Chapter 4 POTS Testing and Fault Location Introduction This chapter shows you how to use the CopperPro to identify and locate common physical problems on OSP copper pairs, and how to qualify lines for POTS service. The chapter begins by showing you how to set up and run a POTS Auto-Test.
990DSL Users Guide POTS Auto-Test The POTS Auto-Test is a sequence of user-selectable single-ended parametric and transmission tests. The test can be run on either spare or working POTS pairs, with the appropriate selected tests automatically performed. It is an ideal tool to qualify POTS pairs, as well as providing an overview for fault analysis.
POTS Testing and Fault Location POTS Auto-Test Two groups of setup parameters are listed on this screen. The first group consists of the generic setup parameters, and the second group lists the tests that you can run under the POTS Auto-Test (refer to Table 4-1). If desired, supply a value for each generic setup parameter.

990DSL Users Guide Converting Fault Resistance Values to Distance Values Often the fault resistances displayed are “hard” shorts or grounds, meaning that the fault is at zero Ohms, and the resistance shown is only the conductor resistance itself to that fault. In these situations, the CopperPro can convert the resistances to distances...
POTS Testing and Fault Location The POTS Toolbox Opens Test The Opens test performs a true three-terminal test on a pair. To run the test, you need to choose the appropriate Cable Type (see Table 4-4).

Contin. Opens • Press C( ) if the pair is known to be a split pair (see “Splits Test” Splits later in this chapter). Test Equipment Depot - 800.517.8431 - 99 Washington Street Melrose, MA 02176 4-16 FAX 781.665.0780 - TestEquipmentDepot.com...
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.
990DSL Users Guide If the value is not correct: Cable Length • Press A( ), then enter a known good value for Adjust Cable Length (five digits maximum, no commas), and / or a value Cap. Reference if known to be non-standard.
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.
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.
POTS Testing and Fault Location The POTS Toolbox Verify that the pair is actually split with another pair, and then locate the second split pair with a tracing tone probe or other standard method. As prompted, connect the CopperPro Pair 1 and 2 test leads to the two split pairs exactly as shown in the connection diagram (Figure 4-10).
990DSL Users Guide Resistance Fault Location (RFL) Test The RFL test provides a highly accurate method of locating resistance faults (shorts, grounds, or crosses), including those that are too large for the TDR test to locate. It does this by using cable gauge and temperature values in a “nulling bridge”...

The tester then runs the first part of the test, performing a nulling bridge operation on the pair with the far end open.
POTS Testing and Fault Location The POTS Toolbox Load Coils Test The Load Coils test performs a frequency sweep of the pair (either spare or working POTS) to determine the number of load coils present, and the approximate distance to the first coil. Setting Up a Load Coils Test The Load Coils test requires that the predominant wire-gauge to the first load coil be entered in Setups, for the most accurate distance-to-first-load results.
The farthest load is represented on the extreme right side of the waveform, and will always have a relatively smaller dip and peak. Test Equipment Depot - 800.517.8431 - 99 Washington Street Melrose, MA 02176 FAX 781.665.0780 - TestEquipmentDepot.com 4-36...
POTS Testing and Fault Location The POTS Toolbox Note At times, small dips or peaks may be missed by the counter, yet be visually seen in the graph. Also, the presence of an abnormally high amount of metallic battery noise on working POTS lines may cause the counter to register a high false number of loads, but the actual number may be visually determined by looking at the graph.
990DSL Users Guide Loop Devices Test Results To run this test, follow the instructions under “Starting and Stopping a Test in the POTS Toolbox”, earlier in this chapter. Upon completion of the test, the CopperPro displays a result screen that lists each loop device and indicates whether or not it was detected on the test pair.

Chapter 6 TDR Testing and Fault Location Introduction This chapter describes the CopperPro’s TDR (Time Domain Reflectometer) test. The TDR testing function is a separately packaged and purchased software option that can often help you locate loop faults with greater precision than the parametric fault location tests that are described Chapter 4.
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.
990DSL Users Guide Reflections Reflections are caused by discontinuities in a cable’s characteristic impedance, such as gauge changes, splices, faults, the cable’s end, or series network elements. Positive (in-phase) reflections result from sudden increases in cable impedance, such as those due to opens, load coils, or resistive splices.
TDR Testing and Fault Location TDR Auto-Test Even though the individual TDR tests (described later in this chapter) can be performed on working pairs with voltage, the TDR Auto-Test should be run on non-working pairs only. This is because several of its integrated parametric tests (for example, Opens and Shorts &...

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.
