Cisco CISCO7204VXR= Wired Router Networking

The Cisco 7200 VXR routers are the multiservice members of the Cisco 7200 series routers. The Cisco 7200 VXR routers are designed to support gigabit capabilities and to improve data, voice, and video integration in both service provider and enterprise environments. The Cisco 7200 VXR routers incorporate an integrated Multiservice Interchange (MIX) capability to support future voice applications. MIX interconnections on the midplane provide the ability to switch DS-0 time slots between multichannel T1 or E1 interfaces, much like a digital cross-connect or an add-drop multiplexer. This feature enables the Cisco 7200 VXR routers to switch DS-0 voice channels on a T1 or E1 interface from one voice processing port adapter to another voice processing port adapter. It also enables DS-0s to be switched through the Cisco 7200 VXR routers without any processing, a requirement in certain voice configurations.
The Cisco 7200 Series offer the choice of two chassis for flexible deployment: Cisco 7204VXR with four horizontal port adaptor slots, and the Cisco 7206VXR with 6 horizontal port adaptor slots. Both chassis provide up to 1Gbps backplane bandwidth, and include integrated multiservice interchange (MIX) functionality.
