Petaluma, CA, June 18th, 2007 – Turin Networks, a global provider of metro service edge and optical transport equipment for wireline, wireless, MSO and private networks, today announced that One Communications, the largest privately-held provider of telecommunications services in the country with more than 160,000 business customers, has deployed Turin’s Traverse platform to inter-connect its metro networks and to increase optical backbone capacity to support the company’s IP core network.

Formed in July 2006 through the combination of Choice One, CTC and Conversent Communications, One Communications operates an advanced network that extends across the Northeast, Mid-Atlantic and upper Midwest regions of the United States. The expanding company required a next generation optical backbone network that united the metro area networks in the many markets it serves, while also providing added bandwidth capacity to support the company’s powerful IP core. One Communications determined that a multiservice optical backbone network, using 10G solutions from Turin Networks, offered significant economic and technological advantages over an IP over DWDM approach.

“The advanced bandwidth management and switching capabilities provided by Turin’s Traverse platform allow us to provide the levels of service flexibility and resiliency we determined were essential in our next generation optical core network,” said Russ Oliver, CTO of One Communications. “By simplifying end-to-end provisioning and manageability for both Carrier Ethernet/IP and traditional services, Turin’s solution allows us to leverage our IP core by migrating to a softswitch-based service delivery architecture as well as to launch other advanced new services such as IP peering using GigE.”

Turin Networks is a leader in the IP transformation of carrier networks. As bandwidth-intensive, IP-based applications continue to boost capacity requirements, Turin's powerful network solutions enable carriers to increase capacity while providing greater market agility and improving the ability to deliver new, revenue generating services.

“Turin is proud to be a key component of One Communications’ next generation optical backbone,” said Henry Wasik, president and CEO of Turin Networks. “Wins with landmark customers such as One Communications demonstrate that our products are the premier solution for leading carriers who want to increase the capacity of their optical networks and enable the rapid delivery of new IP-based services.”
