• Endpoint: A Terminal, Gateway, or MCU
• Gatekeeper: Access control + a little bit more
• Gateway: Translation between two technologies
• IP: Internet Protocol
• MCU: (Multipoint Control Unit) Endpoint

Network Choices/ Paths
• This is a good one
• Chaos
• Bonus Tip: Watching McGyver reruns is
probably your best bet in resolving this one
MCU Access in Oklahoma
• OneNet Hub Sites - White Pine
• OSU- Accord
• Pioneer - Video Server
The reality is……
• H.323 has been deployed in Oklahoma and
you will see it.
• OneNet is pressing to move in this direction
• You need to know a little about it.
Integration into a Teaching
Environment
• This is a “biggie” but has been largely
ignored
• Utilization of content resources has been
largely ignored
• It needs to be more seamless than it is
Solutions are often
technology oriented and
not student and teacher
oriented.
Scenarios you may encounter
• An existing DL studio
• The “Roll About Cart”
