On my activity report, under comment is states TX ECM I know the TX is transaction (I think?) what does ECM stand for
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.ECM (Error Correction Mode) Detects errors during fax transmission and resends the page(s) that had an error.
If you have Call Waiting, RingMaster, Voice Mail, an answering machine, alarm system or any other
custom feature on a single phone line with your fax machine, it may create a problem sending or
receiving fax data.
For Example:
Your Brother machine handles the Caller ID and Call Waiting/Caller ID subscriber services.
However, if you subscribe to only Call Waiting or some other custom service and its signal comes
through the line while your machine is sending or receiving a fax, the signal can temporarily interrupt
or disrupt the fax data. Brother's ECM feature should help overcome this problem. This condition
is related to the telephone system industry and is common to all devices that send and receive
information on a single, shared line with custom features. If avoiding a slight interruption is crucial
to your business, a separate line with no custom features is recommended.
