TDMoIP Gateway solutions for the Educational
Market

• Education facilities ranging from schools and
  libraries to universities are facing
  exponentially increasing demand for bandwidth. In
  response to this demand there is increasingly a
  shift towards Ethernet and IP networks
• TDMoIP Gateways complement the campus or
  Educational Metro Area Network (EMAN) by
  transporting legacy voice, video and data over
  Ethernet infrastructure.
• This solution supports modems and faxes at full
  speed and H.320/H.324 video, ATM, Frame Relay and
  ISDN over IP.
• Since the integrity of the T1/E1 circuit is fully
  maintained, the school doesnt lose important
  features such as caller ID and enhanced 911
  emergency services

Case Study Elizabeth Forward School District
T1/Voice over Gigabit Ethernet Infrastructure

• Goals
• Simplify network by eliminating complex ATM
  infrastructure
• Increase bandwidth for video streaming,
  conferencing, surveillance systems, LAN services
  and Internet access
• Reduce costs by eliminating the separate T1 lines
  (converging voice traffic over data network)
• Solution
• Simplify network and increase bandwidth by
  replacing ATM with GbE
• Replace T1 links with T1/voice over IP solution
• initially considered upgrading PBXs to support
  VoIP, but this was very expensive and compromised
  features
• Selected RADs TDMoIP gateways for transparent
  circuit extension over IP

12
Case Study Elizabeth Forward School District
T1/Voice over Gigabit Ethernet Infrastructure

• Benefits
• Simple GbE and TDMoIP solution is resilient and
  easy to manage
• Lowest cost solution (TDMoIP cost 1/12th that of
  VoIP)
• TDMoIP supports all existing PBX features
  transparently
• Simplified networking for teachers and students
• Easily expandable to planned new district schools

Case Study Elizabeth Forward School District
Voice over Gigabit Ethernet Infrastructure

• The IPmux is very straight forward and provides
  T1 service quality across the board.
• Because our computer systems are now easier to
  use and more efficient, teachers are not as
  hesitant to integrate technology into their
  curriculum. Instead of focusing on how to keep
  the systems running, we can concentrate on the
  students while taking full advantage of
  technology to enhance their education.

Case Study Spokane E-MAN

• First Educational Metro Area Network running
  voice and data to over 50 sites using GbE
• Goals
• High-speed filtered Internet
• Shared data - such as library information
• Voice and video conferencing between institutions
  
• Replace expensive Centrex and Frame Relay lines

16
Case Study Spokane E-MAN

• Initially implemented VoIP but there were
  problems
• Complex to install and maintain
• Voice quality was compromised by delay, echo, and
  compression
• PBX interface, feature transparency, etc.
• VoIP replaced with RADs TDMoIP gateway because
• TDMoIP provides far superior voice quality with
  much simpler installation at lt 30 of the VoIP
  prices
• Transparent support for all PBX features
  including V.90 modem, V.34 fax, 911 services

Integrator Feedback
Spokane School District No. 81 E-MAN

• We had a difficult time interfacing the VoIP
  gateways with the PBXs, but now with RADs IPmux
  we can deliver a solution that meets the
  customers expectations for voice quality and low
  delay, and at a fraction of the cost of VoIP

Case Study University of South Florida

• Campus Network with Video Conferencing
• GbE backbone connecting over 80 buildings
• Switched Fast Ethernet within buildings
• Video conferencing system with ISDN PRI links
  (H.320)
• T1 circuits statically provisioned between
  lecture halls for video conferencing

20
Case Study University of South Florida

• Problem
• Video conferencing between lecture halls required
  dedicated T1 circuit to be provisioned (to
  support PRI ISDN)
• Couldnt easily get T1s to the building (without
  considerable expense)
• Lack of mobility to satisfy last minute moves and
  changes
• Solution
• Create virtual T1 circuits between lecture halls
  using TDMoIP
• Achieves mobility simply plug TDMoIP gateways
  into campus LAN for instantaneous T1 circuits
  between lecture halls

21
Virtual T1s between Lecture Halls

• Video conferencing unit (in a remote building) is
  hooked to a 320/323 bridge across campus which is
  used to allow classes between the remote building
  and many other conferencing locations on campus

22
Integrator Feedback
University of South Florida

• The RAD IPmux solution provides USF with a
  cost-effective and fully functional way to
  rapidly extend T1s to remote locations over our
  existing LAN/WAN infrastructure. The mobility and
  flexibility of this solution has been
  invaluable. Joe Rogers Network

TDMoIP Benefits for Educational Market

• Protects investment in legacy equipment with LAN,
  TDM, T1/E1 and T3/E3 interfaces (from PBXs to
  Video to Alarm systems)
• Addresses educational concerns with simple
  evolutionary, rather than revolution solutions
  for teachers and students
• Migration path to IP without compromising current
  telephony features (Supports all PBX features and
  signaling transparently)
• Low cost deployment with quick installation
  TDMoIP is simple to install. It reduces costs and
  provisioning times
• Enables expansion with scalable Ethernet-based
  solutions
• Additional bandwidth when T1/E1 and T3/E3 is
  bundled onto Ethernet, rather than vice versa.
