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

receiving machine.

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

The fax ‘handshake’ is the time in which the sending machine’s CNG tones and the
receiving machines “chirps” overlap. This must be for at least 2 to 4 seconds, so the
fax 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 Mode)
The Error Correction Mode (ECM) is a way for the fax machine to check a fax
transmission while it is in progress. ECM transmissions are only possible between
machines that both have this feature. If they do, you may send and receive fax
messages that are continuously being checked by the machine.

machines that both have this feature. If they do, you may send and receive fax
messages that are continuously being checked by the machine.
The fax machine must have enough memory for this feature to work.
When you have an external Telephone Answering Device (TAD) on your fax
line, your TAD will decide the number of rings before the call is answered.
Pay special attention to the directions for connecting a TAD in this chapter.
