Abstract: Decoder having modular constitution for transmission by coded pulses constituted by several identical individual modules wired up and interconnected so as to perform, in interrelation, various elementary functions of the decoding. Each of the individual modules comprises four operational amplifiers, an output amplifier, a switching device selectively connecting the output of one operational amplifier to the input of the output amplifier, and a logic control circuit responsive to coded bits to actuate the switching device.

Abstract: This method including a measurement, by the central station (OLT), of the time interval separating a reference instant of transmission of information signals by the said central station, from the reception, by this central station, of a so-called positioning signal (SW) emitted by a remote station (ONT), a delay time after a reference instant of reception of the said information signals by this remote station, so that the said positioning signal is received, by the central station, within a time period, termed the positioning window, which is not allocated to the reception, by this central station, of information signals, is such that the said delay time is, for any one remote station, liable to vary over time from an initial value (Tri) such that the positioning signal is not necessarily received within the said window (Tf), and the said emission of positioning signal is then, for any one remote station, liable to be repeated, until the said positioning signal is actually received by the central station within the said window. … …

Abstract: The network includes a central station which transmits digital words to a local station in multiple frames (MF') made up of frames (F'1-F'N). After each frame is set, there is a zero level interval (DMW'). Each frame is divided into sub-frames (SF1-SF43) containing an octet of information. Each local station transmits one or more sub-frames. The frames are under-utilised, to allow for the zero level interval. A time shift can be introduced between the frames to provide a single free interval for each frame.
