If this is telco provided dry pair then the distance is probably longer
than 6 miles as the endpoints are probably tied together through a telco
CO.

I have not heard of any equipment which will work over a 6 mile pair any
faster than you're getting with T1.

You might consider setting up wireless repeaters to bridge where there is
no direct LOS. Look at what the hamwan guys have done. http://hamwan.org/
