BT Enhances Reliable Deployment of Services Using Mu's Service Analyzer.

BT's Comprehensive Proactive Service Assurance Uses the Mu-4000 Service Analyzer for Vendor Evaluation Phase through System Integration & Testing

SUNNYVALE, Calif. -- Mu Dynamics, a pioneer in helping network operators and their vendors eliminate downtime through proactive service assurance, today announced new business with BT (NYSE:BT), a leading global provider of network IT communications solutions. BT is using the Mu-4000 Service Analyzer to support the evaluation and testing of proposed services on the UK's Defense Fixed Telecommunications Service (DFTS) network. BT chose the Mu-4000 based on its systematic ability to quicken the reliable deployment of new services--from initial vendor and equipment evaluation through systems integration and testing.

"With Mu's Service Analyzer we are able to baseline the reliability of every vendor and potential system prior to making a purchase decision--proactively detecting any problems that could lead to disruption or downtime in our production networks," according to Matt Graff, BT's defense account manager. "The automated analysis performed by the Mu-4000 is far more comprehensive than any manual process or point product solution we have evaluated to date, and this will be critical to BT as we implement our next generation of real-time network infrastructure and services."

'Always-Available' Triple Play Applications Depend on Proactive Service Assurance

BT began operating the DFTS network in 1997, and the contract was renewed in 2005 to take it to 2012. The network supports a broad range of services to the 230,000 users at the Ministry of Defence (MOD) who place more than 750,000 VPN calls a day and send two million emails per week through the DFTS EGS (Enterprise Gateway Service). Under the MOD's Defence Modernization Program, BT is in the process of introducing a new core network which aims to enhance services while reducing tariffs paid by the MOD.

"Network operators like BT are vigilantly pursuing comprehensive and proactive service assurance programs by gaining the upper hand on the increased complexity of today's converged IP networks," said Adam Stein, vice president of marketing at Mu. "The Mu Service Analyzer is purpose-built to satisfy increasing complexities. This enables operators to accelerate the rollout of new and enhanced VoIP, IPTV and IMS architecture-based services, while ensuring any NGN service delivers the high levels of availability and reliability needed to maintain customer satisfaction and reduce churn."

The award-winning Mu-4000 Service Analyzer is widely adopted in more than 100 installations at global network operators and their strategic vendors. The Mu solution automates the detection, isolation and elimination of a wide range of weaknesses in IP-based networks and supplier products. This methodical and proactive approach maximizes network operator service availability and network uptime. With the Mu-4000, network operators proactively eliminate many sources of costly downtime, avoid reputation damage, ensure customer satisfaction is maintained at the highest levels possible, and reduce costly customer churn.
