Switch Control Reset Test (#93)
This test is destructive.
This test resets the Switch Control and determines if it can successfully go
through its initialization sequence. The test is destructive since there is the
possibility of losing some control messages to or from port circuit packs.
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.
1. This failure could be due to either a Netcon circuit pack failure or the
loss of system timing signals. If the Switch Control is alarmed, then
suspect a Netcon circuit pack failure. If the Switch Control is not
alarmed, investigate the possible loss of system timing signals before
replacing the 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 Netcon board.
4. If calls cannot be made, replace the Netcon board immediately.
5. The procedure for replacing the Network Control circuit pack
(DATA-BD) in a High or Critical Reliability system is described in
Chapter 6, ‘‘
Reliability Systems: A Maintenance Aid’’. The procedure
for doing the same in systems without High or Critical Reliability is
described in Chapter 5, ‘‘
Routine Maintenance Procedures’’.
PASS The control channel interface between the processor and the Switch
Control is working correctly.
