Optical Transmission Link Indictors:
The presence of Local Link (LLINK) on the front panel indicates that the
INCOMING optical digital signal is synchronized and being received
without errors. In order for ANY OTHER INDICATORS to be valid, the
LLINK LED must be illuminated GREEN.
The Remote Link Indicator (RLINK) indicates that the remote end’s
(relative to observer) optical digital signal is synchronized at the remote
end and is being received without errors. This indicator is not applicable
to this particular model because it operates in single direction. This
indicator requires bi-directional operation to become functional.
