18-Jul-2007 - Brazilian Customers Telemig Celular and Amazônia Celular Lower Hardware Costs with Evolving Systems' Tertio Service Activation Distributed Architecture Solution

Win represents first deployment of Tertio Service Activation Distributed Architecture solution

ENGLEWOOD, Colorado Evolving Systems, Inc. (NASDAQ-EVOL), a leading provider of software solutions and services to the wireless, wireline and IP carrier market, today announced that Telemig Celular and Amazônia Celular have placed an order to upgrade their current activation system to Tertio™ 7 incorporating the Service Activation Distributed Architecture solution. This deployment is currently in the installation phase and is expected to go live soon.

When choosing an IT platform for business applications, service providers need to optimize the hardware and operating platform for cost of ownership as well as the application workload and service level. For mission-critical applications such as the service activation OSS, this flexibility is particularly important to IT departments being asked to reduce costs without compromising the level and quality of service they provide.

Evolving Systems' Tertio Service Activation Distributed Architecture solution adds multi-vendor support for full application distribution across large numbers of servers, adding the option to scale out (horizontally) as well as up (vertically). Horizontal scalability allows a service provider to start with smaller, low cost servers and easily expand the system as demand increases. It also enables greater flexibility when planning platform transition or consolidation. The result is a substantial reduction in cost of providing a highly scalable and reliable platform together with enhanced business agility.

"We were already in the process of upgrading the IT infrastructure for Service Activation. Our current system configuration provided limited support for peak throughput levels and there was concern over its ability to support any future subscriber growth plans," said Joo Scott, spokesperson at Telemig Celular and Amazônia Celular. "Evolving Systems' distributed architecture feature not only supports the new platform technology, it also enables us to scale economically by distributing the solution across multiple servers, significantly reducing the hardware costs and providing us with a more powerful system."

"Telemig Celular and Amazônia Celular are two of our newest customers and are already taking full advantage of the new features we offer," said Thad Dupper, President and CEO of Evolving Systems. "The Tertio Service Activation Distributed Architecture solution provides operators with a robust and scaleable solution that helps reduce operational and hardware costs by distributing the software across multiple smaller servers."

Key to Profitability

An effective activation system is critical to an operator's profitability. The activation system is involved in providing every service to every subscriber - voice, data, content, information or messaging. The volume of activation transactions handled by operators is huge - and still growing. The activation system needs to support many new network technologies and increasingly complex activation processes as more data and content services are introduced.
