Custom features on a single line.
If you have Call Waiting, Call Waiting/Caller ID, RingMaster, Voice Mail, an 
answering machine, an alarm system or other custom feature on a single phone 
line with your machine, it may create a problem sending or receiving faxes.
For Example:
Your Brother machine handles the Caller ID subscriber services.
However, if you subscribe to 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 faxes. 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.
