Restricted Numbers Programming
Description:
Program restricted numbers as entries in the toll restriction table. The system will accept up to
400 entries.
Each restricted number can be up to 16 digits long and can be comprised of the
digits O-9 Plus the “match any” digit (@) if needed.
If you program the system to include the automatic route selection (ARS) feature, always fill
out the restricted numbers with the @ digit as shown in the following examples:
for l+dialing, enter l@@@@@@@@@@,
for local dialing, enter @ @ @ @ @ @ @,
for l+ 7-digit dialing, enter valid exchanges and the @ digit--either enter 1555 @ @ @ @ or enter
555 @ @ @ @ with the 1 added by the ARS modify digit table.
When you make this arrangement, you ensure that ARS will wait until the user dials all the
number’s digits before it determines if all routes are busy. This eliminates the possibility of the
user accidentally dialing an intercom number or a feature code.
You can enter a pause at the end of a restricted number’s digit string to indicate that dialing is
complete. Do this by typing a P or p after you type the digit string. The pause entry
distinguishes this restricted number as unique. You can enter the same digits without the pause
but instead followed by additional digits as another unique number. You can assign different
routing and toll restriction parameters to each of these entries. There are several applications for
this feature. One application is in international dialing where different toll restriction parameters
apply depending upon whether the caller dialed 0 or 011. In this case, you can enter 0 pause to
access local lines and 01 to access international lines. Another application is with tie line calling
where a remote extension is the same digits as an office or area code that you need to enter in
the restriction table. By entering nnn pause for tie line access and nnn@ for CO line access, the
system can route the call over the proper line. A third application is brought forth with the
advent of the new North American Numbering Plan (NANP). With NANP, an area code may be
the same digits as a local office code. You can enter nnn@ @ @ @ pause for local line access
and nnn @ @ @ @ @ @ @ for long distance line access. In any application, the system resets its
pause timer after receiving each caller dialed digit. If the timer expires before the caller dials
another digit, the system routes the call based on the digits preceding the pause. If, instead, the
system detects more digits instead of a pause, it routes the call based on the entire digit string.
You can enable the pause entry ability using the Section 6.10.5 programming procedure;
however, the following Section 11.6.1 procedure for entering the restriction number digits also
includes the pause enabling procedure.
