23 AS4020 STs AS4020 Subscriber Terminal Overview The AS4020 Subscriber Terminal (ST) portfolio includes subscriber terminal types for voice, and packet data. In general, the customer has access to the same range of facilities that are supported by a conventional copper pair. Type 42 subscriber terminals have the majority of the electronics in the Service Interface Unit (SIU) located inside the customer premises. This is connected to the outdoor unit by an IF drop cable. The ODU contains the RF components. The iST subscriber terminal have the majority of the electronics in the Outdoor Unit (ODU) and they are connected via a drop cable to the Indoor Unit (IDU) that contains the power supply and the customer interfaces. When an AS4020 system is planned, for overall RF capacity purposes an assumption will be made of either the average modulation rate to be achieved across all subscribers or a specific mix of modulation rates will be assumed across the subscribers. This introduces a new factor into ST installation procedures: a check needs to be made of the actual modulation rate achieved against the planned modulation. If this check is not carried out, the assumptions made for modulation at the planning stage are not verified, with the potential result of the achieved overall RF capacity being much less than the planned capacity, resulting in a reduced level of service for subscribers. In addition to establishing modulation rates for each subscriber, the RF Planning process will ensure that adequate fade margins are present in order to achieve adequate link availability figures. Fade margins are associated with two parameters – SNR and Receive (downlink) /Transmit (uplink) Level. In an interference free, or island deployment, these two parameters will be closely matched. However, in a deployment limited by interference levels (through external interference or aggressive frequency reuse), The two parameters will be influenced by different factors. The output of an RF Planning exercise will generate the following requirements relating to an individual ST deployment: • Expected Modulation Modes (uplink & downlink) – based on the Rx SNR predicted • Required SNR Margin above Modulation Mode switching threshold – to maintain planned overall system throughput under shallow fade conditions. Where average overall system throughput is a concern, a 0dB SNR Margin is considered adequate for standard internet access services – this is because as some users SNR degrades, others will improve maintaining an average system throughput. For a conservative approach to system planning, a 2dB SNR margin would be adequate. However, if a particular ST requires guaranteed high bandwidth for services such as video conferencing, then the SNR margin would be increased. The fade margin required to maintain link availability will depend on the actual availability level required plus the propagation conditions. This is typically between 6 and 12dB. Telephony For normal telephony services, these could typically include: • multi-frequency or loop-disconnect dialling • subscriber private metering • intrusion tone • malicious call interception. • caller line identification Note. Line reversal is not supported. All tones, tone cadences and announcements which are generated by the local exchange are passed transparently over the AS4020 system. Line feed voltage, ringing current and ringing cadence are generated by the ST equipment. The Customer Premises Equipment (CPE) is connected to the line interface sockets on the internal SIU.
605-0000-595 Subscriber Terminal Installation and Commissioning 24 The specific impedance of the NTU allows tests to be performed by the SIU to detect the presence of any attached CPE. Packet Data Packet Data using 10/100baseT Ethernet links The Type 42 P1 and iST offer an Ethernet service, which allows applications such as home Internet access and Virtual Private Networks (VPN) for business users. It is designed to operate with downlink speeds of up to 2Mbit/s and uplink up to 1Mbit/s, although the typical configured uplink rates will depend on the number of STs on the system. The system uses Ethernet bridging, which has the advantage of relaying frames based on their MAC address, and so allows higher level protocols such as TCP/IP and IPX to pass transparently across the system. In this manner, the system is easy to configure, and provides a link that is transparent to devices on the LAN at each end of the bridge. The system links Ethernets using self learning MAC bridging and supports the following features: • Ethernet IEEE 802.3 10baseT RJ45 connector • Transparent Bridging allows the use of TCP/IP, IPX and other protocols over the link. • Supports up to 480 P1V2 Subscriber Terminals per RF channel • RF packet throughput capacity up to 8.5Mbit/s downstream, 5.7 Mbit/s upstream IEEE 802.1q VLAN s The 802.1Q standard (VLAN tagging) is also supported by the system, which is a secure means of segmenting a network. The traffic between VLAN's is restricted, thereby providing secure boundaries and limiting the propagation of broadcast and multicast traffic. This means that any equipment supporting VLAN tagging will be able to connect to the Type 42 P1 , and present each VLAN id on a separate Ethernet segment for connection into the appropriate network. IEEE 802.1q VLAN support on the AS4020 and Router provides security isolation is required between these corporate customers by creating Corporate Virtual Private Networking and allows independent LAN traffic to be carried over a single physical interface. 802.1q VLAN adds an identifier to each ethernet packet to identify which VLAN it belongs to. A router supporting 802.1q provides multiple VLAN subinterfaces (and IP addresses) on a single physical Ethernet interface. VLAN security allows independent assignment (including duplication) of IP addresses between VLAN groups. VLAN security is used together to provide total security isolation of grouped Ethernets. Ethernet linking is via MAC bridging providing protocol transparency. The user interface is 10baseT on RJ45 socket. Overview of ST operation working on AS4020 Block Data Mode BDM is used on the radio interface and transmits blocks of data using a connectionless protocol BDM transfers data across the air interface in discrete sized blocks. The payload for a given destination may be contained within a single block (size permitting), or across multiple blocks. The data field spreading factor, modulation and coding rate may be allocated by the system on a per block basis to match the signal to noise ratio of the channel. In the uplink an ST is allocated up to 4 RWs for voice and up to 4RWs for packet to transmit on by the CT on a per slot basis. The block duration is fixed throughout the system.
AS4020 STs 25 RW Codes Each RF channel is composed of 16 RW codes: Each RW uses can de either 128kbit/s or 2 X 64kbit/s RW code 15 is used for initial ST link acquisition and for downlink transmission of the internal CTS channel which is used to signal to STs the availability of channels to use for uplink transmissions. The remaining RW codes are used for voice and/or data. The voice/data boundary is dynamic with RW codes only being used for voice when this is required due to voice calls in progress. This maximises the data carrying capacity of the system as RWs not being used for voice are automatically made available for data. Each ST has a permanent always-on RTS/CTS channel. When an ST wishes to send uplink traffic, it signals this on the RTS channel and receives in return a reply from the AS4020 CT on the CTS channel informing the ST of which RW(s) can be used for the uplink voice/data transmission. The AS4020 is thus able to arbitrate between RTS requests from all STs and decide on a priority basis which STs are allowed to make an uplink transmission. For the maximum ST load of 480 STs per AS4020,One or two RWs are reserved in the uplink direction for RTS channels. Note that the downlink part of each of these RWs is free to carry user data traffic. This means that a data only AS4020 application has 15 RWs available in the downlink and 13 or 14RWs available in the uplink for user data. The carrying capacity in bit/s will depend on the modulation type and FEC code used for transmission to each ST. A voice only AS4020 application has 13 or 14 RWs free in both the uplink and downlink directions for user voice calls. AS4020 delivers data services to individual STs at various data rates depending on the modulation and forward error correction (FEC) mode it is operating in. The mode used is dependant on the RF link quality which is measured as a ratio of received signal strength to noise level (signal to noise ratio – SNR). The higher the SNR, the higher the mode of operation and hence, the higher the data rate to the ST. Various factors influence the level of noise seen by the system. These include: · Thermal (background and intra-system) Noise · Interference (co and adjacent frequency channels) · Excessive Multipath (signals received from reflections) AS4020 dynamically adjusts its mode of operation on a per ST basis depending on a continually updated measure of SNR. This measure of SNR includes all factors as listed above.

37 Installation Pre-installation Before the ST is installed, the installation acceptance criteria should be established. These are outputs from RF Planning as listed above. They are in summary: o Corresponding STID o RF Channel/Pilot Channel o PN Code o Expected Downlink Modulation (FEC Mode) o Expected Uplink Modulation (FEC Mode) o Required Fade Margin o Required Downlink SNR These parameters can be input to STMon during installation. It is expected that the installer will be informed of these values via a job instruction relating to the particular ST to be installed.

605-0000-595 Subscriber Terminal Installation and Commissioning 40 Preparation Site Selection Site Readiness Verifying that the site is ready for the installation of the ST equipment. Check access to the building before unloading or unpacking the equipment. Outdoor Unit Important Installation Considerations Geographical deployment within guidelines: Just because a ST seems to get a link on an excessively long distance or on a side lobe to a sectored antenna, this doesn’t mean it will work reliably. Frequency (Radio) planning is essential for the area covered (including frequency sweep to identify possible interferers). Clear line of sight: This is the single most likely reason for an installation not to work. Check for: • Any buildings or large trees, especially ones close to the ST, which obscure the line of sight will significantly reduce the RF power, and could cause problems with reflections. Trees should be at least 50m from ST installation RF path. Although AS4020 can operate through trees,absorption losses for a single tree can increase the path loss 6-9dB and foliage movement due to wind can cause varying path losses degrading BER performance. Note: Trees exceeding a distance of 50 metres from the antenna are considered ineffective to the units' performance. • Place the outdoor unit as high as possible to avoid local clutter caused by people/vehicles/trees. Make sure the outdoor unit is actually pointed at the CT. Mounting height should normally be 5-7 metres above ground level. • Ensure that the antenna path has sufficient near field clearance (see 'Site Selection' below) • No other radio broadcasting units are likely to transmit across or into the antenna boresight and have a separation from Airspan equipment of at least 2m. • For efficient and reliable service it is suggested that the external mounting location of the outdoor unit be chosen such that once 'panned' for optimum signal level it observes the following criteria:- • Avoid obstructions such as adjacent walls or overhanging roof eaves, within 15° in the horizontal plane and 30° in the vertical plane (see figure below). • Ensure adequate clearance is allowed for 'panning' the outdoor unit. • The antenna is capable of being 'panned' with at least 15° of adjustment either side of the direction of the CT antenna. These guidelines should not be violated during the outdoor unit panning process. Physical separation: STs at the same location must have at least 1 metre separation between their outdoor units, to stop coupling between them causing interference. Correct orientation: The ST outdoor unit has a required orientation, mounting it at 90 degrees to this (e.g. by attaching it to a horizontal rather than vertical mounting bar) will affect the RF performance.
Installation 41 Before installing an outdoor unit a test ST should be used to check that the ST has sufficient fade margin and is able to deliver the target quality of service. The test outdoor unit is usually mounted on a telescopic pole and powered from a vehicle battery a drop cable connects to the SIU and the outdoor unit is pointed in the direction of the CT .Place the outdoor unit up against the building at the position where the outdoor unit is to be fixed and slowly pan the outdoor unit though the path of the CT until a signal is received. Check that the ST can acquire a link and that a make a test call over the system. Check for both way transmission and absence of noise and interference. If there are any problems with the reception and quality of the call then reposition the outdoor unit and repeat the process until a viable location is found. Outdoor Unit Positioning The mounting should be solid and firm, and the outdoor unit placed in a position where objects will not move in front of it, e.g. seasonal variations for trees (leaves, snow covering, growth), people walking across roofs, tall vehicles driving past, a new building being constructed in the line of sight, etc. Inspect the suitability of the wall structure for the installation position of the outdoor unit mounting. Typical acceptable structures are:- • Secure brick walls • Concrete cladding covered building blocks • Metal / wooden pole, with suitable bracket. Check how the drop cable is to enter the site and the internal drop cable run from the antenna to the internal SIU. Before commencing with the installation, confirm with the customer the following:- • Suitability of the outdoor unit position. • Entry point of the drop cable to the site. Keep the drop cable short: As the I/F frequencies are attenuated by the drop cable, any significant unused length should be cut off before termination. Also, use low loss drop cable for potentially marginal installations. • Internal cable run from entry point to the SIU.
605-0000-595 Subscriber Terminal Installation and Commissioning 42 ST W 802.11b Wireless Antenna Positioning To maximize the wireless coverage, place the unit as centrally as possible (depending on the wireless computer's vicinity) Power Availability Check with the customer the suitability of the SIU position - Within 1 metre of the AC power outlet and within 50/75 metres of the antenna (lengths of drop cable are 50 metres or 75 metres). Ensure a good power supply for the ST: Do not connected to intermittent supplies , e.g. central heating timers. This will shorten the battery life (if fitted) considerably as it is not designed to be constantly charged and discharged.

Installation 63 Installing Drop Cable Drop Cable Installation Drop cable is provided in two types 6 Series and 11 Series (low loss). Use this procedure to install the drop cable. STEP PROCEDURE 1. The drop cable is normally provided with one end already terminated with an weather proofed F-Type connector for use at the Outdoor Unit. The cable is manufactured in three lengths (25, 50 and 75metres) and an appropriate length should be selected. In some circumstances cable is provided on 300metre drums and both ends of the cable are terminated during installation. 2. If the drop is not pre-terminated and requires an F type terminating at the outdoor unit end. It is suggested that the F-Type connector is terminated to the free end of the cable before running the cable. See Drop Cable Termination (6 series) or Drop Cable Termination (11 series) 3. The cable is installed starting from the antenna end leaving the free end of the cable to be finally dressed into place and cut to length for neat connection with the power supply unit. 4. Run the drop cable from the outdoor unit end to the F-Type connector to the SIU. 5. The maximum drop cable distance between the SIU and the outdoor unit must not exceed the length of the drop cable (50 or 75 metres). 6. The 6 series cable has a minimum bend radius of 70mm. The 11 series cable has a minimum bend radius of 100 mm 7. Secure the drop cable to the antenna mounting bracket or pole using straps. Leave sufficient slack to allow for antenna panning at the commissioning stage. 8. Secure along the drop with 7mm cleats as required. Ensure that a drip loop is formed at the point where the cable enters the building to avoid the ingress of water into the building. 9. Plug the F-Type connector into the connector on the rear plate of the outdoor unit. Important Notice: Care should be taken when screwing the F-Type connector into the connector on the rear plate of the outdoor unit to ensure that the connector is not over-tightened as over-tightening will strip the thread. Use a torque spanner set to 2.3Nm. See figures below for pole mount and for wall mount installation. 10. a) Use rubber boot to provide environmental seal if provided as part of the installation kit Push the rubber boot over the connector and ensure that it mates properly with the raised plastic ring on the outdoor unit housing. Once the boot is in place a tie wrap should be placed around the cable behind the boot to ensure that the boot does no become displaced. or b) Wrap self amalgamating tape over the joint of the mated connector. When using self amalgamating tape, strip back the interleaving and stretch the tape by between one third and one half. Keep the tape under tension and wrap, overlapping successive layers by 50% until the desired build up of insulation is achieved. Finish the wrapping by holding the tape under the thumb and snap by stretching. The high degree of stretch as described above prevents the inclusion of voids and ensures rapid amalgamation. 11. Run cable end up to the SIU. Estimate the length of end required for termination of cable (allow 150mm of conductor for a maintenance re-termination of cable) and cut cable to length. 12. Terminate the drop cable. For termination instructions see Drop Cable Termination (6 Series) or Drop Cable Termination (11 Series)

Commissioning 173 Programming Type 42 ST using STMON Configure a Type 42 Subscriber Terminal If using STMON software the ST must be powered up and running its application software before attempting to configure a ST. The boot sequence should be complete within 1 minute of power on. Failure to do this results in the corruption of the ST operating software. Pilot Channels are pre-programmed directly to the ST using STMON as part of the ST installation process. STMON will allow an ST to have only one Pilot channel pre-programmed and this channel has to be within the ODUs operating range. The Target channel must also be within the operating range of the ODU. 1. Select the Setup tab and load the installation file. (For details on editing and creating installation files see the STMON help file.) 2. Select the Radio Data tab and click left mouse button on the Configure ST button. 3. Enter data into fields on the Configure ST window. 4. Enter the ST ID, this number must be unique for all STs sharing the same CT 5. Select the channels to be made available to the ST in the pilot channel list (left hand list) using the mouse and click the Add or click the Add All button if all channels are required. A maximum of ten channels may be selected. If an attempt is made to select more than ten then a warning message is displayed. The selected channels appear in the right hand list. Note: The channels in the pilot channel list (left hand list) are created using the Installation File Editor (see STMON help file). else the default list of all channels is loaded. 6. Select the scan channels. Double clicking a channel toggles the scan field. An X shows that the field is selected. The ST will only scan those channels where the scan has been enabled. At least one channel needs (exactly one channel for AS4000 configuration) to be enabled or the following message is displayed.

605-0000-595 Subscriber Terminal Installation and Commissioning 176 Panning Type 42 Outdoor Unit Using STMON Antenna Alignment Once configured and installed the ST Antenna /ODU will need to be panned to optimise the RF link quality- SNR, signal strength and fade margin. STEP PROCEDURE 1. If pole mounted place and tighten a tie wrap immediately underneath the pole bracket to prevent the assembly sliding down the pole. 2. Loosen the outdoor unit fixing bolts sufficient to allow the antenna to rotate around the pole. 3. Using compass bearing point the antenna in the direction of the CT (base station) antenna. 4. Select the Radio Data tab to display ST data. For details of the display see STMON Display Descriptions 5. Wait for both an uplink and a downlink to be established. If The ST Fails to acquire check the display to see that the ST has been configured correctly and there is sufficient signal strength and check compass bearing for CT. Check that the antenna does not breach the deployment guidelines. 6. If ST supports voice. Connect a telephone to the ST and make a test call With the call in progress read and record the following from STMON: a) The receiver power in dBm. b) The transmitter power in dBm. c) The downlink SNR 7. Click the Advanced button. Select the Radio Analysis tab. Click the Peak Meter Button (Alt+p) . The peak meter displays the current downlink signal strength and is used when panning an antenna to find the strongest signal.The peak downlink signal strength displays the maximum downlink signal strength measured since the start of monitoring and can be reset using the Reset Peak Level button (alt s).
Commissioning 177 8. Pan the antenna unit through a ± 10° azimuth and note down the bearing to which the Current Downlink Signal Strength is a maximum. This value should be very near to the peak value shown in the Peak Downlink Signal Strength box. 9. Using a 10mm spanner or socket torque the pivot bolts to 12Nm. 10. If the ST is located close to the CT (likely to be less than 1.5km is used as a guideline), the receiving signal from the base station is high (likely to be greater than -50dBm). The loud switch may be used to switch in approximately 30dB of attenuation to simulate an increase the path loss, which will prevent the RX signal strength from saturating the ST receiver (saturation of the ST receiver is exhibited as high errors in the radio link). Optimise SNR 1. To optimise SNR select the 'Radio Data' tab in STMON make a note of the current Uplink and Downlink SNR. 2. Select the 'Radio Analysis' tab and click the 'turn loudswitch on' button to turn on the loudswitch 3. Return to the 'Radio Data' view and observe the change in both the uplink and the downlink SNR. If the SNR has improved then leave the loud switch turned on. If the SNR has deteriorated then return to the 'Radio Analysis' view and turn the loudswitch off. 4. Finally check that the SNR has returned to its previous level. Link Quality / Modulation rate check STMON is able to monitor the following link quality parameters: o Current Downlink Modulation/FEC mode o Receive SNR Margin o Receive Fade Margin o Current Uplink Modulation/FEC mode o Transmitter Fade Margin Each of these parameters are compared with the entered installation acceptance criteria and pass/fail indicators displayed on STMON.
