摘要： The method consists in momentarily replacing the data in a transmitted digital data stream by a remote signalling message which is built up from consecutive sequences, each of which is obtained by repeating a specific binary pattern chosen from a plurality of possible binary patterns which are generated from the second and fourth sub-harmonics of a clock signal at the bit rate of the digital stream, and from logical combinations thereof. FIG. 2 is a circuit diagram of a transmitter circuit for transmitting a remote signalling message. Said transmitter circuit is located in equipments on a very high data rate digital link, which equipments include a circuit (6') for detecting and handling alarms, and a circuit (3) for recovering the bit rate from the digital stream. Divide-by-two circuits (10, 14) and a logic gate (16) serve to generate three kinds of pattern from the recovered clock rate, namely: 0101, 0011, 1000. A sequencer (21) builds up sequences of patterns within a remote signalling message by means of a multiplexer (20) whose inputs are encoded with the message to be transmitted, a pattern generator selector circuit (11, 15, 16), and switching means (18) for inserting the remote signalling message instead of the digital stream.

摘要： Apparatus for implementing a remote signalling method which consists in momentarily replacing the transmitted digital data stream by a remote signalling message which is built up from not more than n identical and nonconsecutive sequences of N bits, with the first sequence of each message being present on each occasion that a message is sent, and with the remaining n-1 sequences of each message representing, by their presence or absence, the values 0 or 1 of n-1 digits in a binary number encoding remote signalling data. FIG. 2 shows a circuit for transmitting a remote signalling message from an equipment along a very high data rate digital link, which equipment is provided with a circuit (6') for detecting and handling alarms, and a circuit (3) for recovering the bit rate from the digital stream. An OR gate (12) associated with dividers (10, 11) implemented in a high speed ECL technology generates a repetitive 1000 pattern on which a sequence is based, and switching device (13) also implemented in high speed ECL technology serves to insert sequences of said pattern into the digital stream to constitute a remote signalling message. The switching device is controlled by message-building logic circuits made from slower I.sup.2 L or Schottky technology.

摘要： The method consists in momentarily replacing the data transmitted by a digital data link with a digital message comprising two non-consecutive sequences, with the first sequence being a prefix sequence and the other sequence being a suffix sequence. The period of time separating the prefix and suffix sequences is variable and encodes remote signalling data. FIG. 2 shows a message transmitter circuit fitted in digital link equipment for operation at a very high data rate, and provided with a circuit (6') for detecting and handing alarms and with a circuit (3) for recovering the bit rate from the digital stream. A pattern generator (10) serves to generate a 1000 pattern and its 0111 complement from the recovered check rate. An oscillator (20) has a period which defines the time interval separating the prefix sequence and the suffix sequence. This oscillator controls a sequencer (25) which in turn controls a prefix sequence building circuit (30) and a suffix sequence building circuit (40) both of which act via logic gates on a circuit for selecting pattern types and on switching means (19) for inserting the selected sequence into the digital stream instead data.

摘要： 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.

摘要： A method of automatic gain control for use in an optical amplification device comprising a variable optical attenuator and an optical amplifier connected downstream of the optical attenuator includes the steps of measuring the power at the input of the amplification device, determining the number of channels at the input of the amplification device as a function of the measured power knowing the attenuation value of a span upstream of the device, and modifying the gain of the amplifier as a function of the number of channels determined in this way.
