ARS Worksheet
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)
Keep in mind that for 10-digit toll calls, callers must dial 1 before dialing the area
code, even if they don't normally need to dial a prefix to make a toll call.

Planning Form Instructions
1. Review Form 2c, System Numbering: Line/Trunk Jacks, for the types of
lines/trunks available.
2. Record the number of exchanges in the local calling area in the blank at the
top of Form 3e, Automatic Route Selection Worksheet. If you are not sure
how many exchanges there are, consult the telephone directory.
3. Enter the number of each of the trunk pools (factory setting is 70 or
(890 899) in the Trunk Pool No. column.
Some trunk pools, such as in-state WATS trunk pools, can be used for both
toll and local calls. (Note that with ARS a local call is any call that doesn't
require dialing a 1.)
If you expect people to use a particular trunk pool for both toll and local calls,
enter the number of that trunk pool in the worksheet twice, and note the rea-
son.
4. For each trunk pool number entered:
a.
b.
provides a sample of a completed ARS worksheet.
In the Trunk Type column, record the type of trunk (local, FX,
regional WATS, and so on) that is in the pool.
Under the Type of Dial heading, check the appropriate column (Toll
or Local) for the type of call that should be dialed on each trunk pool:
Toll. Any call that has a series of digits beginning with a 1,
followed by an exchange or area code.
Local. Any call that is not a toll call. This includes the
seven-digit dialed numbers required in most areas.
