MG-DS1 (DS1 Interface Media Module)
210 Maintenance of the Avaya G350 Media Gateway
June 2004
1 to 88 FAIL The test failed because the MG-DS1 interface Media Module and the remote
DS1 endpoint are not synchronized to the same clock rate. The MG-DS1
interface Media Module detected a slip alarm. The error code equals the
number of slips detected by the MG-DS1 interface Media Module since the
last slip alarm inquiry test.
If the MG-DS1 connects to a T1 network facility or to another switch, do the
following:
1
Retry the command at 1-minute intervals for a maximum of
5 times.
2
For a DS1 interface Media Module, enter the list
measurement ds1-log GGGVS command to read the
error seconds measurement.
3
Verify that both endpoints of the DS1 link are administered
using the same signaling mode, framing mode, and line
coding.
4
Contact T1 Network Service or the technician at the remote
switch to diagnose the remote DS1 endpoint.
5
Check the physical connectivity of the MG-DS1 interface
Media Modules and the cable.
6
Replace the local MG-DS1 interface Media Module, and
repeat the test.
1 to 88
(cont.) FAIL
(cont’d.) If the MG-DS1 connects to a line-side terminating device (for example, a
PRI terminal adapter), do the following:
1
Retry the command at 1-minute intervals for a maximum of
5 times.
2
Enter the list measurement ds1-log GGGVS command
to read the error seconds measurement.
3
Verify that the switch DS1 and the line-side terminating
device are administered using the same signaling mode,
framing mode, and line coding.
4
Investigate the maintenance status of the line-side
terminating device. Refer to the ’Line-Side Terminating
Device Operating Manual’ for information.
5
Contact the vendor of the line-side terminating device to
diagnose the equipment.
6
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.
7
Replace the local MG-DS1 interface Media Module and
repeat the test.
