When the APS FSM detects a failure of one of the Worker lines, e.g., line #2 in
cross connect of PHAST-12P #2 performs a protection bridge connecting the transmit
protected traffic of the failed line to the transmit Protection line. PHAST-12P #1 performs the
protection switch. It connects the protected traffic of the failed line to the payload of its
associated received Protection line available at the Receive APS Port interface. The
unprotected extra traffic of that Protection line is no longer available and will be squelched.
