Error
Code Description
3842 A request has been made
to use a transit network or
common carrier that cannot
be accessed.
3843 No route to destination.
Request received to route
call through a transit
network that is recognized
but not allowed to carry the
call or not able to serve the
destination.
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.
3858 Similar to Error Type 1.
The switch sent an ISDN
message to the far-end
switch or terminal adapter
that did not respond in the
allotted time.
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).
8-980 Issue 1 May 2002
Recommendation
1. From the circuit pack and port number (in the Aux Data
field), determine the trunk group against which the error
was reported.
2. Check every routing pattern containing this trunk group
for validity of interexchange carriers requested (IXC
field).
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 that 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.
Follow same recommendations as for Error Type 1.
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 every routing pattern containing this
trunk group to route calls around the network that is out
of service.
