<p>PURPOSE:To attain complete full duplex communication in multichannel by attaining the transfer of a 1st incoming signal duplicatedly with the 1st outgoing signal so as to shorten a time up to a fixed communication path. CONSTITUTION:A sequence control section 90 controls a switching gate section 40 in response to the discrimination by a first arrival input detection section 60a of a start control section 60 and connects the discriminated input port to all output ports except those corresponding to the discriminated input ports and transfers a signal to them. Then an input detection section 60b of the start control section 60 discriminates input ports not receiving the signal within a prescribed period from the discrimination of the detection section 60a among the input ports corresponding to the output ports receiving signal transfer among the input ports. When any input port receiving the signal after the lapse of the period exists, the control section 90 controls the gate section 40 to connect the input port to the output ports corresponding to the input ports having the signal at first and to connect the input port having first signal to the output ports corresponding to the input port receiving the signal after the lapse of the period and to disconnect the other input ports to the output ports.</p> |
