The command is used to control and restrict extension/operator calls to network routes. Each extension is assigned a TCM value. In addition each route choice defined for a given destination in the network is assigned a TCM value too. A call setup is allowed if TCM value for call originator is higher or equal to that of chosen route.

The lowest restriction is level 7, the highest restriction is level 0.
