TRS Features

TRS Class Features
Each trunk and extension 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 0-9 may 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.
