Figure 3.10.32: Quality Voltage Graph<br />
· Quality Voltages between 3.0V and 3.3V indicate PRE and POST FEC errorfree wireless<br />
link.<br />
· Quality Voltages between 2.0V and 3.0V indicate a low rate of errors that the forward error<br />
correction will correct. The lower the voltage, the more errors are being corrected.<br />
· Quality Voltages between 0.3V and 1.7V indicate excessive PREFEC errors in the wireless<br />
link, some of which cannot be corrected by the FEC. To indicate this change in error<br />
performance, the quality voltage will drop from 2.0V to 1.7V in a single step.<br />
· Quality Voltages below 0.3V indicate an unlocked deframer condition. This will be<br />
recognized as a linkdown condition.<br />
