摘要： PURPOSE:To attain the communication without lowing a voice level, by bringing a channel current supply section to high impedance, and terminating in matching at a 2/4-wire converting section. CONSTITUTION:When a specific number from a telephone set 1 is detected 12- 17, a control circuit controls switches 6-9 to transmit a ringing signal of interphone 26 and to attain mutual calling between A and B telephone sets 1, 2. Further, switches 20, 21 for connection and disconnection of a 2/4-wire converting circuit 18 are controlled for opening to bring an impedance in terms of a voice frequency viewed from the telephone sets 1, 2 to a subscriber circuit 25 into a high level state. As a result, a call current is applied to the telephone sets 1, 2 from the subscriber circuit 25 and the subscriber circuit 25 to the voice is made to non-connecting state, allowing to prevent the decrease in the voice level.

摘要： PURPOSE:To attain the dial-in to a PBX only with a slight modification of the existing hardware and software by modifying slightly hardware for exclusive use of community, that is, a relay circuit, in a time division exchange. CONSTITUTION:When an exchange receives a PBX selection dial signal and an extension dial signal of the PBX, a loop is first formed in a subscriber circuit 1 in the same way as a conventional one. With this loop formation, a DC current flows in a subscriber line as shown in a figure (a), and the subscriber circuit 1 generates a signal for showing that a response with respect to the activation is returned. A relay node switching means of the exchange for responding said signal switches relay nodes 5 and 6 to the dotted line side as shown in a figure (b). Then the subscriber circuit 1 stops supply of electric power and switches relay nodes 7 and 10 in the attitude decided by the having received extension dial signal. Thus said extension dial signal can be transmitted to the PBX as shown by the dotted line in a figure (c).

摘要： PURPOSE:To transmit the talkie to all subscribers without lowering the traffic capacity for a subscriber line concentrator of a time-division telephone switchboard, by providing a talkie exclusive highway. CONSTITUTION:A time slot having a non-call pattern of a distribution highway 4 is usually connected to a talkie circuit 130 via a line concentration switch 301, and no audio signal is delivered to the output of the circuit 130. When it is required to transmit the talkie to a subscriber 10b of a low call factor in an abnormal congestion mode, a time slot having a digital talkie signal pattern of the highway 4 is connected to the circuit 130 with switching of connection of the switch 301. Then the analog talkie signals are transmitted to all subscribers 10b from the circuit 130. At the same time, the talkie signal is individually transmitted when necessary to a subscriber 10a of high call factor with connection of the switch 301. As a result, a function concentrating part 123 is not needed within a circuit 120 for subscriber 10b. This never lowers the traffic capacity.
摘要翻译：目的：通过提供对讲机专用公路，将对讲机发送给所有用户，而不降低时分电话交换机的用户线集线器的流量。构成：具有分配公路4的非呼叫模式的时隙通常经由线路集中开关301连接到对讲电路130，并且没有音频信号被传送到电路130的输出。当需要在异常拥塞模式下将对讲机发送到低呼叫因子的用户10b，具有公路4的数字对讲机信号模式的时隙通过开关301的连接切换连接到电路130.然后模拟对讲机信号从电路130发送到所有订户10b。同时，当需要时，对讲机信号被单独发送到具有开关301的连接的高呼叫系数的用户10a。结果，功能集中部分123是在用户10b的电路120内不需要。这样就不会降低流量。

摘要： PURPOSE:To save and reduce power consumption of a gate turn-OFF control circuit by detecting the fact that a P-N-P-N type switch which has gate turn- OFF function has completed the gate turn-OFF, and stopping the operation of a gate turn-OFF circuit. CONSTITUTION:A voltage is generated between the gate and the cathode of a P-N-P-N switch 16 when the switch 16 is conducted, a transistor TR14 is driven, and a collector current is flowed. This current drives the base of a TR5, and when a TR6 is turned OFF, TR10 is turned OFF. The base of a TR12 is driven, the collector current of the TR12 drives the base of the TR13, and the switch 16 is opened. When the switch 16 is opened, the TR14 is interrupted, and the TR10 is also interrupted. Accordingly, the OFF drive is stopped. When the OFF drive is not operated, the TR6 is turned ON from a terminal 2. In this manner, the OFF drive current does not flow after the completion of the gate turn OFF, thereby saving the power consumption.
摘要翻译：目的：通过检测具有闸极关断功能的PNPN型开关已完成门关断的事实，并且停止栅极关断的操作来节省和降低门极关断控制电路的功耗电路。构成：当开关16导通时，P-N-P-N开关16的栅极和阴极之间产生电压，驱动晶体管TR14，并且集电极电流流动。该电流驱动TR5的基极，当TR6关闭时，TR10关闭。 TR12的基极被驱动，TR12的集电极电流驱动TR13的基极，开关16断开。当开关16断开时，TR14中断，TR10也中断。因此，OFF驱动停止。当OFF驱动器不工作时，TR6从端子2接通。以这种方式，在门关闭完成之后，OFF驱动电流不流动，从而节省功耗。
