Clearing Core faults

The MGC card in the MG 1000T Core is the primary processor for the
MG 1000T platform. It performs system control and switching for the MG
1000T Core and Expansions.
Faults on the MG 1000T Core can stop call processing on the MG 1000T.
In addition, other equipment may not operate properly while there is an
MG 1000T Core fault in the system.

Action
If there are no messages indicating
a fault on any conference loop, test
each conference loop in the system
by entering:
LD 38
CNFC loop ("loop" represents the
conference loop number)
If the conference loop is disabled, try
to enable it by entering:
LD 38
ENLL loop ("loop" represents the
conference loop number)
Install a new NTDK20 SSC circuit
card.
Reuse the daughterboards and
security device attached to the
original NTDK20 SSC circuit card.
If the card tests "OK", the NTDK20
SSC circuit card was defective.
If after a few minutes the problem
reoccurs, replace the Media Gateway.
