Abstract

According to a prior patent application, the digital user data signal is transmitted in CMI code and, when the code is generated, a binary signal content of the auxiliary signal is allocated to one of the element combinations excluded according to the CMI code rule. Only the start of a one bit or zero bit of the auxiliary signal is marked, so that needle pulses occur at the receiving end at comparatively large intervals only, which pulses are adequate for transmission of the auxiliary signal but severely impede generation of a clock signal at the receiving end. According to the invention, a combination signal is therefore transmitted which contains a clock pulse pattern for simple generation of a clock signal at the receiving end. <IMAGE>
