Abstract

PURPOSE:To eliminate the movement of a terminal and adjustment at a newly subscribing time by adjusting a branch monitoring output with the directional coupler of a receiving signal to a data terminal and further subscribing a television receiver through a band-pass filter to a network. CONSTITUTION:When the adjustment of a receiving signal level in respective data terminals 32a, 32b,... is executed, a reference signal is generated in a reference signal generator 35 and sent through a head end 34 to a transmission path 31. The receiving signal inputted to a signal level adjustor 11a is supplied to a distributor 16 and a signal in a data signal side is divided from a transmission signal through a divider 17 and further, it is distributed to a data terminal 13 and a monitoring terminal 14 through a demultiplexer 18 and a directional coupler 21. Here, a level which the terminal 32a needs is adjusted by a variable attenuator 19. A transmission signal level is adjusted by a variable attenuator 20. Further, a signal distributed to a TV signal side by the distributor 16 is supplied through a BPF22 to a television receiver terminal 15. Thus, the movement of the terminal and the adjustment at the newly subscribing time can be eliminated.
