How are telephone layouts set up for DSL? |
|
|
I did some investigations with http://maps.google.com ... I took a bunch
of phone numbers from local stores and neighbors' to look at DSL
availability on Verizon's Web site. I wanted to see a pattern in who can
get DSL. I do see a pattern. It appears that DSL service is available
before (north of it) there is a major street (3 lanes on each side).
Below it (south), no one can get it even the Mariott hotel!
Is there a specific layout how telephone lines are laid out for DSL
service and requirements? Or is there something in the street to make
this DSL availability a show stopper?
FYI, Verizon says I am about 20K ft. from the CO. Everyone, at homes,
can't get it either even the next door neightbor with the same main
street.
Thank you in advance. :)

Sounds like you are right near the edge of availability, which is
roughly 18kft (give or take 2-4kft).
Telcos don't run cable out in a huge spider-web of wire. Its not very
cost effective to do something like that.
Instead they run out cable in a tree pattern, with huge feeder trunks
splitting off to smaller trunks, and eventually down to the leaf nodes
around the houses.
Things like major roads, railroad tracks, lakes, rivers, etc. are
planned around, because its not easy to go through these things, and
the major trunks tend to stay away from natural features like this,
both for cost, as well as disaster recovery.
Thus, the people across the major road probably are fed off a
different trunk line than you are. Yours could backtrack quite a ways
out of the way on its way back to the CO crossing the major road at an
easy-to-get-across point.
That extra distance is probably what puts you over the limit while the
people across the road can get it.
Your best hope is probably to hope for the telco to install remote
DSLAMs in remote locations where your trunk feed is going through.

Interesting. Too bad the public do not get to see this layout. Is there
a way to convince Verizon to add more remote DSLAMs in remote locations?

Well, the public don't get to see a car made usually either.. But
yeah, I know there's usually a bit more interest in finding that out.
I guess the best way would be to call up and complain and just make a
pest of yourself. If they get enough demand, they should start
thinking of doing something like that. |
