Denied Code Tables
Denied Code Tables are preprogrammed lists containing the first few digits (leading number) of telephone
numbers which may not be called. All outgoing CO line calls made by TRS level 2 through 6 users are
compared to at least one Denied Code Table, and when the leading number of a dialed telephone number
(not including the CO Line Access number) matches an entry found in the applicable table, the call is denied.
There are five Denied Code Tables. Each table applies to a corresponding TRS level as well as the level(s)
preceding it, as explained below.
