Cable vs. DSL
Wow, this has been an interesting weekend. My DSL was down all weekend. I lost sync early Saturday morning and basically didn't get it back until Monday around 10 am. During that course, I noticed all sorts of noise and interferrence on my phone line. That's when I realized all of the previous posts I made regarding my connection was due to this noise I was hearing.
I called SBC and they ran their remote tests and said that everything looked fine. I (unfortunatly in hindsight) had a telco tech come out and check my line. I found a pattern of my line having problems during changes in temperature, ie...night time and day time. He couldn't find anything wrong with my line. No shorts, high-opens, nothing. Well, after he was convinced that the static I heard on my line was due to my DSL, testing this theory at my NID, he left.
Something still bothered me, though. I went and grabbed my ladder and tools to check my NID again...and low and behold, I found the issue. I had about 4 inches of exposed wire that connected to the phone terminal that was untwisted! Twisting prevents interference such as cross-talk, a symptom I was seeing, among other types. This also really affected my line. When something interferes with the voice portion to the point of causing serious voice disruption, it will affect the DSL signal.
Of course I twisted those wires up nice and tight and since then, my connection has been rock solid. My downstrean attenuation (the measurement that is of most concern) even increased 2dB...which is a huge gain.
