Excel's Multi-Services Platform (MSP) Enhanced to Include Feature-Rich Media Processing Capabilities

Expansion of CSP Product Family Empowers Carriers to Deploy MSP as an Intelligent Peripheral or Service Node Platform in Fixed and Mobile Networks

HYANNIS, Mass.--(BUSINESS WIRE)--Feb. 13, 2006-- Excel Switching Corporation (www.ExcelSwitching.com), a worldwide provider of carrier-class, open services platforms, media gateways, and media servers, today announced an expansion of its popular Converged Services Platform (CSP) product family. Excel is offering immediate availability of robust media processing capabilities in an enhanced version of its award-winning Multi-Services Platform (MSP). Designed for emerging service providers and voice and signaling application developers offering high-value, enhanced voice services for TDM or convergent networks, the MSP can be deployed as an intelligent peripheral or service node platform in fixed and mobile networks.

Expanding upon the success of Excel's flagship Converged Services Platform (CSP), the MSP offers service providers a small-footprint, modular, scalable and cost-effective media resource platform with complementary signaling capabilities, designed for deployment in legacy, convergent, fixed or mobile networks as a classic IN/AIN service node or service switching point. The MSP's highly scalable architecture allows service providers in competitive environments to start small and grow capacity in step with demand, making it particularly attractive for alternative network operators or emerging markets.

The enhanced version of the MSP introduces an integrated media module with digital signal processing capabilities which include: play and record announcements; the ability to receive and detect DTMF tones; tone generation; conferencing; and echo cancellation.

"The enhanced version of the MSP is a perfect example of how Excel is leveraging its two decades of experience providing technologically-advanced platforms that meet the continually evolving needs of the global service provider community," said Peter Vescuso, vice president, market development, Excel Switching Corporation and Brooktrout Technology. "The MSP has already achieved impressive market traction and demand among service providers deploying the platform for applications such as prepaid, multi-ring back tone (MRBT), rich conferencing features, PBX, call center, SMS, IM and location-based applications."

"For years, Emergent has leveraged Excel Switching Corporation's expertise in developing carrier-class equipment," said Nathan Franzmeier, CEO of Allen,TX-based Emergent Network Solutions, a leading provider of open solutions and services to carriers operating in the emerging network. "Excel's recently introduced enhanced MSP reflects the company's extensive development experience and in-depth market knowledge. I believe the MSP, with its robust media processing capabilities, will achieve rapid market acceptance and demand, and is the ideal platform for cost-effectively deploying lucrative next-generation applications and services."
