Abstract

PURPOSE:To attain communication between optional terminal equipments automatically by assigning a specific transmission channel and a specific reception channel in advance and allowing a caller station to detect the presence of a carrier of the transmission channel or reception channel assigned to a called station being a communication opposite party. CONSTITUTION:The reception channel and transmission channel of modulator- demodulators M1-M3 are set based on a control data commanded by computers C1-C3. When the modulator-demodulator M2 of the called station T2 detects a carrier of the reception channel chR2, the modulator-demodulator M2 decides whether or not the carrier detection signal is turned on and when the carrier detection signal is not turned on execution of this program is ended, when the signal is decided to be turned on the identification data sent from the caller station T1 to the channel chR2 is received and its identification data is inputted.
