Multipoint Full Dial Backup with
Nondisruptive Diagnostics
The multipoint network in Figure D-6 consists of a
Model 3611 DSU with a digital bridge and two DBM-Ss,
and two a Model 3610 DSUs with Switched 56 DBMs.
Since the DSUs are configured for nondisruptive
diagnostics (Diag Type: NonD), in-band framing is
necessary, and all DSU/DTE interfaces operate at
55600 bps. In addition, it is assumed that the host polls for
all data traffic.
In this scenario, the dial backup process will be
initiated and controlled from the 6800 Series NMS (a
6700 Series NMS can also be used). All tributary DSUs
should be listed in the control DSU’s poll list.
NOTE
For this scenario, DBM-Ss are
used; however, DBM-Ds can
also be used.
