NASHVILLE, TN — September 19, 2006 — Equinox Information Systems announced that Sierra Tel Communications Group, a California communications provider, has deployed the ShowCDR software system. The implementation enables real-time access to usage records for trouble reporting, fraud investigation, traffic analysis, and customer support functions.

Norma Burnett, Central Office Switching Supervisor at Sierra Tel, expressed satisfaction with the software: "We view ShowCDR as a complementary software application, and we are particularly excited about its ability to generate custom reports on demand."

ShowCDR functions as a user-friendly desktop application enabling non-technical personnel to search switch usage data with real-time reporting capabilities. This functionality supports communication providers requiring immediate access to network management reports.

David West, Executive Vice President for Equinox, commented: "ShowCDR will save Sierra Tel a tremendous amount of time because the software eliminates the need for manual switch-based searches."
