Sierra Tel Communications Group Installs Equinox Collector Software

COLLECTOR AFT/EIU PROVIDES REAL-TIME DELIVERY OF USAGE RECORDS
FROM NORTEL DMS 100/200 SWITCH

Nashville, TN — November 29, 2005 - 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 Collector AFT/EIU mediation system to automate its call detail record (CDR) transmission process. Collector AFT/EIU downloads records from a Nortel DMS 100/200 switch in real-time via a high-speed Ethernet Interface Unit.

"After evaluating several mediation systems, we selected Collector AFT/EIU because of its price point, speed, and flexibility,” noted Matt Faulkner, IT Director for Sierra Tel Communications Group. “Collector AFT/EIU’s processing speed is a huge plus, and the flexibility of the software to integrate with our Nortel switch via an Ethernet connection made investing in Equinox software an easy decision."

Collector AFT/EIU provides real-time delivery of usage records and supports a number of switch types and communication protocols including X.25, TCP/IP, and file transfer protocol (FTP).

"Collector is a proven mediation system in the communications industry,” commented David West, Executive Vice President for Equinox. "I am confident that Collector AFT/EIU will be a long-term asset to Sierra Tel Communications Group, and Equinox looks forward to supplying Sierra Tel with additional software solutions in the future."
