Automatic Route Selection and Toll Control
4. DETAILED DESCRIPTION ’Introduction
4.01The ARS feature is part of the Generic 1003 software packages
of the SX-200 DIGITAL PABX, which automatically selects one
of a preprogrammed list of Trunk Routes every time an outgoing call is
made. The routes are selected via the digits dialed, in order of cost
(i.e., least expensive route first), and in accordance with the caller’s toll
restriction. The use of digit analysis and digit modification within the
ARS...

4.06Every peripheral device‘which is capable of accessing a trunk is
assigned a class of restriction 
(COR). These CORs are arranged
within COR Groups, which are associated with Trunk Groups through
the programming of the Route Definition table. The Route Definition
table defines:(l) a trunk group, (2) how the digits dialed are to be
modified, and (3) which classes of restriction CANNOT access the
route. A maximum of 50 COR Groups, each containing a maximum of
25 COR members,...

than 1 second for a IO-digit number). If no overlap outpulsing is
enabled, the delay for a lo-digit number outpulsed over a dial pulse
trunk would be approximately 16 seconds at 10 PPS.4.11Trunk Routes are seized only after the ARS process has deter-
mined the validity of the call with respect to the caller’s class
of restriction. In this way, false traffic will not be generated at the CO
(or distant PABX) by aborted seizures.

5. ARS TABLES
General5.01The ARS package is a network of tables, each of which contains
data relevant to the setting up of a trunk call, such as routing
options and 
CORs. The tables are interconnected through a series of
indices and pointers. A total of nine tables make up the ARS network.
They are, in order of programming:
ARS Digit Strings Table
ARS Nested Digit Strings Table
ARS Maximum Number of Dialed Digits.
Route Plans Table

completed and a trunk seized. A YES or NO value is entered via
the appropriate softkey on the Attendant Console or CDE termi-

Restricted COR Group:This field is optional, and may be

“Digits to be Analyzed” field, the TAB key may be pressed to
permit entering information into the next field; when the line is
entered into CDE, the words “no digits to analyze” will appear
by default.
Quantity to Follow:This programmable field specifies the
number of digits to be dialed AFTER the digits to be analyzed,
and may be specified as “UNKNOWN”. The advantage of speci-
