Conditions
CAUTION
The software contained in the TRS feature to allow user access to the network must be upgraded to
recognize newly established network area codes and exchange codes as they are placed into service.
Failure to upgrade the on-premise PBXs or peripheral equipment to recognize the new codes as they
are established will restrict the customer and the users of the PBX from gaining access to the network
and to these codes.
KEEP THE SOFTWARE UP TO DATE WITH THE LATEST DATA.
•
TRS checks are performed for all calls made by:
–
Any CO line access (Idle Line Access, Trunk Group Access, S-CO Line Access)
–

•
The PBX can also be programmed to perform a TRS check for numbers that contain non-digits (
By default, the PBX ignores ("No Check") any non-digits that are dialed, which is useful in preventing
unauthorized calls which could possibly be made using certain telephone company exchanges.

ARS
If ARS is applied to a dialed number, TRS will check the user-dialed number, not the modified number
produced by ARS. You do not need to program ARS-modified numbers in any of the TRS Tables.
Additionally, when using ARS, TRS will ignore the Host PBX Access code or Special Carrier Access
code.
•
Dialing Digit Restriction during Conversation
TRS can also limit the number of digits which may be dialed by an extension user while the user is
engaged on a received CO line call. If the number of dialed digits exceeds the limit, the line will be
disconnected.

digit time expires without the TRS check being completed.
