Running Video-DSL Rate Prediction Tests and Viewing Results
³
WB Long. Balance measures the wide band longitudinal balance of
the broadband service.
³
WB PSD Noise measures the wide band power spectral density noise
on the line.
³
WB Attenuation measures the cable length value from wide band
attenuation tests.
³
WB Impulse Noise measures values from the wideband impulse
noise tests.
³
Data Rate Test predicts the maximum bit rate achievable on the
local loop based on Annex, Technology, and Target SNR selected.
³
HD Streams is the number of high definition streams carried on the
local loop. Again, the pass indicator is displayed only if the analyzed
number of HD streams matches the number set on the Configuration
tab. Otherwise the status is fail.
³
SD Streams is the number of standard definition streams carried on
the local loop. Here, the pass indicator is displayed only if the analyzed
number of SD streams matches the number set on the Configuration
tab. Otherwise the status is fail.
³
Predicted Rate displays the downstream and upstream predicted
data rates.
