Components
• The Cisco 7200 Series VXR chassis also include a Multiservice Interchange (MIX), which supports switching of
DS0 time slots via MIX interconnects across the midplane to each port adapter slot.
• The midplane and the MIX also support distribution of clocking between channelized interfaces on the Cisco
7200 to support voice and other constant-bit-rate applications. The VXR midplane provides two full-duplex
8.192-Mbps TDM streams between each port adapter slot and the MIX, which is capable of switching DS0s on
all 12 8.192-Mbps streams. Each stream can support up to 128 DS0 channels.
• The MIX in the Cisco 7200VXR provides the ability to switch DS0 time slots between multichannel T1 and
E1 interfaces, much like TDM capabilities. This enables the Cisco 7200VXR to switch DS0 voice channels on a
T1/E1 interface on one port adapter to and from separate voice-processing port adapters. It also enables DS0s to
be switched through the Cisco 7200VXR without any processing, which is a requirement in certain voice
configurations.
