Description of the Related Art Conventionally, in this type of time division multiplex communication system, a time division multiplex device and a partner time division multiplex device are connected one-to-one via a dedicated line. Therefore, if one time division multiplexer is focused on and there are n time division multiplexers connected to this, the noted time division multiplexer is a dedicated line and the other time division multiplexer is used. And 1 to n
Will be connected. The time division multiplexing device communicates data via the dedicated line and also communicates control information. However, when one time division multiplexer is connected to other n time division multiplexers in a one-to-n connection,
It is necessary to secure n communication paths in the dedicated line, and the dedicated line is monopolized by this amount, so the transmission capacity of the dedicated line decreases, and communication of other communication systems using this dedicated line There was a drawback that it hindered us. In such a case, increase the transmission capacity of the leased line,
Due to various circumstances, the transmission capacity may not be increased, and a method of coping with such a case is required.

する。Next, the operation of this embodiment will be described. For example, the control unit 11 of the time division multiplexer 1-1 calls the control unit 11 of the time division multiplexer 1-2 from the ISDN interface 12 via the D channel of the ISDN network 3 to obtain error information and status information. Request for transmission of control information such as. As a result, when the time division multiplexers 1-1 and 1-2 are connected via the D channel of the ISDN network 3, the control unit 11 of the time division multiplexer 1-2 causes error information in the apparatus and The status information is sent from the ISDN interface 12 to the D channel of the ISDN network 3. This allows
The control unit 11 of the time division multiplexer 1-1 receives and collects error information and status information on the D channel via the ISDN interface 12. After that, the control unit 11 of the time division multiplexer 1-1 sends the ISD from the ISDN interface 12 to the control unit 11 of the time division multiplexer 1-3.
A call is made through the D channel of the N network 3 to request error information and status information. As a result, when the time division multiplexers 1-1 and 1-3 are connected via the D channel of the ISDN network 3, the control unit 11 of the time division multiplexer 1-3 causes error information in the equipment and Status information ISDN
It is transmitted from the interface 12 to the D channel of the ISDN network 3. As a result, the control unit 11 of the time division multiplexer 1-1 receives and collects the error information and the status information on the D channel via the ISDN interface 12.
