Both Ports A & B examine data from the ATM Interface. For troubleshooting purposes you may at some point need to do a data dump. Use this sub-menu to instigate the procedure, but first you have to make the proper connections and run preliminary tests before the data dump can occur. For now we will provide a brief overview of these menus. For information on a data dump procedure see Appendix A.
