REGULATORY COMPLIANCE

FCC Part 15 Class A Notice: This equipment has been tested and found to comply with the limits for a Class A digital

device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.

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.

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.
