Hmmm unlikely I think.
The Zhone box for instance seems to be around 11,000$.

> Basically, you put the "switch"-DSLAM in the network cabinet where the copper wires go, you connect the wires to it, you connect the ethernet port to your LAN (so your FS). In each room/office, you plug an adapter (provided also by Phybridge) which is basically a small ADSL modem (powered from the switch through the wire), from which you get an ethernet port, with POE on it!
