Security Password
Entry Techniques
The
previous sections described how to set up and
configure your network for dial access security
. Once
configured and enabled, you must now supply a password
to originate or answer a call.
The following examples demonstrate how to enter an
Answer Access security password string and an Originate
Access password string. Note that dial access security
messages, that may appear on the LCD, are listed in
Table 4-6 in Chapter 4.
Answer Access Password (VF-Side and
DTE-Side Entry Techniques)
Answer
Access password security uses two password
entry techniques: VF-side password and DTE-side
password entry
. A VF-side password consists of DTMF
tones and is entered by the originating caller via the AT
command set, the DCP
, or manually with an attached
telephone.
A VF-side password can be entered with the A
T dial
command. The following examples illustrate two ways to
enter a VF-side password:
TYPE: ATDT5551234W12345678#
or
ATDP5551234T@12345678#
PRESS: Enter
Where: A
TD
is the A
T dial command.
P
and
T
are Pulse dial and Tone (DTMF)
dial modifiers.
5551234 is the phone number. 5551234
is the phone number.
W
is the second dial tone dial modifiers.
@ is the wait for quiet answer dial
modifiers.
12345678
is the password. VF-side
passwords must consist of 1–8 decimal
digits.
# is the password terminator character.
NOTE
While pulse dial can be used to
originate the call, DTMF tones
must be used for the password.
This can be accomplished by
using the P and T modifiers
appropriately. Refer to the Dial
command in Chapter 14,
AT
Command Set and S-Registers
,
for more information about
modifiers.
Some originating modems may not recognize the
W modifier as a wait for second dial tone. If your call
disconnects due to a VF Password T
imeout or an
Unknown VF Password, first verify that the answering
3800 Series modem’s VF Prompt Type is set for 2nd Dial
Tone. Next, verify that the Dial Tone Detect configuration
option in the originating modem is enabled. Third, insert
several Pause (,) modifiers into the dial string instead of
the W modifier. (For the 3800 Series modem, each Pause,
which is determined by the Pause Time configuration
option (S8), is equal to 2 seconds.) This allows a delay
between the processing of the phone number by the
answering modem and the transmission of the VF-side
password by the originating modem.
Some experimentation may be necessary to determine
the number of pauses necessary for your call.
