A broadband packet switch arrangement comprising a broadband packet unit connected to a plurality of customer lines and a video switch for selectively connecting packetized video signals from a plurality of video sources to the customer lines. The broadband packet switch unit selectively connects customer lines and transmits received control packets received from the customer lines to a control unit which responds to video request packets by controlling the video switch to connect selected video packets to the customers lines. Each customer line includes a selector circuit which receives video packets and inter-customer broadband ISDN packets and merges them onto the customer line. After the control unit has granted permission to connect a video source to a customer line, video source change requests for the line are sent directly to the video switch which responds thereto by connecting a requested video source to the customer line.
