PURPOSE:To ensure the transmission service in an effective way, by transmitting and receiving the general command information en bloc for each control of a repeating exchange and giving a general command independently within each control. CONSTITUTION:The general command information given from a telephone 1A is fed to a storing device 5A by a push-button signal and via a private exchange 2A and a repeating exchange 4A. Then the device 5A analyzes the received general command information under the control of a control part 5A and then starts the exchange 4A through an originating/incoming part 51 in case the information belonging to a repeating exchange 4B is detected. Thus the information is connected to a storing device 5B via the exchange 4B. While the device 5B detects the received signal through the part 51 and sends the answer signal back to the device 5A. The device 5A feeds the general command information to the device 5B. The devices 5A and 5B transmit an aural message of the general command to the telephones within own service area. |
