errors indicate a problem with the RF
link. Refer to the
Troubleshooting Guide
on page 119 of this manual for more details on troubleshooting
the causes of errors.
The ODU and link error counts for the most recent 24 hours are recorded in 15-minute increments and
displayed on the right side of the page. The left side of the page displays the 24-hour totals for the most
recent 7 days.

Figure 9 shows the TRACER RF Link Max/Min Received Power History page, which displays the
available received power statistics from the system. Minimum and maximum received signal levels for the
RF link (from both the local and remote TRACER units) in 15-minute and 24-hour increments are found
on this screen.
Figure 9. RF Link Max/Min Received Power History
The received power level (
MIN
and
MAX
) represents the minimum and maximum values of received signal
levels in 24-hour or 15-minute increments, and is displayed as a numerical value in dBm.
Press <n> to view the next 8-hour segment of 15-minute totals and <p> to view the
previous 8-hour segment.
Real-time signal values are not supported on all TRACER 6420 systems. Systems must be
ADTRAN calibrated to provide readings for Rx or Tx Power signal levels. For
uncalibrated systems, the received power level is displayed as a numerical value from 0 to
100 where 0 corresponds to 0V RSSI and 100 corresponds to 5V RSSI.
The minimum receive power level is recorded to aid in troubleshooting problem RF links.
Radio links with high
MIN
numbers and intermittent performance are probably
experiencing interference, while links with low
MIN
numbers have improperly engineered
paths or excess system losses. A system with
MIN
numbers varying widely could indicate
fading, reflections, or an intermittent installation problem such as loose connectors,
damaged coax or lightning arrestors, or water contaminated feedlines.
