Yes, it can, not sales talk but tested on labs. I think there are some
tests online from Current Analysis. Anyway see my concerns below about
how many subscribers I would put in any BNG of any vendor.

I'd be concerned too. How much is in percentage of your total
subscribers those 144K? How much averge bandwidth do you want to give
them with just one box? I don't think is an scalability problem but a
design one. I wouldn't have more than 64K, 96K per box if those
represent a 20-25% of the total subscribers or more, because if that
BNG goes down I would have that percentage of subscribers down, etc.

A different scenario would be to have two boxes, both as active and
they are backup of each other. So let's say you have 64K per box, then
if one fails you can work with the other supporting 128K but that
should be a temporary state while repairing/replacing/rebooting the
other one.

Same thing with this new SSR, I wouldn't put more than half a million
subscribers in one box just because it supports them.

No, all I have seen was no more than 96K per box.
