１５Ｂを出力する。 FIG. 1 is a configuration diagram illustrating an embodiment of the present invention. First, a line reservation request is sent to the reservation registration device 3 of the reservation control station 1. The registration device 3 checks the desired terminal, date and time, and usage status of the line to determine whether or not the reservation can be registered, and if the terminal is vacant, the reservation is registered. The registration device 3 transfers all the registration information for a certain day reserved and registered in this way to the line control device 4 as a line control data signal 11. The line control device 4 centrally manages all of the line control data signals 11 and sends out registration data regarding a plurality of subordinate control stations 2 as the line control signal 12. When the designated time reserved based on the registered data arrives, the line control devices 4 and 5 send connection/disconnection control commands 15A and 15A to the line switching devices 6A and 6B.

Note that in order to check whether or not the devices 6A and 6B have operated correctly in response to the connection/disconnection control command 15 output from each line control device 4 and 5 to the line switching devices 6A and 6B, the switching devices 6A and 6B are Status signal 16 indicating operating status
A and 16B output from the line switching devices 6A and 6B to the line control devices 4 and 5. A status signal 17 is output from the thus connected video/audio terminal devices 7A and 7B to the line control devices 4 and 5 for checking whether or not the power of the video/audio terminals is turned on. This status signal 17 is constantly monitored by the line control devices 4 and 5 after the line is connected, and when it is detected from the status signal 17 that either one of the terminal devices 7A and 7B is turned on or turned off, The detected line control device 4 or 5 is the line control device 4 of the reservation control station 1, which centrally manages line management using the monitoring signal 18.
to notify that the line is no longer available. The control device 4 refers to the reservation schedule based on this signal 18, confirms the completion of line use, and then performs a disconnection process to the switching devices 6A and 6B controlling the corresponding terminal devices 7A and 7B. To do this, the line control device 4 sends a line control signal 12 to the line control device 5.
The line control devices 4 and 5 output disconnection control commands 15A and 15B to the switching devices 6A and 6B to open the lines. 14 indicates a video and audio signal of the terminal.

理される。 FIG. 2 is a block diagram showing the configuration of the line control device 4 (or 5). In the figure, in the line control device 4, the central information processing unit 101 is connected to the bus line 21.
The following series of management is performed via 0. Transmission and reception of the line control data signal 11 to and from the reservation registration device 3 is performed via the reservation control signal transmitting/receiving section 106. Information such as terminal devices and control stations used on the day is stored in storage unit 1.
It is housed in 05. The line control signal related to the dependent control station 2 is transferred from the storage unit 105 to the line control signal transfer unit 107 for each control station.
The connection/disconnection control of the reservation control station 1 is output from the control command output section 103 to the line switching device 6 as a connection/disconnection control command 15 . Whether the switching operation is normal or not is determined by the status signal 1 indicating the operating state of the switching device 6.
6 is input via the status signal receiving section 104 and checked against the contents of the connection/disconnection control command 15. A status signal 17 indicating whether or not the connected terminal device 7A is being used is input to the video/audio terminal device status signal receiving section 102 and constantly monitored. When a power-off of the terminal device 7A is detected, the line control data stored in the storage unit 105 is referred to. When it is confirmed that the connection is based on the line control data, the connection/disconnection control command 1 is sent from the control command output unit 103.
5 is output to the line switching device 6. In addition, if the terminal device facing the disconnected terminal 7A is the terminal device 7B of the subordinate control station 2, the line control signal transfer unit 1
07, the line control signal 12 is sent to the subordinate control station 2.
Output to. On the other hand, if the terminal device 7B of the subordinate control station 2 detects a power cut, the supervisory signal 18
The signal is input to the line control signal transfer unit 107 as a signal and processed in the same manner as the terminal status signal 17 of the reservation control station 1.
