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 Start and they will continue for

about 60 seconds after dialing. 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 dialed.

So it is important for the receiving machine to

answer the call in as few rings as possible.

ECM (Error Correction M ode)

The Error Correction Mode (ECM) is a way for

the machine to check a fax transmission

while it is in progress. If the machine detect s

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.

If this feature stops working, delete your

faxes from the memory.
