Appendix A. ARS and TRS 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 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 Atlanta based XYZ Department Store 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 Birmingham, Alabama where a sister store and many suppliers are located

restrict special calling numbers (976, 1900, outside operator, etc.)

911 always allowed

40 general office phones

long distance allowed during day mode

restrict special calling numbers (976, 1900, outside operator, etc.)

911 always allowed

10 purchaser/buyer telephones

no time restriction
