Abstract

Line bundles (LB1 . . . 4) containing combined narrowband connections to be switched between time division multiplex communication systems (KS) are converted into a cell-oriented information stream (IS). A predetermined number of the line bundles (LB1, LB2) is switched via permanent virtual connections (PVC1, PVC2) of an ATM communication network (KN). Switched permanent virtual connections (SPVC1, SPVC2) are set up in the ATM communication network (KN) for the switching of additional line bundles (LB3, LB4). The switched permanent virtual connections (SPVC1, SPVC2) are respectively set up and dismantled in dependence on the traffic volume (VB) between the communication systems (KS). The switching-oriented resources of the ATM communication network (KN) are used more efficiently, and the ATM network switching costs are reduced.
