Case 2 – Backing Up The Channels To The Most Important Tributary Location - Paradyne 3610 Application Manual

Case 2 – Backing up as many channels as
possible to the one most important tributary
location ( Figure 4-22). In this case, the control
DSU and the one tributary DSU selected for dial
backup must be equipped with a DBM configured
with MCMP Backup set to TDM. Essentially, the
backup becomes dial backup of a point-to-point
TDM circuit.
Because the backup is performed in TDM mode,
both TDM and MCMP configuration options must

be set. Therefore, Port 1 at the control DSU should
be mapped to Port 1 at the tributary DSU. For
Case 1, only two DSD groups can be supported
( MCMP mode normally supports three DSD
groups), and the inbound pseudo-carrier control
configuration options ( RxCarrSel and TxCarrSel )
need to be set for backup ( Cntrl). All other
tributary locations are not served until the alarm is
fixed and the MCMP circuit is restored.
