Basic Ars Operation; Class Of Service Option Allows Outgoing Calls To Not Follow Access Map; Class Of Service Matching - NEC UNIVERGE SV9100 Features And Specifications

Basic ARS Operation

When a user places an outside call, ARS analyzes the digits dialed and assigns one of 2000 Selection
Numbers to the call. The Selection Number chosen depends on which digits the user dialed. ARS then
checks the time of day, the day of week and the extension 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).

Class of Service Option Allows Outgoing Calls to Not Follow Access Map

Using this option allows a Class of Service to be set so that ARS does not follow the trunk access map
settings (Program 14-07-01 and Program 15-06-01). The feature allows an extension user to have CO
line keys on their telephone which allow incoming access only. The user has only outgoing access on the
CO lines when using ARS to place a call.

Class of Service Matching

With the ARS Class of Service Match Access feature, you can determine whether the system should
allow a call based on the COS assigned to the Dial Analysis Table (Program 26-02). This change can be
used to create a tenant-like application. It then uses the trunk group defined in the Additional Entry in
Program 26-02-03 to place the outgoing call.
When this feature is enabled, the calls are routed in sequential order, and are allowed if the Class of
Service for the trunk group matches.
For this feature, Program 26-01-06: Automatic Route Selection Service, COS Match Access is
used.
