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.
