A
access point | A device that provides WLAN connectivity to wireless clients (stations). The SBG940 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 | 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 | A standard system used to designate the size of electrical conductors; gauge numbers are inverse to |
Gauge (AWG) | size. |
ANSI | The American National Standards Institute is a |
| 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 SBG940 responds with a message containing its MAC address. Subsequently, data |
| sent by the computer uses the SBG940 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 | The SBG940 uses synchronous timing for upstream data transmissions. The CMTS broadcasts |
timing | messages that bandwidth is available. The SBG940 reserves data bytes requiring |
| |
| specified time, the SBG940 transmits the |
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. |
| Automatic |
| reversing the send and receive pins on any port. It enables the use of |
| the SBG940 Ethernet port and any computer, printer, or hub. |
