*Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer
to the appropriate test description and follow the recommended procedures.
Notes:
• (a) This switch sent a message to the far-end switch or terminal adapter, and the far-end did not
respond in the allotted time. Possible causes include link failure and congestion or outage at the far-
end. The Aux Data field contains Layer 3 protocol information used by internal counters.
If no other symptoms are present, no action is required. If Layer 3 communication is down, there
should be indications in the form of alarms and errors for link components. Check out other errors
against ISDN-SGR, ISDN-TRK, and other hardware components on the link.
There is no test to clear these errors. The error counter is decremented by 1 every 15 minutes.
• (b) This error indicates that the primary signaling channel connection has been lost for more than
90 seconds. If a secondary signaling channel does not exist or is not in-service, the associated B-
channels will be placed in the ISDN Maintenance/Far-End state. The B-channels will not be usable
for outgoing calls, although incoming calls will still be accepted. The switch will automatically
attempt to recover the signaling link. Pay particular attention to the results of Test #636 (Primary
Signaling Link Hardware Check) in the test sequence. When the link does recover, the B-channels
will be negotiated back to the In-Service state and their alarms will be retired.
