LINESHARE MASTER-4, LINESHARE RACK
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.
