Might want to look for old Zhone ip bitstorm dslams.  There should be a bunch on the used market.  They do all of the ATM conversions internally so you just need to feed them with ethernet.

They don't have a large budget and although I'm yet to get prices on adtran's (understandable, holidays 'n all) I doubt it will fit within their budget, it's looking more like getting a few planet dslams and configuring a linux box as the bng, been 10 years since I've had to do that kind of setup, memories hazy, but I know it worked, and well, so thanks to all for suggestions but the adtrans and nokias are not for those on shoe string budgets, which wouldnt even allow me to include an asr1k for the bng, and although it would allow for, I'd rather not grab an ebay 7200/7300 :)

Is there a logical way to distribute the termination?  You might be able
to get better performance (not that you perhaps care, in this case) at
minimal additional cost if you can do building-local termination of each
customer circuit and then backhaul on e.g. bonded VDSL2 or G.FAST over
shorter distances (perhaps hopping building to building).

I'm assuming there's no data grade copper or fiber if there's no coax.
Obviously if you've got those, distributed termination makes even more
sense.

If you do want a centralized solution, an Adtran TA5006 (the small
chassis) with 6x 48 port VDSL2 combo modules (with or without vectoring,
depending on your needs) would do the job (though it fills the chassis
and doesn't allow for expansion, so the full-size TA5000 may be
desirable).  I've played (and am playing with) the same system but with
GPON termination and have been happy with it so far.
