l If the test result (shown in Conclusion) is not Normal, rectify the fault based on the test
result. Then, go to Step 8.
NOTE
If the test result shown in Conclusion is Phone not connected, the phone is faulty or the line between the
phone and the MA5612 is not properly connected. In this case, replace the phone or check whether the
line is connected properly.
Step 8 Pick the phone off the hook again and check whether a dial tone is heard.
l If a dial tone is heard, go to Step 16.
l If no dial tone is heard, proceed to Step 9.
Step 9 On the MGC, query subscriber data and check whether data of the subscriber who encounters
the fault is configured on the MGC.
l If data of the subscriber who encounters the fault is configured on the MGC, go to Step
11.
l If data of the subscriber who encounters the fault is not configured on the MGC, configure
such data on the MGC. Then, proceed to Step 10.
Step 10 Pick the phone off the hook again and check whether a dial tone is heard.
l If a dial tone is heard, go to Step 16.
l If no dial tone is heard, proceed to Step 11.
Step 11 On the MGC, trace H.248 signaling, and check whether error 502 is contained in H.248 signaling.
l If error 502 is contained in H.248 signaling, run the tid-template modify command to
modify the terminal ID format of the MG to be the same as that of the MGC. In the H.248
mode, run the reset coldstart command to reset the MG interface and make the subscriber
register again. Then, go to Step 14.
l If error 502 is not contained in H.248 signaling, go to Step 15.
NOTE
In the protocol, error 502 is defined as invalid termination point, including RTP termination point and
physical termination point. On the MGC, if the traced H.248 signaling contains error 502, it indicates that
the terminal ID format of the MG is different from that of the MGC. For example, RTP configured on the
MGC is in a progressively increase format of RTP1000, RTP1001 and RTP1002; however, RTP configured
on the MG is in a progressively increase format of RTP500, RTP501 and RTP502.
Step 12 In the SIP mode, run the reset command to reset the SIP interface and make the subscriber
register again. If registration is successful, run the display pstn state command in the global
config mode to check whether the service management state (CTPAdmState) of the POTS port
is StartSvc.
CAUTION
In resetting the MG interface, subscriber services carried on this interface will be interrupted.
Therefore, before resetting the MG interface, ensure that no users under this interface are running
services.
l If CTPAdmState is StartSvc, go to Step 14.
l If CTPAdmState is not StartSvc, proceed to Step 13.
