TRS (Call Barring ) classes are set on an extension and trunk basis. Up to 50 TRS (Call 
Barring) classes can be assigned.

•

Each TRS (Call Barring) class is then assigned to a TRS level. This level is used as the basis 
for allowing or restricting calls.

•

There are 10 TRS (Call Barring ) levels available: 0 denies all calls, 1-8 may be partially 
restrictive per assignments, and 9 allows all calls.

TRS (Call Barring) can restrict the number of digits dialled (1 to 20 digits limit or no limit).

•

TRS (Call Barring) can restrict the use of System Speed Dials (SSDs) for out dealing on a 
TRS (Call Barring) class basis; either no system speed dials or limit the range of SSDs.

•

TRS (Call Barring) can restrict the use of the star (*) or pound (#) digits on a TRS (Call 
Barring) class basis.

The following calling restrictions are also available:

The dialling restrictions included in this feature help prevent unauthorized outgoing calls. It is

selects an open trunk from the group.
