To end the backup session via the NMS, issue
disconnect commands to the control DSU and all its
DBM-Ss. (The NMS restores all control and tributary
DSUs to the DDS network and drops all dial backup calls
by issuing an sf command and release in the Standby
Facility State field to the control DSU, and an sf
command and release in the Standby Facility State field
command followed by a dial and a q command in the
Number to Dial field to each DBM associated with the
digital bridge. To end the backup session via the SDCP,
address the control DSU and each DBM by issuing the
DrBu (drop backup) command.
Ending the backup session causes the control DSU to
deactivate the bridge, and DSU timing (56 kbps) becomes
the DDS clock source once again. Each DBM-S signals its
tributary that it is dropping the call and hangs up. Each
tributary then switches back to the DDS network, and the
DDS network is again functional. (Between the time that
the bridge is deactivated and the DDS network is
reestablished, errors occur on those tributaries still in
backup.)
Pertinent configuration options for the central-site
bridge, a DBM-S, and tributary DSU-DBMs supporting
the nondisruptive diagnostics configuration. Please note
that all DBM-Ss here should be configured the same –
only the passwords and telephone numbers should differ.
The same holds true for the tributary DSU-DBMs.
