Bearing in mind that the facilities that exist in much of the rural
united states are actually there  because we collectively payed for them
rather than simply:

        waiting for the right set of economic incentives to exist

        or leaving people to suffer.

It not unlikely in some cases that the economic incentive for universal
service may never exist may never exist in some  reasons which doesn't
mean that we shouldn't do something about it.

At my last job we built out a fiber to the home ILEC in relatively
rural Louisiana. This means that we had quite a number of customers
that didn't meet the density requirements for deployment. Using 
made-up numbers for the sake of discussion, lets assume that a
customer provides $1/month for service. If you can place deployment
in a highly-dense area you'll make a lot more of those $1's per month
with that investment. When you start deploying further to the edge
you really slide into the "we're not even breaking even on this"
market. Obviously anyone that has a job for profit knows that this is
a no-no.

As telcos deploy high-density technologies (fiber, metroE, etc) they
can pull the legacy technology (xDSL, T1, etc) and push that to the
edge. Unfortunately the edge is always going to get the hand-me-downs
but it's better than nothing. My wife is from a tiny town in central
PA (the vortex between Pittsburgh and Philly) and her parents have
had dialup until last year, when the local telco finally pushed DSL
to their location. They only draw 1.5meg but it's better than the 56k
they were paying for.

As they say in vegas, "It's just business, baby."

It's not great, but considering the alternatives (33.6k dialup for
$60/mo or satellite broadband for $150-$200/mo) it wasn't a bad
deal for my dad when you consider that the dialup ISP + dedicated
POTS line cost about as much as the 5GB 3G data plan does.

Speed is somewhere between  dialup and Uverse or FIOS.  I get the
sense that it is somewhere in the range of 256 - 512 kbps with high
latency (Dad's not one for much in the way of network performance
testing).

Hmm.  Although I've never been to Western MA and hence have no
idea what the telecom situation is like over there, I'm certainly
aware of quite a few places in "first world USA" where DSL is
still a fantasy, let
alone
fiber.

As a local example, I have a friend in a rural area of Southern 
California who can't get any kind of "high-speed Internet".  I've
run
a
prequal on her address and it tells me she is 31 kft from the CO.
The CO in question has a Covad DSLAM in it, but at 31 kft those
rural residents' options are limited to either IDSL at 144 kbps
(not much point in that) or a T1 starting at ~$700/month.  The
latter figure is typically well out of range for the kind of
people who live in such places.

That got me thinking: ISDN/IDSL and T1 can be extended infinitely
far into the boondocks because those signal formats support
repeaters. What I'm wondering is how can we do the same thing
with SDSL - and I mean politically rather than technically.  The
technical part is easy: some COs already have CLECs in them that
serve G.shdsl (I've been told that NEN does that) and for G.shdsl
repeaters are part of the standard (searching around shows a few
vendors making them); in the case of SDSL/2B1Q (Covad and
DSL.net) there is no official support for repeaters and hence no
major vendors making such, but I can build such a
repeater
unofficially.

The difficulty is with the political part, and that's where I'm
seeking
the wisdom of this list.  How would one go about sticking a
mid-span repeater into an ILEC-owned 31 kft rural loop?  From
what I understand (someone please correct me if I'm wrong!), when
a CLEC orders a loop from an ILEC, if it's for a T1 or IDSL, the
CLEC actually orders a T1 or ISDN BRI transport from the ILEC
rather than a dry pair, and any mid-span repeaters or HDSLx
converters or the like become the responsibility of the ILEC
rather than the CLEC, right?

So how could one extend this model to provide, say, repeatered
G.shdsl service to far-outlying rural subscribers?  Is there some
political process (PUC/FCC/etc) by which an ILEC could be forced
to allow a
third
party to stick a repeater in the middle of their loop?  Or would
it have to work by way of the ILEC providing a G.shdsl transport
service to CLECs, with the ILEC being responsible for the
selection, procurement and deployment of repeater hardware?  And
what if the ILEC is not interested in providing such a service -
any PUC/FCC/etc political process via which they could be forced
to cooperate?

Things get even more complicated in those locations where the CO
has a Covad DSLAM in it serving out SDSL/2B1Q, but no other CLEC
serving G.shdsl.  Even if the ILEC were to provide a G.shdsl
transport service with repeaters, it wouldn't help with
SDSL/2B1Q.  My idea involves building a gadget in the form factor
of a standard mid-span repeater that would function as a
converter from SDSL/2B1Q to G.shdsl: if the loop calls for one
mid-span repeater, stick this gadget in as if it were that
repeater; if the loop calls for 2 or more repeaters, use my 
gadget as the first "repeater" and then standard G.shdsl
repeaters after it.  But of course this idea is totally dependent
on the ability of a third party to stick these devices in the
middle of long rural loops, perhaps in the place of loading coils
which are likely present on such loops.

Any ideas?
