SurfUP for Voice & Video:Value Proposition (1)SurfUP for Voice & Video:Value 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.



Direct DSPnetwork 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.



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 don’t allow vendors to add value to the media processing sub-system. External memory is a must for providing an open platform.



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.



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.
