NASHVILLE, TN — November 15, 2005 — Equinox Information Systems announced that CTC Communications Corp., New England's largest competitive telecommunications provider, has licensed Protector 10.0 for real-time telecom fraud protection. The software will monitor call traffic on CTC's PowerPath network, which uses Cisco Systems packet-based network technology.

Protector 10.0 identifies instances where customer usage deviates from expected patterns in ways suggesting fraudulent activity. The software has enabled hundreds of carriers to reduce fraud losses by differentiating fraud from legitimate usage.

"For voice and data, CTC demands especially stringent security safeguards in our IP+ATM packet network," said John Bouthiette, Vice President of Information Services at CTC Communications. "Network and data integrity are extremely high on our agenda. We chose Protector 10 because it meets the high quality standard we require."

David West, Equinox Executive Vice President, responded: "Our experience with other companies like XO Communications and PAETEC Communications gives us confidence that CTC will successfully leverage Protector 10.0 to reduce telecom fraud."
