• Wide variety of protocols
• Cost reduction
• Evolutionary migration
• Stability of Manufacturer/Product
• How can we meet these requirements?

4
A Common Application Theme

• Eliminating or reducing the number of T1 leased
  lines between sites for multi-location
  enterprises, governmental/public organizations
  and Service Providers by
• Transporting T1/T3 voice circuits (TDM) across
  existing Ethernet/IP connections (Circuit
  Emulation or pseudo-wires)
• Compressing voice traffic to dramatically reduce
  bandwidth requirements (Optimized Voice
  Transmission)
• Transporting voice and data across point-to-point
  wireless links

5
TDM Voice Data Convergence

• What is it?
• Transporting traditional (TDM) and analog voice
  circuits such as T1, FXS, FXO or EM from PBXs
• Across packet networks such as IP, Ethernet, PPP
  or MPLS
• While maintaining 100 transparency for the voice
  endpoints (TDM circuit emulation)

• Benefits
• Use efficient IP/Ethernet transport without
  needing to convert existing voice equipment to
  native VoIP
• Converge voice and data onto a common IP/Ethernet
  infrastructure
• Less costly, less risky, evolutionary path toward
  VoIP

• Target Markets
• Universities with campus environments
• School districts
• Enterprises with campus or metro area networks
• Metro Ethernet service providers delivering T1
  replacements

City of Burlington, VT
Challenge - To reduce expenses by replacing
costly Centrex services with a municipality-owned
T1 voice over fiber distribution solution. To
extend voice over fiber to remote sites requiring
one or more T1 lines without compromising voice
quality or functionality

PetroCom Case Study

• Challenge To cost-effectively deliver PRI and
  EM voice, along with low and high speed data,
  between British Petroleums corporate
  headquarters and major offshore oil platforms.

• Solution RADs Vmux-2100 and Megaplex-2100
  provide all of the voice and data interfaces
  required, and the Vmux-2100 compresses the voice
  traffic so it is efficiently carried between
  sites over an IP satellite link. The RADview NMS
  and RADcare Service Program help PetroCom enforce
  its SLAs.

The Vmux reduces the bandwidth requirement and
minimizes the effects of delay and echo inherent
in satellite circuits. Ken Wright Chief
Operating Officer Petrocom

PetroCom Case Study

• BP requires 99 system uptime and 30-second
  restoration in the event of a failure. The
  RADview Network Management System is a critical
  component that enables PetroCom to meet these
  requirements.
• PetroCom intends to replicate this solution on
  two additional platforms that BP is planning to
  deploy in the near future, as well as at other
  existing BP installations around the globe.
• The Vmux-2100s 161 voice compression saves BP
  tens of thousands of dollars each year in
  satellite connectivity costs.
