ABSTRACT:
Point-to-multipoint connections, which are connections from one transmission/reception equipment to a plurality of transmission/reception equipment, can be accomplished by a virtual chain of connections being set up in which, preceding from the first transmission/reception equipment, message cells are sent to a group of a plurality of transmission/reception equipment, the messages are duplicated in the first transmission/reception equipment of the group of the plurality of transmission/reception equipment, and the messages are then sent through the ATM switching network to the next transmission/reception equipment of the group. This procedure is repeated in the further transmission/reception equipment until the end of the virtual chain connection is reached, the end being the last transmission/reception equipment of the group of the plurality of transmission/reception equipment.
