TRS Features

TRS Class Features

Each trunk and extension in the DBS 576 PBX is assigned to one of 50 TRS classes. Each TRS class is assigned a Day TRS level and a Night TRS level for each Trunk group. This assigned origination party TRS level is compared to the restriction TRS Level determined by the dialed number. If the Origination Party TRS level is not higher than the restriction party TRS level, the call is denied.

In addition, each TRS class is assigned settings such as Outgoing Dial Digit Restriction, Incoming Dialing Restriction, Outgoing SSD Dialing Restriction, and * and # Dialing Restriction.

Outgoing Dialed Digit Maximum

This TRS Class-based parameter sets the maximum number of digits that can be dialed for outgoing calls in a TRS Class. The maximum number of digits can be set from 0-20. When set to 0 (default), there is no restriction.

Dialing Restriction During Inbound Calls

Determines whether dialing during an incoming call is restricted on trunks in a TRS Class.

TRS Override on SSD Dialing

Determines whether SSD dialing will override TRS on extensions for a TRS Class.

Star (*) and Pound (#) Dialing Restriction

Determines if the * or # key can be used in dialing for a TRS Class.

TRS Level for Non-ARS Routing

For each of the 50 TRS classes, an originator’s TRS level of 0-9may be assigned for each possible trunk group. When a call is originated on a particular trunk group, this value is used to determine the originator’s TRS level. From the dialed digits, a restriction TRS level ( 0-8) is determined. If the originator’s TRS level does not exceed the restriction TRS level, the call is restricted. The higher the originator’s TRS level, the less the restriction. If the originator’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 always exceeds the restriction TRS value which has a maximum value of 8.

Dialing Analysis

When a trunk is accessed, the dialed digits can be analyzed to determine if the call will be toll restricted.
