Video Results
This category reports the total number of active video streams and provides the combined total data
rate associated with the ATM Video Virtual Channel selected when configuring the ADSL interface
or the Ethernet port used in the Ethernet mode. The screen provides a quick summary of the total
data rates for all of the video program flows present on the interface under test.
The total video bandwidth (data rate) peaks can be important in analyzing total bandwidth available.
The total bandwidth is found on the ADSL Summary screen. The difference in the two numbers is
the bandwidth available for either Internet data or Internet data and VoIP data.
Table 42 describes the video results.
Optical power results
The optical power is displayed as dBm or mW (depending on your selection on the Setup menu)
along with the Min, Max, and Average. The wavelength is displayed just under the power measure-
ment.
If using relative measurement mode, the received signal is compared to the reference value, and
displays the difference in dB. NOTE: If no reference value has been stored, 0.00 dBm will be used
as reference value.
Copper results
The copper results are described in the tables below.
AC voltage
You measure AC volts to:
Delay Stats The current latency and the maximum latency since the stream became active.
(Latency is the time to complete a program change, in
milliseconds.)
Rate Stats
Reports individual bit rates for each portion of the video stream. The “IP
Total” statistics measure the bandwidth used by the video stream,
including the UDP and IP headers.
Table 42 Total video rates results
Result Description
Active Streams Number of active streams
Current Combined Rate The combined rate at this moment.
Maximum Combined Rate The maximum combined rate seen since the start of the test.
Average Combined Rate The average of all combined rates.
