Appendix A. ARS and TRS Operation Section 700 - Operation

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 0-9where the higher number allows more calling access.

Queuing Point

The Route List provides up to 5 route possibilities for handling a call. Each route is considered in a sequential order. When the Queuing Point is set to operate, the system will search all previously considered routes and then the current route for an available trunk for the Queuing time period.

Dialing Analysis

When ARS is active, the dialed digits can be analyzed to determine if the call is toll restricted and what type of routing the call will follow.

Leading Digits Table

The leading digits table considers the initial dialed digits in determining the restriction TRS level and ARS routing.

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 considers the longest exact match first. For instance, the prefix string 404 match would be followed before 40.

A wild card is always considered last. For instance if 911 were dialed and both 911 and *11 were prefix strings, the 911 would be followed.

If additional digits need to be considered, a prefix ID can be used to cross-reference the Analyze Digits Table.

Once the system determines an exact match, the system will determine from this table the number of digits that are expected to be dialed and the restriction TRS level.

If the TRS level allows the call to proceed, then the route type and its associated pattern number (entry index number) are followed. There are three possible route types; the Route Table, the Route List Table and the Time List Table.

Analyze Digits Table

If the Leading Digits Table contains a Prefix ID, the system considers all appearances of this Prefix ID to look for an exact match. Up to 8 digits are considered (in addition to the prefix dial digits).

Once the system determines an exact match, the system determines from this table the number of digits expected to be dialed and the restriction TRS level.

If the TRS level allows the call to proceed, then the route type and its associated pattern number (entry index number) are followed. There are three possible route types; the Route Table, the Route List Table and the Time List Table.
