causes: Either a SFP has been installed but the license 
key does not include SFP fiber support, a fiber link 
could not be established even though no LOS was detected 
(i.e. an optical carrier was detected, which could be due 
to a broken TX fiber, or because the link is disabled at 
the fiber link partner), a fiber link could not be 
established and LOS is detected (i.e. no optical carrier 
is detected), the installed SFP is not supported or the 
installed SFP failed to initialize correctly. NB: a

 value indicates that the master and slave 
ends of a link are different hardware products, or have 
different software versions, or have different TDD Frame 
Configuraton Modes (Standard/Expert) in HCMP topology. 
NB: It is very unusual to detect this, because 
incompatible units will normally fail to establish a 
wireless link. However, some combinations may establish a 
partial wireless link and detect this situation. NB: A

may cause interference with other links in a synchronized 
network. Timing System Failure is an early warning, 
indicating that 80% of the holdover period has expired.
