Abstract

A switching apparatus for constructing a system integrating a telephone switching network and a LAN includes: line interface sections, each connected to a transmission line for transmitting a signal on which low-speed data and high-speed data are multiplexed; a low-speed data switch for switching low-speed data demultiplexed in each line interface section; a high-speed data switch for switching high-speed data demultiplexed in each line interface section; and a processor for monitoring and controlling the data traffic passing through the low-speed data switch and high-speed data switch. An address in a designated position in the high-speed data demultiplexed in each line interface section is read out, whereby the association between the low-speed data terminal and high-speed data terminal is identified and stored. By referring to this association, management of LAN terminals can be performed using the maintenance operation procedures used in a conventional electronic switching apparatus.

Claims

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.

2. A switching apparatus according to claim 1, further comprising means, connected to said line interface sections, for determining the association between the low-speed terminal and high-speed terminal by reading the address of the high-speed terminal contained in the high-speed data demultiplexed in each line interface section, and for writing the association into said storage means.

3. A switching apparatus according to claim 2, further comprising means, connected to said monitoring control means, for reading and displaying via said monitoring control means the association between the low-speed terminal and high-speed terminal stored in said storage means.

4. A switching apparatus according to claim 2, wherein in accordance with a blocking instruction input by designating a particular low-speed terminal, said monitoring control means blocks the high-speed terminal associated with the designated low-speed terminal.

5. A switching apparatus according to claim 2, wherein said monitoring control means detects a fault in any one of said high-speed terminals and outputs the detected fault status.

6. A switching apparatus according to claim 5, wherein said monitoring control means outputs the detected fault status to the low-speed terminal associated with said faulty high-speed terminal.

7. A switching apparatus according to claim 2, wherein said monitoring control means monitors the traffic for each high-speed terminal.

8. A switching apparatus according to claim 2, wherein said monitoring control means monitors the high-speed data traffic flowing through said high-speed data switch.
