FAIL

MM710 detects a Loss of Signal alarm. The physical link is broken or 
the remote DS1 endpoint is down. All trunks or ports of this MM710 are 
out-of-service. 

1. Check the physical connection of the MM710 Interface Media 

Module and the cable.

2. Check the physical connection of the MM710 Interface Media 

Module to the terminating device. 

3. Check premise distribution system (or intra-premise wiring) for 

physical connection failures.

4. If the MM710 connects to a T1 network facility, call the vendor of the 

T1 carrier to diagnose the remote DS1 endpoint. 

5. If the MM710 Interface Media Module connects directly to a switch, 

call the system technician of the remote switch to diagnose the DS1 
endpoint. 

6. If the MM710 connects to a line-side terminating device such as a 

PRI terminal adapter, contact the vendor of the line-side terminating 
device to diagnose the equipment.
