Control Channel Interface Test (#92)
Loop back messages are sent to the Switch Control via the interface used for
control channel messages. The messages are returned to the SPE for verification
via the same interface.

other FAIL Messages could not be looped back through the control channel interface. If
this is a standard system, the customer probably cannot make or receive calls.
PASS The control channel interface between the processor and the Switch Control is
working correctly.

Description/ Recommendation
1. Retry the command at 1-minute intervals a maximum of 5 times.
1. This failure could be due to either a Processor circuit pack failure or the
loss of system timing signals. If the Switch Control is alarmed, then suspect
a Processor circuit pack failure. If the Switch Control is not alarmed,
investigate the possible loss of system timing signals before replacing the
Processor circuit pack. Test #94 also fails if the system timing signals are
lost. If Test #94 passes, do not suspect the loss of timing signals.
2. Run the Short Test Sequence several times to make sure that this failure is
occurring consistently, run the Long Test Sequence to reset the Switch
Control. Sometimes running the Long Test Sequence may clear the
problem. If the test is still failing, proceed to Step 3 or 4.
3. If the system can process calls, replace the Processor board.
4. If calls cannot be made, replace the Processor board immediately.
