Integrity areas (Alarms C240 and C250, and Warnings C241 and
C251). If this is the source of the problem, replace the TCM cable
and RJ-11 connectors. If this problem persists, an alarm will be
generated, signifying a problem that should be fixed at that time.
DF:<download failure count>
An intermittent hardware or software problem exists that occurs
only during Base Station or RIM initialization. This type of radio
reset does not cause any problems for the user during normal
wireless system operation. If this problem persists, an alarm will be
generated, signifying a problem that should be fixed at that time.
WARNING C241
Evaluation Base Station <Base Station number> has lost
synchronization <count> time(s).
Description This warning occurs when synchronization has been
lost fewer than four 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.
