Abstract
A method of allotting the signal links and routing the signal messages in the signalling transfer points of a common channel signalling system which are level type signalling transfer points for carrying out message transfer functions based on the common channel signalling No. 7 protocol of the ITTCC. Each signalling transfer point includes a signalling link selection value composed of a number of bits, signal data links, signal links, signal network functions, clusters and groups, connected in such a manner that a signalling transfer point includes a certain number of signal network functions, each signal network function including a certain number of signal links, each signal link being connected to one signal data link. The signalling transfer point includes a number of clusters of signal links (equal to the number of signal network functions) grouped in a plurality of clusters (equal to the number of signal links). In this system, if a level has a malfunction, replacement levels are available, and the determination as to which cluster has the replacing level can be easily made. As a result, it is always possible to carry out the functions of the signalling transfer point, so lo…
