摘要

Route search method in a centrally controlled electronic control center system, to search the route through a telecommunication switching device, particularly in telephone exchange systems, in which the condition of the line of the links is stored in a central storage through a binary key (for example "1") for the condition of "captured" or through another binary key (for example "0") for the condition of "free", characterized in that the storage elements associated with the output of a switch block are successively checked through a checking circuit until a storage element containing the other binary key is found, or until it is determined that all the storage elements contain the one binary key and by that in a case, when a storage element is found, the associated link is free, the route search continues in those elements of storage to which associated links leads the free link that has just been found, in the next switching step and because in the other case, if all the storage elements belonging to the outputs of a switch block contain the binary key for the "fetch" condition continues the route search in the storage elements associated with the preceding switching step and in said switching step the next storage element is determined whose associated link is free and because in both cases the connection possibility of the The link associated with the storage elements is deduced from the common store of the line condition of a link and the addresses of the storage elements of the line condition of the links connectable with said link.
