Then, prior to the using start of this system, the ID chip 3 is inserted to an ID chip interface part 5, a master station control part 6 reads the ID code stored in the ID chip 3 and transmits the ID code to the slave station telephony equipment 2 and the ID codes are confirmed between a master station telephony equipment 1 and the slave station telephony equipment 2. Thus, just by inserting the ID chip 3 to the ID interface part 5, the ID codes between communication terminals are mutually confirmed.
