This is the preset hint being
sent by the BERT to the DUT
during phase 0 of the link
equalization procedure. This
is only used when the BERT
operates as an upstream
device.

This is the preset the BERT
transfers to the DUT in
phase 0 of the link
equalization procedure. This
is only used when the BERT
operates as an upstream
device.

This is the preset the BERT
requests the DUT to switch
to during link equalization.
Dependent on the role the
BERT is playing, this is done
in either phase 2 or 3 of the
link equalization training.

BERT's TX port should use
user-calibrated presets or
