摘要

PURPOSE:To surely transmit a lamp control signal to a slave machine even in the case that the lamp control signal to be transmitted is generated but cannot be transmitted from the exchange side to the slave machine in the lamp recovery system for multizone system cordless telephone where the exchange and the slave machine communicate with each other by radio. CONSTITUTION:An exchange 1 is provided with a storage means 5a of lamp control information which controls the indication state of a control lamp provided in a slave machine 6, a means 2 which sends the lamp control signal to the slave machine 6 in response to generation of this lamp control information, and a means 5b where the flag which is set at the time of a failure of sending from the lamp control signal sending means 2 and indicates incompletion of sending of the lamp control signal is stored. At the time of originating/ terminating control for the slave machine whose flag is set, the lamp control signal sending means 2 is driven to send the lamp control signal to this slave machine 6.
