WESTFORD, MA -- Unisphere Networks, Inc. today announced that its SRX-3000 is the industry's first softswitch to complete qualification under Sun Microsystems' Sun Cluster Partner Program (SCPP). The SRX-3000 is the call control and processing solution that provides next-generation voice service delivery to SIP, H.323 and POTS users. By utilizing the exclusive Resilient Telco Platform (RTP) middleware and SUN Cluster software, the SRX-3000 protects against both hardware and software failures with 99.999% reliability. The RTP software platform has proven its reliability in carrier environments with deployments in hundreds of central office sites worldwide. The level of redundancy enabled with SUN Cluster Software and RTP means that both physical nodes of the SRX-3000 can run in active mode simultaneously, ensuring the stability of all calls and billing records even if one node fails. This type of reliability is necessary in a carrier network. "We are pleased to be the first softswitch solution to complete the SCPP qualification process and view this as an endorsement of the carrier-grade reliability that has been built into the SRX-3000 Softswitch," said Tony Scarfo, vice president, Marketing, Unisphere Networks. "This validates our strategy of designing and creating a softswitch that can be deployed in the most reliable and demanding carrier networks." Sun Named Premier Partner in IS POP Partner Program In addition, Sun has been named a Premier Solution Partner in Unisphere Networks' IS POP Partner Program. All of the equipment marketed by Unisphere Networks' Premier Partners must endure a series of carrier-grade interoperability tests, such as fail-over, rolling up-grades, and load tests, to ensure that it fulfills key requirements for central office operation. "We are extremely pleased to be recognized by Unisphere Networks as one of the first Premier partners in the IS POP Partner Program. This signifies our commitment to developing scalable, reliable solutions upon which service providers can build revenue generating services," said Jim Sangster, group marketing manager, Sun Cluster Software, Sun Microsystems, Inc.
