l If Conclusion is not Normal, rectify the fault based on the displayed test conclusion. Then,
go to Step 4.
NOTE
For example, if Conclusion is Phone not connected, the phone is faulty or the line between the phone
and the device is not connected properly. In this case, replace the phone or ensure that the line is connected
properly.
Step 4 Check whether the fault is rectified.
l If the fault is rectified, go to Step 16.
l If the fault persists, go to Step 5.
Step 5 Run the pots circuit-test command to perform a 8.3 POTS Subscriber Circuit Line Test on
the affected port.
l If the results of all test items are Normal, the user port is functional. Go to Step 8.
l If the results of only some test items are Normal, the user port is faulty. Go to Step 6.
Step 6 Connect the phone to another port on the same board, and check whether the fault is rectified.
l If the fault is rectified, the original user port is faulty. Go to Step 16.
l If the fault persists, go to Step 7.
Step 7 Replace the voice service board and check whether the fault is rectified.
l If the fault is rectified, go to Step 16.
l If the fault persists, go to Step 8.
Step 8 Run the display boardframeid/slotid command to check whether the state of the DSP daughter
board is Normal.
l If the state is Normal, go to Step 9
l If the state is not Normal, go to Step 15
Step 9 Run the display pstn state command to check whether CTPAdmState of the affected POTS
port is StartSvc.
l If CTPAdmState is StartSvc, go to Step 11.
l If CTPAdmState is not StartSvc, go to Step 10.
Step 10 Run the undo endservice command to reactivate the service on the port, and check whether the
fault is rectified.
l If the fault is rectified, go to Step 16.
l If the fault persists, go to Step 11.
Step 11 Ensure that the media gateway (MG) interface is functional. Then, check whether the fault is
rectified.
NOTE
Check whether the following conditions are met:
l Run the display if-h248 all command in H.248 mode or the display if-sip all command in SIP mode to
check whether the media gateway (MG) interface is working properly.
l Check whether the MG interface configuration on MA5612 is the same as that on the interconnected media
gateway controller (MGC).
l Check whether the MA5612 communicates with the MGC properly.
l If the fault is rectified, go to Step 16.
l If the fault persists, go to Step 12.
