INTRODUCTION
The Teltone TLS-3B is a portable, two-line device that emulates the public telephone
network. The TLS-3B is a tool for demonstrating telephone instruments and other
telecommunications equipment, such as fax machines and modems. The TLS-3B’s
small size and light weight make it ideal for trade shows and other sales
presentations. It can also be used for testing telephone sets, key systems, and PBX
installations.
Like the public telephone network, but on a smaller scale, the TLS-3B can provide
dial tone, audible ring and busy signals to two telephones or other devices connected
to it. When a user picks up one phone (or other device) to dial up the second phone,
the TLS-3B sends ringing current to the second phone until it goes off-hook. The
TLS-3B then establishes a connection between the two phones. Either telephone can
then initiate a disconnect sequence by going on-hook.
Telephone Line Simulator
TLS-3B
Many of the TLS-3B’s features are programmable, including telephone numbers, offhook modes, signal delays, test tone frequencies, and line attenuation. The TLS-3B
also provides Caller Identification information to both lines, and lights a Visual
Message Waiting indicator.
In other words, the TLS-3B is a simple telephone network in a box. When a telephone
connection is not available, or when installing a temporary telephone line would be
costly, the TLS-3B provides all the signals and functions you will need to
demonstrate or test your telephones, modems, and other telecommunications
equipment.
TLS-3B CONNECTORS AND LIGHTS
The front panel of the TLS-3B has two telephone line jacks, with a green status
indicator light for each line, and a green Power indicator light. The power input
connector is on the rear panel. See Figure 1.

Status Lights
Figure 1. TLS Front and Rear Panels
When a telephone (or other device) connected to one of the Line connectors is off
hook, the corresponding Line indicator lights (see Table 1). The Line light dims (not
totally dark) when the TLS-3B decodes valid DTMF from the off-hook device. If the
off-hook device sends rotary dialing signals, the line indicator will flicker on and off
during dialing.
Table 1. LED Indicators
Indicator State Description
Line 1/Line 2
On Line is off-hook.
Flashing (fast on/off) Line is ringing.
Blinking (slow on/off) Programming mode: Line is
selected for programming.
Half brightness During dialing, indicates that a
valid DTMF digit is present.
Dim blinking between rings Caller ID is being sent to the
called phone number.
Single blink Setup 1 Power
Double blink Setup 2
When the TLS-3B sends a ringing signal to a telephone attached to one of the Line
connectors, the corresponding Line indicator flickers on and off rapidly.
The green Power indicator alternates between full and half brightness (blink) when
the TLS-3B is operating. A single blink indicates Setup 1. A double blink indicates
Setup 2. For information about programming different setups, see “Programming the
TLS-3B” on page 8.
40-400-00032, Rev. B

Page 9
If the Power indicator is dark, no power is connected to the TLS-3B. If it lights, but
does not flicker, the TLS-3B’s internal processor is not working properly.
Line Jacks
Two Line connectors (RJ11 modular telephone jacks) are located on the front panel.
These connectors mate with the plugs on standard modular telephone cords.
Power Connector
The power connector requires a 24-volt DC power source. A 120-VAC 24-volt DC
power pack is supplied with the TLS-3B. Do not use the TLS-3B with a power pack
that supplies a different voltage. Use only with a Class 2 power supply!
HOW TO INSTALL THE TLS-3B
The TLS-3B works with analog loop start telephone sets only. It will not work with
ground start, proprietary, or digital phone sets.
Follow these steps to install the TLS-3B:
TLS-3B User’s Manual
1. Plug the connector at the end of the power pack cable into the connector
on the rear panel of the TLS-3B.
2. Plug the power pack into a 120-volt AC wall outlet. The POWER
indicator will light.
3. Use a modular telephone cable to connect the telephones (or other devices
such as modems or fax machines) to the Line 1 and Line 2 connectors of
the TLS-3B.
4. Lift the handset of the telephone connected to Line 1. The Line 1 indicator
should light. Hang up and do the same thing for Line 2.
Warning: The TLS-3B generates a 100-volt ringing signal. Keep your hands
away from the plugs at the end of modular cables plugged into the TLS-3B
when the other line is off hook.
Caution: Do not try to connect the TLS-3B to the public telephone network.
Incoming ringing signals use voltages that can damage internal components in
the TLS-3B.

TLS-3B User’s Manual
Installing a Call Identifier
To use the TLS-3B’s Caller ID feature, you must use an external call identifier or a
telephone set with built-in Caller ID. In most cases, the call identifier goes between
the TLS-3B and the telephone set. You should follow the instructions supplied with
the call identifier. If the call identifier instructions tell you to plug a cable into a wall
outlet, connect it to the TLS-3B.
HOW TO OPERATE THE TLS-3B
The TLS-3B has one talk path between the two lines. When a telephone connected to
either line goes off-hook while the other is still on-hook, the off-hook telephone
receives dial tone. If a telephone is already off-hook, the second telephone will not
receive dial tone (silence).
The TLS-3B stores two separate configurations, called Setup 1 and Setup 2. This
enables two different users to store settings they use often (for example, the sales staff
might use the TLS-3B in one setup, and engineering the other). When the unit is in
Setup 1, the Power LED blinks once; when it is in Setup 2, it blinks twice. For
information about programming different setups, see “Programming the TLS-3B” on
page 8.
Each line has two programmable telephone numbers. For programming information,
see “Programming the TLS-3B” on page 8. To call the other telephone, lift the
handset and dial one of the numbers assigned to the telephone you want to call. The
TLS-3B recognizes both rotary (pulse) and tone dialing.
The default telephone numbers for the two lines are:
Line 1 = 101 and 201
Line 2 = 102 and 202
Calling Line 2
To call Line 2 (Primary):
• Dial 102.
One long ring (2 seconds on, 4 seconds off), repeated until answer.
To call Line 2 (Secondary):
• Dial 202.
Two short rings (programmable): 800 mS on, 400 mS off, 800 mS on, 4 seconds off
40-400-00032, Rev. B

Page 11
Calling Line 1
To call Line 1 (Primary):
• Dial 101.
One long ring (2 seconds on, 4 seconds off), repeated until answer.
To call Line 1 (Secondary):
• Dial 201.
Two short rings (programmable): 800 mS on, 400 mS off, 800 mS on, 4 seconds off
When the other telephone rings, lift the handset to answer. The two telephones are
now connected. To break the connection, hang up either telephone.
The Caller ID transmission sends the primary telephone number of the caller’s line.
Calling Party Supervision
TLS-3B User’s Manual
The U.S. telephone network typically uses Calling Party Supervision, meaning that
even though the called party hangs up, he may be reconnected to the calling party
when the phone is taken off-hook again. The calling party must hang up for the called
party to be fully disconnected before initiating a new call. The telephone network will
timeout and disconnect the call within 5-20 seconds, giving the called party dial tone
when he goes off-hook again.
The TLS-3B also provides Calling Party Answer Supervision. If the called party goes
on-hook and comes off-hook again before the forced disconnect or disconnect tone is
sent, the call will be reestablished. However, if the calling party goes on-hook and
then goes back off-hook again after the forced disconnect is sent, the call will not be
reestablished.
Forced Disconnect
Cutoff On Disconnect (COD) or Forced Disconnect, as it is also called, is a feature
provided by the TLS-3B. COD is a break in loop current that is sent to the off-hook
telephone when the other party goes on-hook (hangs up). The COD pulse duration is
programmable (default is 850 ms).
The COD delay (the time from on-hook until the COD pulse is sent) is also
programmable, but only for the calling party when the called party goes on-hook.
When the calling party goes on-hook, the COD delay is always 2 seconds before the
COD is issued to the called party.
For programming information, see “System Commands” on page 9.

Page 12
TLS-3B User’s Manual
Off-Hook Modes
The off-hook mode specifies what you hear when you lift the receiver on one of the
telephones connected to the TLS-3B. The three off-hook modes are Normal, which
provides dial tone; Ringdown, which causes the other telephone to ring; and Silence,
which connects the telephone to silence. The Normal mode is the default. For
programming information, see “Individual Line Commands” on page 11.
CALLER ID
The TLS-3B provides optional Caller ID (FSK) signaling on both lines. It supports
both Single Message Format (Date/Time/Number) and Multiple Message Format
(Date/Time/Number/Name). The Caller ID transmission is sent during the first long
silent interval after the first ringing cycle. A typical standard ringing period is
composed of a 2-second ringing cycle and a 4-second silent interval. Distinctive
ringing periods may be several short ringing cycles followed by at least a 3-second
silent interval. The TLS-3B is capable of many different types of ringing cycles and
silent periods (see “Programming the TLS-3B” on page 8), but a silence period of at
least 3 seconds is required in order to send a Caller ID message.
The display of the Caller ID information depends upon the type of equipment
connected to the TLS-3B, it may appear on the telephone itself, in the display of a
separate device, or on the video display of a personal computer.
Caller ID Date/Time
The TLS-3B issues a Date/Time value of 01/01 1:05 for the initial call after power is
applied. Subsequent calls will increment the time by 5 minutes. The Date/Time will
be reset back to the initial value of 01/01 1:05 if power is cycled on the TLS-3B.
Caller ID and Distinctive Ringing
Since there are circumstances such as privacy blockage, an out of area call, or a
transmission error, in which Caller ID is blocked, the TLS-3B can simulate these
events.
If you change the distinctive ringing cycles, remember that a 3-second silence is
required for the Caller ID information to be sent.
Compatibility with Caller ID Devices
Since there are a variety of Caller ID devices, the appearance of the information and
the amount displayed may differ slightly. For example, the format of the date and
time may be displayed differently.
40-400-00032, Rev. B
6
Page 13
Please note the following items when using Caller ID equipment:
• Some Caller ID devices cannot display the calling name and, therefore,
do not accept the Multiple Message Format (default). If this is the
case with your device, use the Single Message Format instead.
• Caller ID will be sent during the first 3-second silence in the ring
cycle. If you change the distinctive ringing cycles, remember that a 3second silence is required for the Caller ID information to be sent. (If
there is not at least a 3-second silence, Caller ID will not be sent).
• Some Caller ID Devices require a 7-digit telephone number. If this is
the case with the device you are using, program the TLS-3B with 7digit numbers.
Using Caller ID Prefixes
Caller ID messages can be changed with one of three prefixes, entered before the
number you are dialing:
TLS-3B User’s Manual
*67 = Private
*87 = Out of area call
*88 = Check sum error
For example, dialing *67 102 will ring Line 2 (assuming the default phone numbers
are used) and change the Caller ID message to a private message.
Dialing *87 102 will change the Caller ID message to an “out of area” call. The
Caller ID display will indicate that the call originated form an area in which Caller ID
is unavailable.
Note: Depending on the type of Caller ID display you are using, if private or
out-of-area feature is invoked, the date and time will be shown, but not the
number or name.
Dialing *88 102 will simulate a Caller ID checksum error. The Caller ID display will
indicate that an error occurred in Caller ID transmission.
Note: Caller ID displays react differently to a checksum error. Some attempt to
display the data, others display “line error”, and others ignore the data. Also,
some Caller ID displays require a 7- or 10-digit number. If this is the case with
the device you are using, program the TLS-3B with 7- or 10-digit numbers as
required.

Visual Message Waiting Indication
VMWI (Visual Message Waiting Indication) is a FSK signal issued by the Central
Office when a customer has a recorded voice message waiting to be retrieved. This
FSK burst is an on-hook signal that is sent after an OSI (Open Switching Interval),
which is a period of silence after some action. The TLS-3B can be used to simulate
the VMWI signal by going off-hook on one of the lines and entering *50 to activate
VMWI or *51 to de-activate VMWI for the other line.
Note: Different manufacturers Caller ID equipment react differently to this
signal. See your equipment manual for details.
*50 = Activates VMWI
*51 = De-activates VMWI
PROGRAMMING THE TLS-3B
The TLS-3B has a long list of features and functions, which a user can configure from
a touchtone telephone connected to either line. The TLS-3B stores two separate
configurations in memory. This enables, for example, two separate groups (such as
Engineering and Sales) to set up and use the TLS-3B for their applications. When
programming and using Setup 1, the Power LED blinks once. When programming
and using Setup 2, the Power LED blinks twice.
All programming commands begin with an asterisk (*) and end with a pound sign (#).
You can cancel a command before it is complete, by entering an asterisk before the
final pound sign. In some cases, a second asterisk many be necessary to cancel the
command. The response from the TLS-3B is three short tones.
Many commands either enable or disable specific functions in the TLS-3B. In all of
these commands, 0 disables the function, and 1 enables it. For example, the command
*10#0# disables the hook-flash detect function. *10#1# enables the hook-flash detect
function.
Commands are broken into two types:
• System Commands affect both lines.
• Individual Line Commands affect only the line being programmed.
While programming a line, its LED blinks on and off at a slow rate indicating
programming mode.
40-400-00032, Rev. B

Page 15
Follow these steps to enter Programming Mode:
1. Lift the handset on one of the telephones.
2. When you hear dial tone, enter **99## for Setup 1 mode, or **98## for
Setup 2 mode.
You hear three short beeps verifying proper program mode access. The Power
LED blinks once for Setup 1 and twice for Setup 2.
When you enter a programming command correctly, you will hear three short tones
(confirmation beeps). If you enter an incorrect command, you will hear alternating
high and low tones (error beeps).
A summary of programming commands is provided on page 17.
