1.6 Originating Features
Automatic 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 CO call is made. ARS applies to an
outgoing CO call made by dialling the feature number for Local Access / ARS (9: [SP], 0:
[NL], [JT] = default). Pre-programming eliminates the need of dialling the access code of the
least expensive carrier. The appropriate Trunk Group is selected and the carrier access code is
added before the number is outpulsed.
System Programming Example (See "System Programming" section in the
Programming Guide)
The following shows how to programme ARS so that the extension user can call the XYZ
Company via the least expensive line.
Step 1. To utilise ARS feature, set "Automatic Route Selection" in "System-Tenant" to "Yes."
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 7 digits of the number "1234567" and associated Routing Plan
No. (01 for example) in "ARS - Leading Digits Table."

Step 3. Check all carriers available to call the stored telephone number and their Trunk Groups.
Supposing that there are three carriers available to call the XYZ Company and each carrier's
line is assigned to a Trunk Group as follows:
Carrier E — Trunk Group 1
Carrier F — Trunk Group 2
Carrier G —Trunk Group 3
Then check the fee charged by each carrier:
