Solution: In this case, number string '022' should be programmed in one of the locations of the allowed list and
should be assigned to station 21. Similarly, station 21 should not be allowed any other long distance call, hence the
default denied list 4 (which is already assigned to it) will serve the required purpose.
One such allowed and a denied list should also be assigned to the station for the locked condition.
Once the station has been locked, the station user can make calls as per the allowed and denied lists assigned to
the station for the locked condition. This is called Dynamic Toll Control.
• Allowed list 0 and Denied list 0 are assigned in locked condition by default.
• Default Allowed list for Day and Night is '2' whereas default Denied list for Day and Night is '4'.
