Abstract

The invention concerns a method of establishing a multichannel connection comprising N channels, two switching facilities, a communications network, and a transmit-side and a receive-side access facility to a communications network. When a multichannel connection (SLOT3, SLOT7; SLOT5, SLOT28) is established through a switching network (DSN), first the transit times (T1, T2, T3) of more than N channels through the switching network (DSN) are determined (MONIT). Then N channels are selected from said more than N channels by means of an algorithm (CONTR), which uses the determined transit times (T1, T2, T3) as input values. Subsequently the selected N channels are assigned as channels to the multichannel connection (SLOT3, SLOT7; SLOT5, SLOT28), and for their synchronization the channels are delayed in accordance with the determined transit times (T1, T2, T3). This method is also applicable to end-to-end multichannel connections and single channel connections.
