    Abstract: The device for the phase realignment of ATM cells in an optical ATM switching node is associated with each input line (Fe) of node and includes means (RIC) for recognizing the beginning of a cell, means (VE) for evaluating the time shift between of a cell and a reference instant and for generating an error signal (ER) depending on the amount of time difference, and means (LR) for compensating the time difference, driven by the error signal (ER). The time difference compensating means (LR) includes a logarithmic optical delay line that is connected upstream of the means (RIC, VE) for recognizing the beginning of a cell and for evaluating the amount of the time difference.

    Abstract: Transmitter module for optical interconnections, comprising a metal container housing an optical emitting device, an integrated circuit containing the driving circuit of the emitting device and an optical fibre extending outside the container, the emitting device being mounted on a metallic ground area realized on the integrated circuit. The cathode is electrically connected to the ground area and the anode is connected to a second metal area, connected with the output of the driving circuit. The module uses a type of assembly which minimises problems due to the length of the connecting wires, to parasitic effects and to the effects of signal reflections due to impedance mismatching. It also requires reduced power for its operation and it is provided with a structure facilitating dissipation.

    Abstract: A PCM switching element intended to be used in digital telephone exchanges for the making of switching or concentration stages of whatever capacity can be controlled by a commercially available microprocessor and can be made as an integrated circuit. Structures consisting of a plurality of such elements are readily designed owing to the use of a "busy" bit associated with each outgoing PCM channel.
