Maintenance-Object Repair Procedures
d. The exact failure cause is unknown or has been mapped to one of these
values. If this is a permanent condition, try reversing the direction of the
Administered Connection (originate the administered connection from the
destination switch). This may yield another failure cause.
e. The destination endpoint is not available. Check the status of the
destination endpoint at the far-end switch. The status for the destination
endpoint will not be available on the switch where this error is logged. At
the far end, use status access-endpoint or status data-module to see
whether the endpoint is busy, out-of-service or otherwise unavailable.
f. This switch sent an ISDN message to another switch that either did not
respond (18) or did not respond within the allotted time (102). This could
be due to link failure, or congestion, or an outage at the other switch.
g. The address of the destination endpoint has changed. Change the
administered connection accordingly. The destination endpoint will not be
administered on the switch where this error is logged.
h. These errors indicate that a resource (for example, a circuit or bearer
capability) required by the administered connection is not currently
available.
i. A network failure (38) or temporary failure (41) has occurred. Error Log
entries for other MOs (for example, DS1-BD) may indicate a local problem.
