generation Cisco IP/VC 3540 MCU.The 3544 Chassis provides power load balancing
and redundancy, status LEDs, and cooling fans, and can accommodate up
to four IP/VC 3540 MCU cards on a cPCI bus.The first MCU in the chassis
must be a system module, which provides management functions for modules
installed in the remaining slots. An application server module is also available,
which is a Windows NT system installed with Data Collaboration Server (DCS).
The T.120 based IP/VC DCS allows users to present slides, use a whiteboards
