3.  Next the Origination TRS Level is determined for each Trunk group per class.
Using Table 1, “Example - User Needs Worksheet,” on page 10, each unique origination class is 
determined. Then using Table 3, “Example - Origination TRS Level Plan,” on page 12 the TRS level is 
determined for each class. (If there were multiple trunk groups available, a TRS level would be assigned 
for each trunk group for each class.)

4.  Calls are screened by first considering the initial digits dialed. In this case, the first Prefix Dialed entry is a 
1. This will look at any number that starts with 1. A * is available as a wild card. This represents any single 
digit 1-9. 
When prefix dial is being considered by the system, the system looks for the longest exact match first. The 
system will consider a wildcard last. For instance, 911 is considered before *11 or even *. Notice also in 
this example there are multiple entries that begin with 9.
If the leading digits are not enough to determine the handling of the call, then additional digits can be 
considered by entering a Prefix ID that references entries in the Analyze Digits Table. Otherwise, the 
Prefix ID is left blank and the additional items are considered.
In this example, we cross reference Prefix ID 1 in the Analyze Digits Table for any dialed number that 
begins with 1. The remaining digits are analyzed in the Analyze Digits Table.
From Table 1, “Example - User Needs Worksheet,” on page 10 and Table 3, “Example - Origination TRS 
Level Plan,” on page 12, the restriction levels are determined for each type of dialed call.
Route Type and Route Pattern Number are not used with TRS-only operation.

5.  In this case, Prefix ID 1 links calls that have a dialed prefix of 1. Several entries are made to determine the 
restriction TRS level and the Route Type. The call originator must have a Origination TRS Level 
exceeding 1 for the call to be allowed. If any other analyze digits are dialed this would be covered by the 
three * wildcards (***). In this case; the call originator must have a TRS level exceeding 2 for the call to 
be allowed.

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 enabled, 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.

If the analyze digits table is referenced by a prefix ID, the system will consider at all entries with the prefix ID 
and analyze any additional digits dialed. The system looks for the longest exact match. If there is an exact 
match, the system compares 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.
Three route types are available. These include the Routing Table (a direct trunk group selection), the Route List 
Table (a route priority consideration), and the Time List Table (selects a route list based on date, day of the 
week, and time of day).
The simplest call routing method is the Route Table. This determines a trunk group to use and, if programmed, 
a digits modification pattern to use. Up to 24 prefix digits may be deleted, up to 10 prefix digits can be added 
and up to 10 suffix digits may be added.
If multiple trunk groups are to be considered for the call, the Route List Table is used. This table consists of up 
to 5 possible routes and an associated ARS level required. If the ARS level for the first priority route is equal to 
or less than the ARS level associated with the call originator, then the listed route will be tried. If the first listed 
Route Table trunk group has no available trunks busy, then the next priority route is considered. If Queuing 
Point is set to continue, then the first priority trunks are retried first before trying to a next priority route. If the 
Warning Tone is enabled, then before a call is connected to a found trunk, a warning tone is sounded to allow 
the caller to hang up before the more expensive trunks are used.
If time of day, day of week and day of the year need be considered in routing the call, then the Time List Table 
should be referenced first. The Time List Table allows up to 50 patterns to be entered. Each pattern can specify 
up to 5 route list patterns to used based on the current time of day.
Up to four time list tables may be used. The referenced time list table is determined by the Special Day Table or 
the Day of Week Table. This is useful when rates change for certain days (such as weekend rates versus 
weekday rates).
Example ARS Configuration
As an example of setting up ARS, assume that XYZ Department Store is based in City A and is using the DBS 
576 PBX.
Situation 
This example installation has the following considerations:
• 75 retail floor store phones
•  restricted to local telephone use only except for 1800, 1888 and calls to another city where a 
sister store and many suppliers are located
•  restrict special calling numbers (976, 1900, outside operator, etc.)
•  public emergency numbers allowed
• 40 general office phones
•  long distance allowed during day mode
•  restrict special calling numbers (976, 1900, outside operator, etc.)
•  public emergency numbers allowed
• 10 purchaser/buyer telephones
•  no time restriction

Section 700 - Operation
•  restrict special calling numbers (976, 1900, outside operator, etc.)
•  public emergency numbers allowed
• 25 executive office telephones
•  no time restriction
•  no calling restrictions
• 2 attendant group phones
•  no restrictions during the day
•  local calls only at night to prevent abuse
• 7 warehouse phones
•  extension and public emergency numbers allowed
• Trunks 1-24 are in trunk group 1 and are to the local CO (exchange line) for local calls. In addition, long 
distance carriers are accessed using these trunks by dialing the equal access codes. Long distance carrier 
A (equal access code 101XXXX) is the least expensive carrier during the weekday times of 8 to 6. Long 
distance carrier B is the least expensive long distance carrier during nights, weekends, and holidays.
• Trunks 25 and 26 are in trunk group 2 and are toll-free out-going trunks from Long Distance Carrier C. 
These trunks are less expensive than either of the other long distance carrier lines.
• Trunks 27 and 28 are Foreign Exchange lines to a central office exchange in City B where a sister store 
and several suppliers are located. These trunks are always preferred for any call to City B area code  
with exchanges 555, 556, and 557.

Figure A-5.  Example Foreign Exchange Lines From City A to City B
In this case we have two Foreign Exchange (FX) lines to a City B Central Office Exchange. Using these lines are like dialing directly 
from the City B exchange.  We pay a flat fee for the FX line. There is no additional charge for calls to City B. 
For this example, there are three office exchange numbers in City B (555, 556, and 557) that we want to be able to call that are local 
calls. There are no other exchanges that begin with 55X.
Implementation
The configuration of this system is described in the following steps: 
1.  The system needs are listed in Table 7, “Example - User Needs Worksheet,” on page 23.
Most of the information is straight forward. The Day TRS and Night TRS Classes are determined by 
assigning consecutive Class numbers to each unique calling need. When a duplicate need is encountered, 
the same class number is assigned.
The system trunk equipment is listed in Table 8, “Example - MCO Tenant/Trunk Groups Worksheet,” on 
page 24.
