4.3.3CIR (Committed Information Rate)

The carrier programs virtual circuits into the network between your sites and charges you for a specific level of service called the committed information rate (CIR). The CIR is basically a guarantee that the carrier will always have that bandwidth available. The CIR limit for the Prestige is 8Mbps. The sum of CIRs from all channels in a line cannot exceed 8Mbps due to the processing limit of the P1600 CPU.

4.3.4EIR (Excess Information Rate)

This is the burst capability of the connection, i.e., the maximum allowable data transfer rate. EIR must be greater than or equal to the CIR.
