1 edit | My OLD Wiring
Here are some pics I took of the old Bell stuff in my house. I dunno if I can really do anything to this. I would like to improve my stats for my DSL im currently on 3mb but I dont think I will be able to handle 5mb. Im currently trying to get a new modem as Im pretty sure some of my bad stats has to do with that.
Modem: Gnet BB0050
Downstream :
Noise Margin : 25.5 dB
Attenuation : 19.5 dB
Output Power : 21
Upstream :
Noise Margin : 3.5 dB
Attenuation : 19.0 dB
Output Power : 9
Thanks for the help  |

Yes, 3.5 dB of noise margin on the upstream is bad. Do you have frequent disconnection ?
Also the output power is a bit too high @21 in downstream. Probably because you are far from the CO.
Are you plugged directly into the demarc ? If so... your only option is asking bell to change the coppers between your demarc and the telephone post. If not, try to connect yourself a new cable into the demarc.

| Guys, he's got 25dB SNR on the downstream, and the attenuation is 20dB which is pretty damn good, why do you think he wont be upgraded to 5meg? Upstream might be a problem with inside wiring, but if its stable now then whats to worry, upstream wont change with 3008/800 to 5056/800 upgrade.

You are right for the downstream. The stats are pretty impressive. I am only worried about the upstream noise margin which is barely twice the natural noise on the line.
There is probably something like other wires in the cable running alongside your wires, interference from power cables, radio signals, higher than normal resistance joints in the telephone wires and damp in the wires or cables. |

Last time i checked I'm around 2.9km's from the CO.
I do get disconnections but only once in a while. I ran some tests before and my lines ended up being ok. I tried my friends DSL modem and apparently the stats got better, at least thats what my ISP told me.
I was thinking of getting a new Modem but not sure, I dont want to get a new Modem if they will upgrade my line the way it is. Then if it runs the way it is just @ 5mb then i'll be happy if not then i guess I would go grab a new modem to fix the problem.
I would like to run a new line to my room but, for me to get at the demarc is pretty hard because its in my celling in the basment and my house is all finished lol. So very small hole to get at it We will have to see.
Thanks for the help all |

So you guys think I should get the 5mb Upgrade with my current line stats??

Gatineau, QC | Wait a second here, did anyone say here what was his exact _current_ profile?
It might be 3mb yes indeed, but what if its 3008/512 or something? Correct me if I'm wrong but I don't thing the 5056/512 profile exists. |

Bell's Heat Coils | | | 
Western Electric No. 58AWE |
I was curious more about the apparatus behind your
wires than the wires themselves so i tried hard to
identify it and here's what i've found. This is a
device which used to be called: "Five Pins" "Heat
Coils" (try that with Google, you'll get details).
In modern terms we call it a Lightning/Surge/Over-
Voltage protector... The porcelain base holds two
fuses with heat coils (7A or so), a pair of carbon
blocks (which i had to wonder if it's not the same
item simply named differently) and a gas-discharge
tube (under a cylindrical hood). Two types shown.
To some people, a word such as "coil" should "ring
a bell" right away, so to speak!... Imagine, your
signal is routed through something that's probably
nothing more than 2 heavily parasitic carbon coils
with a gas bulb across the lossy network (behaving
as a capacitor, i'll bet)! Euh... My 1st action,
if i were you, would be to get the museum artifact
removed - pronto!!! Only then i'd go shop around.

hahaha, Thanks for the info thats pretty cool. The fact that there is gas in there does not make me feel any safer lol.
Well, the problem about us removing that "Museum Artifact" is that my basment is finished so for them to get at all this they would have to start breaking things then my dad would break me lol
SO far now i'll leave it unless it stops working.
As for my profile im on Fast 3000k/800k I have checked using my modem so it should be correct

Actual setup | 
1st operation | 
2nd operation | 
Result |
1st of all, the gas used for electrical devices is
most likely inert (choose your pick: Argon, Neon,
Xenon, etc.); only the terrorists put combustible
gas in electrical bulbs!!! As for your difficulty
to reach this post-war apparatus, euh... it seems
you had at least a minimum of access to it since a
set of photo shots were taken, after all. If this
clearance is sufficient for unscrewing four of the
bolts (those in the corners) then one will be able
to get rid of parasitics, completely (electrically
speaking)! Here's how: simply bypass the carbon
rods by moving one pair of wires to the other side
then take the lightning arrester out of its socket
if it interferes with the ADSL signal at all. I'm
inclosing drawings to illustrate such a procedure.
An other way to solve this may be to insert short-
circuits parallel to the carbon rods - effectively
removing associated parasitics from the circuit...
You probably seen this being done in the espionage
films before: the guy uses aligator clips on both
ends then he cuts in between (no need for doing it
here, though). That's it. Of course, this is the
responsability of Bell Canada to remove these long
forgotten gremlins but something tells me they can
not send you a technician this imaginative, euh...
Oh, and don't worry too much if you must decide to
remove the lightning arrestor because there should
be none in an installation done after the sixties,
as i recall. Good luck, BryanViper! Have fun!...

| Thanks for the info. I dont know if im going to do this because I really dont have much room to work. The reason why I got this pictures is because I stuffed my Digital Camara up there which does not even allow me to put it all the way in unless I put the camara Vertically.
SO that gives you an idea of how small the opening is.
But I will save these pictures just in case I ever do decide to do this. Thanks |

Alligator Jumpers | | | 
Alternative Solution |
BV> ...I stuffed my Digital Camara up there which
BV> does not even allow me to put it all...
Oh, i see. Then that's definitely a case where it
is better just to use a pair of alligator jumpers!
The photographs don't allow me to judge if you can
reach the far ends of the carbon rods but, if that
is possible, then you still have an alternative!!!
Avoid busy hours when the phone may ring or you'll
have you fingers near a potential yet intermittent
90 V.A.C. source... Medium-size alligator jumpers
should do just fine, especially those found in the
vehicle industry (auto/boat/bicycle 12 V clips) as
they'll be sturdier enough to handle large binding
posts and many of them are also isolated properly.
Bring your wireless phone with you if you got one,
it will help while you short the pesky heat coils!
Of course, crossing the wires is a bad idea but it
will work nicely if you follow the schematic. The
jumpers can't hurt quality if their length is kept
to a minimum; when installed as shown, your audio
level may even seem to improve slightly, actually.
There might be degradation introduced by corrosion
after a couple years... If the shorts become less
efficient then a part of the parasitics may happen
to resurface, which wouldn't be as bad as what you
have now. Moving the clips will cure the problem.
P.S.:
The pictures with alligator clips serve the
purpose of showing insulation quality only.
