Optimum Lightpath Receives New York State Public Service Commission Commendation for Excellent Customer Service.

Ninth Consecutive Year Optimum Lightpath Has Been Honored

JERICHO, N.Y. -- Optimum Lightpath, the next-generation business broadband service provider of Cablevision Systems Corporation, today announced it has been awarded the New York State Public Service Commission (PSC) Commendation for Excellent Customer Service in 2006. Presented annually, the award recognizes telephone companies that consistently provide the highest levels of service and quality to customers in New York State. This marks the ninth consecutive year Optimum Lightpath has been so honored by the PSC, having been awarded the commendation every year since 1998.

"Optimum Lightpath prides itself on delivering the highest level of quality to our customers," said Dave Pistacchio, Executive Vice President and General Manager, Optimum Lightpath. "Along with the recognition we received for our Metro Ethernet initiatives in 2006, this commendation underscores Optimum Lightpath's ongoing commitment to customer satisfaction as a top priority while moving forward with innovative and valuable delivery of advanced business services across the Tri-State area."

In June 2006, Optimum Lightpath was recognized by the Metro Ethernet Forum (MEF) as the North American "Carrier Ethernet Service Provider of the Year" in the category of "Outstanding Innovation." The company received the MEF's "Carrier Ethernet Certification" in April 2006, recognizing Optimum Lightpath as the first North American MSO to be certified Carrier Ethernet compliant by the organization.

"This commendation signals what the market has known for some time - businesses get the utmost reliability and responsiveness from Optimum Lightpath, as well as the most advanced telecom services available today," said Kevin Curran, Senior Vice President of Marketing for Optimum Lightpath. "We make it a requirement to consistently exceed not only the customer service standards set by the New York State Public Service Commission but also the high standards we know our customers have come to expect from our services."

The annual commendation recognizes excellent customer service based on providers' performance relative to service quality standards set forth by the PSC. The commendations are based on two metrics: The Customer Trouble Report Rates (CTRR) and the PSC Complaint Rate, or the number of complaints received each year by the Commission per 1,000 access lines.
