6 MaxTester DSL Test
Results
The MaxTester DSL is designed to make xDSL turn-up easy. The unit will emulate an
ATU-R to the point that it can handshake and connect with an ATU-C and report the
upstream and downstream parameters. Simply connect to the line, turn on the
MaxTester DSL, and select a test to run. Results obtained include upstream and
downstream throughput and noise margin.
xDSL Connection Summary
The
Connection Summary
tab allows you to view the pass/fail status and details of
the test results.
³
Line Status
displays the status of the line under test
during negotiation with the DSLAM. The value
changes from Idle /Activate /Handshake /Training
/Showtime for ADSL2+ or VDSL2 mode.
³
Operation Mode
is the xDSL mode of operation as
negotiated between the unit and the DSLAM.
³
Downstream/Upstream SNR
is a value ranging from 0
through 63.5 for the minimum SNR (signal-to-noise
ratio) margin.
³
Downstream/Upstream Max Bitrate
displays the D/S
(downstream) and U/S (upstream) maximum
attainable bit rates that the circuit can handle as
determined by the remote terminal and CO during the
training phase. Values can be greater than the actual
bit rate.
³
Downstream/Upstream actual bit rates are displayed by graphic bars and the
current actual values appear as numbers.
³
Downstream bit rate value is shown in yellow region if it is greater than Min
threshold and less than OK threshold.
³
Upstream bit rate value is shown in yellow region if it is greater than Min
threshold and less than OK threshold.
³
Downstream bit rate value is shown in red region if it is less than
Min threshold.
³
Upstream bit rate value is shown in red region if it is less than Min threshold.
