A DSLAM serves internet to a couple dozen computers on a small campus. There's a single endpoint at the far end of campus that needs to have LAN-type speeds back to the DSLAM for a specific application. It's just this one endpoint that needs this. This endpoint has 3 or 4 separate copper runs to it.

Yes, the products people pointed out that enable this look very enticing. The Adtran one less so because it appears to only come in 28 port versions, and I can guess that the price would be >$1k. We'd only ever need 1-4 ports (for this one endpoint).

Ah, but you're assuming we don't want "a hack" :-) Toying around with free surplus linux boxen to achieve what a multiple-thousand $ solution can do is right up my alley!
For anyone on this list that may need to deal with buildings where new wiring is a problem (asbestos is a typical example), this is a solution for utilizing existing "telephone" wiring to build a network.
Yes, I can see the value there when multiple drops are required.
If you are looking for carrier grade, then Adtran also makes DSLAMs with Gig over copper DSL type solutions, but I assume you are looking for cheap.
Ya, replacing the DSLAM at this point is not viable.
Aside: all of this begs the question, how are they getting gig out of crap cabling? What are they doing, technically? Where's Shannon's law? If it was always possible, how come this site is using a crappy slow DLSAM at all? Why should anyone install CAT6 ever when their junky CAT3 can do Gb? Confused.
Thanks!
