your convenience. If this type of radio reset alarm is severe enough
to cause a problem, it will be identified as a Halt Count (see below).
Hlt:<halt count>
Persistent Download Failures or complete hardware failures have
caused the Base Station to go out of service. A count of one for this
type of radio reset is cause for alarm. Disconnect and then reconnect
the power to the Base Station.If the halt count re-occurs, replace the
Base Station.
ALARM C240
Evaluation Base Station <Base Station number> has lost
synchronization <count> times.
Description This alarm occurs when synchronization has been lost
four or more times. Synchronization Failure occurs when a Base
Station experiences a problem with digital frame synchronization on
the TCM cable connecting it to the Controller. The Base Station or
the Controller receives incomplete frames from the other and the
shared frame reference point is lost. Automatic resynchronization
occurs upon detection of a synchronization failure. Information
being transmitted during the synchronization failure may be
corrupted or lost. Lost synchronization can be caused by faulty
RJ-11 connectors, a TCM cable that is faulty, too long, or bridge-
tapped, or a hardware problem in the Base Station.
Action
1. Check the RJ-11 connectors and the TCM cable between the
Controller and the distribution block. Replace them if necessary.
2. Check the RJ-11 connectors and the TCM cable between the
distribution block and the Base Station. Replace them if
necessary.
3. If the problem persists, replace the Base Station.
ALARM C250
Evaluation Base Station <Base Station number> has lost
integrity <count> times.
Description This alarm occurs when integrity has been lost four or
more times. Lost Integrity occurs when corrupted data is received by
the Base Station from the Controller. Lost integrity is transient and
is usually caused by a problem with the connection between the Base
