Ok, I heard, that Annex should be fine, too.

Too bad, _this_ would be interesting for me, since my company
is about to buy such things. Our ISP described those Portmasters
as the best you can get, because of port speed and robustness.

It's perhaps a question of service contracts or you really need one
in stock... On the other hand ... how many FreeBSD Boxes do you need,
if you want to handle 50 modem lines ? Ithink this yould be more expensive.
I think two Portmaster with 30 lines aren't that bad .. if one fails,
you still have the other ...
