CHAPTER 2: Introduction

2. Introduction

This guide is designed to help you install and use the Line Share 120H. Please

read through this guide and select the installation procedures appropriate for

your specific application before attempting to connect or operate the Line

Share 120H.

NOTE

According to standard industry practice, surge protection is

recommended for use with all electronic devices. A surge suppressor

and/or line conditioning should be used on the input power supply, as

well as the connected telephone line.

Call Waiting: Fax and modem transmissions could be disrupted by the

call-waiting beep tone.

Call Forwarding: If call forwarding is enabled, the Line Share 120H

cannot process calls on that line.

Phone Company Voice Mail: This service is not compatible with the Line

Share 120H. However, standalone voice-mail systems work well with the

Line Share 120H.

We recommend that call forwarding and the phone company’s voice mail

services be discontinued.

The Line Share 120H is a state-of-the-art telephone line sharing device that

eliminates the extra dedicated telephone lines used to operate a fax, modem,

or other telephone devices.

The Line Share 120H quickly directs incoming telephone calls to one of

three appropriate destinations, typically a computer modem, fax/modem, or

fax machine, as well as a telephone and answering machine, or any other

telephone device that responds to a standard phone company ring signal.

Please read through the rest of this guide to learn how to properly install

and operate the Line Share 120H.

LINE SHARE 120H

3. Installation

The Line Share 120H is a single-line device that can be installed on any type

of modular or non-modular system that consists of one or more lines, with

one or more phones. A modular system consists of phone cables that can be

connected and disconnected from a telephone device. A non-modular system

consists of cables that are hard-wired to the telephone device and cannot be

disconnected from the equipment. A telephone installer may be required to

install the Line Share 120H on a non-modular system.

NOTE

Many offices have a KSU or PBX phone system. The Line Share 120H

works with either of these systems. Simply follow the appropriate

installation instructions provided in Section 3.7.

3.1 Unpacking the Line Share 120H

When you open the Line Share 120H box for the first time, inspect the

contents. You should have the following items:

• (1) Line Share 120H

• (1) AC power adapter

• (1) telephone line cord

• This user manual

If any of these items are missing or damaged, call Black Box immediately at

(724)-746-5500.

all calls to the TAD and PHONE ports simultaneously.

3. Depending on the installation, a single line phone, and integrated

phone/answering machine, multiple phones, or a telephone system (KSU

or PBX) can be connected to this port. The Line Share 120H will route all

calls to the TAD and PHONE ports simultaneously.

4. The fax machine must be connected to the FAX/MODEM port to enable

the Line Share 120H to automatically transfer a fax call with a fax CalliNG

(CNG) tone to the fax machine. A computer modem or fax/modem can

connect to this port in lieu of a fax machine.
