SurfUP for Voice VideoValue Proposition (1)

• Voice, Video and Fax/Modem processing on the
  same DSP
• Supports a flexible usage model
• Dynamic balance between media types processing
• Single integration for support of all media types
• Eliminates Voice/Video synchronization issues
• Other solutions separate Voice Video processing
  (different DSPs/host) resulting in an unbalanced
  system.

21
SurfUP for Voice VideoValue 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 based on DSPs that do not have a direct
  IP network interface suffer from unnecessary
  delay and bottlenecks.

22
SurfUP for Voice VideoValue 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 Voice VideoValue Proposition (4)

• Support for various applications with the
  same HW/SW
• VoIP Video gateways
• Voice Video Messaging/CTI applications
• Lawful Interception (LI) applications
• Other vendors will have two separate platforms
  one optimized for Voice and the other optimized
  for Video.

24
SurfUP for Voice VideoValue Proposition (5)

• Streaming diagnostics for quick resolution
  of issues
• The release version can stream the diagnostics
  from problematic connections without affecting
  other connections
• Other vendors do not support streaming
  diagnostics because their DSPs do not have
  external memory for temporary storage of data.
