Abstract

A telecommunication system comprises primary and secondary telecommunication means (21, 22) which through interposition of a telecommunication connection are mutually linked together. In this case the telecommunication link comprises a power cable (30), for instance from a network for electricity distribution. Such a power cable (30) comprises an external jacket (31) which at least encompasses one power conducting lead (R, S, T, N). The lead (S) is coupled to the telecommunication means (21, 22, 40) in order to transfer the telecommunication signal. In conformity with the invention the telecommunication means (21, 22, 40) are coupled with aforementioned lead (S) and with the external jacket (31) of the power cable (30) in order to present the telecommunication signal in between them. Thus a high quality asymmetrical signal transport is obtained which enables the presentation of telecommunication along an existing electricity network.
