Re: [Troubles] Upgraded to 6 Mbps and Having Trouble
Hey, found the SNR and Atten right where you said it was the first time.
Again, thanks for the help

| There is no way you are going to get 6M with those stats at 1.5. SNR is too low, attenuation way too high.
Make sure you have filters installed on every single device on your phone lines, including any satellite boxes or anything else. I would recommend testing your signal stats while plugged directly into the test jack inside the NID (gray box on the side of your house where the phone line comes in) |

With attenuation of 42, you should be on the edge of 6 meg capability, if you are on adsl2 service, and the local copper loop has the right qualifications. The SNR can can be tweaked a little higher, no big deal. Once again my advice to everyone who is frustrated with the business office, get a hold of a local tech, or a local manager who can direct a tech to you, 99% of the local folks will bend over backward to accomidate all of youre needs. |

| hey shadow, sorry to get off topic, well, kinda, but you say 42 is on the edge. what is in the clear??? higher or lower?? thanks.
Smurf: here is a number w/ tech support in the states. 1-866-990-3282....but i think it's the dedicated tech support |

Lower is better for attentuation. Higher is better for SNR (Signal to Noise Ratio, or how loud the signal is to the noise on the line, also called noise margin.)
I will defer to shadow on the 42 being on the edge thing. I would be leery about it, but he does this for a living.  |

Basically what BSC said, I define attenuation as the natural resistance to data flow on youre copper loop. And its directly proportional to the distance of youre line from the dslam, With 0 db of attenuation at the dslam to about 35-36 which is about 7.5k ft to 8k ft out. 8000 ft out is the absolute farthest out I've ever seen 6 meg DSL work, with only 6500 ft being the max for 12 meg( so far) that I've seen. There is very little we can do for attenuation, it is what it is. SNR is the strength level of the data cirquit on the copper loop, and is directly proportional to the attenuation. We can tweak that measurement quite a bit, by conditioning the line, adding nid filters, or replacing bad modems. A good SNR value for 6 meg is in the teens. A good study tool is basic electrical theory, ohms law, resistance, capacitance etc, all of these factors are relevant to the phone lines and data transport over the copper. |
