Abstract
A backplane interface adapter with error control and redundant fabric for a high-performance network switch. The error control may be provided by an administrative module that includes a level monitor, a stripe synchronization error detector, a flow controller, and a control character presence tracker. The redundant fabric transceiver of the backplane interface adapter improves the adapter'"'"'s ability to properly and consistently receive narrow input cells carrying packets of data and output wide striped cells to a switching fabric.

13. A redundant switching system, comprising:
-
two switching blades, each switching blade having a plurality of cross points corresponding to respective stripes of serial data streams; and at least one blade coupled to each switching blade through a backplane connection, wherein said at least one blade includes a plurality of redundant fabric transceivers which can switch traffic between the cross points on the two switching blades.

14. A redundant fabric transceiver coupled to a bus interface adapter comprising:
-
one or more first ports that communicate similar data in a substantially simultaneous fashion, wherein each of said one or more first ports is coupled to at least one switching fabric module; a multiplexer that selects communication data from said similar data for transmission, for transmission wherein said similar data can include more than one version of said communication data; a downlink transceiver that receives, conditions, and transmits said communication data; and one or more second ports that receives said communication data once transmitted from said multiplexer, wherein said one or more second ports forwards said communication data to a bus interface adapter. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
