Releases 2 - 5.2, Part Number OL-4545-01, Rev. H0, May 2006
Chapter 2 Illustrated Card List for MGX Switches and the MGX 8880 Media Gateway
Front Cards
The following module configurations are supported for the PXM45:
• Standalone.
• Card set redundancy (Y-cable).
Note For module configuration information, refer to Chapter 4, “Planning for Card Redundancy, Line
Redundancy, and Bulk Distribution”.
RPM-PR
Supported models: MGX 8850 (PXM1E/PXM45), MGX 8850/B (PXM1E/PXM45), MGX 8950, MGX 8830, MGX 8830/B, MGX 8880
The RPM-PR is a double-height service module that provides integrated IP on 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 a one-port Fast Ethernet (unshielded twisted pair [UTP], MMF)
• Has a QED RM7000 processor subsystem that provides over 350 kilo packets per second (kpps) of
throughput for IP packet forwarding
• Provides integrated IP in an ATM platform
• Has an attached daughter card that contains the processing intelligence and contains the firmware
that determines the interface type (OC-3c, OC-12c, T3, E3, and so forth)
When the RPM-PR is combined with one or two back cards, a card set is created. Table 2-26 provides
information about each RPM-PR card, interface, and corresponding back card.
