I forgot to make myself clear about choking the
WAN side... Well, i don't recall it's been verified
with numbers from other DSL customers but i've
seen a slight improvement in terms of RCO figures
if a ferrite choke was put on the MoDem's phone
cord, near it's casing... This was done with help
from 'DMT' Spectral Response and "Noise" graphs:
i started with twenty runs and then i removed a
turn after each measurement. In the end, i chose
the number of turns that made my graphs better.

It was still a somewhat intuitive procedure, your
results may vary but if it works then why not! On
another hand, i must comment that the seasons
affected the quality of my DSL signal, apparently;
a method which used to work months ago might
happen to bring marginal benefits later, or even
worst: once the phone line is back to normal the
choke might as well become a nuisance itself...]]> http://www.dslreports.com/forum/remark,20720878 Mon, 30 Jun 2008 13:30:08 EDT Re: POTS Splitter changed my life (sort of!) http://www.dslreports.com/forum/remark,20720417 Bicephale : MouHa! Ha! Ha! What a creative solution!

:D

Most fortunately, i won't need to hire that kind of
"worker" myself because i'm moving to another city
soon and there are no poles in the street where my
DSL access can be affected by a latern... I hope i
won't find other nuisance in the backyard, though!]]> http://www.dslreports.com/forum/remark,20720417 Mon, 30 Jun 2008 12:01:45 EDT Re: POTS Splitter changed my life (sort of!) http://www.dslreports.com/forum/remark,20720261 ardo :

Hi Quake110,
Chokes on the filters do help, after all!!!

LOL, you got me convinced to a point where I disassembled 3 defunct PSUs and 4 'hands-free' cellphone boards I had lying around. But then I discovered I had 3 snap-on chokes from a dead photocopier. I put these on my modem's power supply wire, telephone wire, and even the Cat5 (heck!) going to the router. I saw no difference in SNR, however, my IP hasn't changed in 2 days. I still have the 7 toroids, and will try them out when I get my splitter. Thanks for your extensive research!

P.S. I have the same problem with street lights. While I cannot do anything to have the phone lines moved, perhaps I can hire local kids to kill the light. :D]]> http://www.dslreports.com/forum/remark,20720261 Mon, 30 Jun 2008 11:28:04 EDT Re: POTS Splitter changed my life (sort of!) http://www.dslreports.com/forum/remark,20720209 ardo :

I followed your diagram:

And I have to tell you it works. Right now, the SNR is stable and my connection didn't disconnect yet (Before, it used to disconnect every ~40 minutes). Plus, the web browsing appears to be more "speedier".]]> http://www.dslreports.com/forum/remark,20714307 Sat, 28 Jun 2008 21:49:55 EDT Re: POTS Splitter changed my life (sort of!) http://www.dslreports.com/forum/remark,20713137 Bicephale : Hi again Quake110,

I once started a thread which i meant to be short
and yet informative, i described a few tricks there:

The customer's own wiring, Bicephale, 2007-Jun-13

SBrook is right to point out that you can't modify
Bell's wiring but i've demonstrated a "non-invasive"
(reversible) method: slotted metal sleeves such as
these were proven to work in cases similar to ours:

See how it looks once in place, "temporarily" (...):

It's all too clear Bell's practice of installing a phone
line close to power circuits is a pure contradiction in
terms of DSL technology and using a pre-existing flat
(non-twisted) cable only makes this situation worst!

Moreover, guys with a lantern right above Bell's aerial
& flat antenna-cable have absolutely no alternative...

Quite frankly, i must argue the company's decision to
deploy their DSL service using distributed filtering just
failed to account for the problems we're now facing.

Most people's best option would be to get their old
(black bakelite) termination/fuse box replaced by a
proper NID, provided the worker sent to do this will
be smart enough to see & cease this opportunity to
use a proper location, that is... Short of that, one
other solution may include RF interference control:

This is "non-invasive" too and it's not expensive but
the result might depend on the interference's nature.]]> http://www.dslreports.com/forum/remark,20713137 Sat, 28 Jun 2008 15:27:02 EDT Re: POTS Splitter changed my life (sort of!) http://www.dslreports.com/forum/remark,20712942 sbrook : Well, it's possible that you may have interference problems ... BUT you may not. Without the needed gadgetry, it's hard to say whether it's a problem or not.

Also, it's worth noting that you are not permitted to touch Bell's wiring on their side of the demarc. I mention that because I don't want it to appear that the site condones messing around with Bell's wiring. If you choose to move it, on your head be it. Ideally, you should ask Bell to install a NID which makes the interface between you and Bell much clearer.]]> http://www.dslreports.com/forum/remark,20712942 Sat, 28 Jun 2008 14:28:25 EDT Re: POTS Splitter changed my life (sort of!) http://www.dslreports.com/forum/remark,20712867 Quake110 : Bicephale, your telephone wiring is interesting. One of culprit I noticed is the close proximity of my demarc (That old black thing in the photo, if you call that a demarc) to the Electric box.

Should I move the demarc out of there because of the electric interference?]]> http://www.dslreports.com/forum/remark,20712867 Sat, 28 Jun 2008 14:07:27 EDT Re: POTS Splitter changed my life (sort of!) http://www.dslreports.com/forum/remark,20712529 Bicephale : Hi Quake110,

They do make a big difference. If it wasn't for the cost involved everyone on DSL should have one.

Considering how many of us complain about noisy lines, a $30 investment in a POTS splitter makes sense. You can get a Corning SPS-H70-SR1 from anixter.com for about that much. Maybe someone should do a group buy?]]> http://www.dslreports.com/forum/remark,20707888 Fri, 27 Jun 2008 12:54:27 EDT Re: POTS Splitter changed my life (sort of!) http://www.dslreports.com/forum/remark,20707327 psor : I have a model like this :

I just installed a POTS Splitter at my house and it dramatically changed the quality of my line.

I am now able to get a 5mbits profile. Before, 3008/800 was my maximum. I am at 4.8 km from the central.
