Cisco 10008 - Modular expansion base - Product Details
The Cisco 10008 Edge Services Router (ESR) is a high capacity Layer 3 router optimized to support selected Cisco IOS software services at wire speed performance on thousands of DS1/T1 connections. Designed primarily for use in a Telco central office environment, it provides interfaces that connect to large numbers of subscribers using low-speed circuits, and then funnels all of that subscriber traffic into a small number of high-speed trunk interfaces. The chassis has eight line card slots and two slots for Performance Routing Engine (PRE) modules.
