Japanese Patent JP3697732
Kind Code:

Abstract:
PURPOSE: To connect even a cordless telephone set which has no control channel even when the slave equipment or master equipment is in the area of another cordless telephone set.
CONSTITUTION: To connect the slave equipment 1 to the master equipment 2 through a specking, data of a connection request is sent to the latter by using a speaking channel which is free when viewed from the former. The latter returns data showing whether or not the speaking channel over which the data of the connection request is sent is in use by using the speaking channel paired with the speaking channel over which the data of the connection request is sent. Until the returned data indicates that the channel is free, the former changes speaking channels to repeat the transmission of the data of the connection request. When the returned data indicates that the channel is free, the former and latter are connected through the free speaking channel.
