ECM (Error Correction Mode), Stop/Exit - machine

Page 27 highlights

The receiving fax responds with fax receiving tones-loud, chirping sounds. A receiving fax chirps for about 60 seconds over the phone line, and the LCD shows RECEIVING. If your FAX/MFC is set to the FAX mode, it will answer every call automatically with fax receiving tones. Even if the other party hangs up, your FAX/MFC continues to send the "chirps" for about 40 seconds, and the LCD continues to display RECEIVING. To cancel the receiving mode, press Stop/Exit. When your FAX/MFC answers in FAX/TEL mode, it 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. Note 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 for connecting a TAD to your FAX/MFC in Chapter 2, Assembly and Connections. 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/MFC for this feature to work. INTRODUCTION 1-8

The receiving fax responds with fax receiving tones
loud, chirping sounds. A
receiving fax chirps for about 60 seconds over the phone line, and the LCD
shows
RECEIVING
. If your FAX/MFC is set to the FAX mode, it will answer
every call automatically with fax receiving tones. Even if the other party hangs
up, your FAX/MFC continues to send the
chirps
for about 40 seconds, and the
LCD continues to display
RECEIVING
. To cancel the receiving mode, press
Stop/Exit
.
When your FAX/MFC answers in FAX/TEL mode, it 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.
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/MFC for this feature to work.
Note
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 for connecting a TAD to your FAX/MFC
in Chapter 2,
Assembly and Connections
.
