About fax machines
Fax tones and handshake
When someone is sending a fax, the fax
machine sends fax calling tones (CNG
tones). These are quiet, intermittent beeps
every 4-seconds. You’ll hear them after you
dial and press Mono Start or Colour Start
and they will continue for about 60 seconds
after dialling. During that time, the sending
machine must begin the “handshake” or
connection with the receiving machine.
Each time you use automatic procedures to
send a fax, you are sending CNG tones over
the phone line. You will soon learn to listen for
these quiet beeps each time you answer a
phone on your fax line, so you will know if you
are receiving a fax message.
The receiving fax responds with fax receiving
tones, which are loud, chirping sounds. A
receiving fax chirps for about 40 seconds
over the phone line, and the LCD shows
Receiving.
If your machine is set to the Fax Only mode,
it will answer every call automatically with fax
receiving tones. If the other person hangs up,
your machine will continue to send the
“chirps” for about 40 seconds, and the LCD
continues to show
Receiving. To cancel
receiving, press Stop/Exit.
The fax ‘handshake’ is the time in which the
sending machine’s CNG tones and the
receiving machine’s “chirps” overlap. This
must be for at least 2 to 4 seconds, so both
machines can understand how each is
sending and receiving the fax. The
handshake cannot begin until the call is
answered, and the CNG tones only last for
about 60 seconds after the number is dialled.
So it is important for the receiving machine to
answer the call in as few rings as possible.
ECM (Error Correction Mode)
The Error Correction Mode (ECM) is a way for
the machine to check a fax transmission
while it is in progress. If the machine detects
errors during fax transmission, it resends the
pages of the fax that had an error. ECM
transmissions are only possible between fax
machines that both have this feature. If they
do, you may send and receive fax messages
that are continuously being checked by the
machine.
Multi-Line connections
(PABX)
Most offices use a central telephone system.
Brother recommends that all our Fax/MFC
machines be connected to a discreet
(dedicated) line. Although a particular PABX
may appear to work with a particular model of
fax machine, we cannot guarantee that the
unit will operate correctly.
While it is often relatively simple to connect a
fax machine to a PABX, (Private Automatic
Branch Exchange), we suggest that you
contact the company that installed your
telephone system and ask them to connect
the fax machine for you.
Brother does not recommend the use of a
PABX line. PABX limitations in general can
cause some functions of the fax machine not
to work correctly.
