Dial Tone Detection; Telephone Line Interference / Voip - Brother DCP-J125 User Manual

Dial Tone detection

When you send a fax automatically, by
default your machine will wait for a fixed
amount of time before it starts to dial the
number. By changing the Dial Tone setting to
Detection you can make your machine dial
as soon as it detects a dial tone. This setting
can save a small amount of time when
sending a fax to many different numbers. If
you change the setting and start having
problems with dialling you should change
back to the factory No Detection setting.

interference / VoIP
If you are having problems sending or
receiving a fax due to possible interference
on the telephone line, you can change the
compatibility setting, which reduces the
modem speed to minimise errors.

Press a or b to choose
Initial Setup.
Press OK.
c
Press a or b to choose
Compatibility.
d
Press d or c to choose High, Normal or
Basic(for VoIP).
 Basic(for VoIP) cuts the
modem speed to 9,600 bps and
turns off ECM except for colour fax
sending. Unless interference is a
recurring problem on your telephone
line, you may prefer to use it only
when needed.
To improve compatibility with most
VoIP services, Brother recommends
changing the compatibility setting to
Basic(for VoIP).
 Normal sets the modem speed at
14,400 bps.
 High increases the modem speed to
33,600 bps. (factory setting)
Press OK.

Note
• VoIP (Voice over IP) is a type of phone
system that uses an internet connection,
rather than a traditional phone line.
• Brother does not recommend the use of a
VoIP line. VoIP limitations in general can
cause some functions of the fax machine
not to work correctly.
