Abstract: The present invention provides an apparatus, system and method of increasing port availability for a communication switch. First, second and third M port crossbars are arranged to provide a crossbar with a increased number of ports available for the communication switch. K ports of a first M port crossbar are individually coupled to K ports of a second and a third M port crossbar via interconnect buses. Further, K ports of the second and third M port crossbars are individually coupled via interconnect buses resulting in L available ports on each the M port crossbars in which M>L>K.

Abstract: A technique for embedding a first clock phase within a second signal is described. In one embodiment, the invention comprises a method of embedding a phase of a first signal within a second signal comprising the steps of monitoring a first signal for a frame event, responsive to detection of a frame event in the first clock signal, determining a position of the frame event relative to a current segment of a second signal, and embedding in the current segment of the second signal a value representative of the relative position of the detected frame event.

Abstract: An apparatus and system is provided for coupling an ethernet switch to communication link(s) in a communication network without requiring the disconnection and reconnection of the communication link(s). A module is configured to accommodate components of an ethernet switch, and can be modularly introduced into a communication rack and quickly engaged with rack-mounted mating connectors which are coupled to the communication link(s).
