Multi-channel transmission system in time-division multiplex technique with delay compensation devices

摘要

Using double-current pulses with exchanged phase angle for forward and return channel in the transmission system, and detectors, responding to the phase angle of the double-current pulses, in the delay compensation devices of the transmission system makes it possible to provide in each case only one delay section inserted into the transmission path for each forward and return channel, blocking elements controlled by the detector blocking the access to the delay section for pulses of the opposite direction.
