Panasonic 524X07801B ARS/TRS Features

Section 700 - Operation Appendix A. ARS and TRS Operation

576-13-700 DBS 576 (USA), Revised 6/11/98 293

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 addi tion a wil d card (*) m ay 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 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 insta nce 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 deter mines an exact matc h, the system will de termine from this ta ble the number of di gits that

are to be dialed and the restriction TRS level. (There are two other entries in the Leading Digits Table - Route

Type and Route Number. These are not used for TRS-only operation.)

Note that TRS operation is a match then restrict feature. If there is no match, there is no restriction. Make

certain that there is a match. As a ca tch all, use the * wild card.

Note: With TRS is used in a system behind another PBX, the PBX access code does not have to be processe d

by TRS

If the Leading Digits Table contains a Pr ef i x I D , th e sy s t em will consider all appearan c es 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 deter mines an exact matc h, the system determi nes from this table t he number of digits that can

are expected to be dialed and the restriction TRS level. (There are two other entries in the Analyze Digits Table

- Route Type and Route Number. There are not used for TRS-only operation.)

ARS/TRS Features

When ARS is used in the DBS 576 system, TRS also operates.

These are the same features as for TRS (see above).

For each of the 50 TRS classes, a TRS Level o f 0-9 may be assigned. (This is not done on a Trunk group basis

since the ARS system determines the trunk group used.)

When a call is origi nated, this TRS va lue is used to dete rmine the originato r’s TRS level. From the dialed

digits, a restriction TRS level (0-8) is determined. If the origin ator’s TRS level does not exceed the restriction

TRS level, the call is restricted. The high er the or igi nator’s TRS level, the less the restriction. If the origi nat or’ s

TRS level is 0, no outside calls are allowed. If the originator’s TRS level is 9, all outside calls are allowed since

this will always exceed the restriction TRS value (maximum of 8).
