UTStarcom (NASDAQ: UTSI), a global provider of IP access networking and services, today announced that it signed a contract with China Mobile to provide its NetRing multiservice optical transport solutions.

The NetRing platform delivers high-density, high-speed aggregation and transport of voice, data, and video services in metropolitan networks. Under the terms of the contract, UTStarcom will deploy nearly 200 NetRing nodes to expand the metropolitan area network of China Mobile in Tianjin.

UTStarcom's NetRing product line provides aggregation, grooming, cross-connect, and transport functionality to deliver high-density, highly efficient STM-1 to STM-64, PDH (E1/DS1, E3/DS3), Fast Ethernet, Gigabit Ethernet, and ATM services in SDH-based carrier networks. All systems support full redundancy, multiple protection options, and in-service upgrades.

The NetRing product family combines Add-Drop Multiplexing (ADM), Digital Cross-Connect System (DCS), Ethernet switching, ATM multiplexing and RPR functionality into an integrated, "pay-as-you-grow" multi-service system. The NetRing optical solutions are among the first to support virtual concatenation, based on relevant ITU standards. With this functionality, carriers can have provisioning granularity in any STS/VC increment, improving Ethernet/IP transport efficiency across SDH networks. UTStarcom's NetRing products also support advanced Ethernet over SONET (EoS) protocols, such as Generic Framing Procedure (GFP), which provides standards-based data encapsulation for efficient mapping of a wide variety of data protocols, including Ethernet, ESCON, FICON, Fibre Channel, and digital video into SDH.
