Optimum Lightpath Cures Bandwidth Ills for Healthcare Providers Throughout New York Metropolitan Area.

JERICHO, N.Y. -- Optimum Lightpath, the next-generation business broadband service provider of Cablevision Systems Corporation (NYSE: CVC), today announced more than 15 healthcare providers in the tri-state area have recently opted for its Metro Ethernet service. Optimum Lightpath's Metro Ethernet service provides significant gains in productivity and cost savings, while enabling better, faster and more valuable application deployments.

The healthcare industry has become one of the fastest-growing markets for information technology (IT) and telecommunications services. According to Insight Research Corporation (http://www.insight-corp.com), the U.S healthcare telecommunications services market is expected to increase at a compound annual growth rate (CAGR) of 5.4 percent, from $6.3 billion in 2006 to $8.1 billion in 2011. This growth is driven by the need for advanced, data-intensive applications such as computerized x-ray systems (PACS), electronic medical record systems and PET imaging (or PET scanning) solutions, which demand exponentially higher bandwidth, speed and capacity in the network.

Some of the healthcare providers in the tri-state area that have turned to Optimum Lightpath's Metro Ethernet services include:

* Saint Clare's Health System - Morris County, NJ is a full-service healthcare system with 470 beds spread across four different hospitals. St. Clare's sees approximately 23,000 inpatient visits and 250,000 outpatient visits annually;

* Holy Name Hospital - Teaneck, NJ is a comprehensive 361-bed acute care medical center that serves more than 17,000 inpatients, 44,000 emergency department patients and 18,000 outpatient clinic and ambulatory surgery patients annually;

* St. Barnabas Hospital - Bronx, NY is a 461-bed acute care community hospital and Level I Regional Trauma Center that provides comprehensive inpatient and outpatient services for more than 500,000 patient visits annually;

In 2006, Optimum Lightpath experienced dynamic growth in the healthcare sector, signing more than 15 new Metro Ethernet agreements in this market.

Saint Clare's Health System, an award-winning, full-service healthcare provider with headquarters in Morris County, NJ saw that Optimum Lightpath could meet the hospital's need for more speed and capacity due to a PACS imaging system deployment at its two main campuses in Denville and Dover. Saint Clare's will use Optimum Lightpath's point-to-point Gigabit Ethernet service to connect more than 3,000 users. In addition, it will use Optimum Lightpath's redundant and resilient fiber-optic network to gain business continuity benefits, so that critical patient records are always accessible to doctors and technicians in the event of a disruption.

"Many of the newest clinical applications, such as those related to imaging, are highly data-intensive. Clearly, the previous 45 Mbps connections we had did not cut the mustard," said Richard Temple, chief information officer, Saint Clare's Health System. "Our upgrade to Optimum Lightpath's Gigabit Ethernet service will help our doctors and technicians deliver better patient care, plain and simple."

In addition to full-service hospitals and healthcare systems, ancillary outpatient care providers, particularly those that specialize in diagnostic imaging technologies (i.e., MRI, CT, PET Ultrasound, Mammography, and Nuclear Medicine) have also turned to Optimum Lightpath's Metro Ethernet services during the last year.

"Bandwidth is rapidly becoming a driving factor in healthcare as the industry makes a concerted effort to utilize new delivery systems and take advantage of advances in clinical treatment technology," said Dave Pistacchio, Executive Vice President and General Manager, Optimum Lightpath. "The momentum and growth that Optimum Lightpath is seeing in this vertical market clearly demonstrates that our Metro Ethernet offering is the right product at the right time - and most certainly at the right price - for an industry that is typically cautious in its approach to IT spending."
