asterisk users - Nov 2004 - Measuring Bandwidth on T1 into *

Here is our scenario:
  Company A is looking for a better VoIP/Internet solution. We approach and
say, "We will sell you 1 T1 for Voice only for XXX dollars per month."
They
agree. We install a router and the T1 at their location and plug the T1
directly into Asterisk. Lets say they've got a hot-shot-punk kid working
there and he hooks his laptop to the Ethernet port on the back of the
router. Will he be able to start downloading/uploading on that bandwidth
even though its hooked directly to the Asterisk server? If so, how can I
prevent the bandwidth usage but still allow VoIP calls?

 Switch it around..

  Company B is the same, however we will sell 1 T1 for voice AND data (at a
different price). How do I setup Asterisk to handle both?

Thanks,
Matthew

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.
