AT&T AT&T manual Considerations

The following tones are associated with ARS:

● Confirmation–Indicates that a queued call is being serviced (trunk available to route call )

● Busy—Indicates that the called number is busy

●Reorder–Indicates that all trunks are busy, the ARS queue is full, or that ARS calling is denied.

●Preferred Route Tone—Five very short tones that indicate that your call has been queued for the preferred route.

Considerations

With ARS, users do not have tc worry about accessing a particular pooled facility to make a long distance call. The user simply dials the ARS access code and the desired number. The system then routes the call via the facility best suited for that call.

The following provides a summary of the ARS call routing controls provided by the feature:

● Emergency Numbers List: 911, a n d u p t o t h r e e c u s t o m e r - d e f i n e d , 7 - d i g i t numbers.

●Toll Call Allowed Lists: 1-4lists, 64 entries maximum between all lists. Entries may be 3-digit CO codes or 6-digit NPA plus CO codes. (Administrable for uses besides ARS)

● Station Toll Restriction Class: l-4 Classes (Administrable for users besides ARS)

●HNPA Exception List: 1-4Lists, each with an associated ARS Routing Pattern. 800 (64 in Vl) 3-digit CO codes entries maximum between all lists (eight of the entries may be 7-digit numbers.)

●NPA Routing Table: Entries may include every North American NPA (and Special Number NPAs in V2), each with an associated ARS Routing Pattern. All NPAs are assigned Routing Pattern #1 by default.

●FNPA Special Numbers List (VI only): Routes all “800”, “900”, and Telex 510, 610, 710, and 810 numbers via the local CO trunk group (not administerable)

●FNPA Exception List: One List with up to 32 eight-digit numbers. Each entry has an associated ARS Routing Pattern.

●Digit Translations Tables: One per trunk group (Vl and V2) or Virtual Facility (V2 only).

A	system can	have	up	to eight ARS Routing Patterns assigned. Each pattern can contain up
to	six routes	(three	per	subpattern).

Interactions

●Calling Restrictions: Outward Restriction and To1l Restriction, when

administered, prevent calls from routing via ARS. Pooled facility access restrictions do not apply. In fact, the recommended arrangement to ensure that users make maximum use of ARS is to block dial access to most trunk groups, so that users must dial the ARS access code to place calls.
