The RPM-PRs are double-height service modules that provide integrated IP in an ATM platform, enabling services such as integrated Point-to-Point protocol (PPP).The RPM-PR provides an ATM interface to the switch and supports up to two port adapters, a four-port Ethernet (10BASE-T), and one-port Fast Ethernet (unshielded twisted pair (UTP), MMF). It has a QED RM7000 processor subsystem that provides over 350 kpps (kilo packets per second) of throughput for IP packet forwarding. It provides integrated IP in an ATM platform.The RPM-PR has an attached daughter card that contains the processing intelligence and contains the firmware that distinguishes the interface, such as OC-12c, OC-3c, T3, E3, and so forth.
