Abstract

PURPOSE:To constitute a transmission system by efficiently combining radio channels for calling with those for control signals as to a cordless key telephone set with a connection between a main unit and each telephone set made via a radio circuit. CONSTITUTION:Telephone circuit control circuit 1, connecting to telephone circuits L1 to Lm serves as the main unit and controls incoming detection, circuit acquisition, and holding; key information from respective telephone sets TEL#1-TEL#n is multiplexed to the main unit via the caLL channel of each telepone set, and information from the main unit to each telephone set is transmitted at a time via the common channel. Circuit information sending circuit 2 of the main unit makes lamp indication when a circuit is acquired and converts circuit information for an individual call to a telephone set, and information control circuit 3 of each telephone set discriminates lamp information (fl) and call information (fb) among pieces of circuit information transmitted and also becomes ready itself to call on receiving its own call information, thereby sending out circuit selection information from the telephone set to the main unit.
