network condition. This alarm
indicates a QoS fallback.
ITG0204 DSP device reset. A DSP failed to
respond and was reset.
ITG0206 Invalid A07 message received.
Message discarded. A07 is a message
signaling interface between Meridian 1
and the IP trunk card.
ITG0207 Unknown H.323 message
received. Message discarded.
ITG0208 Backup Leader has been activated.
Leader card not

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.

Fault Clearing Action
Recurrent QoS fallback and recovery can
indicate network faults, far-end IP Trunk
3.01 (and later) node failure or network QoS
configuration errors.
If this alarm occurs repeatedly on the same
DSP, replace the card. See
trunk card" (page
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)
Indicates unsupported H.323 gateway is
misconfigured to send messages to IP
Trunk 3.01 (and later). Locate address that
is sending unsupported messages.
Investigate why Active Leader failed. Either
Leader 0 or Leader 1 can perform the Active
Leader or Backup Leader role.
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)
If this occurs frequently, contact Nortel
