    • There is disclosed a data transmitting and receiving circuit extremely advantageous when applied to a key telephone system. The data transmitting circuit comprises a voltage dividing circuit for dividing a power supply voltage to apply the divided voltage to one end of a primary winding of a transformer, and a driver circuit comprising a pair of transistors connected in series between the power supply and a common potential terminal, the node of the transistors being connected to the other end of the primary winding of the transformer. When data signal is transmitted, the data transmitting circuit is operative to complementarily turn and off the pair of transistors in accordance with the data signal. In contrast, when data is not transmitted, the data transmitting circuit is operative to cut off both the transistors. Thus, the data transmitting circuit can eliminate the possibility that a DC voltage on which a data signal to be transmitted is superimposed undesirably changes. Further, the data receiving circuit comprises a voltage divider common to the above-mentioned voltage dividing circuit, a comparator having a comparison input connected to the other end of the secondary winding of the transformer, and a reference voltage supply circuit for selecting either of two reference voltages depending upon a binary output level of the comparator to deliver the selected one to the reference input of the comparator. Thus, the data receiving circuit can provide a stable and steady receiving condition when a data signal superimposed on a DC voltage is received to change the data signal into a binary received signal.
    • 公开了一种在应用于密钥电话系统时非常有利的数据发送和接收电路。 数据发送电路包括：分压电路，用于分压电源电压以将分压电压施加到变压器的初级绕组的一端;以及驱动器电路，包括串联连接在电源和公共端之间的一对晶体管 电位端子，晶体管的节点连接到变压器初级绕组的另一端。 当发送数据信号时，数据发送电路可根据该数据信号互补地对和关掉一对晶体管。 相反，当不发送数据时，数据发送电路可操作地切断两个晶体管。 因此，数据发送电路可以消除其上叠加有数据信号的直流电压被不期望地改变的可能性。 此外，数据接收电路包括与上述分压电路相同的分压器，具有与变压器的次级绕组的另一端连接的比较输入的比较器和用于选择两个 参考电压取决于比较器的二进制输出电平，以将所选择的电平输出到比较器的参考输入端。 因此，当接收叠加在DC电压上的数据信号以将数据信号改变为二进制接收信号时，数据接收电路可以提供稳定和稳定的接收条件。

    • An electronic key telephone system which features a bi-directional serial data stream for transmission of control signalling between common control and station circuitry over a single power/data conductor pair independent of the speech conductor pair. The common control central processor includes clock and timing logic circuitry for defining a serial multiphase bit stream of clock and data pulses, each clock pulse initiating a new bit position. Frame intervals are defined by one or more bit positions devoid of both a clock pulse and data information. Common and proprietary data information in the form of unipolar binary signals is multiplexed onto the serial bit stream either at the central processor, at a station circuit, or at the station, and interlaced with clock pulses at predetermined word and bit positions within each frame for communication among the various system circuit elements. Use of the serial data stream transmission scheme simplifies the station electronics such that conventional single line telephone instruments may be configured for use in an electronic key telephone system.

    • A telephone station set (S1) is arranged to communicate voice signals over a voice communication pair (V1) and to communicate ringing, switchhook supervision and visual signaling over a separate signaling pair (C1). An amplitude and polarity modulated alternating voltage on the signaling pair (C1) provides current flow in one direction for visual signaling while distinguishable amounts of current flow in the opposite direction to provide switchhook and ringing supervision. The switchhook supervision current and the ringing signal current both flow through a series connection of a buzzer (B1) and a break switchhook contact (SH2) in the telephone station set. An off-hook condition at the telephone interrupts current flow on the signaling pair (C1) providing a switchhook supervision signal while simultaneously terminating the ringing signal.
    • 电话机组（S1）被布置为通过语音通信对（V1）传送语音信号，并且通过单独的信令对（C1）来通信振铃，切换监听和视觉信令。 信号对（C1）上的幅度和极性调制交流电压在一个方向上提供电流，用于视觉信号，同时可分辨量的电流在相反方向流动，以提供开关和振铃监控。 开关监控电流和振铃信号电流都流经电话机组中蜂鸣器（B1）和断路开关触点（SH2）的串联连接。 电话中的摘机状态中断信号对（C1）上的电流，提供开关监视信号，同时终止振铃信号。

    • The disclosure relates to a four conductor circuit arrangement providing two communication channels between a control unit and a terminal device. Power feed and bi-directional signalling are accomplished simultaneously over the same four conductors used for the two commmunication channels without interference. The signalling from the control unit to the terminal is accomplished by means of a voltage modulator circuit in the control unit by which voltage pulses are transmitted via a phantom circuit arrangement over the four conductors to the terminal unit. The voltage pulses are sensed from the phantom circuit in a data receiver which is located at the terminal unit. Connected to the phantom circuit in the terminal unit is a voltage regulator circuit which receives power from the control unit via the four conductor phantom circuit interconnecting the control unit and the terminal. In series with the voltage regulator circuit is a constant current sink and an inductor. A current modulator circuit is provided in parallel for impressing current data pulses generated in the terminal onto the phantom circuit, which are, in turn, received by a receiver circuit in the control unit.A preferred data format is disclosed as a method for transmitting information between the control unit and the terminal.The preferred embodiment for the disclosed four conductor communication circuit and the disclosed data format is in a key telephone system in which the control unit is a station card in a key service unit and the terminal is a key telephone station set.

    • A digital concentrator system for use with a plurality of digital transmission systems is disclosed. The concentrator is employed at a central office terminal (100), and at a remote terminal (102), with an interconnecting digital transmission path (108). In the transmit direction at each terminal (110, 112), a plurality of multiplexed encoded signal streams are demultiplexed and the encoded signals stored. A selected number of encoded signals are retrieved and multiplexed for transmission to a distant terminal (112, 110) as a concentrated pulse stream (123,175). In the receive direction at each terminal (110, 112), the encoded signals in the multiplexed concentrated stream (125, 177) are demultiplexed and stored. The stored encoded signals are retrieved and the original number of encoded signal streams derived for transmission to the transmission terminal (100, 102). Supervisory and control communication between the two concentrator terminals (110, 112) is achieved by way of data messages on a derived data link. Operation between the transmit and receive directions at each terminal is asynchronous and controlled by a microcomputer (124, 160).
