VF Passwords
VF passwords consist of DTMF tones and are entered
by the originating caller using the AT Dial (D) command,
or the keypad of an attached telephone. They must consist
of eight decimal digits, 0 through 9, and are terminated
with the # symbol. For example, if 11223344 is a valid VF
password on the 3821Plus modem at the telephone
number 555-4321, it can be accessed with this command:
ATDT555-4321@11223344#
If pulse dialing must be used, the VF password must
still be sent in DTMF tones. This can be done using a
combination of P (pulse) and T (tone) dial modifiers:
ATDP555-4321TW11223344#
The requirement of the @ (wait for quiet answer) or
W (wait for second dial tone) dial modifier depends on the
VF_Prompt_Type selected in the Security configuration
options group of the Configure branch. For more
information about dial modifiers, see the Dial (Dn)
command.
DTE Passwords
DTE passwords are entered by the originating caller
from the DTE keyboard. They may consist of six
characters, and may be a combination of decimal digits 0
through 9 and the letters A through Z (uppercase or
lowercase).
Up to 3,000 VF and DTE passwords can be stored in
the password table in the memory of the 3821Plus
modem. Each password is indexed by a number, 0001
through 3000. The index number is used when displaying
or changing a password.
Originate Security
An Originate Access password is entered by a local
user to gain access to a local 3821Plus modem. This
password must be embedded in the AT dial command.
The password must be defined as a DTE_Entry type in the
password table.
The following example describes how to enter an
Originate Access security password:
TYPE: ATD%C2C3D2%T18135551234
Where: ATD is the AT dial command.
% is the start and stop dial string
command interrupt characters; the
Originate Access password must be
enclosed by these characters.
C2C3D2 is the alphanumeric 6-character
Originate Access password on the local
modem.
T is the Tone (DTMF) dial modifier.
18135551234 is the phone number of a
remote modem.

Answer Security
DTE passwords alone, or a combination of both VF
and DTE passwords, may be used for Answer Security.
With VF and DTE Security, modems negotiate VF
password entry before training. If successful, the modems
connect and then prompt the user for a valid DTE
password.
Another combination is called VF with DTE Security.
In this case, the modem will accept as valid only the DTE
password whose password table entry immediately
follows that of the VF password that was received. For
example, if the VF password at index number 9 is used to
connect, the DTE password at index number 10 is the
only valid DTE password.
The Password Type option of the EditPassWdTable
group determines whether VF and DTE Security or VF
with DTE Security is used.
