Equinox Provides GTA With Software For Nortel DMS 250 Switch

Nashville, TN — April 5, 2006 - Nashville-based Equinox Information Systems today announced that TeleGuam Holdings doing business as GTA, a full-service communications company dedicated to enhancing the lifestyles, productivity and future of Guam’s residents and businesses, has licensed Collector and TeleLink.

Collector and TeleLink comprise the Equinox mediation platform, the communications industry’s most advanced system for downloading and integrating usage data from the switch to billing applications and other operational support systems (OSS). GTA will use the mediation software to download usage data from its Nortel DMS 250 switch.

"After a positive experience mediating call data from a cellular switch with Equinox software, it was only natural for GTA to turn to Equinox again for assistance with mediating usage data from our Nortel DMS 250 switch," commented Frank Lujan, GTA Managing Director of IT. "We are particularly excited about TeleLink’s ability to automatically convert our raw switch data to a billing-friendly EMI data format."

"We hope that we can continue to provide GTA with additional software solutions that increase GTA’s bottom line," said David West, Executive Vice President for Equinox. "In light of GTA’s growth plans, Equinox looks forward to expanding the scope of its relationship with GTA in the coming years."
