If a station does not have access, because of programmed restrictions, to a route that the ARS selects for it, the

system denies the dialing and causes an error tone to sound at the station. If the station does have access, ARS

routes calls from that station based on the routing information. If the call cannot be made on the line group first

selected by the routing, ARS will try the next route. Once again the route access is tested. This process is

repeated, up to a maximum of six times. Each route is programmed from least to most costly. The more costly

the route, the higher the access level needed to access it and the greater the chance that the station will be denied

access. If ARS selects a more costly route because the least costly one is busy, a station user receives a warning

tone when a call is attempted. Since this tone indicates that a more expensive line group was chosen by the

system, the station user should hang up and try again later. This warning tone feature is enabled through

programming.

Before automatic route selection can operate efficiently in a cost saving manner, the installer must group similar

lines together into line groups.

Each route in every route table contains costing information. The costing information includes two

programmable tiers of costing and a programmable surcharge amount. Even if a call is not routed through ARS,

(if the station user selects the line), the system still accesses this costing information to cost the call.

The installer can arrange the automatic route selection feature so that it modifies the dialed number by adding or

deleting digits until the number better fits the dialing needs of the selected route. Doing this results in situations

such as the following example:

Assume a station user dials 12025551212 (Washington D.C. area), and further assume that the system has an

FX line to the Washington D.C. area and ARS will route the call over it. ARS will delete the 1202 prefix and

only dial 5551212 because the FX line does not require the prefix numbers to complete the call. Field

maximum: 20 digits.

You can program the system for any one of three different dial tones that you will hear whenever you enter the

ARS access code. The ARS dial tone choices are:

•

Dial Tone 1: steady intercom dial tone (dual tones of 480 Hz + 620 Hz),

•

Dial Tone 2: same as dial tone 1 only preceded by three short tones (200 ms on, 200 ms off),

•

Dial Tone 3: steady simulated central office ring back tone (dual tones of 440 Hz + 480 Hz).

Automatic Route Selection For Speed Dials

The installer can arrange for the system to route the system speed dial and any personal speed dial numbers that

the user has programmed through the system’s automatic route selection feature (ARS).

ARS Access Per line Group

This feature allows the access code for any line group in the system to provide access to ARS. By default, the

line group 1 access code will provide ARS access when ARS is enabled. You can program this item on a line

group parameter.

ARS Delayed Dialtone

This feature adds a delay option for ARS Dialtone (Dial Tone 4). When the telephone user selects an

outside line, there is a 1 second delay before dial tone is presented to the caller. The dial tone frequency is

the same as the system intercom dial tone, but the delay gives the impression a “fresh” dial tone for

outbound dialing.
