I understand this (I think :), but I've a theoretical question.
Assuming the following:
T1 T1 T1 T1 ...

Just how many T1->Router->Etherswitch connections can be run through
point A (a single 10Mb ethernet) before things become unbearable (real
world here, I think I can do the math :-)? Should I look at a 100Mb
ethernet port on the 4500 instead of the dual 10M ethernet option?
I'm working on a project for a small NAP, and this concerns me. I'd
