ATM-SGRP (ATM Signaling Group)
g. Error Type 2305: The Remote Layer 3 Query (#637) failed. A specific message was sent to
the far-end switch, and it did not respond within the time allowed.
1. Investigate elements of the ATM D-Chel(s) (ATM-DCH) for both this switch and the
far-end switch.
If Test #637 fails twice in a row, the B-Chels are alarmed and made unavailable for
outgoing calls (although incoming calls are still accepted). When Test #637 succeeds and
the far-end switch starts responding properly, the ATM trunk (B-Chels) are placed back into
normal operation and their alarms retired.
h. Error Type 3585: A SERV or SERV ACK ISDN D-chel message has been received by a
non-US-type interface (country option other than 1 on the DS1 administration screen).
However, these messages are used only for duplex NFAS signaling, which is supported by
country protocol 1.
Thus, there may be a mismatch in administration between the local and far-end switches.
1. Consult with the customer’s network provider to determine whether the D-Chel is set
up correctly on the far-end switch.
i. Error Type 3840-3928: These Error Types report certain error messages received by the
ATM-SGRP Signaling Group for one of its associated B-Chels. The Aux Data field is the
port number of the B chel from which 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 recommended action 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.
See Table 48: Descriptions and repair recommendations (Error Types 3840-3928) for
more information.

Description Recommendation
3842 A request has been
made to use a transit
network or common
carrier that cot 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 every routing pattern containing this trunk
group for validity of interexchange carriers requested
(IXC field).
