Abstract
PURPOSE: To realize a signal transmission path by a simple installing construction, by connecting a terminal device controller in the halfway position of a branch signal transfer circuit as a slave and transferring signals.
CONSTITUTION: One end of output signal transmission path 6 which transmits output signals from communication controller 2 receiving and transmitting signals from and to a center equipment and a terminal equipment is matched by 8. Branch box 7 which branch and relays, at least, one output signal is provided in the halfway position of transmission path 6, and one end of branch signal transfer path 9 which is branched and relayed by branch box 7 is matched and terminated by 5. Then, terminal device controller 4 is connected to the halfway position of the branch signal transfer path as a slave to make it possible to receive branch signals independently, and signals are transferred. As a result, a signal transmission path can be realized by a simple installing construction.
