2. Introduction
2.2 About the Lineshare Master-4
The Lineshare Master-4 is a state-of-
the-art device that produces a variety
of routing tones on outbound phone
calls. It is designed to work in
conjunction with a modem, fax, or
any type of automatic- or manual-
dial telephone device. The
Lineshare Master-4 allows any fax
or modem device to automatically
route calls through line-sharing
devices that detect fax CalliNG
(CNG) tones, reverse modem tones,
or various single-frequency tones.
The Lineshare Master-4 works best
when installed between the
telephone company’s line and a fax
or modem device. The Lineshare
Master-4 allows connection of up to
48 individual telephone lines, and
up to 48 individual modems (or
other telephone devices). When a
device accesses the telephone line
through the Lineshare Master-4, the
unit pauses until dialing is complete.
It then places the calling device on
hold and transmits a series of user-
selectable calling tones.
When used in conjunction with a
Lineshare Pro (part number FX150A
or FX150A-D48), the Lineshare
Master-4 can access multiple
modem-type devices on a single
phone line.
2.1 Before You Begin

NOTE
We recommend surge
protection for all telecom-
munications devices. Use

3. Installation
• additional telephone cables—
typically supplied with
equipment by the manufacturer.
You need additional telephone
cables (part number EL04M-00)
for as many pieces of equipment
as you intend to connect to the
Lineshare Master-4.
• extension cables—required if the
connecting equipment is not
located near the Lineshare
Master-4.
3.1 Lineshare Master-4 Rack Rear
Panel
The rear panel of the Lineshare
Master-4 Rack has four 24-pair telco
connectors, a one-amp fuse, a power
input port, and a system ground, as
shown in Figure 3-1.
Before you install the Lineshare
Master-4, connect all phone lines
and modems (or other telephone
devices) to the patch panels and
amphenol connectors in their
proper configuration. Although your
configuration may vary, all phone
lines and telephone devices connect
to the Lineshare Master-4 the same
way.
CAUTION
Do not connect all
telephones in an office
environment through the
Lineshare Master-4. During
power failure, the unit will
not pass the telephone line
through to the phones.
To perform the installation
procedures in the following sections,
you may need the following
equipment:
• up to four 24-pair telco cables
(part number ELN25T-0000-MF)
• up to two 48-pair patch panels
(part number JPM002)
