<p>PURPOSE: A complex line type communication relay system is provided to rapidly and accurately diagnose malfunctions of components. CONSTITUTION: Distribution units(140,150) amplify and output inputted signals. Each distribution unit combines a signal of a reception line and a transmission line through a transmission and reception line. Each distribution unit separates the transmission line from the reception line and transmits the signal of the transmission and reception line. Each unit(142,143,152) is connected to one of the distribution units through the transmission and reception line. Each separation unit amplifies the signal. Each separation unit distributes the amplified signal to a transmission antenna and a reception antenna. [Reference numerals] (110) External antenna unit; (120) Control unit; (130) Amplification unit; (140,150) Distribution unit; (142,143,152) Separation unit; (144,145,154) Internal antenna unit</p> |
