Appendix G. Glossary

B8ZS

Bipolar eight zero substitution. In a T1 carrier system, a specific eight bit pattern containing two delib- erate bipolar violations which replaces eight consecutive customer zero bits.

bandwidth

The transmission capacity of a communications channel, stated in megabits per second (Mbps).

BECN

Backward Explicit Congestion Notification. Sent to the device generating excessive frame relay traffic as a means to slow down the flow of data to the network. Compare with FECN.

bit

Bit is a contraction of the term binary digit. It is the smallest unit of information a computer can pro- cess representing either high or low, yes or no, or 1 or 0. It is the basic unit in data communications. A bit can have a value of zero (a mark) or one (a space).

bps

Bits per second. A measure of the speed of data communications.

BRI

Basic Rate ISDN. An ISDN service that offers two bearer (B) channels. One channel (64 kbps) is used for data transfer and as a data-link. The second channel (16 kbps) is used for signaling and control information.

Burst

A sporadic increase in a transmission.

Bursty traffic

Traffic that alternates between steady transmission and short bursts of high transmission.

byte

Eight bits of information composed of zeros or ones, one of which may include a parity bit.

CIR

Committed Information Rate. The guaranteed bandwidth available for customer data under normal circumstances.

Companding

The process of compressing and expanding a signal.

clocking

An oscillator-generated signal that provides a timing reference for a transmission link. A clock pro- vides signals used in a transmission system to control the timing of certain functions. The clock has two functions, (1) to generate periodic signals for synchronization and (2) to provide a time base.

CPE

Customer premise equipment. All telecommunications terminal equipment located on the customer premises, including telephone sets, private branch exchanges (PBXs), data terminals, and customer- owned coin-operated telephones.

CS

See CTS.
