8-12 Modem 3600
If the password entry is incorrect, the password entry field will be
cleared and the remote user will be allowed further entries until the
number of invalid attempts matches the lockout threshold stored in S77.
At this point the secure Modem 3600 drops the call.
If the password entry is correct the secure modem sends the
PASSWORD ACCEPTED message to the remote site. Depending on
the assigned security level, the user is given
• Immediate access to the DTE connected to the secure modem,
• A callback sequence, or
• A callback with password reentry.
When the call is terminated from either end the secure Modem 3600
automatically resets itself to the secure mode for the next remote or
local user.
While a remote caller is initiating a call to the secure Modem 3600, all
status messages and control leads which would notify the local DTE of
the incoming call are suppressed. The secure Modem 3600 uses the
value stored in S0 to determine the number of rings on which to
autoanswer. If S0 is set to 0 incoming calls will not be answered.
If a local user is logged on during an incoming call, a RING message is
displayed but the call will not be answered until the local user logs off,
issues an A command, or presses the TALK/DATA button.
If the local user logs off, the call will be answered and the remote user
must follow the normal password procedure. If the local user enters A or
presses TALK/DATA the call to the remote user connects normally.
