Remote Access Feature
Description
User Interaction
A caller has three chances to enter the correct barrier code. An inter-digit
time-out occurs during the first attempt, even if the dialed digits are incorrect.
The system only processes the valid number of digits. A dial tone is given after
the correct code is entered. If the caller enters more than the correct number
of digits, the system uses the time-out to hide the correct number of digits.
The time-out recurs until the caller has dialed the eleventh digit--giving the
impression that additional digits are required--even if the barrier code length
is shorter. A distinctive tone sounds after an incorrect entry. After three
incorrect entries, the system disconnects the caller.

The steps below describe a normal Remote Access call. An ARS Remote
Access call is dialed just as any other ARS call is dialed. Calls made
by Remote Access users, rather than users on networked external systems,
are dialed as described below.

The following steps describe a Remote Access call:
- The caller dials into a line, described above, that accepts Remote Access
calls. Personal Lines light steady green.
- If a barrier code is not required, the caller hears a dial tone and proceeds
to Step 4.
- If a barrier code is required, the caller dials the code.
A barrier code cannot begin with * (star) or contain two *s:
- If a correct barrier code is entered, the caller hears a dial tone and
proceeds to Step 4. If an incorrect barrier code is entered, the caller
hears an alternating high-low tone followed by a dial tone, and can enter
the barrier code again. Up to three attempts are allowed.
- If the caller enters an incorrect barrier code, he or she hears a retry
tone 15 seconds after the system determines that the code is invalid. During
this step, the caller can enter two asterisks (**) to erase the entry. This
is treated as a failed attempt. The system then erases the code entry and
sends a retry tone for another attempt at entering the barrier code (unless
this was the caller's third attempt). If the caller fails all three attempts
at entering the code, he or she hears the reorder dial tone and is eventually
disconnected by the system.
- After successfully entering a barrier code, the caller may now enter a telephone
number, pool number, ARS code, or maintenance code.
