7 Testing TDR

This section describes the procedure to test cable faults: open or short.

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

Note: OA TC-1 tests done at C&S tests are for open and short cable fault test cases. Also TDR is usually run to find the root-cause when there is no link. The test procedure described in Section 7.1 has an extra step over the compliance test procedure: to force link-down condition when possible (use if required).
