1 C H A P T E R Cisco 10008 Router Overview The Cisco 10008 router 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. This chapter contains the following sections: • Cisco 10008 Router Features, page 1-2 • Cisco 10008 Router Software, page 1-3 • Cisco 10008 Router Hardware Description, page 1-3 Note The illustrations in this guide depict the original Cisco 10008 chassis. Your chassis may look slightly different, but it is functionally the same. The Cisco 10008 router is designed to meet and exceed the most stringent ISP requirements for product availability and reliability. Its features include: • Redundant blowers • Redundant power (AC or DC) • Redundant PREs • Pairs of Synchronous Optical Network (SONET) interfaces which can be configured for redundancy using SONET 1+1 Automatic Protection Switching (APS) • All line cards, Power Entry Modules (PEMs), and blowers can be hot-swapped without powering down the chassis OL-0659-13 Cisco 10008 Router Hardware Installation Guide 1-1
