Abstract: In a process for laying a cable, or a protective sheathing for a cable core to be introduced into the protective sheathing at a later time, in a sewage pipe, the cable or the protective sheathing is fixed at particular spacings along the inside wall of the sewage pipe by means of clips. Here, the cable or the protective sheathing is diverted in the region of house lead-ins, so that the cable or the protective sheathing by-passes the house lead-in. The mutual spacing between the clips is substantially smaller in the region of the diversion than in the region of the straight path of the cable or the protective sheathing. The cable or the protective sheathing is anchored in the shafts and is pre-tensioned with a force of at least 250 N.

Abstract: A communications cable network, in a duct or tube system used primarily for other purposes, wherein the communications cables are mounted on the walls of the duct or tube system. The communications cable (3), is made of a core (7-10) and a sheath (11). The core (7-10) of the communications cable (3) is extremely flexible and the sheath (11) is sufficiently rigid that cable sag is less than 20 mm for a 2000-mm distance between fastenings. The sheath (11) is removed from the core (7-10) in the area of the shafts (2) of the duct or pipe system (1).
