Link Fault Signaling (LFS)
When the LFS DIP switch is enabled (#6), an alarm indicator will
illuminate to indicate when a cable has been severed or when some
other cause of disruption in service has occurred. The LFS function
monitors both copper and fiber segments for a total service report.
Line Loop Back Test (LLB)
Set DIP Switch 1 to “ON” to activate the LLB diagnostic test function. Use
the LLB function to check if the copper and fiber and fiber segments are
connected properly.
