Post by D. KirkpatrickMy sister is getting DSL later this month.
She says that she is getting a combo POTS package and 3.0 Down DSL.
She is in the Union Square section of Allston/Brighton.
Does anyone know where the CO is in that area?
I am trying to figure out how far she is from it so as to get a feel
for possible DSL quality based on loop length.

Most places have a DSL "test" you can perform to check your lines for
expected DSL speeds that can be attained. I'd see if I could find those.
Ask her what company she oredered from.
re estimating wire distance from a CO, it's not very accurate to just look
at a map and judge the actual wirelength between the residence and the telco
CO. Their lines may go in some pretty ridiculous zig-zag patterns all over
the place, plus there may be repeaters and conditioners in the lines that
you won't be able to tell about from maps. So, as the crow flies or the
streets ramble, she might be, say 0.9 miles from the CO, but over 2 miles by
wire. However, she may effectively get half mile operation due to an
amplifier or repeater stragegically placed in the ckt.
The only real indicator is to do a test on the actual line as provided by
that telco to see what you get for the up/down speeds.
You do NOT have to have DSL to make those tests work, BTW; they're
actually aimed at dialup connections who want to switch to DSL.
There are also places that can test the lines from end to end (CO to
residence address) even though they aren't even in the same city. They ARE
indicative, but not super-accurate.
Finally, if the telco gave her 3.0 service, it's very highly likely that
she's within the workable range for their DSL; it's one of the first basic
checks they make before letting anyone sign up for it. Telcos in general
make pretty good recommendations as long as the client isn't ordering them
around. Obviously it's in their best interests to do so.
Also, in doing any testing, make MULTIPLE tests at different times of day
and on different days. Those numbers do vary quite a bit, depending on a
lot of things, but even if you get a range, as long as it's always an
acceptable range, that's good. If it EVER show it goes out, then get away
from it.
