MCMP Backup

Backup may be achieved in one of five ways:
Case 1 – Dedicated MCMP Backup with
Switched 56 DBMs ( Figure 4-21). In this case, two
DBM-Ss are dedicated to the control DSU-
MCMP. Two tributary DSUs are equipped with a
Switched 56 DBM and MCMP. A DSU with a
TDM circuit card configured for extended bridge
(EBrdg) mode is used to bridge the aggregate data
stream to the DBMs.

4-28
If the control DSU-MCMP is enabled for
Aggregate Switching, aggregate data (data,
framing, and diagnostics) is routed from the spare
Port 1 interface on the control DSU-MCMP to the
extended bridge.
The extended bridge should be configured for
Bridge Timing set to Auto. The control and
tributary DSUs should have Disruptive Type set to
Br56. The tributary DSUs should be configured for
MCMP Backup set to MCMP.
