Appendix A. ARS and TRS Operation

Section 700 - Operation

If the analyze digits table is referenced by a Prefix ID, the system will consider at all entries with the Prefix ID and analyze any additional digits dialed. The system will look for the longest exact match. If there is an exact match, the system compares the entered TRS Restriction value to the call originator’s assigned TRS level. If the Restriction value is equal to or greater than the originator’s TRS level, the call is denied. Otherwise, the call is allowed to proceed.
