| My "Ghetto" demarc
My OLD demarc | 
The Phone Jacks througout my house |
I'm thinking about getting Sympatico again and was wondering what should I change to have a better connection.
If I remember, my SNR was flunctuating from 5 to 16 and my attenuation was 49. |

| If your SNR was fluctuating from 5 to 16, I'd say 99% the problem is your internal wiring. With that mess, I dunno what to suggest but an entire rewire job.

Original Phone Wiring | 
New panel before installation | 
Completed panel installation |
What I did - see pictures for details:
- disconnected all the wiring from the TPD.
- made a new wiring run from the TPD to my desk, using CAT5 networking cable, for better signal. This wiring run will be used exclusivelly for the DSL modem.
- cut a piece of scrap plywood and made a wiring panel for the phone system.
- Reinstalled the TPD and wired the incoming Bell line to it. Wired up the new Modem line to TPD as well. Added a telephone jack at that location, aslo connected to TPD directly.
- plugged in 2 telephone filters back to back into the new Demarc jack.
- connected the rest of the house phone wiring to the output of those two in-series filters. No other filters in use in the house, as all the lines are filtered right at the entry point. 
Happy with the results. My signal to noise ration varies, but I am pretty sure it's something external. Even when it goes very low, I still have full 3Mb/s sync and fast data transfers.
Also noticed that rebooting the modem (SS 6520) seems to improve the SNR resports for a while. |

RG, your wiring is interesting and I'm motivated to do the same. But I have a few questions:
- Is the white box a regular phone jack?
- You used a regular cat5 cable as a phone cable from the TPD (I guess it's the black thing) to the modem? Or, where can I buy a high quality phone cable?
Thanks |

was it dangerous to touch the line directing coming in to ur house. If so how did you manage to deal with it? |

Quake110: Regualr jack
nd Regualr cat5 wire is VERY good for this. You can buy HQ phone wire in you local electronic store (Raybel, Addison, Maddison,....)
Kikimimi: If the phone rings, it can give you a shock, but noting dangerous. Just touch one poll at a time. Dont touch directly the floor. Use RUBBER boots (espicially if its earth, asphalt, metal, ciment and other conductiing materiels. |

HAH, my demarc and phone jacks look almost identical! Well, not the demarc, the demarc is alright, but the phone jacks are those old little oblong blocks.
Internal wiring may be an issue if there is a ground or some sort of section of bad wire in your home. I've seen perfectly stable 5Mbit lines run on setups like that with no problems. It is possible that the issue is related to a bad line, but it could just as likely be due to a bad part of the wire anywhere between your demarc and the CO.

- Yes, The jack is a regular phone jack.
- Telephone service would require CAT3 twisted pair wiring. If you have a good Electrical Warehouse in your area, you could look for that. CAT5 is higher quality yet, as it has to carry network traffic and much higher frequencies. So, it's better, a bit of an overkill (4 pairs of wires, you only need and use one pair for the DSL line).
But CAT5 is guaranteed quality, and becoming easier to find, Home Depot has it, etc. I had some so used it.
kikimimi, as stephen_d mentioned, the voltages in the phone line are never too high - the worst is if it rings, the ring is a solid voltage (54VDC if I am not mistaken, and you sure can feel that).
Some precautions can help you deal with it, like using insulated footwear, and not touching both wires at the same time. Trying to disconnect the incoming external wire and avoiding touching it is a good idea too.:)
This took me a few hours to do, but it is worth it, imo. |

1 edit | Actually its 54VDC for dial tone..
But the ringing generator is like 30-60VAC..
It wont harm you but will sure give you a nice jolt. |

Quick question here...dry loop dsl has talk battery on it with no dial tone? I haven't seen one of these and was curious...anyone have it?

Glen: The dry loop DSL pair has talk battery and dial tone on it, and has a telephone number assigned to it also. You just can't phone out on it and can't make phone calls to it, a message just says "this number cannot receive calls/ this number cannot make calls"
This is how they are doing it in my area 519. Don't know if other areas are different. |

i had that problem i rewired everything with cat5.. bell guy hooked it up to the old box* when i had a digital box lying there was pissed off he took the easy road called back had one of them fix it. Line stats stayed about the same. |

Looks pretty good.
Yeah ringing voltage won't kill you or anything, but you'll certainly know it when it hits you. LOL don't be using your teeth to help splice cable... seen an installer do that once and never again. 
One question (Perhaps I'm missing something) it looks like your "Double filtering" your phones. Any reason for that? I doubt this will be of any big help for signal reasons. At least I've never seen it make any improvement on SNR.
I'm impressed you have battery and tone on a Dry line. Here there's just the DSL signal and that's it. (Actually seen the MUX panel in the CO and it's hooked directly to the DSLAM cross-connect and nothing to the phone switch cross-connect.) But perhaps that's because the DSL in your area is controled by the switch itself. Here the switch (DMS-10) doesn't touch DSL signal. Instead it's injected onto the line from a separate DSLAM unit entirely. For a dry line here it would just be a waste of money and time to cross-connect it to the phone switch. Although they do assign a "Ficticious" phone number to the line just to reference it for billing purposes. |
