Automatic Route Selection (Ars); Ars Feature Summary - NEC UNIVERGE SV9100 Features And Specifications

Automatic Route Selection (ARS)

Description
Automatic Route Selection (ARS) (ARS) provides call routing and call restriction based on the digits a
user dials. ARS gives the system the most cost-effective use of the connected long distance carriers.
ARS is an on-line call routing program that you can customize (like other system options) from a display
telephone. ARS accommodates 2000 call routing choices – without a custom-ordered rate structure
database. With ARS, you can modify the system routing choices quickly and easily. This is often
necessary in the telecommunications world of today where the cost structure and service choices
frequently change.
The ARS feature can add or delete digits and route calls according to predetermined levels. When
UNIVERGE SV9100 systems are networked together by Tie Lines or K-CCIS, the networked systems
can be called by a system number and a user extension number, just an extension number, or by using
a trunk access code.

ARS Feature Summary

ARS provides:
Call Routing
ARS can apply up to 24-digit analysis to every number dialed. For programming, ARS provides
separate 8-digit and 24-digit tables. Each table can have up to 250 numbers.
Dialing Translation (Special Dialing Instructions)
ARS can automatically execute stored dialing instructions (called Dial Treatments) when it chooses
a route for a call. The system allows up to 15 Dial Treatments. The Dial Treatments can:
Insert or delete an area code (NPA)
Add digits (such as a dial-up OCC number), pauses and waits to the dialing sequence
Require the user to enter an authorization code when placing a call (refer to Program 44-03)
Time of Day Selection
For routing, ARS provides 10 different day selections (called Time Schedule Patterns). Each Time
Schedule Pattern can provide up to 20 time intervals which are assigned to one of the eight day/
night modes. The Time Schedule Patterns are then 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 ARS 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 Service.
Separate Routing for Selected Call Types
To provide unique control, you can program separate routing instructions for:
Directory assistance (411, 1411 and 555) calls
Emergency (911) calls
Separate Routing for Equal Access (1010XXX) Calls
Choose different routing for directly-dialed (1010XXX + 1) and operator-assisted (1010XXX + 0)
Equal Access calls.
