ABSTRACT:
In a method of transmitting digital signals using so-called pulse stuffing, in which plesiochronous (nearly-synchronous) data signals are transmitted in a main channel of a sum signal channel as synchronous data and in an auxiliary channel of a sum signal channel as additionl data together with stuffing data, it is proposed that the stuffing data should consist of phase words which contain, in digital form, the phase relationship between the sum signal and the plesiochronous data signals.
