FF2: T1-CO Lines

•

The T1 Line proivdes trunk signaling modes for Loop Start, Ground Start, and E&M.

•

Also see Class of Service - T1 Trunk Ring Back Service Tone on p. 3-16 for more information on 

T1 Line features.

Toll Restriction Service (TRS) allows access levels, including the prohibition of long distance calls or 

after-hours calls, to be assigned to specific extensions or CO lines. This minimizes non-business 

related calls and reduces phone bills by only allowing long distance calls over designated lines.

TRS can be used in conjunction with Automatic Route Selection (ARS). 

•

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

•

Each TRS class is then assigned to a TRS level. This level is used as the basis for allowing or 

restricting calls.

•

There are 10 TRS levels available: 0 denies all calls, 1-8 may be partially restrictive per 

assignments, and 9 allows all calls.

•

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

•

TRS can restrict the use of System Speed Dials (SSDs) for out dialing on a TRS class basis; 

either no system speed dials or limit the range of SSDs.

•

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

The following calling restrictions are also available:

•

Forced ARS Restriction (The ARS feature controls outside calls.)

•

N/A

•

N/A

•

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

possible; however, to program your System to allow SSD to override TRS.

•
