∙With level 2 security, redial the phone number corresponding to the dial-in password. The line simply disconnects if the password does not match.

User Passwords

Fifty user passwords may be defined. The corresponding 50 dial- back numbers are the modem’s 50 stored phone numbers. Any character (ASCII 0-127) can be used in the password, the maximum password length is 8 characters.

Security functions are only accessible through AT commands in terminal mode. Any access attempt will result in the modem’s prompting the user to enter the supervisor password. The attempt will be rejected if the entered password is not correct. The default supervisor password is ZyXEL when the modem is shipped from the factory. This supervisor password is also the password sent for automatic password checking in a type 1 connection. To modify the supervisor password, use AT*HS.

You will be asked for the original password and a new password and then to re-enter the new password for verification. For example:

Password: (Enter supervisor password)

********

Password: (Enter new supervisor password)

********

The command AT*V will list the 50 user passwords and the supervisor password on the screen for viewing. Again, you will be prompted to enter the supervisor password first.
