Abstract
The present invention relates to a process for establishing point-to-multipoint connections (A14, A33, A34) and multipoint-to-point connections (B14, B15, B35) in a coupling field comprised of a number of stages (I, II, III), each with a number of switching modules (11-15, 21-25, 31-35). To that end, when there are switching modules (21-25) in at least one stage (II), and if, depending on their type, these switching modules are capable of simultaneously splitting point-to-multipoint connections (A14, A33, A34) and of coupling together multipoint-to-point connections (B14, B15, B35), the proposition is made to connect point-to-multipoint connections (A14, A33, A34) in switching modules (25) in which more inputs than outputs are already loaded with connections and to connect multipoint-to-point connections (B14, B15, B35) by switching modules (24) in which more outputs than inputs are already loaded with connections.
