When the APS FSM detects a failure of one of the Worker lines, e.g., line #2 in
cross connect of the Protection PHAST-12N performs a protection bridge connecting the
transmit protected traffic of the failed line to the transmit Protection line. The Worker PHAST-
12N 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.
