Does anyone know how the teleco's make their ADSL servers. As a home project I want to figure out how to make one (using one of my spare routers) and I'm just wondering HOW!?!

So you need a radius server and some edge routers plus a DSLAM to send the ADSL connection along the line, probably some fibre and then the know how to make it happen.
Start off with a DHCP server in a windows environment running a home network.

Adsl has the bandwidth split in two ways.
The first bunch of kilohertz are decicated to upstream channels - so your modem has 8 or so transmitters for upload, and about 80 recievers for download.  

The DSLAM at the exchange or roadside cabinet has the reverse - it has 8 recievers and 80 transmitters.

You cant unfortunatley turn a modem into a dslam.
However you can buy them.

A 48 port dslam will set you back about $6,000 though smaller 12 port ones are only about $1200

Try purchasing from www.dslwarehouse.com 

The typical scenario is that the dslam is configured as an ethernet bridge, so you dont need the radius server etc.

I wonder if i patched my modem into the MDF what sync stats i would get ETC. Would be cool :)

full line speed and 0 attenuation. Unless you use wiring stolen from a 1960 house, but nothing the Barron can't sort,with a trusty master filter :)

I have a large motel where I run the hotspot system. Brick walls everywhere and its impossible to get a wifi signal through.

So we decided to get one of those 12 port DSLAMs and just use it like an ethernet switch. There was buried telephone cable going all over the place between buildings, so it made sense to backhaul the APs using a small dsl network.
If i remember right, over the 50m long spans, with the 30 year old cabling they get something like 20mbits/2mbit up with annex M enabled.

VDSL systems are advertised as "extended ethernet" systems for the exact same purpose.

you can get vdsl bridges for 50mbit linking between buildings (pairs of modems, one set as the CO and one set as the CPE)
or you can get the dslams with multiple ports and use vdsl modems at the end points provided they will bridge.

Mikrotik Routerboard, install Mikrotik User Manager package (Radius), Set up PPPoE server with Radius authentication, connect with PPP client, see how that end works.

Then once that works add your delivery network after that.
