When your fax machine answers in FAX/TEL Mode, the fax machine listens for CNG
tones and then responds with receiving tones.
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
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. Therefore, it's important for the receiving machine
to answer the call in as few rings as possible.
When you have an external telephone answering device (TAD) on your fax line, your
TAD will determine the number of rings before the call is answered. Pay, special
attention to the directions in the Installation chapter for connecting a TAD to your fax
machine.
ECM (Error Correction Mode)
The Error Correction Mode (ECM) is a way for the fax machine to check the integrity
of a fax transmission while it is in progress. ECM transmissions are possible only
between machines that both have the ECM feature. If they do, you may send and
receive fax messages that are continuously checked for their integrity.
Sufficient memory must be available in your fax machine for fills feature to work.
