    POTS Testing and Fault Location The POTS Toolbox Adjusted Opens Test A cable manufacturer’s data can vary by as much as 7% among cables. Therefore, for greater accuracy, it is strongly recommended that you first perform an Opens test on a known good pair in the cable. This data can then be saved as a Custom Cable Type for further use on faulted pairs in the same cable.

    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 78: Splits Test: Connection Diagram

    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.

    TDR Testing and Fault Location The TDR Toolbox After determining the best set of parameters for the specific type of reflections that it detects, the CopperPro displays a continuous image of the waveform on the screen. If you want to see the effect of a different pulse width or filter, you can do so at any time, with the continuous test automatically displaying the resulting waveform.

    990DSL Users Guide acy73s.eps Figure 6-3. Pair 1 and 2 Compare Test Result Screen Pair 1is always depicted as the lower trace and shown as a solid line. Pair 2 is the upper trace, which is shown as a dotted line. In Figure 6-3, note that the trace for Pair 2 has a minor reflection (it is marked by the reflection cursor) that indicates a gauge change at a splice point.

    TDR Testing and Fault Location The TDR Toolbox Pair 1 waveform data is used as the reference, and Pair 2 data is subtracted from it to obtain the “difference” waveform. If both pairs are identical (have exactly the same waveforms), the result is a straight line with no reflections. The TDR softkeys operate in the same manner as those on the Pair 1 test result screen (see “Pair 1 Test”...
