I have the following connected to my telephone line from Bell:
- a DSL Modem (Speedstream 6520)
- a Brother MFC-240 Multifunction Printer/Fax/Copier machine
- one Panasonic Wireless Telephone (Base + one extension)
- one extra telephone
The printer is the last addition. I noticed a line noise - a
continous low howl on the telephone lines. I have tried to have the
phones, DSL and printer on a different line. The noise is still there
- it goes away when I remove the printer from the line. I have the
printer and the telephone connected to line filters. I am at a loss in
tracing the source or cause of this line noise. I tried to connect a
phone to the Ext. jack on the printer and noticed that I could not
hear the noise on the extension. But the noise is constant on the
other two phones - Basement and Bedroom.
What els can I check please ?
Check the printer manual, fax section.
It might be that the fax is constantly
trying to communicate (or _thinks_ it's
communicating) over the phone line.
Its default setting may assume it has
its own separate fax line, that it can
signal to any way it wants, when it
It may need to be taught how to to share
with others... :p
The fax will filter out any signals it
generates, to its own phone jack.
If you start to dial out from a phone on
the printer jack, does the noise stop
on the other phones?
I tried to dial out from the telephone on the printer extension and
listened to the other line - the noise was not present ! It came back
as soon as I press the reset dial tone button on the phone at the
fax/printer. This is strange ! Why did the noise disappears when I
was on the phone attached to the printer ?
Because the fax turns off its signal when
the user picks up to make a voice call;
otherwise the noise would annoy the called
party. It can't detect other phones on the
Have you noticed the noise on the line
if someone dials in, and you answer on
another phone? It may shut off after a
second or so if it does not detect an
incoming fax signal.
The fax is definitely the source of the
signal, and I'm willing to bet there is a
machine setting to turn it off.
Read your manual carefully, especially the
fax section. Probably something like
'autoanswer enable/disable' or 'autodetect
fax on/off' or some such tech-speak.
The other option is to connect all the
other phones to the fax's phone jack! :)
Perhaps even a software setting also (if the PC is running).
The OP can check the RJ connector and see if something is bent or

I have ordered a DSL Line Splitter to connect to the mail telephone
lines. Apparently this splitter will separate the DSL line at the
source and the other telephone line could be connected to the voice
line which is filtered. It will remove the need to have a filter on
each telephone line. It will separate the DSL circuit from the rest
of the voice lines. I'll provide an update when this has been
completed this weekend. I will also try other settings for the fax

I installed a DSL Splitter made by Suttle that separated the voice and
data lines. I then had a dedicated line to the DSL Modem from the
Data Port of the Splitter and the phones and fax machine on the
separate voice lines. I had a connection jack for the voice lines that
fed each telephone extension.
The noise is gone, the DSL speed and fax machine works fine. The
splitter had a built-in filter for the voice lines so that I do not
need filters on each phone extension anymore. Looks like a bad
connection somewhere, but the rewiring solved the problem .
Thanks guys for your suggestions.
