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.
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).
