After CML Subsystem processing eight 77.76 MByte/s STS12 channel byte streams are
transmitted on the parallel data bus synchronous to REFCLK on the line side (or 16 on the
system side)
Every one of the eight/sixteen 77.76 MByte/s STS12 receive channels carries a serial bit-stream
received from the differential RASIO™ CML pads. In Figure 70, the receive serial lines are
generalized as “RX P/N.”
