I'm having latency/congestion problems with my Level 3 circuit where I have a 200 MB CIR. Level 3 says we were going above our CIR even though my interfaces usually showed somewhere near 120 Mbps outbound (to Level 3). I asked the question of whether my 200 MB was 200 MB up and 200 MB down or whether it was 200 MB total. They said it was 200 MB up and 200 MB down. ok - great.
But when I brought up the option to upgrade my service they mentioned that they are only provisioned at my location with four STS1 circuits and that it would take time to expand their services there. Now, from what I can tell four STS1's have a BW of 51.84 Mbps each. And that is total - not 51 MB up and 51 MB down.
Can anyone tell me if I'm wrong here? If I have a T1 for a circuit, then I am getting 1.54 MB total. Are STS1 circuits somehow different?
