The LTSSM Overview pane can display LTSSM transition, state and EQ data, for both upstream as
well as downstream link directions. However, this display depends on how you configured the
direction of data capture (upstream, downstream, or bidirectional) in the Connection Setup tab of the
Setup dialog box of the U4301A/B module. For instance, if you configured a bidirectional data
capture using U4301A/B, then LTSSM states are displayed for both directions.
Using the LTSSM Overview pane, you can view the LTSSM transitions, states and EQ, during events
such as:
