Description

Automatic Route Selection (ARS) is available only in Hybrid/PBX mode. ARS

allows outgoing calls to be dynamically routed over selected trunk facilities.

ARS allows the system to be programmed to select the least expensive route for

each call.

Programmable lists, called tables, indicate the desired routes for specified area

codes and/or exchanges. A table contains some or all of the following types of

information:

■ Table Type: An indicator of how the information in the table is to be

interpreted. Table types are Area Code, Local Exchange, 6-Digit, 1 +7,

Dial 0, Special Numbers (N11), Default Toll, and Default Local. Details for

each table type are discussed later in this section.

■ Digit Strings: An array of 3-digit entries in the table. These are typically

Area Codes or Exchanges. Dialed digits are compared to the stored

digits. A match should occur in only one table, and therefore cause

selection of the routes specified in that table.

■ Subpattern: An array of up to six routes. There are 2 subpatterns for all

tables except the Special Numbers (N11) and Dial 0 tables. The

subpattern selected depends on the time of day that the call is made,

and the start time associated with each subpattern. (The start time for

Subpattern A is specified as the stop time for Subpattern B.)

The Special Numbers (N11) Table always uses the main pool and thus

has neither subpatterns or routes. The Dial 0 Table has no subpatterns

and only one route.
