Modifying the User Passwords
Use command [AT*Hn] to modify the "n"th user password (n=0-39). The system will ask you to
enter the supervisory password first and then the user password you want to modify. Use the
command [AT*V] to list the 40 user passwords and the supervisor password on screen for viewing.
Non-password Auto Call Back Function
In addition to the standard modem-like security functions described in the previous section, the
omni.net provides another simpler call back function that does not require any password check.
The Calling Party Number (origination address) will be checked against the 5 pre-stored call-back
numbers before the B-channel is connected. If the CPN is matched with any one of the numbers, the
incoming call will be dropped (without connection, hence without any charge) and the omni.net
will automatically call back the CPN using the matched phone number.
The non-password auto callback function can be controlled using the following AT commands:
# AT*GC0 - disable the auto call back function (default).
# AT*GC1 - enable the auto call back function.
The pre-stored numbers can be set using the following [AT*HCn] command:
AT*HCn
Password:
******** (Enter new supervisory password)
Call back phone number:
********
OK
The [AT*VC] command can be used to list all the pre-stored numbers.
