• TRS checks are performed for all calls made by:
– Any CO line access (Idle Line Access, CO Line Group Access, S-CO Line
Access)
– Automatic Route Selection (ARS)
• The PBX can also be programmed to perform a TRS check for numbers that contain non-
digits ( or #). 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.
• TRS can also be programmed to check digits that are dialed after External Feature
Access, such as when trying to transfer a call to an outside party. (
Feature Access (EFA))
• Host PBX Access Code/Special Carrier Access Code
TRS checks can be carried out on telephone numbers dialed using a Host PBX Access
code ( 1.5.4.6 Host PBX Access Code (Access Code to the Telephone Company from
a Host PBX)) or Special Carrier Access code (

• 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.
• When one of the following features is used, the TRS level of the extension can be
temporarily changed. If two or more of these features are used simultaneously (Dial Tone
Transfer is used while the extension is locked, for example), the TRS level of the feature
with the highest priority is applied for the duration of the call. The numbers below (1
through 4) indicate the priority of each feature, with 1 having the highest priority, and 4
having the lowest.
