Wireless LAN Wireless communication occurs over radio waves rather than a wire. Like a cordless telephone, a WLAN uses radio signals instead of wires to exchange data. A wireless network eliminates the need for expensive and intrusive wiring to connect computers throughout the home or office. Mobile users can remain connected to the network even when carrying their laptop to different locations in the home or office. Each computer on a WLAN requires a wireless adapter. Laptop PCs — Use a wireless notebook adapter in the PCMCIA slot or a wireless USB adapter. Desktop PCs — Use a wireless PCI adapter, wireless USB adapter, or compatible product in the PCI slot or USB port, respectively. Figure 5 Sample Wireless Network Connections To set up the SBG901 on a computer wired to the SBG901 with an Ethernet connection, perform the procedures found on the Wireless Pages. Do not attempt to configure the SBG901 over a wireless connection. Your maximum wireless operation distance depends on the type of materials through which the signal must pass and the location of your SBG901 and clients (stations). Motorola cannot guarantee wireless operation for all supported distances in all environments. 1 Introduction 19 This document is uncontrolled pending incorporation in PDM
Wired Ethernet LAN You can easily connect any PC with an Ethernet LAN port to the SBG901 Ethernet connection. Because the SBG901 Ethernet port supports auto-MDIX, you can use straight-through or cross-over cable to connect a hub, switch, or computer. Use category 5, or better, cabling for all Ethernet connections. Figure 6 Sample Ethernet to Computer Connection The physical wiring arrangement has no connection to the logical network allocation of IP addresses. A wired Ethernet LAN with more than one computer requires one or more hubs, switches, or routers. You can do the following: • Connect a hub or switch to the Ethernet port on the SBG901 • Use Ethernet hubs, switches, or routers to connect up to 245 computers to the SBG901 A complete discussion of Ethernet cabling is beyond the scope of this document. Security The SBG901 provides the following: • A firewall to protect the SBG901 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 SBG901 LAN computers are not visible on the Internet. 1 Introduction 20 This document is uncontrolled pending incorporation in PDM
Firewall The SBG901 firewall protects the SBG901 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 the Firewall Pages. DMZ A de-militarized zone (DMZ) is one or more computers logically located outside the firewall between an SBG901 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: • If needed, you can configure additional port triggers on the Advanced Port Triggers Page. 1 Introduction 21 This document is uncontrolled pending incorporation in PDM
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 SBG901 settings neither provide security for transmitted data nor protect network data from unauthorized intrusions. The SBG901 provides the following wireless security measures, which are described on the 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 or WPA2) encryption, Motorola recommends using WPA2. Otherwise, configure a Wired Equivalency Privacy (WEP) key on the SBG901 and each WLAN client. • To protect the wireless LAN from unauthorized intrusions (see Setting Up Your Wireless LAN), you can do one or both of the following:  Restrict WLAN access to computers having known MAC addresses  Enable closed network operation by disabling SSID broadcasting Port Forwarding The SBG901 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 video conferencing, 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. 1 Introduction 22 This document is uncontrolled pending incorporation in PDM

Gaming Configuration Guidelines The following provides information about configuring the SBG901 firewall and DMZ for gaming. Configuring the Firewall for Gaming By default, the SBG901 firewall is enabled. If, as recommended, you keep the firewall enabled, refer to the game’s documentation to ensure that the necessary ports are open for use by that game. The pre-defined SBG901 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. 3 Basic Configuration 44 This document is uncontrolled pending incorporation in PDM
Configuring Port Triggers Because the SBG901 has pre-defined port triggers for games using any of the following applications, no user action is required to enable them: • ALG for MSN • MSN Games by Zone.com You may need to create custom port triggers to enable other games to operate properly. To create custom port triggers, see the Advanced 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. You can reserve IP addresses for multiple devices, but only one can be designated as the gaming DMZ at once.

Advanced IP Filtering Page This page allows you to define which local PCs will be denied access to the SBG901 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 SBG901 Configuration Manager’s IP address. The Enabled option allows you to store filter settings commonly used but not have them active. Figure 38 Advanced IP Filtering Page Table 13 Field Descriptions for the Advanced IP Filtering Page Field Description Start Address Enter the starting IP address range of the computers for which you want to deny access to the SBG901 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 SBG901 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 SBG901 WAN. When done, click Apply to activate and save your settings. 6 Advanced Pages 61 This document is uncontrolled pending incorporation in PDM
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. Figure 39 Advanced MAC Filtering Page Table 14 Field Descriptions for the Advanced MAC Filtering Page Field Description MAC xx 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 xx field for each PC you want to block. 2. When done, click Apply. 6 Advanced Pages 62 This document is uncontrolled pending incorporation in PDM
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. Figure 40 Advanced Port Filtering Page Table 15 Field Descriptions for the Advanced Port Filtering Page 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. 6 Advanced Pages 63 This document is uncontrolled pending incorporation in PDM
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. Figure 41 Advanced Port Forwarding Page 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 6 Advanced Pages 64 This document is uncontrolled pending incorporation in PDM
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. Figure 42 Advanced Port Triggers Page Table 16 Field Descriptions for the Advanced Port Triggers Page 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. 6 Advanced Pages 65 This document is uncontrolled pending incorporation in PDM

End Port The ending port number of the Port Trigger range. Protocol Choice, TCP, UDP, or Both Enable Select checkbox to activate the IP port triggers. 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. Figure 43 Advanced DMZ Host Page 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.
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. Figure 44 Advanced RIP Setup Page 6 Advanced Pages 67 This document is uncontrolled pending incorporation in PDM
Table 17 Field Descriptions for the Advanced RIP Setup Page 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. 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. 6 Advanced Pages 68 This document is uncontrolled pending incorporation in PDM
7 Firewall PagesThe SBG901 Firewall Pages allow you to configure the SBG901 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 SBG901 LAN. The SBG901 firewall uses stateful-inspection to allow inbound responses when there already is an outbound session running that corresponds 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 SBG901 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. 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. 7 Firewall Pages 69 This document is uncontrolled pending incorporation in PDM

Firewall Remote Log Page This page allows you to send firewall attack reports out to a standard SysLog server so many instances can be logged over a long period of time. You can select individual attack or configuration items to send to the SysLog server so that only the items of interest will be monitored. You can log permitted connections, blocked connections, known Internet attack types, and CMRG configuration events. The SysLog server must be on the same network as the Private LAN behind the Configuration Manager (typically 192.168.0.x). To activate the SysLog monitoring feature, check all desired event types to monitor and enter the last byte of the IP address of the SysLog server. Normally, the IP address of this SysLog server would be hard-coded so that the address does not change and always agrees with the entry on this page. Figure 47 Firewall Remote Log Page Table 19 Field Description for the Firewall Remote Log Page Field Description Permitted Connections Check for the server to e-mail you logs of who is connecting to your network. Blocked Connections Check for the server to e-mail you logs of who is blocked from connecting to your network.

9 Wireless PagesThe SBG901 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 or WPA2 encryption provides higher security than WEP encryption, but older wireless client cards may not support the newer WPA or WPA2 encryption methods. Setting Up Your Wireless LAN You can use the SBG901 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 SBG901 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 SBG901: Table 21 Enabling Wireless Security on Your LAN To Perform Use in SBG901 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 SBG901 Ethernet port to perform configuration. Do not attempt to configure the SBG901 over a wireless connection. You need to configure each wireless client (station) to access the SBG901 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. 9 Wireless Pages 79 This document is uncontrolled pending incorporation in PDM
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: Table 22 Encrypting Wireless LAN Transmissions Configure on the SBG901 Required on Each Wireless Client If all of your wireless clients support Wi-Fi Protected Access (WPA), Motorola recommends configuring WPA on the SBG901 If you use a local pre-shared key (WPA-PSK) passphrase, you must configure the identical passphrase to the SBG901 on each wireless client. Home and small-office settings typically use a local passphrase. Otherwise, configure WEP on the SBG901 You must configure the identical WEP key to the SBG901 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. 9 Wireless Pages 80 This document is uncontrolled pending incorporation in PDM
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 configuring new wireless networks processes 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. Figure 52 Wireless 802.11b/g Basic Page Table 23 Field Descriptions for the Wireless 802.11b/g Basic Page 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. 9 Wireless Pages 81 This document is uncontrolled pending incorporation in PDM
9 Wireless Pages 82 This document is uncontrolled pending incorporation in PDM 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 SBG901. 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.

9 Wireless Pages 85 This document is uncontrolled pending incorporation in PDM Field Description 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 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. 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 Selects the encryption (transmit) key when WEP encryption is enabled. PassPhrase Sets the text to use for WEP key generation. WPS Config Allows the Wi-Fi Protected Setup to be enabled or disabled. Button Mode Allows the type of setup for the Wireless Security: SES — Secure Easy Setup WPS — Wi-Fi Protected Setup Device Name Name of the WPS device STA PIN The station PIN method, entered as the "representative" of the Network that follows the WPS protocol architecture.

Table 34 Glossary TERM DEFINITION A access point A device that provides WLAN connectivity to wireless clients (stations). The SBG901 acts as a wireless access point. adapter A device or card that connects a computer, printer, or other peripheral device to the network or to some other device. A wireless adapter connects a computer to the WLAN. address See NAT translation. ALG Some file transfer (for example, FTP), game, and video conferencing applications require application-level gateway triggers to open one or more ports to enable the application to operate properly. American Wire Gauge (AWG) A standard system used to designate the size of electrical conductors; gauge numbers are inverse to Gauge (AWG) size. ANX Automotive Network Exchange ARP Address Resolution Protocol broadcasts a datagram to obtain a response containing a MAC address corresponding to the host IP address. When it is first connected to the network, a client sends an ARP message. The SBG901 responds with a message containing its MAC address. Subsequently, data sent by the computer uses the SBG901 MAC address as its destination. ASCII The American Standard Code for Information Interchange refers to alphanumeric data for processing and communication compatibility among various devices; normally used for asynchronous transmission. attenuation The difference between transmitted and received power resulting from loss through equipment, transmission lines, or other devices; usually expressed in decibels. B Glossary 105 This document is uncontrolled pending incorporation in PDM
B Glossary 106 This document is uncontrolled pending incorporation in PDM TERM DEFINITION Authentication A process where the CMTS verifies that access is authorized, using a password, trusted IP address, or serial number. Authorization Part of the process between a CMTS and the cable modem or gateway to enable Baseline Privacy. auto-MDIX Automatic medium-dependent interface crossover detects and corrects cabling errors by automatically reversing the send and receive pins on any port. It enables the use of straight-through wiring between the SBG901 Ethernet port and any computer, printer, or hub B bandwidth The transmission capacity of a medium in terms of a range of frequencies. Greater bandwidth indicates the ability to transmit more data over a given period of time. Baseline Privacy An optional feature that encrypts data between the CMTS and the cable modem or gateway. Protection of service is provided by ensuring that a cable modem or gateway, uniquely identified by its MAC address, can only obtain keys for services it is authorized to access. Baud The analog signaling rate. For complex modulation modes, the digital bit rate is encoded in multiple bits per baud. For example, 64 QAM encodes 6 bits per baud, and 16 QAM encodes 4 bits per baud. BER The bit error rate is the ratio of the number of erroneous bits or characters received from some fixed number of bits transmitted. binary A numbering system that uses two digits, 0 and 1. bit rate The number of bits (digital 0s and 1s) transmitted per second in a communications channel.

The encryption occurs after the cable modem or gateway registers to ensure data privacy across the RF network. bps Bits per second
B Glossary 107 This document is uncontrolled pending incorporation in PDM TERM DEFINITION bridge An OSI layer 2 networking device that connects two LANs using similar protocols. It filters frames based on the MAC address to reduce the amount of traffic. A bridge can be placed between two groups of hosts that communicate a lot together, but not so much with the hosts in the other group. The bridge examines the destination of each packet to determine whether to transmit it to the other side. See also switch. broadband High bandwidth network technology that multiplexes multiple, independent carriers to carry voice, video, data, and other interactive services over a single cable. A communications medium that can transmit a relatively large amount of data in a given time period. A frequently used synonym for cable TV that can describe any technology capable of delivering multiple channels and services. broadcast Simultaneous transmission to multiple network devices; a protocol mechanism supporting group and universal addressing. See also multicast and unicast. C CableHome A project of CableLabs and technology suppliers to develop interface specifications for extending high-quality, cable-based services to home network devices. It addresses issues such as device interoperability, QoS, and network management. CableHome will enable cable service providers to offer more services over HFC. It will improve consumer convenience by providing cable-delivered services throughout the home. CableLabs A research consortium that defines the interface requirements for cable modems and acknowledges that tested equipment complies with DOCSIS. cable modem A device installed at a subscriber location to provide data communications over an HFC network. Unless otherwise specified, all references to “cable modem” in this documentation refer to DOCSIS or Euro-DOCSIS cable modems only. cable modem configuration file File containing operational parameters that a cable modem or gateway downloads from the Internet Service provider TFTP server during registration. Class C network An IP network containing up to 253 hosts. 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
B Glossary 108 This document is uncontrolled pending incorporation in PDM TERM DEFINITION 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’s location. CPE can be provided by the subscriber or the Internet Service provider. Also called a client. crosstalk An undesired signal interfering with the desired signal. D 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.
B Glossary 109 This document is uncontrolled pending incorporation in PDM TERM DEFINITION 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 SBG901 is simultaneously a DHCP client and a DHCP server. A DHCP server at the cable system headend assigns a public IP address to the SBG901 and optionally to clients on the SBG901 LAN. The SBG901 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. DNS The Domain Name System is the Internet system for converting domain names to IP addresses. A DNS server contains a table matching domain names, such as Internetname.com, to IP addresses, such as 192.169.9.1. 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.
B Glossary 110 This document is uncontrolled pending incorporation in PDM TERM DEFINITION 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 A 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 SBG901 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. For example, there are drivers for printers, monitors, graphics adapters, modems, Ethernet, USB, HPNA, and many others. DSSS Direct Sequence Spread Spectrum is an IEEE 802.11b RF modulation protocol. dynamic IP address An IP address that is temporarily leased to a host by a DHCP server. The opposite of static IP address. E encapsulate To introduce data into some other data unit to hide the format of the data. encode To alter an electronic signal so that only an authorized user can unscramble it to view the information. encrypt To encode data. Ethernet The most widely used LAN type, also known as IEEE 802.3. The most common Ethernet networks are 10Base-T, which provide transmission speeds up to 10 Mbps, usually over unshielded, twisted-pair wire terminated with RJ-45 connectors. Fast Ethernet (100Base-T) provides
B Glossary 111 This document is uncontrolled pending incorporation in PDM TERM DEFINITION speeds up to 100 Mbps. “Base” means “baseband technology” and “T” means “twisted pair cable.” Each Ethernet port has a physical address called the MAC address. Euro-DOCSIS A ComLabs standard that is DOCSIS adapted for use in Europe. event A message generated by a device to inform an operator or the network management system that something has occurred. expansion slot A connection point in a computer where a circuit board can be inserted to add new capabilities. F F-type connector A type of connector used to connect coaxial cable to equipment such as the SBG901. firewall A security software system on the SBG901 that enforces an access control policy between the Internet and the SBG901 LAN. flow A data path moving in one direction. FEC Forward error correction is a technique to correct transmission errors without requiring the transmitter to resend any data. FMDA Frequency Division Multiple Access is a method to allow multiple users to share a specific radio spectrum. Each active user is assigned an individual RF channel (or carrier), with the carrier frequency of each channel offset from its adjacent channels by an amount equal to the channel spacing, which allows the required bandwidth per channel. Frame A unit of data transmitted between network nodes that contain addressing and protocol control data. Some control frames contain no data. frequency Number of times an electromagnetic signal repeats an identical cycle in a unit of time, usually one second, measured in Hz, kHz, MHz, or GHz. FTP File Transfer Protocol is a standard Internet protocol for exchanging files between computers. FTP is commonly used to download programs and other files to a computer from web pages on Internet servers. full-duplex The ability to simultaneously transmit and receive data. See also half-
B Glossary 112 This document is uncontrolled pending incorporation in PDM TERM DEFINITION duplex. G gain The extent to which a signal is boosted.

Latency The time required for a signal to pass through a device. It is often expressed in a quantity of symbols. LED light-emitting diode LNS An L2TP network server is a termination point for L2TP tunnels where PPP frames are processed and passed to higher layer protocols. LNS can operate on any platform that terminates PPP. The LNS handles the server side of the L2TP protocol. L2TP relies only on the single media over which L2TP tunnels arrive. The LNS can have a single LAN or WAN interface, but can terminate calls arriving at any of the LAC’s full range of PPP interfaces (asynchronous, synchronous, ISDN, V.120, etc.). The LNS initiates outgoing calls and receives incoming calls. LNS is analogous to a home gateway in L2F technology. loopback A test that loops the transmit signal to the receive signal. Usually, the loopback test is initiated on a network device. The test is used to verify a path or to measure the quality of a signal on that path.

P packet The unit of data that is routed between the sender and destination on the Internet or other packet-switched network. When data, such as an e-mail message, is sent over the Internet, the sender’s IP divides the data into uniquely-numbered packets. The packet header contains the source and destination IP addresses. The individual packets may travel different routes. When all packets arrive at the destination, IP at that end reassembles the packets. packet-switched A scheme to handle transmissions on a connectionless network such as the Internet.

Q 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.
