Auto CQ/Video-DSL Rate Prediction
Copper Test Module 51
Running Video-DSL Rate Prediction Tests and Viewing Results
Video Rates
The Video Rates tab allows you to view the pass/fail status, details and
predicted data rate of the high and standard definition streams carried on
the local loop.
Configurable parameters include:
³
No of Streams is the number of
High Def. (definition) streams,
ranging from 0 to 4 and Std.
(standard) Def. streams ranging
from 0 to 10.
³
Stream Rate (Mbps) is the High
Def. (HD) and Std. Def. (SD)
stream rate before running the test,
ranging from 0 to 24 Mbps. Default values are 8 Mbps for HD and
1 Mbps for SD.
³
Technology lists the following values: ADSL2+, ADSL2, or ADSL. If
Annex L is previously selected, ADSL2 is automatically set. If Annex M,
ADSL is not available.
³
Annex defines the modes of available ADSL Annexes from the
ITU standards.
³
A is ADSL service functioning over POTS.
³
B activates the ADSL functionality over ISDN.
³
L Mask 1 assumes an increase in ADSL2 range/distance.
³
L Mask 2 also extends the signal reach but can show an
improvement in the upstream data rate.
³
M allows increased upload speeds from 1 Mbps to 3.5 Mbps.
Available only for ADSL2 and ADSL2+.
