Performance Technologies Announces New Media Blades for VoIP Media Gateways and Server Applications

ROCHESTER, NY - July 22, 2008 - Performance Technologies (NASDAQ: PTIX), a leading developer of communication platforms and systems, today announced the availability of two new media blades, the MB6108 and MB6224, designed to bridge legacy communication systems to VoIP networks as well as for implementing new media server applications.

Utilizing industry-standard CompactPCI® blades, these new offerings allow telecommunication design engineers and system integrators to combine voice and media processing technology that can be integrated to create communication servers, unified messaging systems, media gateways, as well as provide interworking functions or enhance existing communication service applications.

The MB6224 features scalability up to 896 ports of VoIP and provides 24 T1/E1/J1 line interfaces. The MB6108 includes 384 VoIP ports and provides 8 T1/E1/J1 line interfaces. Both blades support wireline and wireless codecs such as G.711, G.726, G.723.1A, G.729A/B, AMR, EVRC, and QCELP. These media blades adhere to PICMG® 2.16 specifications for Ethernet-based packet switching backplane and provide IPMI support for chassis management. Full product specifications for the new media blades can be accessed from the company’s website at http://www.pt.com/products/prodgroup_dsp.html.

Further easing the integration of these high performance products into new and existing communication systems is NexusWare®, Performance Technologies' CGL 4.0 registered, Linux® OS and development environment. NexusWare provides a powerful, consistent API and allows developers deploying the new media blade products to leverage signaling and protocol stacks such as MTP2, SIP, HDLC, and ISDN as well as the required wireline and wireless codecs to bring carrier-grade media solutions to market faster and with fewer resources.

"Our media blade lineup provides crucial building blocks for delivering high density, carrier grade solutions for VoIP applications," said Steven Wigent, product manager for Performance Technologies. "More service providers are shifting their networks to IP everyday and the need to leverage existing infrastructure is going to continue to drive significant growth in the VoIP gateway market. Our new media blades give OEM providers the tools to meet this demand."
