A-8
DBS 576HD (USA) issued September 2001
576HD-50-700
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.
