The circuit of the ignal ingreleys set) is configured to realize the function of separating the signal from the exchange or telephone into a voice signal and signaling and passing it to the carrier device, and also passing the voice signal and signaling from the carrier device to the exchange or telephone. , signaling from the transport device (S
It operated faithfully with respect to changes in fL). However, when the conveyance device becomes abnormal, the signaling is fixed to the ground or open in order to avoid abnormal operation of the signaling. Conventional USSs operate in response to these signals, so they have the disadvantage that if the signaling is fixed to the ground, the exchange will be activated immediately, and if the signaling is fixed to the ground, the line during a call will be disconnected.

7 is connected, terminal 6 goes to relay 16, terminal 7 goes to relay 1
It is connected to the relay 16 through the contact 18 of 5. terminal 8
is connected to the relay 17 through the contact 19 of the relay 15 and to the terminal 9 through the contact 2o of the relay ]7.

９より搬送装置へ地気信号が送出される。First, the connection signal (17Hz) from the exchange to terminals 1 and 2.
is rectified by a rectifier 14 via a capacitor 13 to drive a relay 15. When the relay 15 is driven, the contact 19 is closed and the relay 17 is driven. Therefore, an earth signal is sent from the terminal 9 to the conveyance device through the contact side.
また端子１，２への交換機からの音声信号はコンデンサ
１１．１２を経由して端子３，４から搬送装置へ送られ
る。Also, the audio signals from the exchange to terminals 1 and 2 are sent from terminals 3 and 4 to the transport device via capacitors 11 and 12.

なされる。Conversely, as a connection operation from the conveyance device, first, a ground signal is received at the terminal 6, and the relay 16 is thereby driven. When the contact 21 of the relay 16 closes, a DC (direct current) loop is formed between the exchange and the relay 15, and a connection operation is performed.

質の向上に役立つといった利点がある。In addition, if the transfer device detects a fault, the signal at terminal 6 is set to open and the signal at terminal 7 is fixed to the ground. Since the contact 18 of the relay 15 is closed, the operation of the relay 16 is maintained by the earth signal of the terminal 7. If the relay 16 is not operating, the contact 18 of the relay 15 is open, and the signal of the terminal 6 becomes open. Since it is fixed, relay 16 continues.
is kept inactive. (A (Effects of the Invention) As explained above, this invention is provided with a circuit that controls the relay 16' using the contacts of the relay 15 and the failure notification signal from the conveyance device, so instantaneous interruptions occur due to fading of the wireless line etc. This has the advantage that calls are not disconnected on the line, which helps improve line quality.
