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.

Authorization
Protocol
(CHAP) 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.
CLI Command Line Interface
CMG Customer Media Gateway.
CODEC 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.
Command Line The command line is where you enter MS-DOS commands.
CSU 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.
DHCP Dynamic Host Configuration Protocol. DHCP is a network configuration
that allows maintenance to be performed from a central site rather than
by end users.
