    摘要： A telephone line interface and side-tone attenuation circuit includes two opto-electric converters. The first has an input interconnected to receive a signal proportional to a near-end signal, and an output interconnected to modulate a current proportional to the near-end signal onto the subscriber loop. The second has its input interconnected to provide a signal proportional to a current on the subscriber loop, including the current proportional to the near-end signal, at its output. A summing amplifier receives signals proportional to the output voltage of the second opto-electric converter and a signal proportional to the near-end signal. The output voltage of the second opto-electric amplifier includes a component that is substantially 180° out of phase with the near-end signal, allowing the near-end signal to be cancelled at the summing amplifier.

    摘要： A power feed control arrangement used for feeding in power several circuits TL0-3 all integrated on a same chip. The circuits are used to supply U-interfaces of ISDN telecommunication lines. The arrangement is provided with a temperature sensor (TS) and each circuit has an over-current sensor (IS0/3) and is provided with a power feeder (PC0/3) able to couple it to a power supply (PS) in response of a power request signal (PF0/3). The power feeders are further controlled, via a power feed controller (PFC), by the sensed temperature and over-currents. Four temperature ranges ( 160°C) are defined where the power request signals are either used to start-up the circuits in sequence - in case of simultaneous requests- , are ignored, or are used to disconnect some or all of the circuits. A not-acknowledged or status signal (NACK0/3) is also provided by the power feed controller (PFC) for indicating the power status of the corresponding circuit (TL0/3).

    摘要： A device (1) for protecting a telecommunications apparatus against an abnormal transient voltage signal received via a telecommunications line (2, 3) comprises means (16, 18, 20, 22, 26) for selectively suppressing the transient voltage signal from other normal communications signals. The suppression means (16, 18, 20, 22, 26) are responsive to the frequency of the transient voltage signal rather than its voltage. Overvoltage protection means (12, 14) may also be provided for suppressing transient and continuous overvoltage signals present on the telecommunications line (2, 3).
