Glossary
channel
channel A generic term for a communications path on a given medium;
multiplexing techniques allow providers to put multiple channels over a
single medium.
Channel
Associated
Signaling (CAS) A form of circuit state signaling in which the circuit state is indicated by
one or more bits of signaling status sent repetitively and associated with
that specific circuit.
CIDR Classless Inter-Domain Routing. CIDR is a new addressing scheme for
the Internet which allows for more efficient allocation of IP addresses
than the old Class A, B, and C address scheme.
Circuit
Identifier This is a character string specified by the circuit vendor, and is useful
when communicating with the vendor during the troubleshooting
process.
Clear Channel A digital circuit where no framing or control bits (i.e. for signaling) are
required, thus making the full bandwidth available for communications.
For example, a 56 Kbps circuit is typically a 64 Kbps digital circuit with
8 Kbps used for signaling. Sometimes called Switched-56.
CLI Command Line Interface
Classless
Routing See CIDR
cold-standby In a redundant DS3 controller setup, the standby controller can be in two
states, the hot-standby signifies that the
card is ready to go active
(healthy) but for some reason (code of the 2 controllers is not the
same) it will need to reconfigure the box when it goes active,
which will be service affecting.
Also see hot-standby.
Command Line The command line is where you enter MS-DOS commands.
Community
Name String that defines an administrative relationship between SNMP
entities.
