    POTS Testing and Fault Location The POTS Toolbox Splits Test The Splits test should be run if an Opens Test result shows a “Possible Split or Water” condition. However, a split condition may exist that is not detected by the Opens Test, due to the length of the split being fairly short. In this case, when the pair is known to be split but shows to be good and balanced, you should run the Splits Test.
  • Page 84 990DSL Users Guide Notes The “Possible Split or Water” result is generated whenever the 3T Capacitance Ratio (TG to TR) of a balanced pair is greater than the average ratio for the selected Cable Type. This may be due to either a split pair condition, enough water in the cable to alter its 3T Cap.

    990DSL Users Guide Comparing Parametric Tests to the TDR Test Table 6-1 provides an overall assessment of the accuracy of the TDR test and three parametric tests (Opens, Load Coils, and RFL) at locating six common cable faults. The table highlights both the versatility of the TDR test as well as the complementary nature of all of the tests and their relative strengths and weaknesses.

    TDR Testing and Fault Location What Happens During a TDR Test: An Overview What Happens During a TDR Test: An Overview You can use the TDR test to determine the length of a cable and to precisely locate faults along the cable. When making a TDR measurement, the CopperPro applies a balanced, high-frequency drive pulse to the test pair.
