Automatic Route Selection1
ARS INTRODUCTION Automatic Route Selection (ARS) is a comprehensive and flexible on-line call routing scheme that you can customize from the programming terminal. ARS accommodates over 8000 call routing choices -- without a custom-ordered rate structure data base. Automatic Route Selection allows modifications to the routing choices to be made quickly and easily as the cost structure of the connected services change. ARS provides: Call Routing 3-digit (Area Code) and 6-digit (Area Code and Exchange) analysis can be applied to every number dialed. Dialing Translation (Special Dialing Instructions) Stored dialing instructions can be automatically executed when a route is chosen. . Time of Day Selection Route selection can be independently programmed according to the time of day/day of week. Hierarchical Class of Service Control Call route choices are allowed or denied based on an extension’s Class of Service. Forced Authorization Code Designated routes may require the user to enter an Authorization Code be- fore routing is allowed. This code is verifiable and is enforced by station Class of Service. Separate Routing For Operator Assisted, International and Equal Access Calls To provide unique control, separate routing instructions may be pro- grammed for Operator Assisted, International and Equal Access calls. Independently Programmed Restriction for Exchanges 976 and 555 Restriction for these exchanges is hierarchical according to an extension’s Class of Service.

DEFINITION OF TERMS Call Route Option The Call Route Option is a subset of the Selection Number and defines the routing of a call. The Call Route Option considers the maximum Class of Service permitted to access the route, assigns the route, and specifies the Dial Treatment that applies to the route selected. Each of the 64 Selection Numbers can have a total of 16 Call Route Options for each of the eight Rate Periods, for a system capacity of 8,192. Carrier The Carrier is the company which provides a service to which a call may be routed. Some typical Carriers are AT&T, MCI, GTE (US Sprint) and Western Union. Conflict Code/Conflict Area A Conflict Code is a local exchange code that uses 0 or 1 as the second digit. A Conflict Area is a dialing area (NPA) in which Conflict Codes ex- ist. Dial Treatment A Dial Treatment contains any special dialing instructions that are to be automatically performed when a call is redialed on the selected route. The ARS system accommodates a total of 15 programmable Dial Treatments. Each Call Route Option can be assigned one of 16 Dial Treatments. Equal Access Equal Access allows a primary carrier for long distance calls to be se- lected. When a user dials 1 + NPA + NNX + nnnn, the call will go out on the preselected primary carrier service. To manually dial toll calls on serv- ices other than the primary carrier, the user dials 10XXX + NPA + NNX + nnnn. Note that 10XXX is the equal access code to an alternate carrier. Equal Access capability is not provided by all telcos. Holiday For the purposes of Rate Period selection, Holidays are defined as New Year’s Day (January 1), Independence Day (July 4), Labor Day (the first Monday in September), Thanksgiving Day (the fourth Thursday in No- vember) and Christmas Day (December 25). Holidays nationally observed on days other than those listed above are not considered by ARS to be Holidays. Description DEFINITION OF TERMS Automatic Route Selection5
Local Address The Local Address is that portion of a telephone number that follows the NNX (local exchange). In the dialing format NPA + NNX + nnnn, the nnnn entries represent the Local Address. Non-Protected Code A Non-Protected Code is an exchange code in the home area code, which is also an exchange code in an adjacent area code, that can be dialed toll- free from some point in the home area. Protected Code A Protected Code is an exchange code, not used in the home area code, that is in an adjacent area code and can be dialed toll free from some point in the home area code. Rate Period For call cost structure purposes, each day of the week is divided into Rate Periods. ARS recognizes eight periods. A Rate Period can be from 30 min- utes to 24 hours in length and can be programmed to start and stop on the hour or half hour. Selection Number ARS is programmed to assign each call dialed to one of 64 Selection Num- bers. For each call dialed, ARS analyzes the time of day based on the Rate Periods programmed. ARS then routes the call on the preferred available Call Route Option programmed for the accessed Selection Number. Service Number A Service Number is a group of lines used for ARS and LCR routing. The lines within a Service Number should be the same type (e.g., WATS5, DDD). The system can have up to 10 Service Numbers, programmed in QL- SERVICE nn LINE NUMBER. Service Numbers are in addition to the Line Groups programmed in GROUP #9n LINE NUMBER. Service Numbers may overlap line groups, however, if desired. Description DEFINITION OF TERMS 6Automatic Route Selection
ABBREVIATIONS NNX1 NNX is an abbreviation for a local exchange. Valid local exchanges are 220-299 through 920-999. In a Conflict Area, valid NNXs may be any code 200 through 999. NPA1 NPA is an abbreviation for Area Code. Valid Area Codes are 200-219 through 900-919. Description ABBREVIATIONS Automatic Route Selection7 1As of January, 1995, the North American Numbering Plan may affect local exchanges and area codes in your region. For further information regarding the North American Numbering Plan, refer to NANP Compatibility in the Feature section of the ONYX Feature and Terminal Programming Manual (P/N N1850SWG04).

The 6-Digit Table Automatic Route Selection (Figure 1-1) examines the digits a user dials and determines which of the 64 available Selection Numbers should be used for the call. If the user dials an NPA, ARS looks first at the 6-digit ta- ble for routing instructions. The six digit table is a series of NNX lists as- signed to each NPA. If the NPA a user dials is programmed into the 6-digit table, and the NNX dialed is in one of the NNX lists for the NPA, ARS routes the call according to the 6-digit table Match Selection Number. If the NPA is in the 6-digit table and the NNX is not in one of the NNX lists, ARS routes the call to the Default Selection Number. The 3-Digit Table If the NPA the user dials is not in the 6-digit table, or the user dials an NNX without an NPA, ARS looks at the 3-digit table. If the NNX or NPA is in the 3-digit table, ARS routes the call according to the 3-digit table Se- lection Number. If the NNX or NPA is not in the list, the call is placed on service # 1. Rate Periods Once ARS chooses a Selection Number, Automatic Route Selection exam- ines the time of day and day of week. ARS then selects the current rate pe- riod using the Rate Period table. You can program a maximum of eight Rate Periods. Call Route Options ARS provides up to 16 Call Route Options for each Rate Period in a selec- tion number. A Call Route Option defines: •The maximum Class of Service permitted to use the option •The service # accessed if ARS chooses the option •The Dial Treatment instructions imposed on the initial number dialed You program the Call Route Options into a list (from 1 - 16) for each Se- lection Number and Rate Period. Construct the list in order of routing pref- erence. The option at the top of the list is the most-preferred. The option at the bottom of the list is the least-preferred. If the most-preferred Call Route Option is busy, ARS routes the call to the next-most-preferred op- tion. If all the Call Route Options available to the extension are busy, the call cannot go through. Description ARS OVERVIEW Automatic Route Selection9
