Automatic Route Selection

■
Set up the subpatterns for the table. In doing so, you may wish to check
with the remote system manager to ensure that routing will stipulate the
most cost-effective timing based on the rates at the remote location. If the
remote system is in a different time zone from your own, you may need to
take this into consideration as well.

■
Assign each tandem and/or tie trunk pool to an ARS table.
.
■
Assign appropriate Facility Restriction Levels to the routes and to the
extensions that will use the private network lines. Factory settings restrict
toll calls. See
‘‘Facility Restriction Level’’ on page 3-558
and
Restriction Level for Extensions’’ on page 3-334
, respectively.
■
Assign absorbed and other (added) digits as required by the final
destination. The local ARS feature adds (prepends) the ARS access code
of the remote system. At the remote system, digit absorption may be
needed. For example, if local callers are in the 908 area code but the
private network lines are connected to a system in the 617 area code,
callers might dial
916175551212
, where
9
is the local ARS access code.
At the remote system, because the call would be a local call, the absorbed
digits would be
1617.

SECURITY ALERT:
In Release 6.0 and later systems, do not place remote ARS access codes in
the non-local dial plan by specifying, for example, a non-local extension
range such as 9000–9050 when the remote ARS access code is 9. Doing
so allows DID callers to make outside calls through the remote switch and
may allow transferring of outside callers to outside dial tone on a remote
switch, possibly resulting in toll fraud.
1 + 7-Digit Dialing Requirements
3
Use this procedure for calls placed within the same (home) area code as the
system. The procedure allows you to specify whether or not the local telephone
company requires a 1 to precede the 7-digit number. The two available settings
are:
■
Within Area Code. Requires that a 1 plus a 7-digit number must be dialed;
the system checks the 1 plus 7-digit tables for routing.
■
Not within Area Code. Does not require that a 1 precede the 7-digit
number (the system does this automatically).
