High Speed DSL

February, 1997 -- I am on pacbell.net dialup. How long before I cannot remember, but I was a beta tester for PBI and was using it a month before it went public.

December, 1998 -- I learn about DSL, with it's loop limit of 18,500 feet. I measure my line at over 19,500 feet -- I am disallowed DSL.

December, 1999 -- Pacbell ignores the limits and offers me DSL, I have it installed on December 29th, 1999.

Early 2000 -- the DSL is up/down quite a bit, they remove half taps and such, I add a Cayman 3220H, my DSL is running 768/128 on a 20,400 foot loop.

Over the years, my speed has dropped and is often in the low 600's. This morning, with the cables cool, I'm blazing at:

Current Rate : 736 Kbps 352 Kbps
Maximum Rate : 736 Kbps 366 Kbps
Noise Margin : 5.5 dB 6.0 dB

However.... They went and got the RT up and working without telling me. I ordered DSL for the other 'phone line and it is getting:

Downstream Rate: 5472 kbps Upstream Rate: 768 kbps
Current Noise Margin: 6.0 dB (Downstream) 18.0 dB (Upstream)

more than seven times faster incoming and two times faster outgoing. And that is with the line running all over the house with mico-filters. Should hit the 6 meg max when I switch to the NID splitter.

Not to mention that by putting the DSL on my new phone line (new meaning I got it in '86 when I married Wendy) I can disconnect the old (installed in 1970) phone line and will end up saving a few bucks a month.
