Testing IOP: Link-up and Link-down

OA TC-1 specifies different PHY level tests to test link-up time, link-down time, and link stability. 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.

TC-1 interoperability tests are carried out by OA compliance test house C&S. To test interoperability of DP83TC81x, C&S tests each of these parameters with DP83TC81x and other 100Base-T1 certified PHYs as its link-partners. Each of these parameters are tested for a large number of iterations over different temperatures and cable lengths.

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