The circuit set parameters specify the characteristics of each of the circuit sets to be managed by the TUP layer, including the circuit identification codes (CICs) and destination point code (DPC) at the other end of the circuits. One entry is made for each circuit set. Any set can be designated as a predefined group by adding a group number to this definition. A predefined group can more easily be reset, blocked, and unblocked with the TUP functions or by the network.

This number is used by the application and the TUP layer to identify circuits, but has no meaning to the far exchange. |
CIC |
0 |
