Notes:
a. Error Type 0: Run the short test sequence first. If every test passes, run the long test
sequence. Refer to each appropriate test’s description, and follow its recommended
procedures.
b. Error Type 1: 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 screen of alarms and errors for link components. Check
for other errors against ISDN-SGR, ISDN-TRK, and other hardware components on the
link.
There is no test to clear these errors. An error counter is decremented by 1 every 15
minutes, and the error eventually will be cleared by the system.
c. Error Type 257: the primary signaling chel connection has been lost for more than 90
seconds. If a secondary signaling chel does not exist or is not in service, the associated
B-Chels will be placed in the ISDN Maintenance/Far-End state. The B-Chels will not be
usable for outgoing calls, although incoming calls will still be accepted. The switch will
automatically attempt to recover the signaling link. Check the results of the Primary
