Carrier Access CMG Router Bridge, Challenge Handshake Authorization Protocol Chap, Command Line

Glossary

bridge	A bridge is any hardware device that connects two physically distinct
	network segments, usually at a lower network layer than would a router,
	however the two terms are often interchanged. A device that connects
	two local-area networks (LANs), or two segments of the same LAN. The
	two LANs being connected can be alike or dissimilar. Unlike routers,
	bridges are protocol independent. They simply forward packets without
	analyzing and re-routing messages. Consequently, they're faster than
	routers, but also less versatile.

Handshake Authorization Protocol (CHAP)

CLI

CMG

CODEC

Command Line

CSU

DHCP

A strong authentication method used with PPP for user login. A type of authentication in which the authentication agent (typically a network server) sends the client program a key to be used to encrypt the user name and password. This enables the user name and password to be transmitted in an encrypted form to protect them against eavesdroppers. When using CHAP, the user name/password is sent encrypted over the connection, preventing sniffing. See also PAP.

Command Line Interface

Customer Media Gateway.

CODEC stands for CODer-DECoder. The CODEC converts voice signals from their analog form to digital signals for digital transmission, and then converts those digital signals back to analog so you may hear the call.

The command line is where you enter MS-DOS commands.

Channel Service Unit. The first device encountered by a T1 line entering a facility. It protects the equipment beyond it from damage due to disturbances on the T1 line and regenerates the T1 signal to meet T1 specifications.

Dynamic Host Configuration Protocol. DHCP is a network configuration that allows maintenance to be performed from a central site rather than by end users.
