用の制御ポイントが必要であつた。 Generally, telephone exchanges have a line monitoring function in trunk trunks for detecting line breaks.
As for the configuration that performs this line monitoring function, the line monitoring circuit that monitors the battery of the game trunk on one line detects a line disconnection due to the disconnection of the monitoring current due to one line break in the relay line, and then from the detected trunk side to the game trunk line. When notifying the trunk's track monitoring circuit of a line break condition by cutting off the monitoring current by disconnecting the battery in the detecting trunk, conventionally a dedicated disconnection relay was required to cut off the monitoring current to the opposing team. . This required a disconnect relay and a dedicated control point for the disconnect relay.

ある。 In order to achieve the above object, the present invention passes the battery of the opposing station through one line of a relay line, and sends a monitoring current through the high resistance ground of the own station, and when the line monitoring circuit that monitors line breakage detects a line breakage, It is necessary to send a disconnection signal to the opponent. At this time, in order to break the loop of monitoring current to the opposing team, use the C position relay that is in the monitoring loop and operates when dial pulses are sent out, and when switching to the dial pulse sending circuit, the A position relay for dial pulse sending is activated. Since it is open, the monitoring loop is disconnected by the operation of the C position relay.

In the figure, LSV0 and LSV1 indicate line monitoring circuits, and LDT0 and LDT1 are trunk line trunks that are opposed via a trunk line. The line monitoring circuit LSV0 of the trunk line trunk LDT0 passes through one line B 0 - A 1 of the trunk line, and is connected to the C position C1 1 of the trunk line trunk LDT1 of the opponent station → the chain coil L 2 → the contact og1 1
Configure a DC circuit with the path. When the relay line B 0 - A 1 is normal, the monitoring current by the battery of LDT1 is
LSV0 detects and determines that the line is normal.

路断を通知されることになる。 At this time, if the trunk line B 0 -A 1 becomes disconnected, the line monitoring circuit LSV0 of LDT0 detects the line disconnection. Trunk of relay line for game when line break occurs
In order to notify LDT1, LDT0 is a track monitoring circuit.
Operate C position relay C0 under the control of LSV0. (Not shown) Contact C01 closes due to C0 operation, so B1 of the DC circuit configured by LSV1
→A 0 →C0 1 →L 0 →og0 1 route is disconnected. Therefore, the line monitoring circuit LSV1 detects line breakage because the monitoring current no longer flows. in this way,
Trunk on the side where line breakage of trunk line B 0 → A 1 was detected
When LDT0 operates C position relay C0 and switches to the dial pulse sending circuit, dial pulse sending contact a 0 is open, so contact C closes and line monitoring circuit LSV1
The DC circuit of B 1 -A 0 →C0 1 →L 0 →og0 1 that was configured is disconnected, and LSV1 is notified of the line disconnection by LDT0.
