    • A method of transmitting signalling along a bidirectional digital transmission link consists in transmitting from an intermediate equipment of the link a signalling message in two parts. One is a characterizing part the form of which depends on the signalling type and which is substituted for data of one of the digital bit streams carried by the link in the direction from one of the terminals referred to as the processing terminal. The other is a localizing part whose form is independent of the signalling type and which is substituted for data of the digital bit stream carried by the link in the direction towards the other, so-called relay terminal. The relay terminal responds by sending an acknowledgement message to the processing terminal, the time-delay of this relative to the characterizing part being used to identify the sending equipment. A signalling message transmission circuit controls switching circuits inserted into the paths of the digital bit streams carried by the link. The equipment for transmitting signalling along a bidirectional digital transmission link comprises a clock circuit defining in terms of the period of its output signal the duration of a signalling message characterizing part. Its half-period defines the duration of a localizing part. There is also a circuit for selecting the first complete period of the clock circuit output signal after a signalling transmission request, as well as circuits for composing the two parts of the message.
    • 沿着双向数字传输链路发送信令的方法在于从链路的中间设备发送信令消息两部分。 一个是表征部分,其形式取决于信令类型,并且代替链路在从被称为处理终端的终端之一的方向上携带的一个数字比特流的数据。 另一个是定位部分,其形式独立于信令类型,并且代替链路在朝向另一个的方向上携带的数字比特流的数据,即所谓的中继终端。 中继终端通过向处理终端发送确认消息来进行响应,其相对于表征部分的时间延迟用于识别发送设备。 信令消息传输电路控制插入到由链路承载的数字比特流的路径中的切换电路。 用于沿着双向数字传输链路发送信令的设备包括时钟电路,其根据其输出信号的周期定义信令消息特征部分的持续时间。 其半周期定义了本地化部件的持续时间。 还有一个电路用于选择信令传输请求后的时钟电路输出信号的第一个完整周期,以及用于组成消息的两个部分的电路。

    • Method and apparatus for looping around a digital transmission line (150) at a predetermined channel unit (172) to test the line from either end of the line. Each channel unit in the line is responsive to a first and a second received control code to perform one of two operations. When the first and second received control codes are both first predetermined control codes from one end of the line, the data channel assumes a state to pass the second received first control code and any subsequently received control codes to the next channel unit. However, when the first and second received control codes are first and second predetermined control codes from the one end of the line, respectively, the data channel unit connects the transmit path from the one line end to the receive path back to the one line end, thus looping back to the digital transmission line. To loop around a line at a predetermined channel unit, a maintenance circuit (152) at one line end applies an individual first predetermined control code for the predetermined channel unit and each of the intermediate channel units followed by the application of a second predetermined control code for the predetermined channel unit. The first channel unit from the end of the line passes the second received first control code and any subsequently received control codes to the next channel. This continues for each unit until the predetermined channel unit receives only a first and a second predetermined control code. The second received second control code causes the unit to loop around the transmission line. A maintenance circuit at the other end of the line can likewise loop around the line at any channel unit. A third predetermined control code causes each of the receiving channel units to return to their previous data transmission state.

    • An orderwire communication scheme for a fiber optic communication network includes terminal station equipment associated with the central offices at opposite ends of the network and signal regenerator equipment at the repeater sites disposed between the terminal stations. The communication format along the link is a data-over-voice scheme, the data being digitally encoded on an FSK modulated carrier. In carrying out supervisory functions with respect to each of the stations along the link, command messages are conveyed from the terminal stations at one of the central offices to respective stations along the link in the form of command instructions. Each command message from a central office's terminal station contains the address of the recipient station for whom the message is intended followed by a specific encoded instruction. The instruction may contain a request for information from the addressed site as to equipment conditions at the side and/or a directive that the equipment at the site perform a particular task. In reply to the command message sent to it, the addressed site transmits a response message back to the source station, representative of the status of a particular equipment condition or operation as requested by the command instruction. In this manner, supervisory personnel at each central office may remotely monitor and control the operation of the commuication equipment at the various sites along the link and thereby take correction maintenance or protection channel substitution action where and when required. The digital message transmission scheme also provides facility for fault/alarm reporting, testing the bit error rate of individual channels of the repeater and the transceiver equipment at each terminal station when requested, and is used for paging signalling between central offices.

    • The remote monitoring system locates individually the pairs of intermediate amplification circuits in a remote location in the transmission line between a monitoring station and a monitored station in which circuit a fault diminishing amplification is to be located. The monitoring station transmits remote location signals and other control signals which can be mixed with the data signals normally transmitted over the line. The monitoring station analyzes any faults in the signals transmitted and looped in the line and also carries out remote-control of the gain variation of each amplification circuit without normal transmission of the data signals being interrupted. Signals transmitted from by the monitoring station over the forward channel of the line control four loops of the inputs and outputs of a remote located pair of amplification circuits and a gain regulating means inserted in the negative feedback loop, or inserted upstream or downstream of each amplification circuit in order to change its gain. The transmission line is of the analog, digital or digital-analog type and is supported by means of a cable, optical fibres, radio links or the like.

    • The present invention discloses a method for carrying out a loopback test in a data communication system having a first data communication station, a second data communication station and a transmission line connected therebetween. The first data communication station transmits a succession of a first pseudo-random noise signal, a loopback test signal and a second pseudo-random noise signal to the second data communication station by utilizing a usual information data channel, and requires no special channel for carrying out the loopback test. When the second data communication station detects the first pseudo-random noise signal, it transmits the loopback test signal to the first data communication station in order to check the coincidence of the transmitted and the received loopback test signals. The second pseudo-random noise signal denotes the end of the loopback test.

    • A system is described for randomly addressing any one of a plurality of remotely located stations connected by means of an electromagnetic wavepath. At the addressing point an addressing signal, comprising a series of m signal bursts, is generated and coupled onto the wavepath (11), where m is an integer and corresponds to the number of stations the addressed station is away from the addressing point. Each remote station includes means (33, 34, 41, 43) for deleting one signal burst and retransmitting the remaining signal bursts. Each station also includes means (34, 38, 42, 43, 44, 50, 51) for recognizing when only a single signal burst is received and for responding in a prescribed manner. By means of such a "count-down" technique, the m.sup.th station from the addressing station is accessed. it is an advantage of such a system that the addressing circuit is the same at all the remote stations.
