摘要： PURPOSE:To detect the existence of irregurality and to execute processing such as the stop of calling when the irregurality is detected, by supervising a subscriber's line which is not permitted as a free line and detecting the existence of a response signal at the terminating to the subscriber. CONSTITUTION:When a calling signal is terminated to a subscriber's telephone (TEL) through a switch frame SWF, a terminating discrimination relay TER is actuated and a relay R receiving the calling signal from an incoming trunk is connected between lines A and B. When the relay R is actuated after receiving the calling signal from the incoming trunk, a subscriber calling relay G is actuated and a calling signal IR is sent to the subscriber's TEL through a contact (g). When the subscriber's TEL responds to the calling signal, a relay F is actuated by a call stopping signal. The actuation of the relay F restores the relay G and the call stopping signal is sent to the incoming trunk by a DC loop passing through a contact fa, a diode D and a line L.

摘要： PURPOSE:To discriminate a free line by an internal function of an exchange without controlling a terminal (subscriber's telephone set), by providing the free line subscriber's terminal with an out-band signal sending function, and detecting the response of a terminating subscriber by an incoming trunk. CONSTITUTION:When the free line subscriber's terminal of a talkie device TK is terminated from an incoming trunk ICT, both the subscribers are connected through a switch frame SWF by the known means. When detecting that the incoming trunk ICT has discriminated the terminating to the free line subscriber from the subscriber's response status by the known method, a controlling device CONT connects the incoming trunk ICT with an out-band signal receiver REC through an incoming trunk connector IC. When confirming that an out-band signal is not sent from the terminating terminal, the controlling device CONT commonds the sending of the out-band signal to an out-band signal generator OSC. The out-band signal is sent to all the free line subscriber's terminals through jumpers on a distributing frame MDF.
摘要翻译：目的：通过交换机的内部功能来区分空闲线路，无需控制终端（用户电话机），通过向免费线路用户终端提供带外信号发送功能，并通过一个终端用户的响应来检测终端用户的响应进入树干。规定：当对讲机设备TK的免费线路用户终端从传入中继线ICT终止时，两个用户通过已知方式通过交换机框SWF连接。当检测到进入的中继线ICT已经通过已知方法鉴别到自由线路用户与用户的响应状态的终止时，控制设备CONT通过进入的中继连接器IC将输入的干线ICT与带外信号接收机REC连接起来。当确认没有从终端发送出带信号时，控制装置CONT将带外信号的发送与外频信号发生器OSC进行通信。带外信号通过配线架MDF上的跳线发送到所有的自由线用户终端。

摘要： PURPOSE:To perform a talkie service utilizing a telephone line without injuring the convenience of a telephone, by supervising continuously a line by permitting a micro current by which no vacant call detection is affected in the line, to flow, on the line in the talkie service. CONSTITUTION:When control parts 7 and 14 detects the vacant state of the telephone line with the outputs of potential monitoring parts 5 and 10, a talkie sending part 6 on a talkie service station device 3 is connected to a talkie amplifier 12 in a talkie service customer station equipment 8. When an incoming from a telephone exchange 1 arrives in a talkie service serving state, the relay and the earth of a subscriber's circuit 2 are separated from the line as known well, and potentials go to the potential polarities of a line A (ground) and a line B (-48V) by input trunks not sown in figure. Changes in the potentials are monitored at the potential monitoring parts 5 and 10 respectively in the station device 3 and the customer station equipment 8, and the control parts 7 and 14 restore relays S in line switching parts 4 and 9, thereby the talkie service is interrupted.

摘要： PURPOSE:To detect a caller number by an incoming side without being affected by a caller before the response of a called party by equipping an ID receiver and a PB oscillator to an outgoing terminal or a outgoing station and an ID oscillator to an incoming terminal or an incoming station and controlling these devices. CONSTITUTION:When a TELA makes a call, an ORG detects the call and closes an ORC connector. On the other hand, when an incoming call comes to a TELB, a TRG detects the incoming call, closes a TRC connector and activates a TS relay. A 3S contact of a TRE of the incoming station is a contact of a 3S relay operated for 1sec and restored for 2sec, a ring tone RBT and a caller retrieval signal ID are transmitted to the caller during the operation of the contact and a ring signal IR is transmitted to a called party. A PB signal transmitted from the outgoing station is received by a PBREC during the restoring time of the 3S contact and stored. The operations above are all finished by the response of the called prty TELB, an OS relay of the outgoing station ORG and a TS relay of the incoming station TRE are restored for attaining normal call.

摘要： PURPOSE:To enable to apply a call processing program developed for a spatial split type exchanger to a time division type exchanger without any change, by providing a function which exchanges a control signal as well as an audio signal for a time division switch. CONSTITUTION:Voices from subscribers A and B are coded at subscriber circuits SUB1 and SUBn and connected to trunks TRK1 and TRKn via a serial parallel converting circuit 8P, a time division network TDNW, and a parallel serial conversion circuit PS. On the other hand, the state of calling of a subscriber, dial and during call, are processed in parallel at the same time slot as an audio signal bit via a multiplex circuit M. Thus, a trunk scanning circuit TSCN receives control information representing the state of subscribers in the same way that the information is received from a trunk connecting the subscriber. Further, a signal such as polarity inversion can be transmitted reversingly via a separating circuit D with the similar method from a relay controller RC.

摘要： PURPOSE:To facilitate the transmission of announcement in an abnormal congestion mode without increasing the software load, by connecting previously the output side terminal of a time division switch to a sound source terminal corresponding to a subscriber class when a call bus is disconnected. CONSTITUTION:In case an abnormal congestion occurs in such a degree that it is on a level just to limit the outgoing of the general subscribers, a changeover switch 46 is changed with an announcement device 46 connected to a sound source terminal 37 to transmit the announcement informing the outgoing limitation to a general subscriber circuit, e.g., a subscriber circuit 30 which is connected to the terminal 37. After this, an information on the outgoing limitation can be heard from the device 46 with no intervention of a software when a telephone 28 is picked up. In case the congestion increases to cause the need for the outgoing limitation of an important subscriber, a changeover switch 45 is switched to allow even the important subscriber to hear the announcement of the outgoing limitation through an announcement device 44. In these cases, a subscriber who is talking at a moment when outgoing limitation starts can complete the talking without receiving any effect.

摘要： PURPOSE:To transmit the communication line polarity reversing pulse excellent in the noise interupting characteristics, by providing the DC communication current control means and performing the polarity inversion of communication line while no DC communication current flows. CONSTITUTION:When the start pulse ST indicating the transmission of charging pulse is incoming, a counter CNT is reset, a flip flop FF is set, and clock pulse is counted when the counter CNT is in the state of operation. The output of the count CNT is input to address terminals A0-A13 of ROM for address designation. Further, the output X1 controls the operation of a communication line polarity relay P, and inversion and restoration of communication line are made with the contactes P1, P2 of the communication line polarity relay P. Since the inversion and restoration of this polarity is made at the section when the current value is zero, noise can not almost be produced.

摘要： PURPOSE:To limit the unavailable range of the matrix caused by the ON fault of the diode down to 1/mXn by giving the complex connection the dividing diodes in the same X and Y directions of m X n units of division matrixes. CONSTITUTION:Group dividing diodes DX11-DXrn plus DY11-DYsm are provided. In case the ON fault occurs to diodes D (1, 1) within division matrix MTX11, the selective operation is given to driving circuits Xp and Ys. As a result, only relays L (p, s) within MTX1n have operation via the loop formed through DXpn and DXsi. In this case, it is impossible to give the normal driving to relay L within the same MTX11. But the unavailable area is reduced down to 1/mXn in the whole matrix in case the ON fault occurs at D (1, 1). As a result, the entire matrix never becomes faulty to limit sufficiently the effect of the fault.
