Figure A-10. Example Carrier C Simplified WATS Service Bands for Atlanta 
In this very simplified WATS example, the higher the Out-WATS band, the longer distance the call and therefore the higher cost the call. 
However, calls using Out-WATS are always less expensive than other long distance choices (except for the FX line calls to Birming-
ham)  Note that if alternative carriers were less expensive for some areas than the Out-WATS service, then the area codes would have to 
be considered in choosing the route.

Figure A-11. Example Foreign Exchange Lines From Atlanta to Birmingham
In this case we have two Foreign Exchange (FX) lines to a Birmingham Central Office Exchange. Using these lines are like dialing 
directly from the Birmingham exchange.  We pay a flat fee for the FX line. There is no additional charge for calls to Birmingham. 
For this example, there are three office exchange numbers in Birmingham, 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 314.
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 315.

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.

3.  From the User Needs and Tenant Trunk Groups Worksheets, ARS levels are determined. This list is 
created by reviewing the different calling needs and assigning the least cost access levels to the lowest 
ARS level and working up to the highest cost ARS level.

4.  Next the Origination TRS and ARS level and queuing point enable/disable operation is determined for 
each class.
Using Table 7, “Example - User Needs Worksheet,” on page 314, each unique origination class is listed. 
Using Table 9, “Example - Origination TRS Level Plan,” on page 316 the TRS Level is determined for 
each class. Using Table 8, “Example - MCO Tenant/Trunk Groups Worksheet,” on page 315 and Table 10, 
“Example - Origination ARS Level Plan,” on page 317, the ARS level is determined for each class.
In this example, we enable Queuing Point so that the system will continuously check for the availability of 
a lower cost trunk before selecting a higher cost trunk.
Table A-11.  Example - Origination TRS/ARS Class to Level Worksheet
Calls are screened by examining the initial digits dialed. A * is available as a wild card. This represents 
any single digit 1 to 9. 
When prefix dial is being considered by the system, the system looks for the longest exact match first. The 
system considers a wildcard last.

5.  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 considers 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 needed are 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 and Prefix ID 2 for any dialed number that begins with 0. The remaining digits are analyzed 
in the Analyze Digits Table.
From Table 7, “Example - User Needs Worksheet,” on page 314 and Table 9, “Example - Origination TRS 
Level Plan,” on page 316, the restriction levels are determined for each type of dialed call.
We determine the Route Type depending on the type of call. If the time and or day impacts the cost, then 
the time list is used. If the time is not a factor, but multiple trunk groups could be used, then the Route List 
is used. If a specific trunk should be used, then we directly reference the Route Table.

6.  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.
