The "newer" replacement for the 42xx series was the bitstorm
(Bitstorm-RP2-152-AC), and they came in AC as well and 48 ports -- in a 1.5 U I
think .

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.
