Cisco Interface Processor - Expansion module - Gigabit EN - plug-in module

The Gigabit Ethernet Interface Processor (GEIP) integrates a VIP technology-based intelligent processor with a media specific solution, providing a complete, single-slot solution for Gigabit Ethernet connectivity in the Cisco 7500 series router. The GEIP provides moderate performance capabilities, appropriate for campus, enterprise edge and WAN aggregation applications. When used on the campus, the Cisco 7500 series router with the GEIP connects the enterprise WAN and legacy LANs, such as FDDI or Token Ring, to the Gigabit Ethernet campus backbone. At the enterprise edge, the Cisco 7500 with GEIP provides WAN to campus backbone connectivity. When the Cisco 7500 series router is used for WAN aggregation, the GEIP provides intra-pop connectivity between the Cisco 7500 series router and high-speed WAN core devices, such as the Cisco 12000 series router.
