Overview of Cisco 3600 Series Routers
Cisco 3600 series routers are modular access routers with LAN and WAN connections that can be
configured by means of interchangeable modules and WAN interface cards. With over 70 modular
interface options, Cisco 3600 series routers provide solutions for data, voice, video, hybrid dial access,
Virtual Private Networks (VPNs), and multiprotocol data routing.
This chapter includes the following sections:
