What is TDMoIP?

• Protocol for extending circuits over IP networks
• Transparent to protocols and signaling
• Simpler and less expensive than VoIP and ATM
• Supports legacy PBX - including proprietary
  features
• Beats VoIP with lower latency and higher quality
  voice
• Good for voice, data and video over IP
• Suitable for Enterprise and Carrier applications

How Does TDMoIP Work?

IP
TDMoIP Gateway
T1/E1 or T3/E3Frame
IP/ Ethernet
IP/ Ethernet

• The synchronous bit stream is chopped into
  packets
• IP headers are added
• Packets are forwarded to destination over the IP
  network
• At destination, the original bit stream is
  reconstructed by removing IP headers,
  concatenating the packets, and regenerating the
  clock
• This technology is called TDMoIP

What is a TDMoIP Gateway?

• Towards User
• Emulates a CSU/DSU
• T1, E1, T3 or E3
• Transparent to protocol signaling

• Towards Network
• Emulates an IP host
• 10/100BaseT
• Configurable QoS

TDMoIP vs. ATM

• TDMoIP provides similar benefits to ATM
• low end-to-end delay
• maintains integrity of framed or unframed T1/E1
• In contrast to ATM, TDMoIP
• is simpler and less expensive
• has configurable packet size for optimizing
  overhead/delay trade off
• is carried over ubiquitous IP and Ethernet
  networks

7
TDMoIP vs. VoIP

• TDMoIP and VoIP both offer convergence over IP
• In contrast to VoIP, TDMoIP
• is transparent to protocols and signaling
• is simpler and less expensive
• provides higher quality voice with much lower
  latency
• supports installed PBXs with no loss of
  functionality
• supports all modem and fax rates
• Supports sync and async protocols over IP
  (including Frame Relay, ATM, ISDN, SS7, SNA,
  X.25)
• maintains integrity of framed and unframed T1/E1
  circuits

TDMoIP and VoIP
Have same goals - convergence, ...but a
few critical differences

• TDMoIP (Telephony over IP)
• Simple evolutionary
• uses standard, mature, and well known protocols
  T1, IP
• low cost of ownership
• Maintain installed PBXs
• significant cost savings
• little disruption to business
• No loss of PBX functionality
• Low delay
• transparent to signaling and protocols
• Configurable packet size
• low delay
• configurable overhead
• Data voice circuit extension
• DS0 level bundling X-connect

• VoIP (IP Telephony)
• Complex revolutionary
• new evolving protocols such as H.323, MGCP, and
  SIP
• complexity requires retraining IT
• Fork lift upgrade (reinvent the telephone switch)
• compatibility issues
• Limited today, new features possible
• Long call setup times
• translation between signaling formats (SS7,
  ISDN,..)
• Packets depend on codec samples
• delays as sample is recorded
• overhead on each voice session
• Primarily voice
• Voice switching per call

TDMoIP Benefits for Enterprise

• Addresses business concerns with evolutionary
  rather than revolution solutions
• Migration path to IP without compromising current
  telephony features (Supports all PBX features and
  signaling transparently)
• Low cost deployment with quick installation IP
  is simple (especially over GbE), it reduces costs
  and provisioning times
• Protects investment in legacy equipment with TDM,
  T1/E1 and T3/E3 interfaces (from PBXs to SCADA
  systems)
• Enables expansion with scalable Ethernet-based
  solutions
• Additional bandwidth when T1/E1 and T3/E3 is
  bundled onto Ethernet, rather than vice versa
• Reduces equipment needs by grooming T1/E1s with
  DS0 granularity

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 Blue Ridge Communications

• RAD's TDMoIP solution saved us money, improved
  overall
• voice quality, and allowed our remote offices to
  enjoy the
• full features of the central site PBX. There was
  simply no
• other solution that could have offered us so many
  benefits.Barry Fink, PC Network Technician,
  Blue Ridge Communications
• This simple TDMoIP solution saved Blue Ridge
  from having to
• maintain a separate TDM-based network and incur
  the costs of
• TDM switching equipment at each office. There was
  no other
• cost other than having to buy the IPmux for each
  end.

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

23
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

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 Rockefeller Group

• Sept 11 WTC attack disrupted underground fiber
  optic cables
• Companies were left without voice, data and
  Internet services
• Relocated employees overloaded existing voice
  lines
• Solution
• Rockefeller Group Telecommunications Services
  (RGTS) deployed free space optics to connect
  buildings
• RGTS installed TDMoIP gateways to deliver T1
  circuits across the Ethernet/Laser transport

27
Case Study Rockefeller Group
With TDMoIP, RGTS can extend voice services from
the traditional voice switches to the customers
PBXs without the expense and complexity of
upgrading to VoIP or leasing costly T1
lines. Chris Abrams, Consulting Engineer at
RGTS
28
Case Study PEND Oreille PUD

• Pend Oreille PUD uses extra capacity in its
  underutilized fiber network to provide 10Mbps
  Ethernet connections for Internet Access and
  LAN-to-LAN services to the rural district it
  serves.
• Goals
• To also deliver revenue generating T1 private
  line services to enterprises
• To act as a carriers carrier by providing T1
  leased lines to the ILEC
• Solution
• RADs TDMoIP gateways emulate T1 circuits for
  voice, video or data connections over the
  underlying Ethernet infrastructure
• Benefits
• Ethernet provides simple scalability, low cost
  and high bandwidth
• RADs IPmux adds TDM capability without the
  expense and limitations of traditional SONET and
  DACS equipment
• Supports all legacy services transparently

Case Study PEND Oreille PUD

• RADs IPmux is performing well above
  expectations. I am especially impressed with its
  remote provisioning capabilities, which are
  important to us since the customers site is so
  far away.
• The IPmux has essentially helped us to
  bridge the digital divide in a rural area where
  this was previously not possible.

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

32
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

33
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

34
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
