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.

LINESHARE MASTER-4, LINESHARE RACK
4. Using the Lineshare Master-4
4.1 Setting the Calling Tones
By dialing the * key and one of the
eight allowable digits at the end of a
phone number, you can set the
Lineshare Master-4 to produce the
following tones:
0 = 1000hz tone
1 = 1100hz tone (typically fax
CNG tone)
2 = 1200hz tone
3 = 1300hz tone
4 = 1400hz tone
5 = 1500hz tone
6 = 1600hz tone
9 = 2225hz tone (typically reverse
modem tone)
The factory setting is 2225hz with
the unit turned on.
If all calls from this system are to
transmit the same calling tone, it is
not necessary to enter the * after
each telephone number. The
Lineshare Master-4 retains the
previous command in memory and
will send the same tone on every call.
If power fails, the Lineshare Master-4
will maintain the previous settings
once power is restored.
When a device dials a tone phone
number through the Lineshare
Master-4, the unit starts a two-second
timer each time it detects a tone.
This continues until the two-second
timer expires without detecting a
tone. The Lineshare Master-4 then
places the calling device connected
to the unit on hold. It then begins to
transmit a series of calling tones (the
frequency of the tone depends on
user settings). If the Lineshare
Master-4 detects an answer carrier
from a fax or modem, it immediately
stops transmitting the calling tones
and releases the line to the calling
device.
You can turn the Lineshare
Master-4 on or off using tone
commands. To turn the Lineshare
Master-4 on, press # *. Once you
enter the # * command, the
Lineshare Master-4’s timing registers
are activated. To turn the Lineshare
Master-4 off, press # #.
You can also use tone commands
in the following ways:
• to enter the programming mode
• to set calling tones
• to set timing registers
• to use the Call Hold Function
• to reset factory settings

19
LINESHARE MASTER-4, LINESHARE RACK
NOTE
All of the tones produced by
the Lineshare Master-4 can
be used on an outbound call
for routing purposes.
However, they work best
when used in conjunction
with the Lineshare Pro.
To set the tone frequency for the
Lineshare Master-4 transmissions,
enter the * and a single digit 0
through 6 or 9 at the end of a phone
number. The digit you enter sets the
tone frequency.
For example, pressing * 1 at the
end of a phone number (555-
1234*1) will send a fax (CNG) tone.
This allows the Lineshare Master-4 to
produce CNG tones for a fax
machine that cannot produce the
tone. With the help of the Lineshare
Master-4, your fax machine can
automatically access other fax
machines that use a line-sharing
device to detect and route according
to the CNG tone.
In the same way, pressing * 9 at
the end of a phone number will send
a series of 2225hz reverse modem
tones. This allows the Lineshare
Master-4 to produce reverse modem
tones for modems that cannot
produce the tones. With the help of
the Lineshare Master-4, your modem
can automatically access other
modems that use a line-sharing
device to detect and route according
to the reverse modem tone.
4.2 Using the Reverse Modem Tone
To route through a line-sharing
device using the reverse modem
tone, perform the following steps:
1. Set each modem to normally
send and receive calls. Do not set
either of the modems in the
Reverse Modem mode.
2. Turn on the reverse modem
detection feature in the line-
sharing device that is receiving
the call from the modem/
Lineshare Master-4 combination.
3. At the end of the phone number
in the modem’s communication
software, enter the * 9
command.
4. Place the call using the modem’s
communication software.
The calling modem then accesses
the phone line through the
Lineshare Master-4 and dials the
number of the receiving modem.
The Lineshare Master-4 detects the
* 9 and sets the tone emulation
register to transmit the 2225hz tone.
Three seconds after the last digit (9)
is dialed, the Lineshare Master-4
begins transmitting a series of
2225hz tones.

20
LINESHARE MASTER-4, LINESHARE RACK
When the line-sharing device
answers the call, it detects the
reverse modem tone from the
Lineshare Master-4 and routes the
call to the receiving modem. When
the receiving modem answers the
call, the Lineshare Master-4 detects
its carrier signal and releases the line
to the calling modem. The two
systems then establish their
communications link.

21
LINESHARE MASTER-4, LINESHARE RACK
5. Using the Lineshare Master-4’s
Custom Functions
To change the Lineshare Master-
4’s functions, we recommend using
the following steps:
1. Using Table 5-1, write down the
sequence of changes.
2. Enter the programming mode.
3. Change the functions.
The following sections explain
how to enter the programming
mode and change the functions.
5.1 Using the Programming Mode
To enter the programming mode,
perform the following steps:
1. Make sure that the telephone
line from the phone company is
connected to the patch panel,
and then to the Lineshare
Master-4.
2. Plug a tone phone into the
appropriate RJ-11 jack on the
modem patch panel in place of
the modem.
3. Pick up the phone receiver and
make sure you hear dial tone.
4. Within five seconds, press and
release the * key and then the #
key on the telephone keypad.
The Lineshare Master-4 includes
many options that enable you to
customize its operation to meet
specific application needs. The
programmable functions offered by
the Lineshare Master-4 allow you to
change the length of its tones, time
between tones, time before the first
tone, number of tones to transmit,
and the call-hold feature.
The Lineshare Master-4’s
functions are factory-preset, and it is
unlikely that you will need to make
many changes. However, if you
desire, you can alter any program by
using a tone phone connected to the
appropriate RJ-11 jack on the patch
panel. The Lineshare Master-4
cannot be programmed with a
rotary/pulse dialing phone.
NOTE
Before attempting to
program any function, we
recommend that you first
thoroughly read the
programming procedures.
Then read “Changing
functions” in Section 5.1 and
decide if you want to make
changes.
