Hughes Software Systems and Adax demonstrate

pre-integrated IP and ATM solutions at Supercomm 2001

OEMs implementing 3G and Voice over Packet (VoP) networks will be able to cut their time to market, following the launch of an integrated solution today by two of the leading players in the infrastructure market. Hughes Software Systems (HSS), specialists in convergent network software, and Adax Limited, designer of infrastructure hardware and software, have collaborated to develop a single product source for 3G and VoP infrastructure.

The companies are demonstrating pre-integrated IP and ATM solutions at Supercomm 2001, with HSS Signalling Stack M3UA integrated with ADAX SCTP/T(TM) protocol and controller boards for Voice over Packet and UMTS networks.

This combination of higher layer protocol stacks and solutions from HSS, and signalling boards and software from Adax provides OEMs the first complete solution for rapid deployment of VoP and mobile data applications on traditional and new networks.

HSS' M3UA stack has been integrated with the kernel based SCTP/T and HDC board from ADAX, to offer an important building block for VoP Signaling solutions. HSS' MTP 3B stack is also now available with the Adax ATM boards - a critical component of UMTS.

"This partnership provides a solid Next Generation Network infrastructure solution for developers, which can crucially lower time to market for revenue-generating products," explained Barry Zuckerman, President, Adax Inc. "It has come about as a result of an established business and technology relationship which is already providing a broad foundation for VoIP and GPRS applications around the world."

"In partnership with Adax, our continuous emphasis has been to bring pre-integrated solutions to our joint customers and to reduce their time to development and ensure interoperability," said Arun Kumar, President and Managing Director, Hughes Software Systems.
