Entrisphere Implements H.248 Interface in the BLM 1500 Using Data Connection's Megaco/H.248 Protocol Stack

Chicago, IL: June 7, 2005. Data Connection Limited (DCL), the world's leading independent provider of communications protocol software, announced today that Entrisphere has used Data Connection's DC-Megaco/H.248 software to implement an H.248 interface in their BLM 1500 Broadband Loop Multiplexer multi-service access platform.

DC-Megaco/H.248 is part of Data Connection's family of VoIP protocol offerings. These comprise portable source code, full reference designs, test applications, customization tools, and pre-integration with all the leading OS vendors. The protocol solutions, combined with Data Connection's superior customer service organization and unrivaled commitment to quality, provide customers with significant project cost savings and the quickest time to market.

Entrisphere's BLM 1500 multi-service access platform offers major incumbent telecom carriers flexibility and control to deliver a full range of circuit and packet based voice, video, and data applications while migrating their access networks to a simpler and more cost-effective architecture. The use of DC-Megaco/H.248 allows the BLM 1500 to participate in distributed packet voice switching networks, specifically in Line Media Gateway to Media Gateway relationships.

"Scalability and flexibility were the leading requirements for Entrisphere, therefore our DC-Megaco/H.248 solution was the right fit for the task at hand," said Phil McConnell, Data Connection's CEO.

"Our customers are moving to packet voice and softswitching, and an integrated H.248/Megaco interface is critical to meeting their requirements. We were able to complete implementation in the BLM 1500 and certify it as interoperable with the Nortel Succession softswitch on time and on budget," said John Neese, VP of engineering at Entrisphere. "We congratulate Data Connection on their DC-Megaco/H.248 software and the excellent support provided by their team."

Data Connection's other VoIP solutions include DC-SIP, DC-MGCP, and DC-SBC. All these solutions are designed and developed in accordance with Data Connection's renowned architecture for portability, scalability and fault tolerance.
