Appendix D. Glossary

BERT

Bit error rate test. A test that uses any of a number of stress patterns to test T3, T1, FT1, and DDS circuits.

bipolar

A signal containing both positive and negative amplitude components.

bipolar violation See BPV.

bit

A binary digit representing a signal, wave, or state as either a one or a zero. A bit is the smallest unit of information a computer can process.

bit error

The receipt of an encoded bit that differs from what was sent by the transmitter.

bit rate

The speed at which bits are transmitted, usually expressed in bits per second (bps).

bps

Bits per second. The number of bits passing a specific point per second. Exam- ples of common rates are kbps (one thousand bits per second) and Mbps (one million bits per second). T3 operates at 44.736 Mbps.

BPV

Bipolar violation. A violation in the alternate mark inversion (AMI) line code for which consecutive 1s are represented by pulses of opposite polarity. BPVs that are not intentional (B8ZS) are counted as errors. Could also be the presence of two consecutive 1 bits of the same polarity on the T-carrier line.

bridge

A data communications device that connects two or more networks and forwards packets between them.
