Network Status
The information about the condition of the network is presented in the form of
Network Status. This information indicates the loss of connection (the first break in
the self healing ring) and is similar to the way existing 140NOM21200 reports the
loss of redundant cable.
The break of the fiber cable will be detected by the module not receiving the signal
from the side where the cable is broken and will be reported as a Cable B Framing
error by MBPSTAT. This condition will also activate the FRNGoff LED on the front
of the module.
