6 Testing SQI

SQI gives the indication of signal quality on the copper cable.

OA TC-12 indicates that SQI values should decrease monotonically with increase in noise levels. We recommend to add extra hysteresis. Procedure for adding extra hysteresis is covered in this section.

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