3846 The far-end switch has
indicated that the B-channel
(trunk) is not acceptable for
use in the call for which it
was requested. This could indicate an administration
problem (for example, the local switch and
the far-end switch have different B-channels
administered), or could reflect the
occurrence of a normal race condition (for
example, the local switch has requested use
of a B-channel which the far-end switch had
just reserved for use on another call).
1. From the circuit pack and port number
(in the Aux Data field), determine the
trunk group against which the error was
reported.
2. Issue the status trunk command for the
indicated trunk.
3. Refer to the “DS1 ISDN Trunk Service
States” and “ISDN-PRI Trunk Service
States” sections of ISDN-TRK for
recovery suggestions.
3858 The switch sent an ISDN
message to the far-end
switch or terminal adapter
which did not respond in the
allotted time. Possible causes include link failure and
congestion or outage at the far-end.
3878 The far-end switch has
indicated that the network is
not functioning correctly
and that the condition may
last a relatively long period
of time (for example,
immediately re-attempting
the call may not be
successful). 1. From the circuit pack and port number
(in the Aux Data field, determine the
trunk group against which the error was
reported.
2. Consult with the network provider to
determine the nature and expected
duration of the out of service condition.
3. Consider modifying all routing patterns
containing this trunk group, to route calls
around the network which is out of
service.
