The upload cap bothers me, yes, mainly due to the glaringly obvious
potential for a DoS attack. If your line can take 4.4mbit worth of
packets, but can only reply to 1.1mbit worth of them...isn't there a
slight problem?
My solution on a 1.2/1.1 line at work was to cap the download rate, since
the line is used for servers, not web browsing. The Cisco 67x allows that
quite nicely. I dropped it down to 1.0/1.1, and it works fine.
Anyway, of course it's not synchronous. It's Asynchronous DSL. :)
Just thought I'd put my $0.01 in. (Hey, give me a break, I'm short on
cash.)
