You don't.  At least you shouldn't.  T-1s are full duplex.  Traffic in 
one direction is independent of traffic in the other direction.  

If you really want to do this, you can use an arithmet operator (like a 
plus sign) in the .cfg file.  Thee resulting number won't be very meaningful.

Kind of like saying that if northbound traffic is flowing at 55MPH and 
southbound traffic is flowing at 35 MPH, traffic on the freeway is 
therefore 90 MPH.  It just isn't a number that's meaningful.
