Testing and Maintaining an RIO Network
890 USE 101 00 October 2006 133
Test 6 Time Domain Reflectometer (TDR) Test
Performed on all drop cables and at all trunk end points. It tests the integrity of all
drop cables up to and including the tap port, as well as the trunk cable components.
Results are produced on a strip chart record with the location of impedance
mismatches and the extent of the impedance mismatch. The specification limit for
any TDR measurement is determined by the cause of the mismatch.
Test 7 Attenuation Sweep Test
Tests the ability of the cable system to pass RIO signals without degradation over
the full bandwidth. The test is conducted from the RIO processor node to all trunk
and drop end points.
