A meshed backplane has dedicated pairs of connections for high-speed serial connection in each direction between each of multiple application modules and each other application module. A management/control bus is provided for out-of-band signaling. The mesh of serial differential pairs may be used for management/control bus signals when necessary. A time division multiplexing fabric is also provided for telephony applications. A star interconnection region is provided for distribution of signals from redundant clocks.
