Re: Help/Advice with my Line Statistics please
Even though it was only one particular phone that picked up "hiss" on the phone line, I can't help but think about if can hear "DSL hiss" on that line, I bet it's possible that any noise that is prsent along the way could travel back through the line that the single filter couldn't prevent from being fed back to the dsl modem. So far, only 2 upstream FEC's over 15 minutes which is definitely lower than my previous averages. Only time will tell if the modem cares about using 2 microfilters in the basement instead of 2.
I came across the the filter/splitter in my stash. I'm kind of curious if I should implement it's use. It looks like something that would probably be best served being used as a demarcation point. I guess I could term that middle jack as a "line out jack" of sorts which I could use to plug in that extension cord that helps my connection. Too bad I'm not sure if it maters where I plug that extension cord in. Also, I'm not entirely sure if that jack in the middle of this wall mountable block is filtered or not (I would want it to be NOT filtered for my unique purposes). |

I have one that looks just like that, the front middle port is filtered, this filter is intended to be used with a wall mounted phone the odd thing about this wall phone filter is its just a dual port microfilter

said by Bicephale  :What do you plan to do with the "Z-Blocker" outlet??? was thinking of possibly using it as an indoor demarcation point but now that I think of it, it just looks like a splitter and filter built with a peice of plastic around it for wall mounting. I would have had to plug into an already existing jack which would have accomplished nothing. I think that I was possilby mistaken and was just getting my in/out directions mixed up and was thinking that one of the "outs" was an "in" which would have made it a good centralized test point.
I just look at my error rate for the past few hours and it averaged out to about the same as before. Oh well, at least the hiss is gone from the voice phone now. |

Hi WayJac,
What's nice with your post is that if someone asks for short
patch cords now we know one place where to look for them!

| Its been years since I've seen a modem kit that included the the wall mount filter in my other post
Now days the wall mount filter is not included with the modem if one is needed it must be requested and it will be something like the one below

1 edit | Hi eveyone,
Years ago when I was with AEI Internet, I was looking all over the place for those wall mount filters and I couldn't seem to find one. Finally I decided to try a Bell World store. Even though the only products they had visible were cellphones at the time, the guy I talked to went into the back and emerged with one of these about 15 seconds later. He handed it to me and said I could have it.
I use it for my old purely wired wall phone that works with or without electricity. I haven't opened it up to see if it's just a small microfilter with the plastic plate around it, or if it has its own electronics. I'll open it up when I get home and report back  |

may tell us how many "poles" this filter has...

I know it's probably not what it's causing errors on your line.
You should remove the old protector with no fuse in it, it happened a few times to me that those old protector caused some noise, I even saw one that caused a drop of 3mbps even with no fuses and no grounding on it. I think that I still have that one in my truck as a keeper...
I don't know why but everytime I find something that has spectacular/funny troubles i'm keeping it and identify it... Those are like small trophey. |

| That looks like a 1st order low-pass filter but
the PC Board was designed to be populated
with optional components which would turn
it into a two poles filtering device... Perhaps
a hobbyist who owns two of those might be
tempted to combine them to get something
roughly equivalent to a POTS splitter but in
a wall-mount outlet, euh... Please don't ask
me if it's worth enough to bother though!...
Too bad these short cords aren't terminated
on both ends, in any case.

1 edit | bicephale, I think you know very well that I was hinting at the error rate.
I could just be a big coincidence but last night I took some of the phone wiring that comes into my room and bundled the excess into a bundle with an elastic. I know.... I know... it would probably be better to just cut it but have extra wire/slack gives me a little more flexibility where to place the phone jacks, phone devices, and modems. This isn't the jack that feeds my modem but it does run this wire does run alongside the wire that feeds the jack to my modem.
This morning I started noticing a crazily low error rate. I'm talking about 2 FEC's in a period of a 3 hours based on the fact that the DMT counter wasn't changing. So I started playing around a bit and thought that the phone wiring must have been transfering noise to my modem because I had just had the excess wire shoved underneath my desk beside some speaker and electrical wires.
A few hours after that, the error rates returned to normal so I started wondering that maybe I didn't find the source of noise after all. So now I'm really not sure what to think. Why would noise just suddenly decide to take a 5 hour vacation? |

Hey dslrocker3, want to switch lines with me ? I am sure you would love to tweak my 1728/640 fastpath line...  |

1 edit | said by Mauricio :Hey dslrocker3, want to switch lines with me ? I am sure you would love to tweak my 1728/640 fastpath line... Sure, why not!? But I think that Oinktastic was in line first. Here I am worrying about 10 or so CRC's per hour but either of you will be glad to take that. LOL. Besides, you forget that my line was set to 1728/640 interleaved, 2496/800 fast path, 2496/800 interleaved, 4032/512 interleaved (never actually synced that high), and then 1728/640 fast path for a few days until they transfered my line and set me to 5056/512 interleaved. That 5056/512 profile last for about 5 minutes while I argued for an 800Kbps upload profile and now I'm on 6016/800 Kbps fast path. |

Hummm...
Quite frankly, i doubt even a five hours noise vacation
will make a significant difference in your specific case!
