Glossary
This glossary defines terms and lists acronyms used with the SBG900.
A
access point A device that provides WLAN connectivity to wireless clients (stations). The SBG900 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
translation
See NAT.
ALG Application level gateway triggers are required by some file transfer (for example, FTP), game, and
video conferencing applications 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
size.
ANSI The American National Standards Institute is a non-profit, independent organization supported by
trade organizations, industry, and professional societies for standards development in the United
States. This organization defined ASCII and represents the United States to the International
Organization for Standardization.
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 SBG900 responds with a message containing its MAC address. Subsequently, data
sent by the computer uses the SBG900 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.
asynchronous
timing
The SBG900 uses synchronous timing for upstream data transmissions. The CMTS broadcasts
messages that bandwidth is available. The SBG900 reserves data bytes requiring x-number of
mini-slots. The CMTS replies that it can receive data at a specified time (synchronized). At the
specified time, the SBG900 transmits the x-number of data bytes.
attenuation The difference between transmitted and received power resulting from loss through equipment,
transmission lines, or other devices; usually expressed in decibels.
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 SBG900 Ethernet port and any computer, printer, or hub.
