Sierra Tel Communications Group Licenses ShowCDR Software

SHOWCDR OFFERS EASY ACCESS TO USAGE RECORDS FOR RESEARCH & ANALYSIS

Nashville, TN — September 19, 2006 - Nashville-based Equinox Information Systems today announced that Sierra Tel Communications Group, a leading provider of communications services in California's Central Sierra, has installed the ShowCDR software system to obtain real-time access to usage records for enhanced trouble reporting, fraud investigation, traffic analysis, and customer support.

"Sierra Tel has had excellent results with Collector, an Equinox software application that we installed on our Nortel DMS 100/200 switch last year," said Norma Burnett, Central Office Switching Supervisor for Sierra Tel Communications Group. "We view ShowCDR as a complementary software application, and we are particularly excited about its ability to generate custom reports on demand."

ShowCDR is a user-friendly desktop software application that allows non-technical users to navigate switch usage data by providing real-time searching and reporting capabilities. This real-time reporting is invaluable for communication providers that require up-to-the-minute reports to manage their network.

"After a successful installation of Collector in 2005, Equinox is proud to expand our relationship with Sierra Tel Communications Group in 2006," noted David West, Executive Vice President for Equinox. "ShowCDR will save Sierra Tel a tremendous amount of time because the software eliminates the need for manual switch-based searches."
