h. These error codes are used to report certain error messages received by
the ISDN-PRI Signaling Group for one of its associated B-channels. The
aux data field shows for which B-channel (port number) the message was
received.
The error code generated equals 3840+
x
, where
x
is a Cause Value
defined by the ISDN PRI Specification. Note that there is no Test to Clear
Value for these error types; selected ISDN cause values are placed in the
log when they are received, but no direct action or alarming is performed
solely in response to receiving them. They provide added data that may
prove useful when tracking down obscure networking and routing
problems. The following table provides more information:

Code Description Recommendation
3842 A request has been made
to use a transit network or
common carrier that cannot
be accessed.
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 all routing patterns containing this trunk group
for validity of interexchange carriers requested (IXC
field).
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.
