Well there are a couple decent sized CLECS still around. DSLExtreme is a
CLEC. Speakeasy is a CLEC (though I think they got bought by BestBuy as
I recall. Kind of a weird purchase.). But yes MegaPath is the remaining
CLEC that does any serious business with a national foot print.  (I
think DSLExtreme is only in CA). Not sure about Speakeasy.

The CLEC craze was well documented in a book called
CLEC: An Insiders Look at the Rise and Fall of Competition in the Local
Exchange Competition
(http://www.amazon.com/CLEC-Insiders-Competition-Local-Exchange/dp/0897254708/ref=sr_1_1?ie=UTF8&qid=1294177906&sr=8-1)

I have a copy. Shipped from the author and signed by him. It's a fairly
rare item these days. Yes I'm that big of a telco geek that I have the
only book on the CLEC salad bowl days on my bookshelf. Right next to
books about DSL and SS7.

Sure. Most peoples homes/MDU aren't within 500 feet of fiber that could
support those connections, and as such the construction costs would be a
killer. Lots of people are on an access network (FiOS/Uverse), but that
can't get you l2 access/bgp etc (at least not to my knowledge).

I happen to be within 500 feet of ATT/TimeWarnerCable gigabit fiber. If
I wanted to pay the fees, I could get a direct fiber connect turned up.
However it's too exorbitant of a cost, until I become a CLEC, then the
dynamic changes considerably. :)

Well SDSL/T1 are viable options. SDSL being more so due to the lower
cost, and the substantial effort put into your SDSL CPE.

On the one hand a direct buy makes sense. On the other hand, a CLEC can
put more pressure on the ILEC in times of an infrastructure issue. The
CLEC has an entire customer base behind it, so it's complaints carry
serious weight. Not to mention things like actual SLA. (I have spent way
too much time reading over ATT/Verizon CLEC information).

Hmmmm. That's interesting. Calling it ethernet is misleading. Unless
they are providing l2 access, site to site connectivity etc (ie metro
ethernet offerings). You can do this with DSL (there are MPLS offerings
over DSL).

 T1 or up to 4x bonded T1.  This stuff they

Wait.... what does Covad/MP own? They don't just lease
infrastructure/space/copper plant (unbundled network elements) from the
ILEC?

Right. Well there are certain advantages to going through a CLEC. Like
not having to navigate an awful IVR, and getting sales people to call
you back in less then three weeks.

Customer service. Really that's what it comes down to. Also some amount
of competition is required, otherwise the feds start looking at ATT/VZ
too closely. :)

It doesn't appear to be from the web interface:
https://smallbusiness.bellsouth.com/form_order_dsl_direct13.aspx

(it used to be an option on that page)

Right. Unbundled network elements. Layer 1 operator being the ILEC, l2
and above being CLEC.

Got it. Something like

Got it.
