“twister” 2131 Multimode-to-Singlemode Media Converter 7
Set the LLCF Switch
Link Loss Carry Forward (LLCF) Switch.
The MM-to-SM media converter incorporates Link Loss Carry Forward
(LLCF) functionality as an aid in troubleshooting a remote connection.
A switch for enabling/disabling LLCF is located on the rear panel of the
converter. When LLCF is enabled, the FX ports on the “twister” media
converter do not transmit a link signal until they receive a link signal from
the opposite port. Refer to the page titled “Link Loss Carry Forward” in the
User Guide section of this manual for more detailed information.
The unit is shipped with the LLCF disabled. To reset the LLCF, simply slide
the switch to the appropriate setting.
