If you doubt the importance of Operational Support Systems (OSS) in today's unified communications environment, keep an eye on Sigma Systems. I've talked often about how important OSS is to successful service delivery. For me, Sigma provides a great barometer on OSS importance and how well deployments are penetrating the market. Here's new of another win for Preston Gilmer and company over at Sigma.

SIGMA SYSTEMS' SERVICE MANAGEMENT PLATFORM SELECTED BY CHARTER
The Service Management Leader to Automate Provisioning for Telephone and High-Speed Internet Services

TORONTO, ON - June 19, 2007 -- Sigma Systems, the global leader in service management solutions for broadband service providers, announced that Charter Communications, Inc. (NASDAQ: CHTR), third largest publicly traded cable operator in the United States, has selected Sigma to provide enterprise-wide Operation Support Systems (OSS) for Charter Telephone® and Charter High-Speed® Internet services. The agreement provides Charter with an integrated next-generation platform for service provisioning and activation, and resource management across all service domains.

Charter selected the award winning Sigma Service Management Platform (SMP), to seamlessly integrate its business, operational and network management systems, and to provide end-to-end automation of residential and commercial telephone and high-speed Internet service.

"Using Sigma SMP, we expect to enhance the customer experience while improving our operational efficiency," said Marwan Fawaz, Chief Technology Officer for Charter Communications. "SMP will enable us to cost-effectively consolidate several back office systems and Internet protocol (IP) service networks on to a common platform through multi-service provisioning automation."

Sigma's OSS solutions are based on 11 years of broadband IP deployment experience and provide Charter with fully automated order management, business support system integration, self-care integration, resource management, customer service provisioning and network activation. Inter-carrier gateway integration, call feature management and voicemail provisioning are provided for telephone service, along with management of high-speed Internet, email and web hosting.

"Communication service providers have critical need for end-to-end automation for broadband IP services which will allow them to scale business and operational processes, and meet their objectives for customer satisfaction. Our significant deployment experience is a key differentiator, gained from 25 VoIP deployments and 50+ broadband deployments globally," explains Tim Spencer, President and COO, Sigma Systems. "We are honored to be selected as the foundation for Charter's next generation OSS architecture. With choosing Sigma, Charter will benefit from our proven and trusted product portfolio; which provides a common OSS infrastructure for all future broadband IP service offerings.

The first phase of this enterprise-wide deployment is now completed, setting the stage for end-to-end automation of telephone and high-speed Internet services. Future service support for broadband IP services have been subsequently planned and are being implemented at Charter through the remainder of 2007.
