ABSTRACT:
In the frequency-division multiplex broadband multimedia network of this invention, a plurality of transmission paths are laid out in a matrix, with transmission path switches being arranged at respective lattice points. Each transmission path switch monitors a transmission path current. When a transmission path switch detects that a current has been cut off, a portion where a communication trouble is caused is disconnected from the network, and the switch connects a portion at the downstream side of this tansmission path switch to another adjacent transmission path.
