Running a Send WB Tone Test
To run a Send WB Tone Test, do the following:

ADSL Auto-Test
The ADSL Auto-Test is a double-ended test that performs essentially the same
WB Loss sub-test included in the DSL Auto-Test described earlier in the
chapter, with
ADSL
yet comprehensive ADSL DMT (Discrete Multi-Tone) transmission test on the
pair, compliant with ANSI T1.413 standard frequencies. It provides the
following results:
•
Predicted Upstream and Downstream Data Rates achievable on the line.
•
Insertion Loss values at each ADSL DMT frequency (8 kHz to 1104 kHz).
•
Signal-to-Noise Ratio (SNR) values at each ADSL DMT frequency.
•
Encoded number of Bits / Tone at each ADSL DMT frequency.
The test requires another CopperPro or TN2100 "Terminator" at the far end of
the pair to act as the "Sending Unit". The units automatically communicate
with each other over the test pair, so you don't need a separate control pair.
