Control Channel Transmission Test (#94)
Control channel messages are sent from the SPE to selected port circuit packs
and the response from the port circuit packs is checked. This tests the ability of
the Switch Control to send and receive messages on the control channel of the
TDM Bus.

ABORT
The port circuit packs necessary for this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2. If the test continues to abort, then replace the Processor circuit pack.

ABORT
Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
0
FAIL
The Switch Control cannot communicate on the TDM Bus control channel.
The customer probably cannot make or receive calls.
1. Run the Short Test Sequence several times to make sure 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. Remember that the Long Test Sequence is destructive.
Placing and receiving calls is affected for several seconds.
2. If there are no TDM Bus alarms against the Standby TDM Bus, switch
the control channel from its current bus to the Standby bus. If this test
passes on the new bus, investigate the possibility of TDM Bus failures. If
the test fails even after the control channel is switched to the standby
TDM Bus, proceed to Step 3.
3. If calls cannot be made, replace the Processor board.
PASS
The Switch Control can communicate with the port circuit packs over the
TDM Bus.
