This document is uncontrolled pending incorporation in PDM 1 OVERVIEW 15 Security The SVG2500 provides the following: • A firewall to protect the SVG2500 LAN from undesired attacks over the Internet • For wireless transmissions, data encryption and network access control Network Address Translation (NAT) provides some security because the IP addresses of SVG2500 LAN computers are not visible on the Internet. This diagram does not necessarily correspond to the network cabling. A full discussion of network security is beyond the scope of this document. Figure 1-6 — SVG2500 Security Measures
This document is uncontrolled pending incorporation in PDM 1 OVERVIEW 16 Firewall The SVG2500 firewall protects the SVG2500 LAN from undesired attacks and other intrusions from the Internet. It provides an advanced, integrated stateful-inspection firewall supporting intrusion detection, session tracking, and denial-of-service attack prevention. The firewall: • Maintains state data for every TCP/IP session on the OSI network and transport layers • Monitors all incoming and outgoing packets, applies the firewall policy to each one, and screens for improper packets and intrusion attempts • Provides comprehensive logging for all: • User authentications • Rejected internal and external connection requests • Session creation and termination • Outside attacks (intrusion detection) You can configure the firewall filters to set rules for port usage. For information about choosing a predefined firewall policy template, see Section 7, SVG2500 Firewall Pages. DMZ A de-militarized zone (DMZ) is one or more computers logically located outside the firewall between an SVG2500 LAN and the Internet. A DMZ prevents direct access by outside users to private data. For example, you can set up a web server on a DMZ computer to enable outside users to access your website without exposing confidential data on your network. A DMZ can also be useful to play interactive games that may have a problem running through a firewall. You can leave a computer used for gaming only exposed to the Internet while protecting the rest of your network. For more information, see Gaming Configuration Guidelines. Port Triggering When you run an application that accesses the Internet, it typically initiates communications with a computer on the Internet. For some applications, especially gaming, the computer on the Internet also initiates communications with your computer. Because NAT does not normally allow these incoming connections: • The SVG2500 has preconfigured port triggers for common applications. • If needed, you can configure additional port triggers on the Advanced Port Triggers Page.
This document is uncontrolled pending incorporation in PDM 1 OVERVIEW 17 Wireless Security Because WLAN data is transmitted using radio signals, it may be possible for an unauthorized person to access your WLAN unless you prevent them from doing so. To prevent unauthorized eavesdropping of data transmitted over your LAN, you must enable wireless security. The default SVG2500 settings neither provide security for transmitted data nor protect network data from unauthorized intrusions. The SVG2500 provides the following wireless security measures, which are described in Section 9, SVG2500 Wireless Pages. To prevent unauthorized eavesdropping, you must encrypt data transmitted over the wireless interface using one of the following: • If all of your wireless clients support Wi-Fi® Protected Access (WPA) encryption, Motorola recommends using WPA. Otherwise, configure a Wired Equivalency Privacy (WEP) key on the SVG2500 and each WLAN client. • To protect LAN data from unauthorized intrusions, you can restrict WLAN access to computers having one or both of: • Known MAC addresses • The same unique network name (SSID) as the SVG2500 Restricting access to computers having the same network name is also called “disabling SSID broadcasting” or “enabling closed network operation.” Port Forwarding The SVG2500 opens logical data ports when a computer on its LAN sends data, such as e-mail messages or web data, to the Internet. A logical data port is different from a physical port, such as an Ethernet port. Data from a protocol must go through certain data ports. Some applications, such as games and videoconferencing, require multiple data ports. If you enable NAT, this can cause problems because NAT assumes that data sent through one port will return to the same port. You may need to configure port forwarding to run applications with special requirements. To configure port forwarding, you must specify an inbound (source) port or range of ports. The inbound port opens only when data is sent to the inbound port and closes again after a specified time elapses with no data sent to it. You can configure up to 32 port forwarding entries using the Advanced Port Forwarding Page. Virtual Private Networks The SVG2500 supports multiple tunnel VPN pass-through operation to securely connect remote computers over the Internet. The SVG2500: • Is compatible with Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP) • Is fully interoperable with any IPSec client or gateway and ANX certified IPSec stacks

This document is uncontrolled pending incorporation in PDM 3 BASIC CONFIGURATION 58 Gaming Configuration Guidelines The following provides information about configuring the SVG2500 firewall and DMZ for gaming. Configuring the Firewall for Gaming By default, the SVG2500 firewall is disabled. If, as recommended, you enable the firewall, refer to the game’s documentation to ensure that the necessary ports are open for use by that game. The pre-defined SVG2500 firewall policies affect Xbox LIVE® as follows: On the Firewall Web Content Filter Page, you may need to disable Firewall Protection and IP Flood Detection. Configuring Port Triggers Because the SVG2500 has pre-defined port triggers for games using any of the following applications, no user action is required to enable them: • DirectX 7 and DirectX 8 • MSN Games by Zone.com • Battle.net® For a list of games supported by Battle.net, visit http://www.battle.net. You may need to create custom port triggers to enable other games to operate properly. To create custom port triggers, use the Advanced Configuring Port Triggers Page. Configuring a Gaming DMZ Host Caution! The gaming DMZ host is not protected by the firewall. It is open to communication or hacking from any computer on the Internet. Consider carefully before configuring a device to be in the DMZ. Some games and game devices require one of: • The use of random ports • The forwarding of unsolicited traffic For example, to connect a PlayStation®2 for PS2® online gaming, designate it as the gaming DMZ host because the ports required vary from game to game. For these games, Motorola recommends configuring the gaming computer or device as a gaming DMZ device. To configure a gaming DMZ device, on the Basic DHCP Page: 1. Reserve a private IP address for the computer or game device MAC address. 2. Designate the device as a DMZ device.
This document is uncontrolled pending incorporation in PDM 3 BASIC CONFIGURATION 59 You can reserve IP addresses for multiple devices, but only one can be designated as the gaming DMZ at once.

This document is uncontrolled pending incorporation in PDM 6 SVG2500 ADVANCED PAGES 75 Advanced IP Filtering Page This page allows you to define which local PCs will be denied access to the SVG2500 WAN. You can configure IP address filters to block Internet traffic to specific network devices on the LAN by entering starting and ending IP address ranges. Note that you only need to enter the LSB (Least-significant byte) of the IP address; the upper bytes of the IP address are set automatically from the SVG2500 Configuration Manager’s IP address. The Enabled option allows you to store filter settings commonly used but not have them active. Field Description Start Address Enter the starting IP address range of the computers for which you want to deny access to the SVG2500 WAN. Be sure to only enter the least significant byte of the IP address. End Address Enter the ending IP address range of the computers you want to deny access to the SVG2500 WAN. Be sure to only enter the least significant byte of the IP address. Enabled Activates the IP address filter, when selected. Checkmark Enabled for each range of IP addresses you want to deny access to the SVG2500 WAN. When done, click Apply to activate and save your settings.
This document is uncontrolled pending incorporation in PDM 6 SVG2500 ADVANCED PAGES 76 Advanced MAC Filtering Page This page allows you to define Media Access Control (MAC) address filters to prevent PCs from sending outgoing TCP/UDP traffic to the WAN via their MAC addresses. This is useful because the MAC address of a specific NIC card never changes, unlike its IP address, which can be assigned via the DHCP server or hard-coded to various addresses over time. Field Description MAC nn Media Access Control address — a unique set of 12 hexadecimal digits assigned to a PC during manufacturing Setting a MAC Address Filter 1. Enter the MAC address in the MAC nn field for each PC you want to block. 2. When done, click Apply.
This document is uncontrolled pending incorporation in PDM 6 SVG2500 ADVANCED PAGES 77 Advanced Port Filtering Page This page allows you to define port filters to prevent all devices from sending outgoing TCP/UDP traffic to the WAN on specific IP port numbers. By specifying a starting and ending port range, you can determine what TCP/UDP traffic is allowed out to the WAN on a per-port basis. Note: The specified port ranges are blocked for ALL PCs, and this setting is not IP address or MAC address specific. For example, if you wanted to block all PCs on the private LAN from accessing HTTP sites (or "web surfing"), you would set the "Start Port" to 80, "End Port" to 80, "Protocol" to TCP, checkmark Enabled, and then click Apply. Field Description Start Port Enter the starting port number. End Port Enter the ending port number. Protocol Select TCP, UDP, or Both Enabled Checkmark for each port that you want to activate the IP port filters.
This document is uncontrolled pending incorporation in PDM 6 SVG2500 ADVANCED PAGES 78 Advanced Port Forwarding Page This page allows you to run a publicly accessible server on the LAN by specifying the mapping of TCP/UDP ports to a local PC. This enables incoming requests on specific port numbers to reach web servers, FTP servers, mail servers, etc. so that they can be accessible from the public Internet. A table of commonly used Port numbers is also displayed on the page for your convenience. To map a port, you must enter the range of port numbers that should be forwarded locally and the IP address to which traffic to those ports should be sent. If only a single port specification is desired, enter the same port number in the "start" and "end" locations for that IP address. The ports used by some common applications are: • FTP: 20, 21 • HTTP: 80 • NTP: 123 • Secure Shell: 22 • SMTP e-mail: 25 • Telnet: 23
This document is uncontrolled pending incorporation in PDM 6 SVG2500 ADVANCED PAGES 79 Advanced Port Triggers Page This page allows you to configure dynamic triggers to specific devices on the LAN. This allows for special applications that require specific port numbers with bi-directional traffic to function properly. Applications such as video conferencing, voice, gaming, and some messaging program features may require these special settings. The Advanced Port Triggers are similar to Port Forwarding except that they are not static ports held open all the time. When the Configuration Manager detects outgoing data on a specific IP port number set in the "Trigger Range," the resulting ports set in the "Target Range" are opened for incoming (sometimes referred to as bi-directional ports) data. If no outgoing traffic is detected on the "Trigger Range" ports for 10 minutes, the "Target Range" ports will close. This is a safer method for opening specific ports for special applications (e.g. video conferencing programs, interactive gaming, file transfer in chat programs, etc.) because they are dynamically triggered and not held open constantly or erroneously left open via the router administrator and exposed for potential hackers to discover. Field Description Trigger Range Start Port The starting port number of the Port Trigger range. End Port The ending port number of the Port Trigger range. Target Range Start Port The starting port number of the Port Trigger range. End Port The ending port number of the Port Trigger range. Protocol Choice of TCP or UDP, or Both Enable Select checkbox to activate the IP port triggers.
This document is uncontrolled pending incorporation in PDM 6 SVG2500 ADVANCED PAGES 80 Advanced DMZ Host Page This page allows you to specify the "default" recipient of WAN traffic that NAT is unable to translate to a known local PC. The DMZ (De-militarized Zone) hosting (also commonly referred to as "Exposed Host") can also be described as a computer or small sub-network that sits between the trusted internal private LAN and the untrusted public Internet. You may configure one PC to be the DMZ host. This setting is generally used for PCs using "problem" applications that use random port numbers and do not function correctly with specific port triggers or the port forwarding setups mentioned earlier. If a specific PC is set as a DMZ Host, remember to set this back to "0" when you are finished with the needed application, since this PC will be effectively exposed to the public Internet, though still protected from Denial of Service (DoS) attacks via the Firewall. Setting Up the DMZ Host 1. Enter the computer’s IP address. 2. Click Apply to activate the selected computer as the DMZ host.
This document is uncontrolled pending incorporation in PDM 6 SVG2500 ADVANCED PAGES 81 Advanced Routing Information Protocol Setup Page This page allows you to configure Routing Information Protocol (RIP) parameters related to authentication, destination IP address/subnet mask, and reporting intervals. RIP automatically identifies and uses the best known and quickest route to any given destination address. To help reduce network congestion and delays, the Advanced RIP setup is used in WAN networks to identify and use the best known and quickest route to given destination addresses. RIP is a protocol that requires negotiation from both sides of the network (i.e., CMRG and CMTS). The ISP would normally set this up to match their CMTS settings with the configuration in the CMRG. Note: RIP messaging will only be sent upstream when running in Static IP Addressing mode on the Basic - Setup page. You must enable Static IP Addressing and then set the WAN IP network information! RIP is normally a function that is tightly controlled via the ISP. RIP Authentication Keys and IDs are normally held as secret information from the end user to prevent unauthorized RIP settings. Field Description RIP Enable Enables or disables the RIP protocol. This protocol helps the router dynamically adapt to the changes in the network. RIP is now considered obsolete since newer routing protocols, such as OSPF and ISIS, have been introduced. RIP Authentication If this field is enabled, a plain text password or a shared key authentication is added to the RIP packet in order for the CPE and the wireless router to authenticate each other. RIP Authentication Key Used to encrypt the plain text password that is enclosed in each RIP packet. If you are using the shared key authentication in RIP, you will need to provide a key. RIP Authentication Key ID An unsigned 8-bit field in the RIP packet. This field identifies the key used to create the authentication data for the RIP packet, and it also indicates the authentication algorithm.
This document is uncontrolled pending incorporation in PDM 6 SVG2500 ADVANCED PAGES 82 Field Description RIP Reporting Interval Determines how long before a RIP packet is sent out to the CPE. RIP Destination IP Address Location where the RIP packet is sent to update the routing table in your CPE. RIP Destination IP Subnet Mask Specifies which CPE you want to receive the RIP packet.
This document is uncontrolled pending incorporation in PDM 83 7 SVG2500 FIREWALL PAGES The SVG2500 Firewall Pages allow you to configure the SVG2500 firewall filters and firewall alert notifications. You can click any Firewall submenu option to view or change the firewall configuration information for that option. For information about how the firewall can affect gaming, see Gaming Configuration Guidelines. The predefined policies provide outbound Internet access for computers on the SVG2500 LAN. The SVG2500 firewall uses stateful inspection to allow inbound responses when there already is an outbound session running corresponding to the data flow. For example, if you use a web browser, outbound HTTP connections are permitted on port 80. Inbound responses from the Internet are allowed because an outbound session is established. When required, you can configure the SVG2500 firewall to allow inbound packets without first establishing an outbound session. You also need to configure a port forwarding entry on the Advanced Port Forwarding Page or a DMZ client on the Advanced DMZ Host Page.
This document is uncontrolled pending incorporation in PDM 7 SVG2500 FIREWALL PAGES 84 Firewall Web Content Filter Page This page allows you to configure the firewall by enabling or disabling various Web filters related to blocking or exclusively allowing different types of data through the Configuration Manager from the WAN to the LAN. Java Applets, Cookies, ActiveX controls, popup windows, and Proxies can be blocked from this page. Firewall Protection turns on the Stateful Packet Inspection (SPI) firewall features. Block Fragmented IP packets prevent all fragmented IP packets from passing through the firewall. Port Scan Detection detects and blocks port scan activity originating on both the LAN and WAN. IP Flood Detection detects and blocks packet floods originating on both the LAN and WAN. Checkmark Enable for each Web filter you want to set for the firewall, and then click Apply. The Web filters will activate without having to reboot the SVG2500 Configuration Manager. Note: If you deselect all the Web filters, you will disable the firewall. This is not recommended.

This document is uncontrolled pending incorporation in PDM 93 9 SVG2500 WIRELESS PAGES The SVG2500 Wireless Pages allow you to configure your wireless LAN (WLAN). You can click any Wireless submenu option to view or change the configuration information for that option. WPA encryption provides higher security than WEP encryption, but older wireless client cards may not support the newer WPA encryption methods. Setting Up Your Wireless LAN You can use the SVG2500 as an access point for a wireless LAN (WLAN) without changing its default settings. Caution! To prevent unauthorized eavesdropping or access to WLAN data, you must enable wireless security. The default SVG2500 settings provide no wireless security. After your WLAN is operational, be sure to enable wireless security. To enable security for your WLAN, you can do the following on the SVG2500: To Perform Use in SVG2500 Configuration Mgr Encrypt wireless transmissions and restrict WLAN access Encrypting Wireless LAN Transmissions Wireless 802.11b/g Privacy Page Further prevent unauthorized WLAN intrusions Restricting Wireless LAN Access Wireless 802.11b/g Access Control Page Caution! Never provide your SSID, WPA or WEP passphrase, or WEP key to anyone who is not authorized to use your WLAN. Connect at least one computer to the SVG2500 Ethernet or USB port to perform configuration. Do not attempt to configure the SVG2500 over a wireless connection. You need to configure each wireless client (station) to access the SVG2500 LAN as described in Configuring the Wireless Clients. Another step to improve wireless security is to place wireless components away from windows. This decreases the signal strength outside the intended area.
This document is uncontrolled pending incorporation in PDM 9 SVG2500 WIRELESS PAGES 94 Encrypting Wireless LAN Transmissions To prevent unauthorized viewing of data transmitted over your WLAN, you must encrypt your wireless transmissions. Use the Wireless 802.11b/g Privacy Page to encrypt your transmitted data. Choose one of: Configure on the SVG2500 Required on Each Wireless Client If all of your wireless clients support Wi-Fi Protected Access (WPA), Motorola recommends configuring WPA on the SVG2500 If you use a local pre-shared key (WPA-PSK) passphrase, you must configure the identical passphrase to the SVG2500 on each wireless client. Home and small-office settings typically use a local passphrase. Otherwise, configure WEP on the SVG2500 You must configure the identical WEP key to the SVG2500 on each wireless client. If all of your wireless clients support WPA encryption, Motorola recommends using WPA instead of WEP because WPA: • Provides much stronger encryption and is more secure • Provides authentication to ensure that only authorized users can log in to your WLAN • Is much easier to configure • Uses a standard algorithm on all compliant products to generate a key from a textual passphrase • Will be incorporated into the new IEEE 802.11i wireless networking standard For new wireless LANs, Motorola recommends purchasing client adapters that support WPA encryption.
This document is uncontrolled pending incorporation in PDM 9 SVG2500 WIRELESS PAGES 95 Wireless 802.11b/g Basic Page This page allows you to configure the Access Point parameters including the SSID and channel number. Creating a SecureEasySetup™ (SES) network ensures strong security for preventing unauthorized wireless network access. However, traditional wireless network installation can be a complicated and time-consuming task, requiring the user to possess the technical know-how to manually enter several settings (such as network name, and encryption key or WPA pass phrase) on each Wi-Fi device. Motorola SecureEasySetup technology dramatically simplifies installation by automating the processes of configuring new wireless networks and adding devices to existing networks. SecureEasySetup establishes a private connection between the devices and automatically configures the network's Service Set Identifier (SSID) and WPA-Personal security settings. It configures a new network only on each new device that is authorized to join the network. Field Description Wireless MAC Address Shows the MAC address of the installed wireless card. It is not configurable. Network Name (SSID) Sets the Network Name (also known as SSID) of the wireless network. This is a 1-32 ASCII character string.
This document is uncontrolled pending incorporation in PDM 9 SVG2500 WIRELESS PAGES 96 Field Description Network Type Selecting Closed prevents the network name from appearing in a wireless client’s "Available Wireless Networks" list. Only clients who already know the network name will be able to connect. Closed disables the SSID broadcast in beacon packets. Selecting Open allows broadcasting to the SSID in beacon packets. Country Restricts the channel set based on the country's regulatory requirements. This is a display-only field. Channel Selects the channel for access point (AP) operation. The list of available channels depends on the designated country. For this field, the channel selected on the wireless clients on your WLAN must be the same as the one selected on the SVG2500. Interface Allows the access point to be Enabled or Disabled. Create SES Network This action button generates a new SecureEasySetup network, applies the configuration to the wireless interface, and stores the settings to non-volatile memory. It enables WPA-PSK authentication and generates a unique Network Name (SSID) and random, 16-character Pre-Shared Key (PSK). The pop-up window shown informs the user a SecureEasySetup network has been successfully created. Open SES Window This action button opens a 2-minute security window that allows a SecureEasySetup client to connect. Only 1 SecureEasySetup client may connect during an Open Window period. If you have more than 1 client to connect to your SecureEasySetup, you must open the window multiple times. When the SecureEasySetup window is open, the pop-up window below indicates the CMRG is waiting for a SecureEasySetup client.

This document is uncontrolled pending incorporation in PDM 9 SVG2500 WIRELESS PAGES 98 Field Description WPA WPA2 Enables or disables Wi-Fi Protected Access (WPA) encryption. WPA-PSK WPA2-PSK Enables or disables a local pre-shared key (WPA-PSK) passphrase. WPA/WPA2 Encryption When using WPA or WPA-PSK authentication, these WPA encryption modes can be set: TKIP, AES, or TKIP + AES. AES (Advanced Encryption Standard) provides the strongest encryption, while TKIP (Temporal Key Integrity Protocol) provides strong encryption with improved compatibility. The TKIP + AES mode allows both TKIP and AES-capable clients to connect. WPA Pre-Shared Key Sets the WPA Pre-Shared Key (PSK). This is an 8-63 ASCII character string, or a 64-digit hex number. Enabled when the Network Authentication method is WPA-PSK. RADIUS Server Sets the RADIUS server IP address to use for client authentication using the dotted-decimal format (xxx.xxx.xxx.xxx). RADIUS Port Sets the UDP port number of the RADIUS server. The default is 1812. RADIUS Key Sets the shared secret for the RADIUS connection. The key is a 0 to 255 character ASCII string. Group Key Rotation Interval Sets the WPA Group Rekey Interval in seconds. Set to zero to disable periodic rekeying. WPA/WPA2 Re-auth Interval WPA and WPA2 are two security features in WiFi technology. This field, re-authentication interval, is the amount of time the wireless router can wait before re-establishing authentication with the CPE. WEP Encryption Enables or disables Wired Equivalent Privacy encryption. Shared Key Authentication The WEP protocol uses Shared Key Authentication, which is an Authentication protocol where the CPE sends an authentication request to the access point. Then the access point sends a challenge text to the CPE. The CPE uses either the 64-bit or 128-bit key to encrypt the challenge text, and sends the encrypted text to the access point. The access point will decrypt the encrypted text and then compare the decrypted message with the original challenge text. If they are the same the access point it will let the CPE connect; if it doesn’t match then the access point does not let the CPE connect. 802.1x Authentication This is another type of authentication and is used on top of WEP. 802.1x Authentication is a much stronger type of authentication than WEP.
This document is uncontrolled pending incorporation in PDM 9 SVG2500 WIRELESS PAGES 99 Field Description Network Key 1-4 Sets the static WEP keys when WEP encryption is enabled. Enter 5 ASCII characters or 10 hexadecimal digits for a 64-bit key. Enter 13 ASCII characters or 26 hexadecimal digits for a 128-bit key. When both WPA encryption and WEP encryption are enabled, only keys 2 and 3 are available for WEP encryption. Current Network Key When WEP encryption is enabled, selects the encryption (transmit) key. PassPhrase Sets the text to use for WEP key generation. WPS Config Allows the WiFi Protected Setup to be enabled or disabled. Button Mode Allows the type of setup for the Wireless Security: • SES — Secure Easy Setup • WPS — WiFi Protected Setup Device Name Name of the WPS device STA PIN The station PIN method where it is entered as the "representant" of the Network that follows the WPS protocol architecture.

This document is uncontrolled pending incorporation in PDM 10 SVG2500 VPN PAGES 113 Field Description IPsec Settings With VPN tunnels, there are two phases of Security Association (SA). Phase 1 is used to create an IKE SA. After Phase 1 is completed, Phase 2 is used to create one or more IPSEC SAs, which are then used to key IPSEC sessions. Pre-shared key If one side of the VPN tunnel is using a unique firewall identifier (or Pre-shared Key), the firewall identifier or Pre-shared Key should be entered in the "Pre-shared Key" field. Phase 1 DH group There are three Diffie-Hellman groups to choose from: 768 bits, 1024 bits, and 1536 bits. Diffie-Hellman is a cryptographic technique that uses public and private keys for encryption and decryption. The higher number of bits selected from the options list the more secure the encryption. Options: Group 1 (768 bits), Group 2 (1024 bits), or Group 5 (1536 bits). Phase 1 encryption Encryption is used to secure the VPN connection between endpoints. Five different types of encryption are available: DES, 3DES, AES-128, AES-192, and AES-256. Any form off encryption may be selected as long as the far endpoint matches. One of the more common settings here is 3DES; however, AES is also a very strong encryption method. Phase 1 authentication Authentication acts as another level of security. The two types of authentication available are MD5 and SHA. SHA is recommended because it is more secure. Either authentication type may be used as long as the other end of the VPN tunnel uses the same method. Phase 1 SA lifetime Specifies the lifetime of individual rotating keys. Enter the desired number of seconds for the key to last until a re-key negotiation between each endpoint is negotiated. The default setting is 28,800 seconds. A smaller lifetime is generally more secure, since it would give an attacker a smaller amount of time to try to crack the key, but key negotiation does take up bandwidth, so network throughput will be sacrificed with small lifetimes. Entries here are typically in the thousands or tens of thousands of seconds.

Class C IP addresses are in the form “network.network. network. host.” client In a client/server architecture, a client is a computer that requests files or services, such as file transfer, remote login, or printing from the server. Also called a CPE. On a WLAN, a client is any host that can communicate with the access point. A wireless client is also called a “station.” CMTS A cable modem termination system is a device in the cable system headend that interfaces the HFC network to local or remote IP networks to connecting IP hosts, cable modems or gateways, and subscribers. It manages all cable modem bandwidth. It is sometimes called an edge router CNR carrier to noise ratio coaxial cable A type of cable consisting of a center wire surrounded by insulation and a grounded shield of braided (coax) wire. The shield minimizes electrical and radio frequency interference. Coaxial cable has high bandwidth and can support transmission over long distances. CoS Class of service traffic management or scheduling functions are performed when transferring data upstream or downstream on HFC. CPE Customer premise equipment, typically computers, printers, etc., are connected to the cable modem or gateway at the subscriber location. CPE can be provided by the subscriber or the Internet Service provider. Also called a client. crosstalk Undesired signal interfering with the desired signal. CSMA/CD Carrier sense multiple access with collision detection D TERM DEFINITION datagram In RFC 1594, a datagram is defined as “a self-contained, independent entity of data carrying sufficient information to be routed from the source to the destination computer without reliance on earlier exchanges between this source and destination computer and the transporting network.” For the most part, it has been replaced by the term packet.
This document is uncontrolled pending incorporation in PDM 17 GLOSSARY 141 TERM DEFINITION default route The route by which packets are forwarded when other routes in the routing table do not apply. dB decibel dBc Signal level expressed in dB relative to the unmodulated carrier level desired. DBm A unit of measurement referenced to one milliwatt across specified impedance. 0dBm = 1 milliwatt across 75 ohms. dBmV Signal level expressed in dB as the ratio of the signal power in a 75-ohm system to a reference power when 1 mV is across 75 ohms. demodulation An operation to restore a previously modulated wave and separate the multiple signals that were combined and modulated on a sub carrier. DHCP A Dynamic Host Configuration Protocol server dynamically assigns IP addresses to client hosts on an IP network. DHCP eliminates the need to manually assign static IP addresses by “leasing” an IP address and subnet mask to each client. It enables the automatic reuse of unused IP addresses. The SVG2500 is simultaneously a DHCP client and a DHCP server. A DHCP server at the cable system headend assigns a public IP address to the SVG2500 and optionally to clients on the SVG2500 LAN. The SVG2500 contains a built-in DHCP server that assigns private IP addresses to clients. distortion An undesired change in signal waveform within a transmission medium. A nonlinear reproduction of the input waveform. DMZ A “de-militarized zone” is one or more hosts logically located between a private LAN and the Internet. A DMZ prevents direct access by outside users to private data. (The term comes from the geographic buffers located between some conflicting countries, such as North and South Korea.) In a typical small DMZ configuration, the DMZ host receives requests from private LAN users to access external web sites and initiates sessions for these requests. The DMZ host cannot initiate a session back to the private LAN. Internet users outside the private LAN can access only the DMZ host. You can use a DMZ to set up a web server or for gaming without exposing confidential data.

When you access the world-wide web, a DNS server translates the URL displayed on the browser to the destination website IP address. The DNS lookup table is a distributed Internet database; no one DNS server lists all domain names to IP address matches. DOCSIS The CableLabs Data-Over-Cable Service Interface Specification defines interface standards for cable modems, gateways, and supporting equipment to deliver data between an HFC network and computer systems or television sets. To emphasize its use as a cable modem standard, DOCSIS is now called CableLabs Certified Cable Modems. Euro-DOCSIS is DOCSIS adapted for use in Europe. domain name A unique name, such as motorola.com, that maps to an IP address. Domain names are typically much easier to remember than are IP addresses. dotted-decimal format Method of representing an IP address or subnet mask using four decimal numbers called octets. Each octet represents eight bits. In a class C IP address, the octets are “network.network.network.host.” The first three octets together represent the network address and the final octet is the host address. In the SVG2500 LAN default configuration, 192.168.100 represents the network address. In the final octet, the host address can range from 2 to 254. download To copy a file from one computer to another. You can use the Internet to download files from a server to a computer. A DOCSIS or Euro-DOCSIS cable modem or gateway downloads its configuration file from a TFTP server during start-up. downstream In a cable data network, the direction of data received by the computer from the Internet. driver Software that enables a computer to interact with a network or other device.

Ingress is the major source of cable system noise. Internet A worldwide collection of interconnected networks using TCP/IP. Internetwork A collection of interconnected networks allowing communication between all devices connected to any network in the collection. IP Internet Protocol is a set of standards that enable different types of computers to communicate with one another and exchange data through the Internet. IP provides the appearance of a single, seamless communication system and makes the Internet a virtual network. IP address A unique 32-bit value that identifies each host on a TCP/IP network. TCP/IP networks route messages based on the destination IP address. An IP address has two parts: • A network address assigned by IANA • SVG2500 network administrator assigns a host address to each host connected to the SVG2500, automatically using its DHCP server as a static IP address. For a Class C network, the first 24 bits are the network address and the final 8 bits are the host address; in dotted-decimal format, the IP address appears as “network.network.network.host.” If you enable the SVG2500 DHCP client on the Basic DHCP Page, the Internet Service provider automatically assigns the network address, subnet mask, domain name, and DNS server to provide a continuous Internet connection. IPSec The Internet Protocol Security protocols are IETF authentication and encryption standards for secure packet exchange over the Internet. IPSec works at OSI layer 3 and secures everything on the network. IKE Internet Key Exchange

ISP Internet Service Provider ITU International Telecommunications Union K TERM DEFINITION kHz kilohertz — one thousand cycles per second L TERM DEFINITION L2F Layer 2 Forwarding is an OSI layer 2 protocol that establishes a secure tunnel across the Internet to create a virtual PPP connection between the user and the enterprise network. L2F is the most established and stable layer 2 tunneling protocol. L2TP Layer 2 Tunnel Protocol is a PPP extension that enables ISPs to operate VPNs. L2TP merges the best features of the PPTP and L2F. L2TP is the emerging IETF standard. LAC An L2TP access concentrator is a device to which the client directly connects through which PPP frames are tunneled to the LNS. The LAC need only implement the media over which L2TP operates to transmit traffic to one or more LNSs. The LAC may tunnel any protocol carried within PPP. The LAC initiates incoming calls and receives outgoing calls. A LAC is analogous to an L2F NAS. LAN A local area network provides a full-time, high-bandwidth connection over a limited area, such as a building or campus. Ethernet is the most widely used LAN standard. layer In networks, layers are software protocol levels. Each layer performs functions for the layers above it. OSI is a reference model having seven functional layers.

Q TERM DEFINITION QAM Quadrature Amplitude Modulation uses amplitude and phase modulation to encode multiple bits of data in one signaling element. QAM achieves faster data transfer than amplitude or phase modulation alone, but the signal is more prone to errors caused by noise. QAM requires a transmission circuit with a higher CNR than alternate modulation formats such as QPSK. Two types of QAM are: • 16 QAM, which encodes four bits per symbol as one of 16 possible amplitude and phase combinations. • 64 QAM, which encodes six bits per symbol as one of 64 possible amplitude and phase combinations. QPSK Quadrature Phase Shift Keying is a phase modulation algorithm. Phase modulation is a version of frequency modulation where the phase of the carrier wave is modulated to encode bits of digital information in each phase change. QoS Quality of service describes the priority, delay, throughput, and bandwidth of a connection. R TERM DEFINITION RAS Remote Access Server registration How a cable modem makes itself known to the CMTS.
