Open Access Deploys ADC LoopStar Systems to Deliver TDM Services to Mobile Carriers in Long Island and New York City; LoopStar 1600 and 810 Systems Provide Cost-Effective and Scalable Solution.

MINNEAPOLIS -- ADC (NASDAQ:ADCT) (www.adc.com) today announced that Open Access, a metropolitan area network provider, is deploying ADC's LoopStar(R) 1600 and 810 SONET transmission and access systems to provide TDM services to mobile carrier customers in the Long Island and New York City area.

The Open Access optical network provides advanced TDM and Ethernet services and is designed for major enterprises and government entities that require flexible bandwidth to manage future growth. In designing their fiber network, Open Access paid particular attention to performance, reliability and flexibility in order to provide customers with TDM and Ethernet services on a level with those available in other major East Coast metropolitan centers. Towards that end, Open Access selected ADC's LoopStar 1600 and 810 SONET transmission and access systems to provide an economical way for them to capitalize on TDM opportunities from mobile carriers in their metro area, while providing a core infrastructure that supports both TDM and Ethernet services.

"We selected ADC's LoopStar platform for our optical network because it is a cost-effective and scalable TDM delivery solution that best fits our business model and the needs of our business customers," said Robert Mavretich, president and co-founder of Open Access. "The LoopStar 1600 and 810 provide a broad array of capabilities and options that will help us efficiently deliver TDM services to our mobile carrier customers with maximum performance and flexibility and at minimal cost."

To take advantage of opportunities for generating new revenue in their fast-growing markets, mobile carriers are increasing their backhaul spending on technologies that take advantage of the TDM network topology - a trend that will continue for the foreseeable future. Mobile carriers can gain faster time to market and far greater market penetration using TDM rather than an all-packet network.

"We are excited to support the Open Access network that is providing an array of TDM services; all delivered with the performance, reliability, and flexibility that meets the business requirements of Open Access customers," said Hilton Nicholson, president of the Active Infrastructure Business Unit for ADC. "Our LoopStar transmission and access systems allow service providers like Open Access to cost-effectively transport, and manage TDM services to end-user customers from a single platform. With ADC's LoopStar 1600 and 810 systems, Open Access empowers mobile carriers to generate new revenue quickly, efficiently, and affordably."

The scalable LoopStar 1600 is an advanced, next-generation SONET multi-service transmission platform that allows service providers to cost-effectively aggregate, deploy, and manage TDM and Ethernet services. The platform provides an integrated universal back-plane architecture that supports multiple interchangeable network and tributary interface cards that help reduce costs and ease the transition into new business services. The LoopStar 1600, designed for central office and customer premises environments as well as co-location POPs, can be deployed in a broad range of applications such as enterprise access and transport, cell site backhaul and MSC aggregation, DSLAM backhaul and CO interoffice transport.

The LoopStar 810 access system is designed specifically for Customer-Located Equipment (CLE) applications where service providers can deliver Ethernet business services as well as traditional DS1 and DS3 TDM-based services easily and economically. The product's compact design allows for easy installation in customer premises environments with limited space, and its integrated connector-interface panel and wall-mount bracket for complete front access to all cable connections offer multiple deployment options. The LoopStar 810 also features centralized management control with the LoopStar 800 EMS, an advanced, user-friendly Graphical User Interface (GUI) Element Management System (EMS) for controlling and managing the LoopStar access systems. An on-board, Web-Local Craft Terminal is also provided for smaller distributed applications and craft access.
