All Committed Information Rate (CIR) and Maximum Information Rate (MIR) units are in Kilobits Per Second (kbps).

When planning, one should plan for the CIR. MIR throughput typically only happens over a few seconds and should generally not be expected to last for very long.

Since most people tend to think in terms of MegaBytes, note that one MegaByte is 8192 kilobits.
