Reference Guide for the Model XM128 ISDN Digital Modem You are asked to enter the original password, to enter a new password, and then to reenter the new password for verification. For example, you are prompted with the following: Password: Enter the current supervisory password at this prompt. You are then prompted for a new password. Password: Enter the new supervisory password at this prompt. You are then prompted to verify the new password. Verify: Enter the new supervisory password again at this prompt. You should receive the following response: OK The supervisory password is now modified. Use the command AT*Hn to modify the nth user password. You are prompted to enter the supervisory password first; then the user's password for this entry is requested and verified. The command AT*V lists both the 40 user passwords and the supervisor password on the screen for viewing. Nonpassword Auto Callback Function In addition to the standard modem-like security functions described in the previous section, the Model XM128 modem provides another simpler callback function. The calling party number (origination address) is checked against the five prestored callback numbers before the B channel is connected. If the CPN is matched with any one of the numbers, the incoming call is rejected (without connection and without any charge) and the Model XM128 modem automatically calls back using the matched phone number. Table B-3 lists the auto callback commands. Table B-3. Auto callback commands Command Description AT*GC0 This command disables the auto callback function (default).
