Security

Low Security Operation

Low security operation provides password protection against unauthorized dial-up access. High security is another feature which is discussed later in the “High Security” section on pa ge8-4. The security feature can be enabled/disabled with AT commands when operating on a dial-up system.

Transmitted data and received data lines are suppressed to the host DTE during security validation; all other signals (CTS, DSR, RI, etc.) operate as selected. After the password has been validated, the modem operates normally.

Operating without Low Security

The modem is not factory set for security and operates like a standard V.34, except for additional AT commands which allow access to security. With these commands a user can set passwords and turn security on. When security is enabled, a password must be used to change security options.

Operating with Low Security

A secure modem will not allow data transfer between its host and a remote host until a correct password is received from the calling party. If an incorrect password is received the secure modem disconnects. The front panel is not locked out because this type of security prevents unauthorized dial-up access.

Remote Operation

The originating modem must transmit the correct security code before the secure modem will allow data transfer. If accessing a secure remote modem, the local modem prompts the user with

PLEASE ENTER YOUR PASSWORD ?

To respond to the password prompt, enter

AT$

followed by the password.
