1. A switching apparatus to which a plurality of low-speed terminals and a plurality of high-speed terminals are connected via a plurality of transmission lines each for transmitting a signal in which low-speed data from a low-speed terminal and high-speed data from a high-speed terminal are multiplexed, and which is suitable for constructing a switching network among said low-speed terminals and a local area network among said high-speed terminals, comprising:

  • a plurality of line interface sections, each connected to one of said transmission lines, for demultiplexing the multiplexed signal fed via the transmission line connected thereto into low-speed data and high-speed data, and for multiplexing low-speed data and high-speed data for transmission down the transmission line connected thereto;

    a low-speed data switch, connected to said line interface sections, for performing switching of said low-speed data;

    a high-speed data switch, connected to said line interface sections, for performing switching of said high-speed data;

    storage means for storing the association between the low-speed terminal and high-speed terminal connected to each of said transmission lines; and

    monitoring control means, connected to said low-speed data switch, said high-speed data switch, and said storage means, for monitoring and controlling the traffic of low-speed data among said low-speed terminals, and for monitoring and controlling the traffic of high-speed data among said high-speed terminals in association with the corresponding low-speed terminals on the basis of the association stored in said storage means.
