Abstract
A call restriction system for an ATM exchange reduces the load on the call control processor and achieves a step-wise variation in the degree of call restriction in response to the degree of load in an ATM exchange. The exchange has at least one circuit interface section to which are connected a plurality of physical circuits The exchange terminates the physical circuits and a call control processor which is connected to the circuit interface section or sections and performs call-processing control. A signal control processing unit within the circuit interface section performs call restriction with respect to each individual physical circuit, either in response to an instruction from the call control processor or independently.
