SCTE Cable-Tec Expo 2010: Suddenlink Makes IP Voice Fail-Safe

MSO Deploys Genband C20 Softswitches for Disaster Recovery

Suddenlink Communications will lets its voice-over-IP subscribers keep talking -- even in the event a hurricane or other disaster knocks one of its facilities offline.

The MSO, the seventh-largest U.S. cable operator with 1.3 million customers, has fully deployed Genband's C20 Converged Softswitch with a geographically survivable telecommunications systems core to ensure subscriber IP voice calls can go through.

Suddenlink deployed the Genband C20 softswitches in multiple locations as part of its business-continuity and disaster-recovery preparedness plan. The solution provides geographic redundancy across Suddenlink's 18-state footprint, so that if one softswitch or location fails another can pick up without affecting any active calls or reducing the network's existing capacity.

"We have enjoyed considerable growth for our residential and business cable voice services over the past few years," Suddenlink chief technology officer Terry Cordova said in a statement. "To address this growth and also ensure we continue to offer reliable, best-in-class service, we selected Genband to deploy geographic redundancy capabilities so a disaster at any single facility would not impact our subscribers' communication service."

Genband is also providing Suddenlink with certain professional services capabilities to support their geo-deployment. Plano, Texas-based Genband claims the C20 is the most widely deployed VoIP softswitch in the industry, with products deployed in 600 customer networks in 80 countries.
