MG-DS1 (DS1 Interface Media Module)
Maintenance of the Avaya G350 Media Gateway 207
June 2004
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.
If the MG-DS1 connects to a T1 network facility or to another switch, do
the following:
1
The performance of the DS1 link between the MG-DS1
interface Media Module and the remote DS1 endpoint is
poor. Enter the
list measurement ds1-log GGGVS
command to read the error seconds measurement.
2
Verify that both endpoints of the DS1 link are administered
using the same signaling mode, framing mode, and line
coding.
3
Contact T1 Network Service or the technician at the remote
switch to diagnose the equipment.
4
Check the physical connectivity of the MG-DS1 interface
Media Modules and the cable.
5
Replace the local MG-DS1 interface Media Module, and
repeat the test.
FAIL
(cont’d.) If the MG-DS1 connects to a line-side terminating device (for example, a
PRI terminal adapter), do the following:
1
The performance of the DS1 link between the MG-DS1
interface Media Module and the line-side terminating device
is very poor. Enter the
list measurement ds1-log
GGGVS command to read the error seconds measurement.
2
Verify that the switch DS1 and the line-side terminating
device are administered using the same signaling mode,
framing mode, and line coding.
3
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.
4
Contact the vendor of the line-side terminating device to
diagnose the equipment.
5
Check the physical connection of the MG-DS1 interface
Media Module to the terminating device, and check the
premise distribution system (or the intra-premise wiring) for
physical connection failures.
6
Replace the local MG-DS1 interface Media Module and
repeat the test.
