Abstract
In a digital transmission of plesioquinous pulse sequences with positive-negative stuffing, additional information must be transmitted which contains stuffing information, and also an information bit in the case of negative stuffing. Falsification of the additional information due to double and multiple errors is possible when the additional information includes adjacent bits. This error source is eliminated by the fact that every additional information is transmitted serially, forming a stuffing frame, together with a stuffing frame identifier. The additional information occurs in the first time slot of the sixteenth channel in the second, eighteenth, thirty fourth, fiftieth, etc. basic frame. <IMAGE>
