Link Loss Carry Forward
Link Loss Carry Forward (LLCF) is provided as an aid in troubleshoot-
ing a remote connection. When LLCF is enabled, loss of the receive
signal at the copper port prevents the fiber port from transmitting an
idle signal onto the cable. Conversely, if the fiber port does not detect a
receive signal, the copper port will not transmit an idle signal.
When LLCF is disabled, the unit continually transmits idle signals on
both ports.
Warning: If LLCF is enabled on the Access ONU and there is no link
on the unit's copper port, you will NOT be able to manage the ONU.
