NASHVILLE, TN — September 19, 2003 — TCAST Communications licensed two Equinox applications for their Plexus platform, extending their existing suite of mediation, traffic analysis, and telecom fraud management solutions to their legacy switch infrastructure.

Equinox intends to pursue additional software licenses with other carriers using the Plexus platform. The Plexus 9000 switch provides carrier-grade switching with softswitch components including media gateway, controller, and signaling gateway for Class 4/5 PSTN, ATM, and IP networks.

"We selected Equinox because of their skill and experience in telecom data processing as well as their willingness to adapt" their applications, according to Mark Jordan, TCAST's CEO.

David West, Equinox's Executive Vice President, noted: "Expanding our line of products to accommodate the Plexus 9000 switch is a natural step in our goal of providing effective solutions."
