PURPOSE:To make the dialing and call reception possible when any connector stays within a range into which a radio wave reaches a slave set. CONSTITUTION:A same BID is set to each of connectors 21-2n and dialing by using the common BID to each connector is set to each of slave sets 31-3m. Each of the connectors 21-2n scans radio channels in an optional timing and a connector 22 whose timing is coincident with a channel by dialing of the slave set 32 replies the call from the slave set 32. |
