Abstract

PURPOSE:To prevent contention of a call from a cordless telephone set and an incoming call to a connection device by sending a call signal when an incoming signal whose identification code is coincident even in the presence of a carrier and sending a call reply signal by the connection device when the connection device detects the call signal during the transmission of an incoming call signal. CONSTITUTION:When a cordless telephone set 10 detects hook-off during standby, the cordless telephone set 10 detects a carrier, the transmission is set in the absence of the carrier and the transmission is set when an incoming signal whose identification code is coincident even in the presence of the carrier and a call signal is sent to a connection device 20. Upon the receipt of a call signal whose identification code is coincident during the transmission of the incoming call signal, the connection device 20 interrupts the transmission of the incoming call signal and sends a call reply signal to the cordless telephone set 10 to apply call connection. Thus, the contention of the call of the cordless telephone set 10 and the incoming call to the connection device 20 is prevented.
