I was thinking the same thing. They're a few years out of support, but
the Zhone 42xx IP DSLAM provides a 1Gbps ethernet uplink and 24 ADSL2+
DSL user ports per 1U chassis (stackable to achieve 192 ports total).
Wish they were available in AC for non-telco use.

You could pair these with a pfSense appliance (or an x86 PC running the
free software) to provide DHCP, DNS, etc - or use the built in pfSense
captive portal to provide additional authentication and accounting per
user. pfSense can provide NAT and FW if needed, or these features can be
disabled to use globally routable IP4/IP6 addresses.
As far as support goes, backup your pfsense and DLSAM configs when you
finish the project and the subscriber accounts and DSL modems could be
maintained by a local admin through the pfSense web interface with no
need to touch the DSLAMs or anything CLI.

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.
