l
If the service is not restored, go to
.
Step 4
Check whether the modem parameter configurations on the local MA5612 and peer MA5612
are consistent with the data plan.
NOTE
The query method is as follows:
l
Run the
display modem parameters
command to query the modem parameter configurations.
l
Run the
display fax-modem parameters
command to query the public modem parameter configurations.
l
Run the
display dsp attribute
command to query the DSP parameter configurations.
l
If the modem parameter configurations on the local MA5612 and peer MA5612 are
consistent with the data plan, go to
.
l
If they are not consistent with the data plan, go to
Step 5
Modify the modem parameter configurations so they are consistent with the data plan, and then
check whether the service is restored.
NOTE
The modification method is as follows:
l
Run the
modem parameters
command to modify the modem parameter configurations.
l
Run the
fax-modem parameters
command to modify the public modem parameter configurations.
l
Run the
dsp attribute
command to modify the DSP parameter configurations.
l
If the service is restored, go to
l
If the service is not restored, go to
.
Step 6
Have an MGC maintenance engineer check whether the modem service data configurations on
the MGC are consistent with the data plan.
l
If the configurations are consistent with the data plan, go to
l
If they are not consistent with the data plan, go to
Step 7
Have the MGC maintenance engineer modify the modem service data configurations on the
MGC so that they are consistent with the data plan. Then, check whether the service is restored.
l
If the service is restored, go to
l
If the service is not restored, go to
.
Step 8
Check whether the quality of the bearer network meets the requirements of the modem service.
NOTE
Users can use a tool to test the bearer network quality or run the
ping
command on the MA5612 to ping the peer
access gateway (AG). The packet loss ratio must be less than 0.5%.
l
If the peer AG cannot be pinged or the packet loss ratio is too high, go to
l
If the peer AG cannot be pinged and there is no packet loss, go to
.
Step 9
Check whether the network connection between the MA5612 and the peer AG is normal and
whether the transmission devices are normal. If there are faults on the network or devices, rectify
the faults and ensure that the peer AG can be pinged from the MA5612 and that there is no packet
loss. Then, check whether the service is restored.
l
If the service is restored, go to
l
If the service is not restored, go to
