Appendix A. Rate Queue Information for IRIS ATM-OC3c HIO Mezzanine Hardware

To configure the transmission rate queues on the IRIS ATM-OC3c HIO mezzanine board (on CHALLENGE and Onyx systems only), use the codes from the left column (Code) of Table A-1. The right column (ATM Cells per Second) of the table summarizes the rate (in number of ATM cells per second) that each code configures.

One ATM cell consists of 53 bytes: 48 bytes of user payload and 5 bytes of ATM overhead. If you are interested in a different rate metric than cells per second, the following formulas can be used to make the conversion. The cells-per-second value in each formula is a value from the ATM Cells per Second column in Table A-1.
