Chasing some info, does dlink still sell DAS4672 - 672 port adsl2+ dslams?

after simple IP based  units with pppoe pass through.
We could buy a bunch of planet 48 ports, which we used before, but we
hoping someone still puts out high capacity (320 plus port) units with
inbuilt pots splitters

thanks
