T1 will support multiple subinterfaces on our Cisco 7200 Router. We have a hub and spoke topology with 56 circuits at the edge with a CIR of 28k. How many possible number of subinterfaces can I have or what is the formula for figuring this out? I would like to determine the amount possible with a single T1 and multiple remote 56k edge devices. The pvc is built with a cir of 28k. Thanks in advance for helping out!!
I have this problem too.
