Remote Logon Procedure — $n=pw
The remote logon procedure is required to access a secure V.3600.
When calling into the secure V.3600 from a remote location the user is
prompted to enter a password. The password must be entered as
$n=pw
where
n
is the user number and
pw
is the user’s password.
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 V.3600 drops the call.
If the password entry is correct the secure modem sends the
P
ASSWORD 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 V.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 V.3600, all status
messages and control leads which would notify the local DTE of the
incoming call are suppressed. The secure V.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.
