Leading Digits Table
The leading digits table considers the initial dialed digits in determining the restriction TRS level. 
Up to 10 digits can be considered. The digits may be any number 0, 1-9. In addition a wild card (*) may be used 
to occupy any digit position. For instance *11 would consider the numbers 011, 111, 211, 311, 411, 511, 611, 
711, 811, 911. 
When considering the prefix string, the system will always consider...

ARS Level
An ARS level is also assigned to each of the 50 TRS classes. This originator’s ARS value is used to determine 
if the caller can proceed to use a particular priority route based on the associated ARS requirement in the Route 
List (described later). The originator’s ARS value may be 0-9 where the higher number allows more calling 
access.
Queuing Point
The Route List provides up to 5 route possibilities for handling a...

Time List Table
Time List Table is used when the time of day, the day of week or the date affects the desired route. The Time 
List Table allows up to 50 patterns to be entered. Each pattern may specify up to five 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...

TRS Programming/Operation Overview
The purpose of TRS is to restrict outside call origination based on the number dialed and the originator.
As shown in Figure A-4 TRS Operation (Non-ARS) at the end of this appendix, up to 50 TRS Classes 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....

Section 700 - Operation
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 will look 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...

Implementation
The configuration of this system is described in the following steps: 
1.  The system needs are listed in Table 1, “Example - User Needs Worksheet,” on page 10.
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...

2.  From the User Needs and Tenant Trunk Groups Worksheets, TRS levels are determined. This list is 
created by reviewing the different calling needs and assigning the most restrictions to the lowest TRS level 
and working up to the least restriction level.
