maximum thruput res cable router

A theoretical question for the experts here.
What would the maximum throughput for a resdiential (i.e.
not a business connection ) for a cable router downloading one file from an unlimited speed (single direct T1 line) be ??

 

No difference in business vs. home. A full T1 transfers data at 1.544 Mbps symmetrically. If you have fractional T1, it will depend on how much bandwidth you have bought.

 

maybe I did not explain myself

Newt,
what I am asking is what is the maximum thruput rate of a
home cable broadband connection
soon I will be fluent in English

 

Depends completely on what speed you have paid for. Also, upload is usually slower than download but again, because that is what you pay for.

And unless you have some sort of good guarentee from them, you could still be in for a rude shock because the cable broadband (as opposed to DSL or sat.) is like a large office network. The more folks using it at once, the slower everyone runs below the maximum rated speed of the network.

And Canadian cable is slower in winter than summer because the cold make the electrons shiver which isn't too efficient. (well, the first two paragraphs are mostly true anyway).
