Test procedure
1 The Link Training State machine of the tester is set to
'Sleep' and then to 'Poll'. After 300 ms, the link state
of the DUT is expected to be 'Initialized'.
2 After another 1000 ms, the DUT is expected to be still
in 'Initialized'.
3 The DUT is requested to switch to link state 'Arm'
and expected to transition into this state.
4 The generator is set into link state 'Arm' and the DUT
is requested to switch to link state 'Active' and
expected to transition into this state.
5 The DUT is requested to switch back to link state
'Arm' and expected to transition into this state.
6 The DUT is set back to link state 'Active'. The tester
is then set into link state ‘Down’. Because the link is
up, the link state of the tester switches to 'Initialize'.
The DUT is expected to switch to state ‘Initialize’ as
well.
