    Glossary This glossary defines terms and lists acronyms used with the SBG901. Table 34 Glossary TERM DEFINITION 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.
  • Page 106 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...
  • Page 107 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.
  • Page 108 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.
  • Page 109 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”...
  • Page 110 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.
  • Page 111 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.
  • Page 112 TERM DEFINITION duplex. gain The extent to which a signal is boosted. A high-gain antenna increases the wireless signal level to increase the distance the signal can travel and remain usable. gateway A device that enables communication between networks using different protocols.
  • Page 113 TERM DEFINITION hops a packet traverses toward its destination (called the hop count) is saved in the packet header. For example, a hop count of six means the packet has traversed six routers. The packet hop count increases as the time-to-live (TTL) value decreases. host In IP, a host is any computer supporting end-user applications or services with full two-way network access.

IGMP establishes and maintains a database of group multicast addresses and interfaces to which a multicast router forwards multicast packets.
  • Page 115 TERM DEFINITION 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 SBG901 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.
