Clearing MG 1000E faults

Clearing ELAN network interface faults
On each MG 1000E, the MGC card connects to the ELAN subnet through
the ELAN network interface. A CAT5 or 100BaseT Ethernet cable connects
the ELAN network interface to a Layer 2 switch on the ELAN subnet.
This provides speech path switching and transmit and receive signaling
messages.
Faults related to the ELAN network interface can cause system initializations,
disable conference capability, or disable all terminal connections (such as
trunks and telephones) on a card. ELAN network interface faults can also
make functional equipment appear faulty.
