Description Nortel Networks' new high-performance ILIs combine the new FRE4-PPC with new 10/100 Mbps Ethernet Link Modules. The FRE4-PPC provides a significant performance increase. It is optimized for the high data rates achieved on multiple 100 Mbps LAN interfaces. The FRE4-PPC incorporates patentable technology to achieve this goal. The FRE4-PPC uses a 266 megahertz (MHz) PPC750 microprocessor. The FRE4-PPC can be configured with local memory options of 32, 64, or 128 MB. The FRE4-PPC and associated ILIs are supported in Nortel Networks' Routing Services (BayRS) v13.20 software, which is available with either 16 MB or 32 MB Flash cards for the BN router.
