1) Carry out the show mg ag all command on the ETG to check
if the corresponding IAD has been successfully registered.
2) Carry out the show port command on the IAD to check if the
port and the corresponding subscriber phone set are normal.
If they are not normal, it is usually caused by subscriber
board faults.
3) If the IAD port is normal, carry out the show pstn-port
command on the ETG to show the IAD port status. If the
status is not normal, it is generally because the L3 address
does not correspond or the subscriber data has not been
configured.
Note:

Different IADs may have different models and are produced by different
manufacturers; therefore, their numbering modes may be different. The port IDs
of the IAD108 starts with 0.
z
The IP console must correspond to two user IDs, and the first port ID must be an
even number.
8.2.3 Processing Procedure
According the fault phenomena and causes analyzed above, the
processing procedures are as follows.
1) Make test calls to confirm that some port cannot process
dialing but other ports can. Then check the external line to
rule out related causes.
