utomatic Route Selection (ARS)
Description
Automatic Route Selection (ARS) is a system programmable feature
that automatically selects the least expensive route available at the
time an outgoing outside call is made. Preprogramming eliminates
dialing the access code of the least expensive carrier. All the user
has to do is dial the feature number for ARS, and the number. The
appropriate outside line is selected and the access code is added
before the number is outpulsed.
Conditions
• A Toll Restriction check is done before ARS is applied.
• ARS works according to the selected dialing plan. Thus, if the user
dialed number is not found in the dialing plan (Leading Digit Tables),
the dialed number is sent out by a Local Access (Automatic line access)
Code.
• ARS is not applied to a call specifying an outside line. In other words,
it is possible to make an outside call by assigning an outside line
directly (ARS Override).
• This feature also applies to Call Forwarding – to Outside Line.

Programming Example
The following is an example to show how to program ARS so that the user
can call the XYZ Company via the least expensive line.
Step 1. Program ARS to work when the feature number for ARS is dialed
by the user. Use the program [312] ARS Mode to enable the feature.
Step 2. Store the telephone number of the outside party that will use the
ARS feature. For example, if XYZ Company’s telephone number is “1-
234-567-8910” (not including the line access code), store the leading digits
of the number “1234567890” (max. 10 digits). To store the numbers, use
one of the programs [314] through [321] ARS Leading Digit Entry for
Plans 1 through 8 (Leading Digit Tables 1 through 8). The following
assumes that we have selected Leading Digit Table 1 to store the number.
Remember that Table number 1 matches Route Plan Table 1.
