Security & Encryption
Your modem has many sophisticated security features. Your modem limits caller access by
means of user names and passwords. User names and passwords are stored in the modem’s non-
volatile memory. With each user name and password a modem command of up to 30 characters
may be specified. This allows the implementation of callback to users.
Callback is where the modem rings a specified phone number. Even if an unauthorised caller
manages to break the modem’s security, that caller must be connected to the phone number
specified in the remote modem’s database. Also discussed in this section is the topic of DES
(Data Encryption Standard) encryption, which allows you to encrypt data being passed to a
remote modem.
The Security Menu
All additions and changes to your modem’s user and password lists are performed through the
Security Menu. This menu is displayed when you use the #S command.
• Type: AT#S <E>
A prompt will appear: Enter Security Password:
When you first receive your modem, all passwords will be set as a single Carriage Return
(ENTER).
• Press the ENTER key
The Security Menu will be displayed.

Entering a Security Password
You may choose to have a dedicated security password, thus changing the password assigned for
the first security user. To enter a new security password:
• Select Option 8 from the Security Menu <E>
You will be prompted to enter a new security password. Your modem is case insensitive. Up
to 8 characters may be used, including spaces.
When you enter your password, each character will appear on the screen as a # character.
• Type in your new password <E>
You will be prompted to re-enter the new security password.
• Type in your new password again <E>
Your new password will be stored in your modem’s non-volatile memory.
