Brother FAX-2440C User Manual page 175

Before you choose the ring pattern to register
You can only register one Distinctive Ring pattern with the machine.
Some ring patterns cannot be registered. The ring patterns below are
supported by your Brother machine. Register the one your telephone
company gives you.
1 long-long
2 short-long-short
3 short-short-long
4 very long (normal pattern)
@,/If the ring pattern you received is not on this chart, please call
your telephone company and ask for one that is shown.
m The machine will only answer calls to its registered number.
m The first two rings are silent on the machine. This is because the
fax must ,4isten,, to the ring pattern (to compare it to the pattern
that was 'registered'). (Other telephones on the same line will
ring.)
! If you program the machine properly, it will recognize the
registered ring pattern of the 'fax number' within 2 ring patterns
and then answer with a fax tone. When the 'voice number' is
called, the machine will not answer.
