ABSTRACT OF THE DISCLOSURE A telecommunications system for utilizing a telecommuni- cations exchange intended for transmitting digital informa- tion between a plurality of extensions for transmitting be- tween data terminals data information having different rates is provided. Word forming means at the extensions subdivide the data flow into words of given length, buffer means store a plurality of words before sending these out over the line, which is done with the bit rate given by the transmission system for digital information, and frame forming means form frame heading words which precede the frames and have a plurality of subsequent data words. The frame heading word includes a frame locking word for synchronization on the receive side and a frame length word for indicating the number of the subsequent data words. Counting means count the number of words in the buffer means and control logic controls transmission of data words and the frame heading word such that as soon as the heading word with information on the number of data words has been transmitted there fol- lows transmission of the data words from the buffer means, while the frame heading word by itself is transmitted con- tinuously if the buffer means is empty. On receiving the data signals, a comparison takes place between the incoming binary flow and the frame locking word in a frame locking means for determining the beginning of the frames, the data words are separated from the frame heading word with the aid of filter means, and the received data words are stored in buffer means for subsequent output in series form to the data terminal.
