Abstract
A method of controlling a frame-relay module includes steps of outputting a control-information frame from a control unit connected to an ATM switch, the control-information frame containing data specifying a frame-relay interface circuit as well as a processing command, assembling the control-information frame into an ATM cell and sending the ATM cell, via the ATM switch, to a frame-relay module in which the specified frame-relay interface circuit is present, restoring the ATM cell to a control-information frame by an ATM interface circuit and a cell assembly/disassembly circuit contained in the frame-relay module, causing the specified frame-relay interface circuit to accept the control-information frame, and executing processing, which conforms to the command contained in the control-information frame, in the frame-relay interface circuit.
