2.4 Battery Care and Storage

It is important to observe these basic battery care procedures in order to avoid

possible damage to the battery and to maintain it’s performance.

� Warnings

• Failure to observe the following procedures and precautions can result in elec-

trolyte leaks, heat generation, bursting, fire, and serious personal injury.

• Battery electrolyte is a strong colorless alkaline solution, which is extremely

corrosive and will burn skin.

- If skin comes in contact with the electrolyte from the battery, thoroughly wash thearea immediately with clean water.

- If clothing comes in contact with the electrolyte from the battery, discard the

clothing.

- If any fluid from the battery comes in contact with eyes, immediately flush thor-

oughly with clean water and immediately consult a doctor. The electrolyte

can cause permanent loss of eyesight.• Keep the battery out of reach of children.

Cautions

• Never dispose the battery in a re.

• Never heat the battery.

• Never strike or drop the battery.

• Do not apply water, or other oxidizing agents to the battery. This will cause cor-

rosion and heat generation. If the battery becomes rusted, the gas release vent

may no longer operate and cause the battery to burst.

• Do not charge the battery using an AC adapter or charger not specied by Sunrise

Telecom. Charge the battery only with the Sunrise Telecom charger/AC adapter

that came with your test set.

- If the battery is not fully charged after the battery charger’s predeterminedcharging period has elapsed, stop the charging process. Prolonged chargingmay cause leakage of battery fluid, heat generation, and or bursting.

- Charge the battery within a temperature range of 0°C (+32°F) to +40°C

(+104°F).

• Do not use the battery if it leaks uid or changes shape; otherwise it may cause

heat generation, bursting, and fire.• Do not short circuit the battery by connecting the positive (+) and negative (-)

terminals together with electrically conductive materials, such as lead wires,

etc.

• Do not connect the battery directly to a power source or the cigarette lighter socket

in a car. Use a specified cigarette lighter charger from Sunrise Telecom.

23

ACM-Lite


24/68

• Never disassemble the battery. Doing so may cause an internal or external short

circuit, or result in exposed material of battery reacting chemically with the air.

It may also cause heat generation, bursting, and or fire.

• Never modify or reconstruct the battery pack. Protective devices are built into

the battery pack. If damaged, excessive current flow may cause loss of control

during charging or discharging of the battery, which can result in leakage of

battery fluid, heat generation, bursting, and or fire.

• The gas release vent, which releases internal gas is located in the positive (+)

terminal of the battery. For this reason, never deform, cover, or obstruct this

vent.

• When the battery operating time becomes much shorter than its initial operating

time even after recharged, the battery has reached its end of life and should be

replaced with a new one.

Extended Battery Storage

• Fully charge the battery before storing.

• Remove the battery from the test set. Follow the procedure in Section10.

• Do not store battery in high temperatures, such as direct sunlight, in cars during

hot weather, or near any other heat source. This will impair the performance and

shorten the operating life of the battery, and may cause battery leakage.

- For maximum battery life, store the battery between -20°C (-4°F) and +30°C(+86°F).

• During storage the battery will need to be regularly recharged. The interval ranges

from approximately 30 to 90 days at temperatures between -20°C (-4°F) and

+30°C (+86°F). In general the higher the storage temperature the shorter the

recharge cycle.

- To recharge, install the battery into the test set and use the supplied Sunrise

battery charger to recharge the battery.

- Charge the battery within a temperature range of 0°C (+32°F) to +40°C(+104°F).

• After long-term storage, there is a possibility that the battery will not fully recharge.

To fully charge it, charge and discharge the battery for a few times. Use the test

set to discharge the battery.

3 TDR Menu & Applications

A Time Domain Reflectometer (TDR) operates by sending a pulse of energy down

the cable. It then measures any reflections that return to the MTT. These reflections

are caused by faults that cause impedance changes in the cable. For example, a

load coil looks like a large increase in impedance (the high frequency pulses can-not pass through) and can easily be detected by a TDR. Any major change in the

twisted pair’s plastic insulation or the cable fill’s material (like water in the cable)

causes a reflection.

A TDR plays an integral role in testing DSL circuits. It can:

• Locate bridge taps, indicating the presence of a bridge tap, the exact location,

and the length of the lateral.

• Locate load coils, showing the presence and exact location of load coils.

• Detect any other circuit faults like an open or shorted cable.

ACM-Lite


28/68

TYPE: Specify the cable insulation type, which is a factor in determining VP.

Options: PE AIR (F1), GEL (F2), PVC (more, F1), PAPER (more, F2)

• PE AIR: Polyethylene/air filled, insulated cable

• GEL: Polyethylene/jelly filled, insulated cable

• PVC: Polyvinyl insulated cable

• PAPER: Paper/pulp insulated cable

GAUGE: Specify the wire gauge.

Options: Eng: F1= 24/19/28, F2= 26/22/20

Metric: F1= .4/.6/.3, F2= .5/.9/.8

The wire gauge is a factor in determining VP. An incorrect setting may result in

less accuracy. If you are testing a cable span with mixed gauge values, select the

highest gauge value. Use the more (F4) key to see the available setting.

• The UNITS setting determines if the gauge is expressed in AWG (English) or

mm (Metric).

• In North America, thickness is expressed in AWG (American Wire Gauge). A

value of 24 AWG refers to wire that is 1/24 inch diameter.

• Outside North America, thickness is expressed in millimeters. I.e., 0.4 mm is

comparable to 26 AWG; 0.5mm is comparable to 24 AWG.

VP: Set the Velocity of Propagation

Options: from .40 to .99

• Use the (F1) and (F2) keys to change the Velocity of Propagation. The more

(F4) key sets the increment/decrement factor at +/- .01 or +/-.1

• This setting is important for accurate results; if you are unfamiliar with Vp set-

tings, please read the following.

Velocity of Propagation

Propagation Velocity (Vp) indicates the speed that the signal travels down the

cable. It is a ratio of the speed in cable to the speed of light; a value of .65 means

the signal travels down that cable at 65% the speed of light.

Using an accurate Vp is crucial for TDR measurements. This calibrates the MTT

for the particular cable type. Find the Vp in the Cable’s specification sheet or from

the manufacturer. If you cannot find it, take a representative cable of a known

length and measure it with the MTT’s TDR. Change the VP setting until the test

set provides an accurate distance reading.

AVG: Determine the number of times the MTT Lite sends the pulse. Options: 1-5

If this value is set for greater than one, the tester displays an average of all at-tempts. The recommended setting for AVG is 1. Use the +1 (F1) and -1 (F2) keys

to set the value.

Press START (F3) to begin the TDR Measurement.

the cursor at the beginning of the reflection, you have identified the fault loca-

tion.

• If you need to adjust the display vertically, press +OFFSET (more, F1) or -OFF-

SET (more, F2).

Adjusting the ZoomYou can use ZOOM_IN (F1) and ZOOM_OT (F2) to scan the entire cable span for

faults or focus on a particular fault or cable segment. ZOOM_OT shows more of the

cable span, while ZOOM_IN focuses on shorter portions. Note the ‘H’ (horizontal)

value at bottom right displays the Zoom factor. It can range from 1-320 (1 being the

closest range and 320 being the farthest out). Zooming out to the maximum value

(H= 320) enables you to view the entire span length so you may better locate cable

faults. Zooming in allows you to interpret potential faults.

Upon entering the TDR screen, press ZOOM_OT (F2) until you have zoomedout all the way (H=320) to see the entire cable span.

2. While the test set is searching for a fault, it will display “SEARCHING”.

3. When it has found a fault, it will be displayed on the screen. “FOUND” appears

at the top right, as shown in Figure 17.

4. The test set automatically places the cursor near the fault. The DISTANCE read-

ing at the top left provides the cursor’s location. Use the left and right arrow keys

to adjust the position.

5. If the test set does not find any faults, it will show ‘NONE’ in the top right. You

still may want to zoom out and manually search for any faults.

3.3.1 Finding Multiple Faults

You can see past a bridge tap, cable splice, wet cable, or other impairments with a

TDR. However, a TDR cannot show beyond an open, load coil, or short. For example,

if a load coil is detected, it must be removed before you can continue looking formore faults with the TDR. Refer to the following scenario for locating multiple faults

with your TDR.

36/68

TDR Hints

• Adjust the zoom value to your approximate cable length; check the right-side

distance in brackets. Zooming out as much as possible (H=320) allows you to

view the entire cable length, but it may make locating smaller or near faults more

difficult to interpret.

• The MTT has a xed pulse width for the span that is displayed. At times, whenviewing far distant cable, you may want to increase the gain. This will make

distant faults more visible. Press the up arrow key once to increase Gain. Note

the GAIN value at the lower right (V).

• To nd the exact distance between two points (i.e the start of a bridge tap and

the end of that lateral), place the Cursor at one end, and the Marker at the other.

The MARKER reading below the graph provides the difference between the

two.

3.3.2 Sample Trouble Indications on the TDR

The polarity of the reflection reveals the type of fault:

• Upwards spike: indicates open or load coil.

• Downwards spike: indicates short.

• Downwards followed by upwards: indicates bridge tap.

Load Coil/Open

Figure 22 shows a load coil or open at 3335 feet. Load coils are inductors (typically

88 mH) placed in long POTS circuits (longer than 18,000 ft). Since high frequency

signals do not pass through load coils, ADSL circuits cannot tolerate load coils. All

load coils must be removed for ADSL transmission.

One key to identifying load coils is location. Load coils are placed approximately

3000 ft from the Central Office. They are then placed every 6000 feet. Another key is

shape: the waveform is typically more rounded than that of an open and the baseline

after the reflection is lower than before the reflection.

�

Figure 22 Typical Load Coil/Open

Bridge Tap

Figure 23 shows a typical bridge tap. The bridge tap begins at 835 feet and extends

for 249 feet (DISTANCE provides the beginning; MARKER provides length). The

bridge tap begins with the steep downward slope; the lateral continues until the

sharp upward slope, or bump, which represents the open at the end.

Figure 23 Typical Bridge Tap

Here are some guidelines for bridge taps in DSL circuits:• The sum of all bridge taps must be less than 2500 ft (Bellcore TA-NWT-00120,

for HDSL circuits).

• One individual bridge tap may be no longer than 2000 ft (Bellcore TA-NWT-00120,

for HDSL circuits).

After finding and removing a lateral, retest the cable for any other laterals or faults

that may have been missed.
