PROBLEM TO BE SOLVED: To provide an inter-system connection method capable of preventing (avoiding) a collision (interference) of a control channel between base stations by sharing a radio control channel synchronizing signal between systems without connecting the systems by a dedicated capable. SOLUTION: A first system and a second system are connected through a phantom feedable LAN cable. A synchronizing signal generator connected to a center tap of a secondary winding of a first transmitting transformer and a center tap of a primary winding of a first receiving transformer generates a radio control channel synchronizing signal. A synchronizing signal receiver is connected to a center tap of a primary winding of a second receiving transformer and a center tap of a secondary winding of a second transmitting transformer receives the radio control channel synchronizing signal.
