TS®44DLX Deluxe Test Set

Introduction

The TS44DLX Deluxe Test Set is an analog test
telephone used by installers, repair technicians and
other authorized personnel to test copper wire voice
subscriber lines. In addition to providing standard off­hook operations, such as dialing and voice
communications, the TS44DLX Deluxe model has an
on-hook Monitor Mode that lets the operator listen to
the line without disturbing any voice or data signals
present. The test set has a speaker for hands-free
listening. The test set also has a speakerphone that
allows two way conversations while freeing up the
operator’s hands for other tasks.

In today’s telecommunications environment, a large
number of subscriber lines carry data services. The data
services are in the same distribution facilities as voice
services. It is not always easy to tell the difference
between data and voice services. The TS44DLX Deluxe
Test Set uses unique, patented circuitry that prevents
disruption of digital data services if the test set is
unintentionally connected to a data line.

Users Guide

When the LO BATT LED begins flashing, the battery,
has anywhere from several hours to several days of life
remaining depending on how often the speaker is
used.

See “Replacing the Battery” on page 15 for instructions
on changing the battery.

If the test set stops working, remove the 9 V battery,
wait at least 40 seconds, then replace the battery. This
resets the test set. Use the same battery if you know it
is good or use a new battery if you are not sure. If it still
doesn’t work, contact Fluke Networks Technical
Support.

Speaker and Speakerphone Microphone

See Figure 1.

The speaker and speakerphone microphone are
located on the keypad side of the test set. The speaker
draws more current than any other circuit in the test
set. The battery lasts longer if the speaker is used in
moderation.

Audio Controls

See Figure 2.

The three audio control keys are located on the inside
handle of the test set between the handset receiver
and the handset microphone. These controls let the
operator switch between the handset and speaker­phone, mute the active microphone, and control the
volume of the received audio signal. Table 1 describes
the audio control keys.

WWarning

Never hold the speaker against your ear
when it is on, or when turning it on or off.
Sounds emitted by the speaker can be loud
enough to damage your hearing.

Keypad Controls and Indicators

See Figure 3.

The keypad has 19 keys that are recessed into the
housing. The recessed bezel protects the keypad and
helps prevent accidental key presses. Table 2 describes
the keys and other indicators on the test set.

Table 1. Test Set Audio Control Keys

Key Description (refer to Figure 2)

MUTE The MUTE key functions only when the test set is off-hook. When the test set is off-hook and being

used as a handset, pressing the MUTE key shuts off the handset’s microphone. This is useful in noisy
environments such as near heavy traffic. With the mute on, ambient noise is not picked up by the
test set’s microphone and therefore not transmitted to the speaker. When the mute is on, it is easier
to hear the person at the other end of the line and easier to hear static or noise on the line. Pressing
the MUTE key again turns the microphone on.

When the test set is off-hook and is in Speakerphone mode, pressing the MUTE key will shut off the
speakerphone’s microphone and will put the test set into a Receive-Only Loud Speaker mode. This is
a better mode for troubleshooting than Speakerphone mode. Pressing the MUTE key again will turn
the speakerphone microphone on.

The test set may be configured to operate exclusively in Receive Only Loud Speaker mode. When in
this mode, the MUTE key has no effect on test set operation while in loudspeaker mode. See
“Configuring Your Test Set” on page 12.

When the mute is on, the MUTE LED flashes.

VOL
(Volume)

SPKR
(Speaker)

Pressing the VOL key switches the active receiver’s sound level between normal and high volume.
This occurs in Monitor mode and Talk mode. The state of the VOL key is preserved when the active
receiver is changed. For example, with the handset receiver volume set to high, if you switch to the
speaker, it will also be set to high volume. The VOL key affects only the volume of received signals. It
does not affect the volume of transmitted signals.

The SPKR key turns the test set’s speaker on and off. It functions in both Talk and Monitor modes.
In Monitor mode, if the test set is being used as a handset, pressing the SPKR key turns on the

speaker. This lets you monitor a line while working at a distance from the test set.
If the test set is off-hook and is being used as a handset, pressing the SPKR key turns on the

Speakerphone. The handset microphone and receiver are shut off and the speakerphone
microphone and speaker are enabled. This mode is intended for two-way, hands-free conversation.

You may also configure the test set to operate exclusively in Receive Only Loud Speaker mode (see
“Configuring Your Test Set” on page 12). For test sets configured as Receive Only Loud Speaker, if
the test set is off-hook and is being used as a handset, pressing the SPKR key turns on the Receive
Only Loud Speaker. This mode is intended for listening to the line, hands free.

TONE/PULSE

key

The TONE/PULSE key switches the test set between tone and pulse dialing. The TONE/PULSE key is
active only when the test set is off-hook. Any time the test set goes off-hook, it is automatically set
to tone dialing. Once off-hook, pressing the TONE/PULSE key changes the dialing mode to pulse
dialing. Pressing the key again will switch back to tone dialing.

TEST key The TEST key performs three different tests. Two of the tests are performed when the test set is

on-hook and one of the tests is performed when the test set is off-hook. The test results are
meaningful only if the unit’s test leads are connected to tip and ring of a subscriber line.

When the test set is on-hook, pressing the TEST key causes two tests to be executed. Both tests are
performed simultaneously. When the TEST key is pressed, the test set searches for data on the
telephone line. If the test set detects data, the data-detect alarm sounds for about 5 seconds
letting you know there is data on the line. If there is no data, the test set sounds a brief
confirmation tone indicating the test was run and no data was detected. Simultaneously, the test
set measures the dc voltage across Tip and Ring and displays, by LED, whether the voltage is high,
low or normal. The indications provided by this test are described under “HI/LO Voltage LEDs”.

The purpose of the test is to indicate the approximate dc voltage on the line. For example, the
user runs the test, expecting a normal battery feed of -48 Vdc on a line; instead, the amber LED
flashes indicating the dc voltage is lower than a normal CO battery. This indicates the test set may
be connected to the wrong pair, or there may be a problem with the line.

The POL LEDs double as low loop current indicators. When off-hook and the TEST key is pressed, if
the current reading is below 23 mA, the LED corresponding to the line polarity will flash for 5
seconds. If the loop current is normal, the LED will light solid. Low loop current may indicate a
problem on the line.

Notes

The TS44DLX Deluxe Test Set is not polarity sensitive, and will function in either polarity.
The POL LEDs will not light if the test set is on-hook or when the speaker is on.

When the test set is off-hook, one of the two POL LEDs light to indicate the dc polarity of the line.
The green POL LED lights if the red test lead is connected to the Ring (negative) side of the line
and the black test lead is connected to the Tip (positive) side of the line. The red POL LED lights if
the test leads are reversed; that is, the red test lead is connected to the Tip (positive) side and the
black test lead is connected to the Ring (negative) side.

The POL LEDs double as low loop current indicators. When off-hook and the TEST key is pressed, if
the current reading is below 23 mA, the LED corresponding to the line polarity flashes for 5
seconds. If the loop current is normal, the LED lights solid. Low loop current may indicate a
problem on the line.

The electronic ringer is enabled while the test set is on-hook.

When the test set is on-hook and the TEST key is pressed, the test set measures the dc voltage
across Tip and Ring and indicates the voltage level as follows:

Voltage Range
0 V to 2 V LO Vdc LED lights for 5 seconds
2 V to 42 V LO Vdc LED blinks for 5 seconds
42 V to 53 V (Normal CO battery voltage) Both the LO Vdc and HI Vdc LEDs flash once
53 V to 140 V HI Vdc LED blinks for 5 seconds
Above 140 V HI Vdc LED lights for 5 seconds
For voltages that cause either LED to light solidly for 5 seconds, the test set will not allow off-hook

operation.
If the test set is placed in Talk mode on a loop with more than 140 Vdc, the test set locks out and

the HI Vdc LED remains lit until the test set is placed in Monitor mode or the voltage drops below
140 V.

Operation

Operation

The test set has two basic modes of operation: Talk
mode and Monitor mode. Talk mode is used for off­hook operations (such as dialing verification, automatic
number identification, and audio quality verification).
Monitor mode is for audio monitoring of the Tip and
Ring pair while on-hook. In Monitor mode, the test set
has a high input impedance, which allows monitoring
of the line without disrupting conversations or data, if
present.

WCaution

When testing circuits that are close to a
battery source, clipping onto a line may case
loud pops in the receiver. Holding the
receiver tightly against your ear may cause
acoustic shock. The test set is designed to
rest comfortably on the shoulder with some
space between the receiver and the ear. It
should be used in this position when
working close to a battery source.

Shorting the Tip and Ring leads together
while connected to a data line will disrupt
data on the line.

In the Monitor mode, the test set is typically used for
one or more of the following procedures:

•

Verification that a line is idle when looking for a
line to borrow

•

Listening for noise on the line

•

Hunting for tracer tones

•

Testing for high frequency data on the line by
using the TEST key.

•

Testing for dc voltage on the line by using the TEST
key.

Operating the Test Set in Talk Mode

In Talk mode, the test set performs a brief test for high­speed data and talk battery on the line. If high-speed
data is detected, the test set generates an audio alarm
and remain on-hooks. If high-speed data is not
detected and talk battery is present, the test set goes
off-hook. When off-hook, the test set operates like a
standard telephone and is typically used to verify the
proper operation of a voice telephone line or to
establish temporary communications on a “borrowed
pair”.

Originating a Call

Talk/Monitor Switch

See Figure 1.

The Talk/Monitor switch is a rocker switch located on
the side of the test set. The T position puts the test set
into Talk mode. The M position puts the test set into
Monitor mode.

Operating the Test Set in Monitor Mode

In Monitor mode, the test set is always on-hook. The
test set draws no direct current from the line and it
transmits no signals to the line. In this mode, the test
set has a high ac input impedance, which allows
listening for audio signals without disrupting
conversations or data signaling that may be present.
Either the handset receiver or the speaker can be used
to monitor a line.

1

Set the Talk/Monitor switch to M.

2

Clip the test set to Tip and Ring of a subscriber
loop.

3

Monitor (listen to) the line to verify it is idle.

4

If not idle, disconnect the test set from the line.

5

If the line is idle, set the Talk/Monitor switch to T.
The test set automatically tests for high-speed data
and talk battery on the line.

6

If data is detected, the test set will not go off-hook
(will lockout) and will alarm, indicating the
presence of data. Try another line.

high-speed data on the line.

2

If there is no data and talk battery is present, the
test set goes off-hook and draws dial tone.

Note

The TS44DLX Deluxe will not go off-hook if the
line voltage exceeds 140 Vdc.

3

If data is detected, the test set will lockout and
alarm, indicating data is present.

4

To go off-hook with data present, press the
Override key sequence (see “Data Lockout
Override Operation” on page 11).

Data Lockout Operation

With the increase in high capacity data lines in the
distribution system comes the greater risk of disrupting
data services when working on analog lines. The test
set is designed to be used by Outside Plant and Central
Office technicians to perform their normal duties while
greatly reducing the possibility of accidentally
disrupting data service.

Accidentally going off-hook on a data line while
searching for talk battery or dial tone on an unmarked
terminal block or cable splice could bring down a high­capacity data lines. To prevent this, the test set provides
an automatic data lockout function. When the test set,
with its Talk/Monitor switch in the T position, is
connected to a Tip and Ring pair, it automatically tests
the line for high-speed data (data signals that are
above the human audio range) before going off-hook.
If data is detected, the test set locks out, preventing
itself from going off-hook, and it provides a continuous
audio alarm indicating it has detected data.

When the test set is locked out, it remains on-hook, it
does not draw direct current from the line, and it
presents a high ac impedance to the line to prevent
disruption of data. The test set can detect and protect
the following data services: ISDN BRI, ISDN PRI, 56k
DDS, SW56, T1 and E1, HDSL, IDSL, SDSL, ADSL DMT,
ADSL CAP, and ADSL LITE.

Data Safe Practices

Ground Start

Ground start lines are typically found on PBX
installations. To activate an idle ground start telephone
line, do the following:

1

Set the Talk/Monitor switch to M, and connect the
test leads to Tip and Ring of the ground start line.
With a third wire, temporarily short the Tip side of
the line to earth ground. A wire with an alligator
clip at each end is often used for this. Do not allow
clips to short network connections.

2

With the short to earth ground in place, set the
Talk/Monitor switch to T. When dial tone is
received, remove the third wire from earth. The
circuit is now ready for dialing.

10

Always monitor the line for an audible signal before
attempting to go off-hook to draw dial tone. The data
detect circuitry on the test set is designed to detect
data signals above the human audio range. To detect
data signals within the human audio range, such as
produced by voiceband modems and subrate DDS
transceivers, you must listen to the line using the test
set’s audio monitoring capability. If you hear the hiss of
a voice band modem or low frequency data transceiver,
do not move the Talk/Monitor switch to T. If you do
switch to T, the test set will not lockout because it does
not detect low frequency data. It will go off hook and
will interfere with the voice band modem or data
transceiver. To avoid this, try another line or wait until
the line is idle.

Operation

Data detection is a two part process. The first part
requires listening to the line for audible data traffic in
Monitor mode as described above. If the line is quiet,
then the second part is to use the test set’s data detect
capability to determine if there is data above the
human audio range on the line. This can be done in
one of two ways.

•

You can test for high-speed data with the test set
still in Monitor mode by pressing the TEST key. If
there is high-speed data on the pair, the test set
generates an alarm for about 5 seconds. If there is
no data on the line, the test set generates a brief
confirmation tone. If the warning alarm is not
sounded, then switch the test set to Talk mode,
and it will go off-hook.

•

You can test for data by switching the Talk/
Monitor switch to T. The test set automatically
performs a brief test for high-speed data. If there
is data on the line, the test set locks out, (remains
on-hook) and generates a data warning alarm. If
there is no data on the line, the test set goes off­hook.

When going from pair to pair searching for tracer tone
or dial tone it is best to connect the test set to Tip and
Ring of the pairs. Avoid the practice, either in Talk or
Monitor mode, of clipping one lead of the test set to
ground, and using the other lead to search for tracer
tone or dial tone on a block. This may create an
electrical imbalance on a data line that will disrupt
service. Once you find the voice line you are searching
for then it is OK to test Tip to ground or Ring to ground
on that line.

Be careful not to short the test leads together when
connecting to a data line (or any line for that matter),
as this could bring down the service.

It is best to put the test set in Monitor mode when
troubleshooting a line, searching for capacitance kicks,
RF signals, craft provided tones, etc.

Data Lockout Override Operation

Normally, when the test set detects data, it means the
operator has accidentally connected to a high-speed
data line and should immediately disconnect from the
line to avoid disrupting the data service. But in some
cases the operator must go off-hook on a specific line
even though the test set indicates that the line is a data
line.

The following are scenarios where the operator may
wish to override a data lockout:

•

When there is false data detection due to RF
pickup on a line that is near an AM radio
broadcast antenna. The RF induced in the line may
appear to be data.

•

When performing a ground start, the test set may
generate the data alarm when the Talk/Monitor
switch is in the T position. This is because ground
start lines are unbalanced before startup and thus
are prone to picking up a lot of noise which may
appear to be data to the test set. If this occurs, use
the override function to go off-hook on a ground
start line.

Telephone lines near AM radio broadcast facilities, pick
up the RF signals from the broadcast antennas.
Normally this isn’t a problem for the test set. If the line
is well balanced, the test set will not see the RF signal
because it is a common mode (longitudinal) signal. But
if the line is unbalanced, part of the RF signal will be
converted to a differential (metallic) signal. If the signal
amplitude is high enough, it may be detected as high­speed data by the test set. If you know for sure you are
on such a line, use the unit’s override capability to go
off-hook.

The data lockout override can be activated only when
the Talk/Monitor switch is in the T position. To activate
the override, press the STORE/PROG key then the TEST
key. If dc voltage is present, the test set goes off-hook.
To go back on-hook, unclip the test set’s test leads from
the line or put the test set into Monitor mode. The
override key sequence must be executed each time you
want to take a locked-out test set off-hook.

TS44DLX Deluxe Test Set

Users Guide

High Voltage Lockout Operation

The TS44DLX Deluxe is designed for use by Outside
Plant and Central Office technicians in environments
where analog voice lines co-exist with lines that carry
high dc voltage.

Accidentally going off-hook on a line carrying a high dc
voltage can damage the power supply feeding the line.
To prevent this, the TS44DLX Deluxe provides an
automatic high-voltage lockout function. When a
TS44DLX Deluxe is connected to a Tip and Ring pair
with its Talk/Monitor switch in the T position, it
measures the voltage on the line before going off­hook. If the measured voltage exceeds 140 Vdc, the test
set locks out, preventing itself from going off-hook.

The high-voltage lockout condition is indicated by a
solidly lit HI Vdc LED. In the event of a high voltage
lockout, the Talk/Monitor switch should be set back to
the M position, and the test set leads should be
carefully removed from the line.

WCaution

Do not short the test leads to each other
while it is connected to a line carrying high
voltage.

In tone dialing mode, the dialing keys that may be
stored in LNR memory include 1,2,3,4,5,6,7,8,9,0,*,#
and PAUSE. If the star (

Program Speed Dialing Numbers

While in Monitor mode, the test set allows the storage
of ten speed dialing numbers in ten memory locations
(0 through 9). Each location stores up to 23 digits. If an
attempt is made to store more than 23 digits, only the
first 23 are stored. The PAUSE key is accepted as a
dialing digit when storing numbers.

Configuring Your Test Set

Last Number Redial

In the Tone or Pulse dialing mode, the last number
dialed can be automatically redialed by pressing the
LNR key after going on-hook and then back off-hook.
To redial a number, the LNR key should be the first key
pressed after going back off-hook.

If, after going off-hook, any dialing key is pressed, the
LNR memory is cleared and the value of the pressed
key is the first number stored in the cleared memory.

The PAUSE key is considered a dialing key. If pressed, a
pause is stored in the redial memory, taking up one of
the 23 digit slots.

Hook Flash Duration

When the test set is off-hook, pressing the FLASH key
causes a timed interruption of the loop current to
occur. Some PBX setups or telephone office switches
may use this signal to put a call on hold or to activate
some special function. One flash is generated for each
press of the key.

To change the flash duration value:

1

Set the Talk/Monitor switch to M.

2

Press the STORE/PROG key.

3

Press the FLASH key.

4

Press a number key to select a hook flash time.
Invalid entries are ignored. The test set gives a
confirmation tone when the entry is accepted.

Note

Each time the PAUSE key is pressed, it counts as
one dialing digit.

In some situations it may be necessary to put a pause
between digits of a stored number, as when accessing a
trunk through a PBX that requires a 9 to get an outside
line. You can do this by pressing the PAU SE key at the
point where the pause is required. For example, to
store the number 9-555-1234, with a pause between
the 9 and 5, enter 9[PAUSE]5551234. When the
number is dialed out, there will be a pause between
the 9 and 5. The duration of a pause is user
programmable (see “Pause Duration” on page 14). You
can insert a longer pause by pressing PAUSE more than
once.

Pause Duration

The PBX Pause feature lets you insert a delay into
speed dialing numbers. This is required when dialing
out through a system that provides a second dial tone
(such as PBX). Different PBX devices may require
different pause durations to allow enough time for the
second dial tone to be returned. The pause duration
can be programmed.

To change the PBX Pause duration:

1

Set the Talk/Monitor switch to M.

2

Press the STORE/PROG key.

3

Speaker Timeout

The speaker draws more current from the battery than
any other circuit on the test set. The battery drains
quickly when the speaker is left on continuously. To
extend battery life, the test set has a timeout function
that automatically turns off the speaker when the test
set is on-hook. A timer starts whenever the test set is
put on-hook. When the test set is off-hook, the timer
will not start.

If the test set is used as a handset in Monitor mode and
if the test set’s receiver has been set to high volume,
the battery is drained very quickly. To avoid this, the
tester has a timeout function for the high volume state
when in Monitor mode. After the timeout, the test set
reverts to low volume.

The speaker timeout duration is programmable while
on-hook and 240 minutes (4 hours) while off-hook. The
off-hook timeout cannot be changed. Remember, the
longer the selected timeout duration the shorter the
battery life.

To change the speaker timeout duration:

1

Set the Talk/Monitor switch to M.

2

Press the STORE/PROG key.

Exclusive Receive Only Loud Speaker

In some situations (such as when searching for dial
tone), you may prefer to have the test set’s speaker
remain in Receive Only mode (muted) while
transitioning in and out of Talk mode. To do this, you
may configure the test set to operate with the speaker
exclusively in a receive only mode.

To enable/disable Exclusive Receive Only Loud Speaker
