Automatic Route Selection (F-Route)
• Description
Automatic Route Selection (ARS) provides call routing and digit translation based on
the digits a user dials. ARS consists of look up tables that compare the dialled digits
and decide which translation table should be used. The decision can optionally be
dependant on time and day of the week. The translation table will then delete and/or
add digits select the trunk group and seize the outgoing trunk.
ARS Feature Summary
•
Basic ARS Operation
When a user places an outside call, ARS analyses the digits dialled
and assigns one of 64 Selection Numbers to the call. The Selection
Number chosen depends on which digits the user dialled. ARS then
checks the time of the day, the day of the week and the extension’s
ARS Class of Service. Based on these call routing options, ARS
selects a trunk group for the call and imposes the Dial Treatment
instructions (if any).
•
Call Routing
ARS can apply up to 24-digit analysis to every number dialled. For pro-
gramming, ARS provides separate 8-digit and 24 digit tables. Each
table can have up to 250 numbers.
•
Dialling Translation (Special Dialling Instructions)
ARS can automatically execute stored dialling instructions (called Dial
Treatments) when it chooses a route for a call. The system allows up
to 15 Dial Treatments. The Dial Treatments can:
- Automatically insert or delete a leading 1
- Insert or delete and area code (NPA)
- Add digits (such as a dial-OCC number), pauses and waits to the dial-
ling sequence
- Require the user to enter an authorisation code when placing a call
(see Forced Authorisation Code below)
•
Time of Day Selection
For routing purposes, ARS provides ten different day selections (called
Time Schedule Patterns). Each Time Schedule Pattern can provide up
to 20 time intervals which are assigned to a day of the week (Monday-
Friday, Saturday, Sunday or Holiday).
•
Hierarchical Class of Service Control
ARS allows or denies call route choices based on an extension’s ARS
1
Class of Service. This allows lower Classes of Service (e.g., 1) to
access routes unavailable to higher Classes of Service (e.g., 16). The
system provides up to 16 (0=unrestricted, 1-16) ARS Classes of Ser-
vice.

Use Program 26-04-01 to assign an extension’s ARS Class of Service. An
extension’s Class of Service (set in Programs 20-xx has not effect on ARS
routing choices.
