Automatic Route Selection (ARS) Feature |
|
Description |
ARS is available only in Hybrid/PBX mode. ARS allows outgoing calls to be dynamically routed over selected facilities after dialing an ARS access code (usually 9). This enables the system to select the least expensive route for each call.

|
Local system users (Hybrid/PBX mode only) can use ARS to access lines/trunks connected to another MERLIN MAGIX Integrated System or to a DEFINITY Enterprise Communications Server (ECS) or DEFINITY ProLogix Solutions system. The connection to the networked system is made by using tandem tie (T1-emulated or analog) or tandem PRI trunks. Details about setting up and planning this functionality are provided in Tandem Switching. Detailed information about private networks is included in the Network Reference. |
Programmable lists, called tables, indicate the desired routes (line/trunk facilities) for specified area codes and/or exchanges. There is a different ARS table for each type of call (local, toll, special number, and so on). The tables are chosen according to the telephone number digits that are dialed by a user. Each ARS table has a particular pool to which it routes calls.
