上につながる。 During communication between the non-telephone terminals 4 of the composite subscriber terminals 1 and 2, the communication abnormality detection circuit 9 in the non-telephone terminal 4 of the composite terminal 1 detects a hardware failure in the own terminal, or detects a hardware failure in the receiving circuit. When receiving notification from 8 that a command or data that does not conform to the transmission procedure has been received, the communication abnormality detection circuit 9 notifies the control unit 6 of the communication abnormality via the data bus 15. When the control unit 6 determines that there is an abnormality during communication,
Telephone switching command sending control circuit 13 in the control unit 6
controls the transmitting circuit 7 to send a telephone switching command to the non-telephone terminal 4 of the multifunction terminal 2. The command signal is sent to the telephone line 20 through the path of transmitting circuit 7 - hybrid transformer 17 - CML relay contact cml 0 16. The non-telephone type terminal 4 of the compound terminal 2 receives the command signal through the path of the CML relay contact cml 0 16 - the hybrid transformer 17 - the receiving circuit 8. The command received by the receiving circuit 8 is transmitted to the control unit 6 via the data bus 15. When the control unit 6 determines that the telephone is switched due to an abnormality during communication, a CML (not shown) is sent from the telephone switching control circuit 14 in the control unit 6 to the network control unit 5.
Drive the relay. Then, the cml 0 contact 16 operates and switches the telephone line 20 from the non-telephone terminal 4 to the telephone 3 side. Further, the subscriber calling buzzer 10 is driven from the buzzer/lamp control circuit 12,
Lamp 1 for calling the subscriber and displaying telephone switching
1 is lit to notify that the call has been switched due to an abnormality during communication. On the other hand, after sending the telephone switching command, the non-telephone terminal 4 on the multifunction terminal 1 side
The telephone line 20 is switched from the non-telephone terminal 4 to the telephone 3 in the same way as the operation after receiving the telephone switching command at the non-telephone terminal 4 of the multifunction terminal 2 . Further, the subscriber calling buzzer 10 is driven to call the subscriber, and the telephone switching display lamp 11 is turned on to notify that the telephone has been switched due to an abnormality during communication. This notification allows the subscribers of compound terminals 1 and 2 to answer the phone and inform them that the information transmission has been interrupted due to a communication abnormality and that the information will be retransmitted immediately, or
In the event of a terminal failure, information can be retransmitted without having to restore the terminal, as information can be communicated such as what time and minute the information will be retransmitted. Alternatively, it is possible to grasp the status of a terminal failure and schedule a retransmission time, leading to improvements in economic efficiency, operability, and communication reliability.
