!SecurityAlert:

ARS should always be used for the best security protection.

This section contains instructions for using Automatic Route Selection (ARS) to allow the most cost-effective use of lines/trunks connected to the system, which can mean significant savings for the customer’s business. Routing calls efficiently is especially important when the business has several different types of lines/trunks, such as local, WATS, FX, or tie, or uses more than one long-distance company. If the system is pooled, you can use ARS to specify which trunk pool should be used for each call, based on the telephone number the caller dials.

ARS tables can be used to route calls across a private network and out to the PSTN using a remote system’s trunks. See Network Reference for information on how to set up ARS for the private network.

With ARS, users must dial a ￿ before dialing any 10-digit toll number, even if the local telephone company does not require a toll-call prefix.

You can define up to 16 ARS tables, each divided into two subpatterns based on the time of day. Four additional tables are factory-set and are designed to save programming time.

In this section, you define a set of ARS tables. This set includes a list of area codes and exchanges associated with each table, the preferred and alternate routes (if any) for each subpattern, and the Facility Restriction Level (FRL) for each route. As the system manager becomes more familiar with the calling patterns of the company and with the intricacies of ARS, he or she may want to change these patterns to suit the particular installation.

ARS Worksheet 4

This section contains instructions for completing the ARS worksheet (Form 3e) to decide how to best route calls.

For each trunk pool, you identify the trunk pool number, type of trunk (local, FX, regional WATS, and so on), whether the calls are toll or local calls, and the number of area codes or exchanges the pool should serve.

When placing a toll call using ARS, callers dial one of the following:

■11 Digits. 1 + 3 (area code) + 3 (exchange) + 4 (last 4 digits of the number)

■8 Digits. 1 + 3 (exchange) + 4 (last 4 digits of the number)

■7 Digits. 3 (exchange) + 4 (last 4 digits of the number)
