SurfUP for Transcoding Value Proposition (1)

• Voice, Video and fax/modem processing on the same
  DSP
• Supports a flexible usage model
• Always balance between voice and video processing
• One integration for support of all media types
• Eliminates voice/video synchronization issues
• Other solutions separate Voice Video
  processing (different DSPs/host) causing system
  to be unbalanced.

21
SurfUP for Transcoding Value Proposition (2)

• Direct DSP??network interface for lowest possible
  delay
• DSPs connected to Ethernet eliminate the need for
  an aggregation unit that causes excessive delay
• Solutions with DSPs that do not have direct IP
  network interface suffer from unnecessary delay
  and bottlenecks.

22
SurfUP for Transcoding Value Proposition (3)

• Open Platform
• Vendors are able to add SW modules to the DSP
  code, in order to create a competitive advantage,
  without the need to recompile the DSP or host
  interface code
• Integration of new Voice and Video standards
  takes no more than a few days
• Closed system solutions dont allow vendors to
  add value to the media processing sub-system.
  External memory is a must for providing an open
  platform.

23
SurfUP for Transcoding Value Proposition (4)

• Support for various applications with the same
  HW/SW
• VOIP Video gateways
• Voice Video Messaging/CTI application
• Lawful Interception (LI) applications
• Possible ONLY when Voice Video run on the same
  DSP.

24
SurfUP for Transcoding Value Proposition (5)

• Streaming diagnostics for quick resolutions of
  issues
• The release version can stream the diagnostics
  from problematic connections without affecting
  other connections.
• Control is per channel/call/DSP
• Solutions without external memory cannot include
  diagnostics in the release version.
