ABSTRACT:
For the transmission of data signal bits occurring with a first bit rate from a transmission device by way of a transmission link to a receiving device in a bit stream having a second bit rate which is higher in comparison to the first bit rate, the data signal that is to be transmitted are combined in the transmission device with additional filler bits to form envelopes respectively comprising a prescribed plurality of bits, this being executed given non-transgression of the prescribed bit rate difference between the first bit rate and the second bit rate. The envelopes are transmitted via the transmission link with the second bit rate. Given transgression of the prescribed bit rate difference, the data signal bits, with first bit groups identifying the same as belonging to data signal envelopes, are combined with bits of separate envelopes which respectively contain a second bit group identifying them as blank envelopes and are transmitted via the transmission link with the second bit rate.
