Abstract
The invention relates to a method of transmitting digital data between a digitally operating subscriber station and the subscriber concentrator of a PCM/TDM telecommunication network via a two-wire trunk line at a lesser signalling bit rate than on the TDM highways of the network. Information blocks are transmitted in both directions with at least two PCM words which correspond to successive information samplings of the digital data.
Claims1
A method for transmitting digital data between a digitally operating subscriber station and the subscriber concentrator of a PCM/TDM telecommunication network via a two-wire trunk line at a lesser signalling bit rate than on the TDM highways of the network, wherein the improvement comprises alternately transmitting in both directions of transmission information blocks with at least two PCM words which correspond to successive information samplings of the digital data.
