"Our network puts us light years ahead of most other communities. When I came up with the idea of creating a broadband network in Westchester, my goal was to make the county into a world-class business destination," said County Executive Andy Spano. "Not only has it helped us get more business to locate here, but it has also exponentially improved the quality of life for Westchester residents, providing better and more accessible education, healthcare and government services."

Built in 2000, the Westchester Telecom Network is considered to be one of the most robust and sophisticated telecommunications networks in the world. The Network spans 56,982 fiber miles and delivers services to nearly 60 percent of the municipalities located within the County, including nearly 225 government buildings and more than 200 commercial buildings, as well as schools, libraries, healthcare institutions and public safety organizations. The Network has successfully maximized accessibility to government services, improved telecommunications reliability and transmission quality, reduced overall telecom costs by millions of dollars, and boosted overall economic development efforts in the County.

"We're pleased to join with Westchester County to showcase our successful relationship and demonstrate how the Westchester Telecom Network has contributed to the economic success, growth and vitality of the County," said Dave Pistacchio, Optimum Lightpath's Executive Vice President and General Manager. "We look forward to working with Westchester County to further expand upon its vision for a world-class, 21st century business environment."

Two of the Westchester County organizations leveraging the Westchester Telecom Network in innovative ways are Westchester Medical Center and the Rye Neck School District.

Westchester Medical Center, the region's advanced care and Level 1 Trauma Center, offers the latest advances in clinical care, serving more than 3.5 million people in the region. The Westchester Telecom Network enables enhanced communication and sharing of data that is helping Westchester Medical Center to save lives. One example of this is in the Westchester Medical Center's Trauma Center, which often receives trauma patients transferred from other hospitals.

"We've been able to communicate with hospitals that are an hour and a half away from here that send their patients to us by helicopter. We can reach across the network and actually go into their PACS systems and see their imagery that they have taken of trauma patients," said Ted Tully, Director of Trauma and Emergency Services, Westchester Medical Center. "This enables us to alert our surgeons, neurosurgeons and radiologists to let them know that a patient is coming in, so that the time between the patient arriving at the hospital and that patient being taken into the operating room is cut dramatically -- not by minutes but probably by hours. We are definitely saving lives with this type of communication."

The Network is also enabling real-time telemedicine consultations with inmates at the Westchester County Jail. This solution provides a way for emergency room doctors to examine inmates without having to transport them. Since its implementation in March 2007, the program has positively impacted public safety and cut inmate visits to the emergency room by more than 50 percent.

"It's better for patients because they are able to be treated sooner. With telemedicine, we can consult with emergency room doctors almost immediately," said John Moustakakis, CIO, Senior Vice President, Westchester Medical Center. "And it's better for the County because it eliminates the cost of unnecessary trips to the hospital."

The Westchester Telecom Network is also enabling schools in Westchester County -- such as the Rye Neck School District -- to utilize cutting-edge technologies to enable distance learning and various other interactive educational tools in its classrooms.

"Access to Optimum Lightpath technology has changed the complexion of how we deliver education. What is important is that students are engaged and the technology supports student achievement," said Valerie Feit, Enrichment Coordinator, Rye Neck Union Free School District. "With access to broadband, we are able to work with more complex software systems and expand our learning environment beyond the school walls. For example, we have been able to offer gifted students the opportunity to work with high quality content and instructors from Stanford University through the Educational Program for Gifted Youth (EPGY) -- this a very exciting application, and one that wouldn't have been possible without access to the Network."

Westchester County was recently recognized globally for its economic efforts by The Intelligent Community Forum (ICF) as one of the "top seven" most intelligent communities in the world. Gaining a place among the top seven is a major achievement toward greater recognition for Westchester's efforts to use broadband and information technology to attract leading edge businesses, stimulate job creation and generate sustainable economic growth.
