MG-DS1 (DS1 Interface Media Module)
Issue 1 June 2005 1629
FAIL Minor alarms are often accompanied by slip and misframe alarms against
the board. Trunk alarms and hardware error logs may occur on the
associated trunks.
The performance of the DS1 link between the MM710 interface Media
Module and the remote DS1 endpoint is poor. Enter the list
measurement ds1-log location command to read the error
seconds measurement.
If the MM710 connects to a T1 network facility or to another switch, do
the following:
1. Verify that both endpoints of the DS1 link are administered using the
same signaling mode, framing mode, and line coding.
2. Check the physical connectivity of the MM710 interface Media
Modules and the cable.
3. Replace the local MM710 interface Media Module, and repeat the
test.
4. Contact T1 Network Service or the technician at the remote switch to
diagnose the equipment.

If the MM710 connects to a line-side terminating device (for example, a
PRI terminal adapter), do the following:
1. Verify that the switch DS1 and the line-side terminating device are
administered using the same signaling mode, framing mode, and
line coding.
2. Investigate the maintenance status of the line-side terminating
device. Obtain the error seconds measurement on the terminating
device (if possible). Refer to the 'Line-Side Terminating Device
Operating Manual' for information.
3. Check the physical connection of the MM710 interface Media
Module to the terminating device, and check the premise distribution
system (or the intra-premise wiring) for physical connection failures.
4. Replace the local MM710 interface Media Module and repeat the
test.
5. Contact the vendor of the line-side terminating device to diagnose
the equipment.
PASS No Minor alarm is detected in the MM710 Interface Media Module.
