To support the talk battery alarm feature, each LCM shelf must be
provisioned with a WLC. Special provisioning rules are not available, with
regard to this feature, to dictate where the WLC can reside in the shelf. If
the maintenance line card in LSG 0 Card 0 for the LCM shelf is assigned as
a WLC, the feature can use this card. This line card tests the ringing
generators.
The MAP commands that can Bsy the last available WLC on an LCM shelf
are modified to issue a warning message if this condition occurs. Three
commands can cause this situation. The first condition is the Bsy command
at the LTP MAP level when a WLC is posted. The second condition is the
Diag command at the LTP MAP level when a WLC is posted. Diagnostics
ManB the WLC for a short time. The third condition is the Bsy Drwr
command at the PM MAP level when an LCM is posted. If one of these
commands causes the last available WLC on the LCM shelf to Bsy, a
warning message appears. Refer to the following example.
Example of a MAP response:
Busying the last available WLC on LCM shelf.
prevents testing for talk battery failure on the LCM
shelf. Minor alarm will be raised within one minute
unless WLC becomes available.
The Querypm Flt command is modified to display the new ISTb reasons by
shelf and line equipment number (LEN) for the two alarm conditions. Refer
to the following examples.
