摘要： PURPOSE:To enhance both the reliability and the economical perofmance by replacing the contact of the multi-contact relay with two units of the diode and then to constitute the matrix which drives the magnetic ratch relay via the diode. CONSTITUTION:The circuit contains transistors TrYSO-YSj for functioning of the magnetic ratch relay, TrYRO-YRj for release and control of the magnetic ratch relay, diodes DSOO-DSoj, DSio-DSij, DRoo-DRoj and DRio-DRij respectively. For the operation of magnetic ratch relay Rij, Tr.TXi if first driven by line information ''i'' to actuate relay Xi, and then Tr.YSj is driven by row information ''j'' and others to actuate Rij. After this, the driving is stopped for Tr.TRo and TXi plus YSj for release of Tr.Rij. Thus, Xi is released but Rij continues operation. Then for release of Rij, Tr.YRj is driven by row information ''j'' and others. Thus, the current of the opposite direction to the operation time flows to Rij to release Rij.

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 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 equalize output phases of PLL circuits by confounding systems between phase integrators to select the output of one integrator as the output phase of both systems by an operation system designating control signal and giving the integrator output of one corresponding system as the feedback phase to a PLL where the feedback loop is opened and setting the input phase to the output phase of the integrator of the other system. CONSTITUTION:Systems are confounded between outputs of two voltage controlled oscillators 41 and 42 to select the output of one of voltage controlled oscillators 41 and 42 as the output signal of both systems by the operation system designation control signal, and the output of the voltage controlled oscillator of one corresponding system is supplied as the feedback signal to the PLL system where the feedback loop is opened by the operation system designation control signal. The input signal is switched to the output of the voltage controlled oscillator of the other system of system confounding. Thus, equal output phases are always obtained, and phase jump of an output clock does not occur even at the time of dual PLL operation system switching.

摘要： PURPOSE:To discontinue a service once with the judgment of a subscriber during the service and to attain the calling with an incoming request subscriber by informing a picture center of an incoming request and sending an incoming request image from the picture center to the subscriber during the picture service. CONSTITUTION:While a picture service subscriber A receives the picture information of a captain service which is one type of a picture service, the subscriber A executes the incoming from a subscriber B via an incoming trunk 7, and then, a captain center sends the picture information to show the incoming request is executed, via an outcoming trunk 8 for the capstan to the subscriber A during the picture service. When the subscriber A confirms the incoming request picture with an image terminal 4, the captain service is temporarily discontinued by the self-will, the responce is executed to the subscriber B and the calling can be executed.

摘要： PURPOSE:To easily exchange a magnetic recording mechanism by providing a mechanism foir attaching and detaching electrically an electronic circuit package in a storing case and loading and unloading this package to and out of the case. CONSTITUTION:Electronic circuit packages (E packages) 2a-2n is set on a shelf 1 together with an electronic circuit package (F package) 3 that contains a FDD 11 which drives a floppy disk. Then the 1st and 2nd contact plug parts 7 and 14 secure connection to a mutual connection line 17 consisting of a power supply wiring 17a and a logic wiring 17b. Thus an electronic circuit 8 is connected to the FDD 11 to record prescribed information. If the exchange of the package 3 is desired, another package F is used instead of the first one. This attains an extremely easy exchange of a magnetic recording mechanism.

摘要： PURPOSE:To add an ID function easily, by providing an originator's number (ID signalling device) sending device for each individual subscriber handled by a crossbar switchboard, etc. CONSTITUTION:A subscriber SUB is connected to a next device (service center, etc.) through a call switch SWF and an outgoing trunk OGT. An ID request signal from the following device is received by the outgoing trunk OGT and relayed to a subscriber device SUBE through a channel. The subscriber device SUBE controls the ID sending device IDSND used in common for economization to send an ID to the next device. The ID request signal from the following device is in DC format (polarity inversion, etc.) and received by the outgoing trunk OGT easily. Said ID request signal employs a different signal form from signals used by lines A, B, and C conventionally such as answer, charging, on- hook signals. The 1st answer signal (polarity is inversed) and the 1st metering pulse (C-line course) of the crossbar switchboard are inputted to the subscriber device at the same time without fail, so a signal form which gives a time difference between both signals in transmission or does not send either signal is used for the ID request signal.
摘要翻译：目的：通过为由交叉开关板等处理的每个用户提供发送者号码（ID信号设备）发送设备，轻松添加ID功能。构成：用户SUB连接到下一个设备（服务中心等））通过呼叫开关SWF和输出中继线OGT。来自后续设备的ID请求信号由输出中继线OGT接收，并通过信道中继到用户设备SUBE。订户设备SUBE控制用于节省的共同使用的ID发送设备IDSND，以向下一个设备发送ID。来自以下设备的ID请求信号是DC格式（极性反转等），并且由出站中继线OGT容易地接收。所述ID请求信号采用与线路A，B和C所使用的信号不同的信号形式，通常是诸如应答，充电，挂机信号。交叉开关柜的第一应答信号（极性反相）和第一测量脉冲（C线路线）同时输入到用户设备，因此信号形式给出两个信号之间的时间差传输或不发送任何信号用于ID请求信号。
