ABSTRACT:
For packet-data switching in the ISDN D channel through a digital exchange, the need for a costly frame handler for processing OSI Layer 2 and 3 functions is to be eliminated; in response to destination information in the SET UP message, an OSI Layer 3 control unit (SE3) establishes a connection between the two OSI Layer 2 control units (SE1, SE2) of the exchange (VST), to which the data terminals (DEE1, DEE2) are connectable and direct packet-data transfer can then take place between the OSI Layer 2 control units without further participation of the Layer 3 control unit.
