10-218 Issue 4 May 2002
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. Table 10-81 provides more information about this range of Error
Codes:

Error
Code Description Recommendation
3842 A request has been made
to use a transit network or
common carrier that cannot
be accessed.
From the circuit pack and port number (in the
Aux Data field), determine the trunk group
against which the error was reported.
1. 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)
■ 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 Table 10-65 on page 10-195 in
‘‘ATM-BCH (ATM B-Channel Trunk)’’ for
recovery suggestions.
3858 Similar to Error Type 1. The
switch sent an ISDN
message to the far-end
switch or terminal adapter
which did not respond in the
allotted time.
1. Check for alarms and errors against link
components
2. Check out other errors against
‘‘ATM-SGRP (ATM Signaling Group)’’,
‘‘ATM-TRK (Circuit Emulation Service
Circuit Pack)’’, and other hardware
components on the link.
