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 TC1 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).
