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)

s D-channel.
