Appendix A. ARS and TRS Operation
Introduction
This appendix provides an overview of the Toll Restriction Service (TRS) and Automatic 
Route Selection (ARS) features that are available with the DBS 576 PBX. 
• TRS provides the ability to block selected outgoing calls while allowing others.
• ARS  automatically finds the lowest cost way to send out a call. This feature is 
sometimes called Least Cost Routing (LCR).
With the DBS 576 system, it is possible to utilize TRS without ARS (called TRS) or to utilize 
both TRS and ARS together (called ARS/TRS or simply ARS).
Once TRS is set up, it is automatic. Whenever a call is originated, the TRS tables are checked 
to see if the call is restricted or not. This restriction is based on the originator and the number 
dialed. Separate TRS classes are assigned for Day mode and Night mode.
ARS operates when ARS is enabled and the caller dials the first MCO Access Number 
(usually 9). Direct trunk access and the second to fifth MCO Access numbers (usually 81 to 
84) do not utilize ARS. 
ARS use may be required based on the extension originating the call. This is enabled by the 
Forced ARS extension setting.
The ARS feature is exceptionally flexible, depending on the implementation plan. Call 
routing can consider the day of the year, day of the week, time of day, the originating 
extension or trunk and the number dialed. If the preferred route is busy, up to 4 additional 
routes can be considered. When all trunks in a call route are busy, the call can optionally be 
queued to continue trying all trunks while moving to the additional routes. 
Once the trunk group is selected, prefix digits can be deleted and digits added. In addition, 
digits can be added as a suffix.
A high cost toll call warning can also be issued before connecting to a high cost trunk, giving 
the caller an opportunity to terminate the call attempt before a higher cost connection is 
established.
Both TRS and ARS/TRS utilize various tables that are linked together. These tables together 
determine the TRS and ARS/TRS operation. Data must be collected determining the 
customer’s needs, requirements and facilities. Then the data must be analyzed to organize a 
TRS or ARS plan. This plan must then be implemented using the appropriate TRS or ARS/
TRS tables.

Section 700 - Operation
Detailed Description
This section provides a description of the TRS and ARS options on the DBS 576 PBX.
TRS Features
TRS Class Features
Each trunk and extension is assigned to one of 50 TRS classes. Each TRS class is assigned a 
Day TRS level and a Night TRS level for each Trunk group. This assigned origination party 
TRS level is compared to the restriction TRS Level determined by the dialed number. If the 
Origination Party TRS level is not higher than the restriction party TRS level, the call is 
denied. 
In addition, each TRS class is assigned settings such as Outgoing Dial Digit Restriction, 
Incoming Dialing Restriction, Outgoing SSD Dialing Restriction, and * and # Dialing 
Restriction.
Outgoing Dialed Digit Maximum
This TRS Class-based parameter sets the maximum number of digits that can be dialed for 
outgoing calls in a TRS Class. The maximum number of digits can be set from 0-20.  When 
set to 0 (default), there is no restriction.
Dialing Restriction During Inbound Calls
Determines whether dialing during an incoming call is restricted on trunks in a TRS Class.
TRS Override on SSD Dialing
Determines whether SSD dialing will override TRS on extensions for a TRS Class.
Star (*) and Pound (#) Dialing Restriction
Determines if the * or # key can be used in dialing for a TRS Class. 
TRS Level for Non-ARS Routing
For each of the 50 TRS classes, an originator’s TRS level of 0-9 may be assigned for each 
possible trunk group. When a call is originated on a particular trunk group, this value is used 
to determine the originator’s TRS level. From the dialed digits, a restriction TRS level (0-8) 
is determined. If the originator’s TRS level does not exceed the restriction TRS level, the call 
is restricted. The higher the originator’s TRS level, the less the restriction. If the originator’s 
TRS level is 0, no outside calls are allowed. If the originator’s TRS level is 9, all outside calls 
are allowed since this always exceeds the restriction TRS value which has a maximum value 
of 8.
Dialing Analysis
When a trunk is accessed, the dialed digits can be analyzed to determine if the call will be toll 
restricted.
