Abstract
The invention relates to a method for limiting the number of build-up packets during the process of building-up a routing address for the subsequent transmission of address-coded packets, the addresses of these packets being this said routing address, from a first to a second subscriber of a digital telecommunication network. This network comprises a plurality of switching nodes, a plurality of subscribers, a plurality of bearer channels connecting each switching node with at least one other switching node and with no subscriber, or with one or more of said subscribers, a plurality of routing words individually assigned to the bearer channels and a plurality of call numbers individually assigned to the subscribers. During the process of building-up a routing address the first subscriber despatches a build-up packet containing the call number of the called second subscriber, said build-up packet received by a first switching node is retransmitted through all bearer channels connected to this switching node, such retransmission being continued at each switching node upon reception of each build-up packet, thus the number of build-up packets increasing rapidly within the network. The …
