Default severity	minor
Source stream	main
Message format string	FEPL failure is declared
Cause	FEPLF (Far-End Protection Line Failure) notification is generated based on SF (Signal Failure) condition on the protection port in the received K1 Byte.

Cause	APS switchover between working port (channel 1) and protection port (channel 0) can happen due to change of status of any port or user-initiated switch commands on any port.
Effect	Traffic is transmitted to and received from the other channel/port.
