Video Conferencing

Multipoint Conferencing Server (MCS) or Multipoint Conferencing Unit (MCU)

An MCS or MCU is a hardware or software H.323 device that allows multiple videoconferencing (or audio or data) users to connect together. Without an MCS typically only point-to-point conferences can take place. Commonly supports voice activated switching, where whoever is talking is broadcast to all users, but new systems support "Hollywood squares", where multiple windows show each participant.

DTI and DOE currently possess the only units accessible to K12 that can allow for a multipoint meeting. DOE's full room, portable system and the DTI loaner system can handle up to 4 endpoints. The units themselves occupy one of those endpoints. All locations must be preloaded into the main system that then initiates all calls to the other sites involved. DTI also has a stationary unit in one of their conference rooms which has very limited availability (it handles up to 6 endpoints). Other State agencies may have video conferencing systems but most are unavailable for loan due to usage.

Through our membership in MAGPI (our Internet2 consortium), we have access to an MCU (up to 7 endpoints). For events larger than 7 endpoints, we use the Internet2 Commons. They can handle up to 40 endpoints. If you need to go larger, we can work with the Internet2 Commons to cascade MCUs. For more information about this service, visit: http://www.magpi.net/internet2commons.html. These video conferences require making a reservation through MAGPI for the meeting and setting up testing for all sites involved. Contact Randy Reynolds or Dan Farley for more information on multipoint meetings.
