User Interaction
Beginning with Release 3.0, the caller has three chances to enter the correct
barrier code. An inter-digit timeout 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 you enter more
than the correct number of digits, the system uses the timeout to hide the
correct number of digits. The timeout 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 following steps describe a remote access call.
1. The caller dials into a line/trunk that accepts remote access callers. (The
lines/trunks are described in the section above.) Personal lines light
steady green.
2. If a barrier code is not required, the caller hears a dial tone and proceeds
to Step 4.
3. If a barrier code is required, the caller dials the code.
