Abstract

Unit for coupling a start and stop terminal with a data network to connect a telex terminal transmission equipment with a synchronous data network comprising means for modulating a transmission network pulse current with telex elements so that a sequence of "1" corresponds to a telex element of one polarity or level and a similar sequence of "0" corresponds to the other polarity or level, means to examine the modulated pulse current to determine a specific modulation change in the telex equipment., means for counting in the pulse change of the pulse modulated current to determine the duration of each pulse sequence corresponding to a telex element, means for scanning at least one predetermined pulse position in each sequence and means for deriving from a group of pulses thus scanned from a series of successive pulse sequences a group of data bits to form a character of d atos.
