Appendix A. ARS and TRS Operation Section 700 - Operation
ARS Configuration and Operation
This section provides the following:
• An overview of ARS.
• An example ARS configuration.
• Worksheets for planning and implementing an ARS plan.
ARS/TRS Programming/Operation Overview
The purpose of TRS is to restrict outside call origination based on the dialed number and the originator. The
purpose of ARS is to automatically select the lowest cost route available for a call based on the dialed number.
The system allows separate TRS operation or TRS operation concurrent with ARS operation.
TRS-only operation is described in the previous section of this appendix. The TRS portion of ARS/TRS works
in the same manner.
As shown in Figure A-5 “ARS/TRS Operation” found at the end of this appendix, up to 50 TRS/ARS Class
Settings are assigned. When a call is originated, several general settings for the originator are always
considered:
• Digit Restriction - This is the maximum number of digits that can be dialed.
• Incoming Dialing Restriction - If this is enable, an outside call cannot be originated during an
incoming call.
• Outgoing SSD Dialing Restriction - This determines if SSD dialing is allowed or not.
• Star (*) and Pound (#) Dialing Restriction. - This determines if the * and # digits can be outdialed.
When a call is originated, the system determines the TRS/ARS Class for the originator from either the
Extension Class Assignments or the Trunk Class Assignments. It then determines the originator TRS level and
originator TRS level from the TRS/ARS Class Assignments. In addition, the Queuing Point continue parameter
setting is considered.
When the call is dialed, the system collects the digits and compares the leading digits to the leading digits table
entry. The system looks for the longest available exact match. A * may be entered as a wild card for any digit
position.
If an exact match is found, the system looks to see if there is a prefix ID. If so, it will jump to the analyze digits
table. If not, the system will compare the entered TRS Restriction value to the call originator’s assigned TRS
level. If the Restriction value is equal to or greater than the originator’s TRS level, the call is denied. Otherwise,
the Route Type and associated Pattern # are determined and the system jumps there.
