7 Testing TDR

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

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

Note: OA TC-12 tests done at C&S tests are for open and short cable fault test cases. Also TDR is usually run to find root-cause when there is no link. Test procedure described in next section has an extra step over compliance test procedure: to force link-down condition when possible (use if required).
