There is no technical way to put multiple houses on a single phone line
unless you share a voice line. DSL is simply a way to send a different
signal across a voice line. In the old days, we used 4 wire connections
for speeds up to 45 meg. You HAD to have a 4 wire connection to get
anything over 56K. A strong signal transmitted along a DSL (2 wire)
path, is what allows for up to 4096K (4Meg). There are a couple of
gotchas here..
1) Your friend was partially right when it comes to sharing a DSL line.
Although no 2 houses are on the same line to the BOB (Break out Box),
From there, a bundle is sent to the CO (Central Office). Once you are
inside the CO, they tend to oversubscibe the DSLAM (DSL Access
Multiplexer) by a ratio of not more than 10 to 1. For each port on the
DSLAM, they have 10 subscribers to DSL. This is the only way they can
break even. However, in the last few years, DSLAM port costs have gone down.
2) DSL Signals will not cross a bridgetap. If there is a bridgetap in
the line from the BOB to your home, no DSL. Only the Engineering
department can request to have this removed.
3) Being Capped comes from having to many retrans and errors. It could
be the distance, which must be less than 18,000 feet, greater distances
will cause errors so they cap the line to allow for less problems.
Sometimes they cap it for testing and never get around to uncapping it.
An ingenius Government regulation allows a mom and pop to sell DSL using
SBC equipment for less than what SBC can charge you. If you pay SBC
24.99 a month, someone can come along and resell trhe DSL service for
21.99 a month and not have to purchase any equipment. The cost to SBC is
what determines the rate you will pay. If SBC has a net cost of 12.05
per DSL line, they can resell service to a ISP for a small profit. If
they offer it to the public, they cannot sell to an ISP for the same
price. Therefore, an ISP would get a good discount and resell the
package to the end user. Thus SBC/Yahoo!
So, the bottom line is that while you have SBC as your DSL provider,
anyone can resell their lines cheaper than them.
