5 Testing IOP: Link-up and Link-down

OA TC1 specifies different PHY level tests to test link-up time, link-down time and link stability. Similar ECU level tests have been highlighted in OA TC8. This section highlights the test sequence used for these IOP tests for PHY level testing and the same can be ported for ECU level tests.

TC1-interoperability tests are carried out by OA compliance test house C&S. To test interoperability of DP83TC811, C&S tests each of these parameters with DP83TC811 and other 100Base-T1 certified PHYs as its link-partners. Each of these parameters are tested for large number of iterations over different temperatures and cable lengths.

Detailed IOP test report from C&S with OA compliant results is available on request.
