Time Warner Selects Scientific-Atlanta-Tropic Networks Managed ROADM Platform to Simplify and Accelerate Service Provisioning

Time Warner Cable’s Portland, Maine Division Migrates to Reconfigurable Optical Networking to Deliver Maximum Service Flexibility to Customers

May 05, 2005 Ottawa, Canada and Atlanta, GA— Scientific-Atlanta, Inc. and Tropic Networks announced today they will provide Time Warner Cable’s Portland, Maine division with reconfigurable optical add/drop multiplexer (ROADM) transport nodes for its core DWDM network and related support services. This leading technology will enable Time Warner Portland to quickly and remotely modify network topology to optimize bandwidth use and reduce time to service to enhance customer satisfaction. Time Warner Cable expects to rollout its first fully managed and fully reconfigurable network in Portland, Maine, by the second quarter 2005.

“Time Warner continues to see new growth and service opportunities in our core network,” said Chris Graviss, Vice President of Engineering, Time Warner Cable, Portland Division. “By deploying a fully managed ROADM network, we can more efficiently address the growing demand for bandwidth and new services and at the same time deliver maximum service choice and quality to our customers.”

Time Warner Cable Portland has agreed to purchase the WT-24000™ optical transport platform, TROPX software suite and Wavelength Tracker™, advanced optical layer management technology. The managed ROADM solution will provide Time Warner with dual homing master head-end protection for a protected VOD network designed to deliver uninterrupted service to its customers. In addition, the new architecture will support Time Warner’s existing commercial services. The WT-24000’s flexible architecture further provides Time Warner with the ability to create a fully converged network infrastructure as new services can be deployed onto this platform as they become available.

“Managed ROADM network infrastructure based on any-wavelength-to-anywhere flexibility and advanced wavelength management will simplify service provisioning for Time Warner Portland to help provide a variety of operational and cost benefits,” said Bart Spriester, director and general manager for transport networks, Transmission Network Systems at Scientific-Atlanta. “The WT-24000 platform represents an important extension of our current Digital Transport offerings designed to help optimize the use of available bandwidth.”

“This state-of-the-art platform from Scientific-Atlanta and Tropic Networks can help Time Warner Cable Portland leverage its existing infrastructure to extract more value and performance from its network,” said Kevin Rankin, CEO, Tropic Networks Inc. This deployment is a major milestone for us as it validates our strategic relationship, our value proposition and our vision. It proves that the market is ready to deploy best-in-breed managed ROADM solutions to reduce network complexity and control costs.”

The WT-24000 optical transport platform combines leading-edge technology with advanced hardware and software design.
