Abstract
An arrangement for switching broadband ISDN (B-ISDN) packets is disclosed. The arrangement comprises a broadband packet switch connected to B-ISDN customers and to a narrowband switch via an interface unit. B-ISDN control packets are connected by the broadband packet switch to the narrowband switch which transmits them to a control unit. The control unit responds to control messages by controlling the broadband packet switch to selectively interconnect B-ISDN customers and by controlling the broadband packet switch, the interface means and the narrowband switch to selectively interconnect B-ISDN and narrowband customers.
