Internet, WAN, IVC & More

Services UEN provides to it’s stakeholders.

  • Internet access and research network access via the Front-Range Gigapop, Nat’l Lambda Rail, & I2
  • Backbone and WAN connectivity for all higher education, school district offices, secondary schools, and many city & county libraries.
  • Statewide IVC network connecting over 400 higher education and public education classrooms.
  • KUEN - Telecourses
  • Web Conferencing with Wimba (newest service)
  • Emedia
uen s interactive video conferencing network ivc the technical side
UEN’s Interactive Video Conferencing Network (IVC) The Technical Side
  • 400+ higher education & public education classrooms throughout Utah
  • 320 bridge ports currently available - UEN recently transitioned from a distributed bridging platform consisting of seven 48 port Radvision ViaIP 400 Multipoint-Control-Units (MCU) to eight 40 port Tandberg-Codian MCUs. Six of the MCUs are located in Salt Lake City, a seventh operates in southeastern, Utah and the eighth is located in eastern, Utah. Regional MCUs allow regional events to continue in the event of a backbone outage.
  • Two Codian IPVCRs enabling UEN to record up to 20 conferences/classes at a time.
  • 1 Tandberg Border Controller for firewall transversal.
  • UEN launches over 500 events per week.
uen interactive video conferencing ivc the people
UEN Interactive Video Conferencing (IVC) The People
  • Two Video Operations Centers providing seamless IVC support from 5:00 AM to 11:00 PM Monday thru Saturday.
  • UEN Field Operations and Network Operations Center support
  • Distance Education Specialists/Training
  • UEN Scheduling – Coordinates the scheduling of events statewide.
    • Work directly with higher education and public education counterparts coordinating all IVC events.
ivc s solid network foundation
IVC’s Solid Network Foundation
  • One of the key elements to UEN’s successful implementation and support of it’s IVC network is the Wide Area Network (WAN).
    • Gigabit Ethernet backbone with a ring topology in key regions of the state.
    • Gigabit Ethernet to all higher education and most public schools. With a minimum of a dedicated T1 per IVC classroom if broadband is not available.
    • Close coordination with district and campus network staff
support challenges for video
Support Challenges For Video
  • Campus and District Firewalls
    • Open required ports (Set range of ports)
    • Implement secure video VLAN/Firewall bypass
    • Firewall transversal appliance
      • Last resort – Solution works best when implemented to support vendor specific end points. To support all h.323 end points additional appliances may be required.
  • A scheduling and management application that meets the performance requirements of a large enterprise service provider.
firewall options
Firewall Options

Best overall solution for UEN is the implementation of a secure video VLAN/Firewall Bypass – not susceptible to changes to firewall configuration

High School

Video VLAN


School District and campus inside and outside switch and firewall


Open select set of ports

to support H.323 video

transition to tandberg codian mcu and tandberg management suite
Transition to Tandberg-Codian MCU and Tandberg Management Suite
  • Tandberg-Codian
    • N+1 MCU configuration
    • Load balanced management servers
    • Redundancy wherever possible
    • Target of 99.99% Reliability
    • Scaleable – Enterprise solution
    • MCU supports transparent cascading
      • UEN classes average 8 to 12 sites per event but some colleges will schedule classes with over 20 sites which often requires cascading.
uen video conferencing requirements
UEN Video Conferencing Requirements
  • H.264 – MPEG 4 Compression
  • H.239 – Duo Video/Dual Stream
  • 16:9 Display w/ split screen for Duo Video when possible
  • Multiple view options including Continuous Presence (Hollywood Square view)
  • E.164 Alias – (4 digit dial plan)
  • Gatekeeper Registration
site requirements certification
Site Requirements & Certification
  • Classroom size and configuration
    • Origination Room
    • Receive/Simple Room
  • Lighting and adequate window coverings
  • Projector or monitor must support 16:9 display and 720P resolution
  • End point must have dedicated network connection to a managed network switch
  • Sufficient dedicated bandwidth – (T1 minimum)
  • Endpoint must test with zero network errors, packet loss, and minimal jitter.
  • Demonstrated dial-in and dial-out through firewall
  • VOIP - Telephone for Video Operations Center Support
  • Gatekeeper Registration
instructor and facilitator training
