A combined multimedia and data network system is usable with at least one asynchronous device and at least one isochronous device. The system includes a target system having first and second network environments. A multiwire cable is connected to the target system. A connection system is coupled to the cable. The connection system has a single unit containing a plurality of hubs and a plurality of bridges. Each of the network environments is coupled to a respective one of the hubs and a respective one of the bridges. The cable carries data and multimedia signals in the first and second network environments in parallel from the target system to the first and second connection devices, respectively.
