391
Alarm
Description
Fault Clearing Action
ITG0203
Fallback to PSTN activated. Bad
network condition. This alarm
indicates a QoS fallback.
Recurrent QoS fallback and recovery can
indicate network faults, far-end IP Trunk
3.01 (and later) node failure or network
QoS configuration errors.
ITG0204
DSP device reset. A DSP failed to
respond and was reset.
If this alarm occurs repeatedly on the same
DSP, replace the card. See
ITG0206
Invalid A07 message received.
Message discarded. A07 is a
message signaling interface between
Meridian 1 and the IP trunk card.
Verify that the card type is correctly
configured in the system. Print TNB in LD
20. Ensure that the card is configured as a
TIE Trunk with:
XTRK = ITG1 (for SMC 32-port)
XTRK=ITG2 (for ITG-Pentium 24-port)
ITG0207
Unknown H.323 message
received. Message discarded.
Indicates unsupported H.323 gateway is
misconfigured to send messages to IP
Trunk 3.01 (and later). Locate address
that is sending unsupported messages.
ITG0208
Backup Leader has been activated.
Leader card not
responding.
Investigate why Active Leader failed.
Either Leader 0 or Leader 1 can perform
the Active Leader or Backup Leader role.
ITG220
Upgrading with old software version
(unknown processor type).
ITG0250
Invalid X12 message received.
Message discarded.
Verify that the card type is correctly
configured in the system. Print TNB in LD
20. Ensure that the card is configured as a
TIE Trunk with:
XTRK = ITG1 (SMC 32-port)
XTRK = ITG2 (ITG-Pentium 24-port)
Major Alarms – Intervention required, but not immediately
This fault class can result in a trap that automatically resets a processor on the card and clears the
fault after a service interruption of several seconds or minutes. The talk path is cut off for existing
calls and no new calls can be made on the card until it finishes resetting.
If the problem occurs frequently the IP trunk card requires manual intervention; for example,
upgrade to an enhanced software version or replace the IP trunk card.
ITG0300
Memory allocation failure. Check
configuration. Indicates a dynamic
memory allocation problem.
If this occurs frequently, contact Nortel
technical support.
