if that's for more than 5-10 minutes at a time your way overloaded.

a t1 is bidirectional.
you don't need more outbound, but you need more inbound (you can do 100% in
both directions in theory)

if it was my network i would have pulled another t1 in when the load was
hitting over 80% for more than 20 minutes.
