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.
1. This failure could be due to either a NetPkt or Netcon circuit
pack failure or the loss of system timing signals. If the
Switch Control is alarmed, then suspect a NetPkt or Netcon
circuit pack failure. If the Switch Control is not alarmed,
investigate the possible loss of system timing signals
before replacing the NetPkt or Netcon 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 NetPkt or
Netcon board.
4. If calls cannot be made, replace the NetPkt or Netcon
board immediately.
PASS
The control channel interface between the processor and the
Switch Control is working correctly.
