User Passwords - ZyXEL Communications U-336E User Manual

With level 1 security, the local modem will maintain the
connection if the password is OK, otherwise the line
disconnected.
With level 2 security, dial back 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.
