List of terms

bandwidth-elastic connection

See elastic connection (page 47).

bandwidth-non-elastic connection

See non-elastic connection (page 90).

bandwidth management

Allows both connectionless and path-oriented traffic to share the same Nortel Multiservice Switch trunk while ensuring that trunk bandwidth is not oversubscribed to by circuits carrying voice and video traffic. Bandwidth is reserved for the duration of a logical connection and can be partitioned among services according to their priorities, minimizing the probability that voice and video traffic is discarded.

bandwidth on demand (BWOD)

Capability enabling users to acquire varying amounts of bandwidth on request.

bandwidth pools

In ATM traffic management, a method of reserving by service category a percentage of link bandwidth (known as a bandwidth pool) for connections.

basic rate interface (BRI)

The interface between an ISDN subscriber and the ISDN switch (that is, the local loop). The interface consists of two 64 kbit/s B-channels and one 16 kbit/ s D-channel.

basic virtual path terminator

A type of virtual path terminator that provides traffic management at the VC level only.

Bc

See committed burst size (Bc) (page 30).

BC

See bus controller (BC) (page 22).

BCD

See binary-coded decimal (BCD) (page 19).

BCI

See backward congestion indication (BCI) (page 17).

BCS
