Abstract

In the known injection of an auxiliary signal during the re-coding of the binary user data signal into a path code, the control voltage of a clock phase-locked loop is also amplitude-modulated in the transmission-end code converter, so that the clock signal generated and the user data signals sent onto the transmission path are phase-modulated. The limited phase shift restricts transmission capacity for the auxiliary signal, and furthermore interference of the user data signal may occur due to the generated phase jitter. According to the invention, the user data signal is therefore transmitted in CMI code and, when the latter is generated, a binary signal content is assigned to at least one of the element combinations excluded by the CMI code rule, and only the start of a one bit or a zero bit of the auxiliary signal is marked. <IMAGE>
