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 VXR routers support a high-speed network services engine (NSE) as well as the high-speed network processing engine. The Cisco 7206VXR supports multiprotocol, multimedia routing and bridging with a wide variety of protocols and port adapter combinations available for 7200 series routers. In addition, the Cisco 7206VXR midplane provides increased support for multiple high-bandwidth port adapters.
