Digital Bridge; Multipoint With Digital Bridging - Paradyne 3610 Application Manual

Digital Bridge

A TDM or MCMP circuit card can be configured to
perform digital bridge capability. This is a special case of
digital sharing where all active ports on the bridge are
configured to one digital-sharing group with or without
contention. A digital bridge can be configured as a
central-site bridge (CBrdg), or an extended bridge
(EBrdg) when more bridging capability is needed.

The digital bridge capability allows for multipoint
transmission from a local digital bridge ( Figure 4-28 ), as
opposed to network bridging. The DTE connected to the
DSU having the digital bridge capability is the controlling
DTE.
The digital bridge capability is used primarily in
COMSPHERE 3000 Series Carrier applications,
providing dedicated dial backup for multipoint DDS
circuits. One TDM or MCMP circuit card configured as
CBrdg provides bridging capability, depending upon the
application.
