If you do not route IP traffic over the T1 then there is no way anyone 
can upload or download.

Asterisk doesn't deal with IP data traffic (beyond the voice-related 
traffic). It's not a router. Cards such as the T100P have the ability to 
split data DS0 off of a channelized T1, or a PRI, but again, that's 
something that has nothing to do with Asterisk.

In the first case you are plugging a T1 into the back of Asterisk. I am 
assuming, since you did not specify, that it's a channelized T1 and the 
channels are provisioned for voice. Where does the router come into play 
that you mentioned?

In the second case you can use Linux itself as a router if you want. If 
you don't want, there are plenty of hardware options such as a VINA 
Integrator that work just fine in handling the dual traffic on a 
channelized T1. You can pick those up off of eBay for about $50 each, 
and they route IP and do firewalling and have T1-to-analog ports and 
everything, in a 1U package.
