Whitepaper: From Prototype through Production: How an AMC DSP Farm Can Simplify and Accelerate your Development Efforts

by Relevant Site ContentJul 28, 2008

The emergence of ATCA (Advanced Telecom Computing Architecture) and MicroTCA (Micro Telecom Computing Architecture) platforms, and with them, AMC (Advanced Mezzanine Card) solutions, represents a new era in which developers of telecom, military, medical and other processing-intensive applications are able to reduce internal R&D efforts, as well as manufacturing and operational expenses, by using commercial off-the-shelf (COTS) building blocks from 3rd party suppliers. This trend is driving a wave of new systems and architectures for a wide variety of applications: audio and video gateways for 3G, IMS and other networks, media servers, packet-to-packet applications, session border controllers, cryptography, lawful interception, and medical image processing, to name a few. Many equipment manufacturers are entering the prototype stages today in order to define the systems of tomorrow.

Whitepaper: How to Build a Lean and Mean Video Gateway Using 3G 324M over IP

by Relevant Site ContentJun 04, 2008

Video-based applications in the mobile network are one of the main drivers for the deployment of 3G networks. Both the 3GPP and 3GPP2 standards organizations have adopted the 3G-324M protocol as the primary means of transporting conversational video over mobile networks. Traditional video gateways bridge between the representation of video in the mobile network (3G-324M) and in the IP network (video/voice over RTP). They have substantial disadvantages, however.

Whitepaper: Multimedia iPBX: Moving Beyond Voice Services

by Relevant Site ContentJun 04, 2008

Private branch exchange (PBX) systems have traditionally connected private enterprises to the public switched telephone network (PSTN) using circuit-switched communications. iPBX (or IP-PBX) systems, which use the Internet Protocol (IP) to carry calls over packet-switched networks, have become increasingly popular in recent years. Indeed, iPBXs account for a significant majority of current annual PBX installations, and are projected to further dominate the market in the coming years.

While the move toward iPBX systems represents a clear trend, the ongoing integration of IP within PBX architecture can be viewed as more of an evolution than a revolution. Only recently have enterprises begun to deploy advanced multimedia iPBX systems, empowering a wide array of multimedia services and applications that take full advantage of iPBX capabilities. This paper examines the various stages of PBX architecture development on the road to multimedia iPBX, selected service scenarios enabled by multimedia iPBX, and multimedia iPBX extensions that power implementation of next-generation systems.

Whitepaper: SIP Back-to-Back User Agents for Telecommunications

by Relevant Site ContentMar 27, 2008

SIP Back-to-Back User Agent (B2BUA) Servers are one of the most important and powerful types of SIP Servers used to develop and offer value added features. B2BUA servers are gaining more focus as they become ubiquitous throughout the industry, and are becoming the primary engine for more and more SIP Servers in NGN and IMS networks. This white paper provides managers in the VoIP and real-time multimedia industry an overall understanding of B2BUA servers. Better understanding of B2BUA servers can help managers understand the value, and the tradeoffs, of choosing a B2BUA server as the framework for developing a wide range of SIP applications and SIP services.
