desired directory • type its name in the “File Name” field – at this point the “Latest CRL” field will be filled in automatically • blank out the “File Name” field again. From now on BTS Installer will look in that directory for certificate revocation list files. 6.7.13.4 Switch Software Versions and/or Reset BTS only When this option is selected BTS Installer queries the BTS for its software configuration and includes a list of installed and active software versions in the log. Field Description Switch Backhaul Software Versions If this option is checked and the BTS contains two Backhaul software images then the current image is switched. This will take effect, ie the newly selected image will run, next time the BTS is reset.$
