Figure 3.10.3­2: Quality Voltage Graph
· Quality Voltages between 3.0V and 3.3V indicate PRE and POST FEC error­free wireless
link.
· Quality Voltages between 2.0V and 3.0V indicate a low rate of errors that the forward error
correction will correct. The lower the voltage, the more errors are being corrected.
· Quality Voltages between 0.3V and 1.7V indicate excessive PRE­FEC errors in the wireless
link, some of which cannot be corrected by the FEC. To indicate this change in error
performance, the quality voltage will drop from 2.0V to 1.7V in a single step.
· Quality Voltages below 0.3V indicate an unlocked deframer condition. This will be
recognized as a link­down condition.
