Abstract
The present invention provides for communication of data to and from isochronous data sources and sinks. Preferably, a portion of bandwidth on the link is also dedicated to convey data to and from non-isochronous sources and sinks, as well as to permit conveying housekeeping information (such as information relating to data sources and destinations) and status and control maintenance information. A management port is included in the isochronous switching devices to allow monitoring or diagnostic access to the serial isochronous data stream to and from all physical layer portion connections. Accessing one connection's data stream does not affect normal operation of the other connections.
