ISDN-TRK (DS1 ISDN Trunk)
Issue 1 June 2005 1453
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: Disagreement between this switch and the switch at the other end of the
trunk connection with regard to the ISDN call state of the DS1 ISDN Trunk. This switch will
automatically try to recover by clearing the call, (that is, call will be torn down). You can use
status trunk grp#/mem# to determine the state of the trunk.
When running the short test sequence, pay close attention to the results of the Call State
Audit test (#257).
c. Error Type 15: Software audit error and does not indicate a hardware malfunction. Run the
short test sequence, and investigate associated errors.
d. Error Type 19: Possible protocol mismatch or far end may be out of service.
e. Error Type 129: The far-end switch changed its ISDN service state to either out of service
or maintenance. This may be either a temporary condition due to far-end testing of that
trunk or a hardware problem with the trunk. Outgoing calls will not be allowed over the trunk.
To investigate the status of the trunk, enter status trunk grp#/mem#.
