ABSTRACT:
A path routing arrangement to perform path routing operations for wideband communications between subscriber terminals of a communications system is disclosed. To enable such communications the invention incorporates principles of frequency division to allow communications carriers to share a common transmission path, a plurality of which transmission paths may be selectively defined through a branched path path routing arrangement, desired paths being so defined to allow bi-directional carrier transmission between calling ones and called ones of the subscriber terminals.
