Gbps for one SNTT. If the DUT supports 3.0 Gbps signaling, it is expected to the same.
10. The Testing Station is then instructed to transmit D.C. Idle for one RCDT. The DUT is
expected to do the same.
11. The Testing Station is the instructed to transmit its Phy Capabilities bits indicating
support for all speeds. The Testing Station is instructed to indicate that it supports all
speeds and SSC settings. The DUT is expected to transmit it's Phy Capabilities Bits.
12. The Testing Station is instructed to transmit D.C. Idle for one RCDT. The DUT is
expected to do the same.
13. The Testing Station is instructed to then transmit properly formatted TRAIN patterns at
the highest mutually speed (6.0 Gbps, SSC). The DUT is expected to do the same.
14. Upon successful reception of a properly formatted TRAIN pattern from the DUT, the
testing station is instructed to not transmit a TRAIN_DONE pattern. The DUT is
expected to receive the properly formatted TRAIN pattern and being transmitting
TRAIN_DONE patterns.
15. Upon expiration of the MTWT timer, the Testing station is instructed to stop transmitting
TRAIN patterns and begin Transmitting D.C. Idle for one RCDT. The DUT is expected
to do the same.
16. After RCDT, the testing station is instructed to transmit properly formatted TRAIN
patters at the next highest mutually speed (6.0 Gbps, No SSC). The DUT is expected to
do the same.
17. Upon successful reception of a properly formatted TRAIN pattern from the DUT, the
testing station is instructed to transmit TRAIN_DONE patterns. The DUT is expected to
do the same upon reception of a properly formatted TRAIN pattern received from the
testing station.
Observable Results
●
Verify that the DUT transmits at least one TRAIN pattern and at least four
TRAIN_DONE patterns at 6G with SSC before MTT has expired. Verify that the DUT
waits one RCDT and participates in the second Train-SNW with the testing station.
●
Verify that the DUT transmits at least one TRAIN pattern and at least four
TRAIN_DONE patterns at 6G with no SSC before MTT has expired.
Possible Problems
●
Lower level testing will have to be used to verify that the DUT enabled SSC properly.
