possible problem #1: "N" is "now" but that is *not* when you got the numbers. There will be a small difference each time. This difference will vary from poll to poll. This will cause jitter. If this is the case, the next (or previous) interval would have a similar error but in the opposite direction. If you have multiple "too large" intervals in a row, this means jitter is not your problem. > The maximum rate on an OC3 should be 155.52Mbits.

However, 'rrdtool dump possible problem #2: 155.52 Mbps is rounded, is payload etc. Make sure you are monitoring what you think you're monitoring. Perhaps you're also seeing the framing and signaling?
