A saturn can do 80Mph, but do you want to race a Porsche? If "handle" is what you are looking for, then buy the cheapest thing on the market, but MOST isps (hopefully yours and mine) care more about other such things. Imaging if your upstream provider connected you with a cheap box that could "handle" your T1? You'd be rather upset, I think. > >I'm not trying to bait anyone, by the way, just to elicit information. >My question, more precisely framed, is this: > >Suppose I have a FreeBSD box, appropriately configured for my needs, >and I want to interface it to a high-speed (well, up to T1) serial >line.

Anyone who thinks that 4 low-end T1 routers are as good as 1 high-end pentium with 4 T1 port hasnt done it before......the inefficiencies (such as collisions) caused by 4 devices vs 1 is enough to sour that equation all by itself. > >In the past, one argument for option (1) has been that it was considerably >cheaper.

A DDS csu is < $200 and T1 $350....the cost points are similar. And I'll take the external unit so I dont have to replace the whole router if I get a hit or a failure as well. > >So my question is: what are the best arguments in favor of option (1)? >Note that the question is not FreeBSD vs. no FreeBSD.
