WARNING C251
Evaluation Base Station <Base Station number> has lost
integrity <count> time(s).
Description This warning occurs when integrity has been lost fewer
than four 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 Station and the Controller. Lost integrity 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.
