Abstract
In a digital telecommunication network containing bearer channels between switching nodes, the method of building-up a routing address consisting of routing words that are associated with the switching nodes and via which the transmission of information packets is effected in accordance with the routing address contained in each packet, and for their storage in the region of a called subscriber, dispatching a build-up packet from the first calling subscriber which contains the location-independent call number of the called second subscriber, each switching node retransmitting to other switching nodes connected to it at least the first of several successively received build-up packets having the same call number and whose routing address does not exceed a specific length and adding to each build-up packet retransmitted a routing word associated with the bearer channel connected to it and forming a part of the travel path of the build-up packet, the called subscriber designated by the call number or the switching node connected directly to the called subscriber receiving at least one build-up packet intended for it and storing ar least one of the routing addresses built-up by the bui…
