DSL/IP Connection Summary

Operation Mode is the xDSL mode of operation, bonded or
non-bonded, as negotiated between the unit and the DSLAM.

Downstream/Upstream SNR is a value ranging from 0 through 63.5 for
the existing SNR (signal-to-noise ratio) margin.

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.
If the Operation Mode is bonded, the 2-DSL line Max Bitrate is
combined.

Downstream/Upstream actual bit rates are displayed by graphic bars
and the current actual values appear as numbers.

Downstream/Upstream bit rate values are shown in yellow region
if they are greater than Min threshold and less than OK threshold.

Downstream/Upstream bit rate values are shown in red region if
they are less than Min threshold.
If the Operation Mode is bonded, the actual bit rate is a summary of
both DSL lines.
