Remote Signaling
The BayStack 10BASE-FL RDN Media Adapter supports remote
signaling to indicate a far end receiver failure/remote fault
detection. Bay Networks uses a proprietary version of remote
fault signaling, because remote signaling is not specified in the
IEEE 802.3 10BASE-FL standard. Remote signaling is used to
verify the connection status of both the transmit and receive
fibers.

A Rem LED on the media adapter indicates remote signaling
