Introduction

Using This Guide

This 990DSL CopperPro Loop Tester Users Guide shows you how to operate the 990DSL CopperPro Loop Tester (hereafter referred to as the “CopperPro” or “tester”). It provides instructions for configuring the CopperPro and using it to precisely locate common faults on a loop and to verify the ability of a copper loop to transport various classes of high-speed data services.

This guide is intended for users who want to start using the CopperPro immediately with minimal instruction. It describes the main features of the tester and explains how to set up, operate, and care for it. For your protection, it is important that you observe all warnings and important safety information in this guide and on the tester itself.

Introduction

The 990DSL CopperPro Loop Tester is a portable, battery-operated handheld tester that is used for cable installation testing, fault location, and digital service qualification of outside plant (OSP) paired copper cables.

As a cable installation test tool, you can use the CopperPro with an external multiple-pair access module in a PC-controlled mode to perform automated, single-ended conformance testing of a newly installed cable according to operating company guidelines. If more rigorous conformance testing is required, you can use a second CopperPro with a multiple-pair access module at the far end of the cable to perform precision-terminated transmission testing.

As a fault location test tool, you can use the CopperPro to precisely locate common physical cable faults, including shorts, grounds, crosses, opens, splits, and pair imbalances that are caused by poor splice joints. The tester can also be used to expose corroded metallic faults on unused pairs. This type of problem, which is virtually undetectable by conventional meters, can eventually cause a pair to be noisy after it is cut into service.

The CopperPro is also a useful tool for helping you find the root cause of transmission problems, such as excessive loss and noise. Additionally, it can detect and identify loop treatment and fault-sectionalizing devices that are commonly installed on lines, such as range extenders (REGs), Network Interface Devices (NIDs), and Maintenance Termination Units (MTUs).

As a digital service qualification test tool, you can use the CopperPro to verify that a cable pair is suitable for voice frequency POTS services (such as Caller ID and analog modem data) and for special services, such as DDS, ISDN, T1, E1, HDSL, HDSL2, HDSL4 and ADSL. The CopperPro uses wideband loss, Gaussian noise, impulse noise, and crosstalk measurements, as well as load coil detection and location capability to qualify copper pairs for these highspeed services.

Page 31

Controls and Connections

The Battery

In the upper right corner of the screen, the tester displays two icons, which indicate the following:

• External power source in use (either AC power or not AC power)

• Battery capacity.

Responding to Low Battery Warnings

When the NiMH battery pack has about 30 minutes of operating time remaining, the tester issues a tone and displays a low-battery warning on the LCD. This warning overlays the currently displayed screen.

Note

To remove the warning, press L.

If the low battery warning appears while you are operating the tester, it is advisable to connect the CopperPro to an external power source within the next several minutes to guarantee that the currently displayed test data is not lost due to a power failure. If you continue to operate the CopperPro without an external power source, the tester issues a final distinctive audible tone and powers itself off.

Charging the Battery

To charge the battery, either connect the CopperPro to AC power (see “Connecting to AC Power”) or connect it to an automobile battery (see “Connecting to an Automobile Battery”).

2-11

Page 32

990DSL

Users Guide

During operation from either external power source, the battery receives a “trickle” charge that allows you to operate the tester for extended periods of time without discharging the internal battery pack. When the CopperPro is connected to an external power source but turned off, the battery automatically undergoes a fast-charging cycle.

A full charging cycle can take between two to three hours to complete. The charging status LED on the side connector panel indicates the state of the battery charge as one of the following:

• Flashing red: indicates that the battery is being prepared for fast charging,

and is in the “pre-charge” mode. This state lasts for several minutes before the battery enters fast charging mode. This state will be extended for extremely low voltage, low temperature, or high temperature battery conditions, with the fast charge mode beginning when the battery has reached the proper voltage and temperature range.

• Steady red: indicates that the battery is in fast-charging mode. In this

mode, it can take up to three hours for a completely discharged battery pack to charge.

• Steady green: indicates that the battery is in the final stages of charging.

The first stage, which typically lasts for about 30 minutes, occurs after the fast-charging mode is the “top off” state. The final stage is the “trickle charge” state. In this state, the battery is fully charged. The CopperPro can be left in the trickle charge state for an indefinite period of time, without harm.

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. The POTS Auto-Test is comprised of a sequence of individual parametric tests that run automatically. Results from this test can give you a quick overall assessment of the performance characteristics of either a spare or working POTS pair.

The chapter then describes the individual tests in the POTS toolbox. This toolbox contains a group of specialized tests that provide detailed information to help you diagnose specific problems in a cable. In the POTS toolbox, you will find two groups of tests: copper media (DC) tests and transmission (AC) tests. The copper media tests are designed to identify and locate physical voltage, resistance, and capacitance faults, and test for continuity in a cable. The transmission tests provide accurate measurements of signal loss, metallic noise, power influence, and longitudinal balance to help you uncover root problems affecting signal transmission.

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 if you supply the cable gauge and temperature.

To convert the fault resistance values to distances, complete the following:

1. On the Shorts & Grounds result screen, press D(

Ohms-to-Distance).

2. If the cable gauge or temperature is different from that specified in the

setup for the test, do the following:

• If the pair consists of only one gauge, press D(

Setups), and select

the proper gauge and temperature. Then press M.

• If the pair consists of more than one gauge, press C(

Gauge

). Then enter each section length and gauge (see “Entering

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).

You do not need to provide the”D” Factor (or TG /TR Capacitance Ratio) or have to ground a percentage of spares in the cable to get an accurate distance reading, as you do with conventional 2-terminal meters. The CopperPro actually measures the Capacitance Ratio of the pair during the Opens Test.

The Opens Test performs a measurement of the capacitive length of the pair, as well as the capacitive balance between the Tip and Ring conductors.

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. Alternatively, if the length of a good pair is known by another more accurate means, you can enter that length and store the data as a Custom Cable Type. This is called an Adjusted Opens measurement.

Figure 4-8 shows the results from a balanced pair being used to create a Custom Cable Type for future usage on other pairs in the same cable

To run an Adjusted Opens test, do the following:

1. Run an Opens Test on a good, balanced pair in the cable.

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.

Note

The Splits test provides the approximate distance to a split. To precisely locate a split, it is recommended that you run a TDR test (see Chapter 6 “TDR Testing and Fault Location” for details).

Figure 4-9 shows an Opens test results screen which reports a possible split.

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. Ratio, or a good pair having a non-standard 3T Cap. Ratio.

If the pair is a known good pair with a non-standard 3T Cap Ratio, you can create a Custom Cable Type with those characteristics by pressing A(

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” process. In this process, half of a resistance bridge is formed within the CopperPro, and the faulted pair (strapped at the far end, as prompted) forms the other half of the bridge. The internal bridge ratio is then changed until it precisely mirrors the ratio of the faulted leg to the good leg, and is then used to calculate resistance values to the fault and strap.

Setting Up an RFL Test

To set up an RFL test, follow the instructions under “Displaying a Setup Menu” in Chapter 3. Refer to Table 4-5 for RFL test setup parameters.

Leakage Stress Test

The Leakage Stress test is a continuous resistance test that uses a higher test voltage than normal, in order to “punch through” a potential metallic wire fault that has oxidized over time. During normal resistance testing, this type of fault will not typically show up on a spare pair. However, it will gradually appear under sustained application of C.O. battery voltage after being cut into service as a supposedly “good” pair.
