Security
8-2 Modem 3600
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.
