Security
The V.3600 series of modems provides three features to assure secure
operation of the modem. These features are front panel password
protection, autocallback, and secure mode of operation. Front panel
password protection is discussed in Chapter 4.
Two levels of major security operation are available: high and low. The
AT
commands for each level are explained below.
IMPORTANT: Security requires that you have available your
“superuser” password, explained in the “Superuser” section on page 8-6
and in the “Setting Passwords — $Pn=pw$pw” section on page 8-8.
Systems administrator functions cannot be accessed without this
password. If you forget the superuser password, contact Technical
Support. Refer to “Calling Technical Support” section on page 12-2.
Autocallback Security
Autocallback is an additional security feature that is separate from Low
and High Security. Autocallback forces an answering modem to dial the
selected autodial (
*AUn
) telephone number after answering a call, holding
the line for one second, and then disconnecting. When autocallback is
enabled the modem will not train on a direct call. Access autocallback via
Main Menu #5 on the LCD. Refer to Chapter 4 for further information.
S72
enables/disables autocallback.
S78
determines the delay in seconds
before autocallback is initiated.
