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 and
890 899) in the Trunk Pool No. column.
NOTES:
4. For each trunk pool number entered:
a.
b.
provides a sample of a completed ARS worksheet.
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
does not 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 reason.
In the Trunk Type column, record the type of trunk (local, FX,
network, regional WATS, and so on) that is in the pool.
Under the Type of Dial heading, check the appropriate column
(Local, Toll, or Network) 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.
Network. Any call that will be routed to a non-local switch.
