Abstract:
A subscriber terminating equipment which includes a plurality of subscriber terminating packages connected between a plurality of subscriber terminals side and a network interface apparatus side, said network interface apparatus being connected to a network and capable of transferring a signal to a desired destination for accommodating said subscriber terminals, and a relief package having the same construction as that of said plurality of subscriber terminating packages for accommodating the subscriber terminals accommodated in a fault subscriber terminating package which has failed from among said plurality of subscriber terminating packages, comprising:a multi-connection line disposed in the proximity of said plurality of subscriber terminals and connected to each of said plurality of subscriber terminating packages; and a common section connected to each of said plurality of subscriber terminating packages for outputting switching signals to perform switching of a path between said subscriber terminals and said network interface apparatus; said plurality of subscriber terminating packages including multi-connection switches connected to said subscriber terminals and said multi-connection line for connecting/disconnecting electric signals between said subscriber terminals and said multi-connection line, subscriber connection switches connected to said subscriber terminals for connecting/disconnecting electric signals between said subscriber terminals and said network interface apparatus in response to connection conditions of said multi-connection switches, and relief switches connected to said subscriber connection switches; said relief package including a relief switch connected to said multi-connection line for connecting/disconnecting an electric signal between said multi-connection line and said network interface apparatus, a subscriber connection switch connected to said relief switch, and a multi-connection switch provided on a circuit board or a plurality of circuit boards; said common section selecting a pair of packages including a first subscriber terminating package and a second subscriber terminating package from among said plurality of subscriber terminating packages and allocating, if the first subscriber terminating package fails, the second subscriber terminating package as a bypass subscriber terminating package for performing electric connection between the subscriber terminals and said relief package; said relief package and said subscriber terminating packages having the same circuit pattern for connection of the three kinds of switches.
