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 AAL1
  (CES)
• 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

6
TDMoIP vs. VoIP

• TDMoIP and VoIP both offer convergence over IP
• In contrast to VoIP, TDMoIP
• Is for TDM transport over IP whereas VoIP is a
  voice switching application
• 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, GR303,
  SNA, X.25)
• maintains integrity of framed and unframed T1/E1
  circuits

  SIP
• complexity requires retraining IT
• Fork lift upgrade (reinvents telephony)
• Expensive upgrades replacements
• compatibility issues
• Translates between signaling formats
• Limited support for existing PBX features
• Long call setup times
• Packets depend on codec samples
• delays as sample is recorded
• overhead on each voice session
• Primarily voice
• Voice switching per call
