IFS MC201-1P/1FS User Manual 5
LLCF (Link Loss Carry Forward) detects the connection loss
on the TP line, and LLR (Link Loss Return) detects the
connection loss on the fiber line.
Link Loss Carry Forward (LLCF)
The MC201-1P/1FS incorporates an LLCF function for
troubleshooting a remote connection. When LFP function is
enabled, the FL/TP ports do not transmit a link signal until they
receive a link signal from the opposite port.
The diagram below shows a typical network configuration with
a good link status using MC201-1P/1FS for remote
connectivity.
In case of a connectivity issue, the MC201-1T/1FS media
converter LLCF sends the notification to the switch/hub that
generates a trap to the management station.
* The default is set to OFF for LFP function.
