), a leader in intelligent optical networking Communications between computers, telephones and other electronic devices using light. An optical network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain. See optical fiber. , today announced several new software features and management tools for its complete line of Intelligent Optical Switches. The new features and enhancements deliver flexible protection options across all network topologies See topology. , and advanced capabilities for ring and mesh-based inter-working--enabling service providers to make a business-driven transition to an Intelligent Optical Network. The new management tools make it possible for service providers to manage concurrently ring, mesh, and hybrid networks without disruption to the present mode of operations.

Available now, the new features and tools for Sycamore's Intelligent Optical Switches include:
-- Additional integrated ring functionality, such as 2-fiber and 4-fiber Bi-directional Line Switched Ring (BLSR) and Multiplex Section Shared Protection Ring (MS-SPRing); and the unique ability to interoperate with dynamic protection schemes such as mesh restoral within the same network

-- Increased Broadband Digital Cross-connect System (BB-DCS) and Add/Drop Multiplexer (ADM) functionality with the addition of features such as Integrated Test Access, Good Signal Trigger, and Hierarchical Synchronization Status Messaging

-- New network management tools to expand design, configuration, and management capabilities for ring, mesh, and hybrid network topologies including Silvx Network Modeling Application, Silvx Switch Configurator, and enhanced circuit management capabilities within SILVX(R) Network Management System (SILVX NMS)


By deploying Sycamore's SN 3000 and SN 16000 Intelligent Optical Switches to scale and expand their networks, service providers can recognize capital expense savings of up to 70 percent and ongoing operational reductions of up to 60 percent in comparison to traditional BB-DCS and ADM See add/drop multiplexer.

 build-outs. Additionally, Sycamore's optical switches can seamlessly integrate with existing Operations Support Systems Operations Support Systems (also called Operational Support Systems or OSS) are computer systems used by telecommunications service providers. The term OSS most frequently describes "network systems" dealing with the telecom network itself, supporting processes such  (OSS Oss (ôs), city (1994 pop. 62,141), North Brabant prov., S Netherlands; chartered 1399.

 and ADM network operations functions will enhance the competitive position of Sycamore's SN series with incumbent carriers," said Dave Dunphy, Principal Analyst, Optical Infrastructure at Current Analysis, a leading research firm. "Sycamore's addition of the ring-based protection schemes better positions the company with current carrier needs, and has the advantage of also offering carriers a migration strategy toward more dynamic intelligent meshed architectures for the future."

. Additionally, Sycamore delivers a full edge to core portfolio of completely integrated optical switches that seamlessly interoperate with one another in all topologies and with all protection schemes.

The new BB-DCS and ADM functions announced today further simplify the management and maintenance of Sycamore's Intelligent Optical Switches in a ring network, and extend these capabilities to mesh-based networks. Sycamore's optical switches now support circuit level Good Signal Trigger to reduce and suppress unwanted alarm conditions during the configuration and provisioning process--extending BB-DCS features to an Intelligent Optical Network. With support for Integrated Test Access, the SN 3000 and SN 16000 enable service providers to verify and test that circuits are functioning properly before provisioning live traffic.

 Status Messaging interoperates with both ring and mesh-based networks to improve operational efficiency with respect to network synchronization.

Sycamore's new network management tools simplify the design, configuration and management of ring and mesh-based networks, without disruption to the existing OSS or present mode of operations. The new tools enable service providers to concurrently manage ring and mesh networks, so they can gain the benefits of mesh networks in targeted areas, while maximizing their existing ring-based network assets.

The Silvx Network Modeling Application and Silvx Switch Configurator are new additions to the tightly integrated SILVX InSight(R) family of network design and planning tools. These tools feature an open architecture, simplifying customization and enabling use by diverse business units--such as corporate executives, sales, and finance groups. Service providers can now leverage InSight tools to develop comprehensive, integrated network A network that supports both data and voice and/or different networking protocols. See converged network and new public network.  modeling systems. The Silvx Network Modeling Application gives service providers the ability to model and simulate both ring and mesh network protection schemes and conduct failure analysis. The Silvx Switch Configurator analyzes existing BB-DCS configurations, and then uses a built-in rules expert to determine the best way to grow a network by adding capacity.

Enhanced circuit management capability within SILVX NMS See NetWare Management System.  greatly simplifies the operations, configuration, management, and provisioning of ring and mesh-based networks. Sycamore's application allows for both automatic and manual provisioning of all topologies.

"In the current market, service providers need technologies and products that lower CapEx and OpEx, and interoperate seamlessly with their existing networks--while still building a foundation for more service-oriented optical networks," said Jim Mooney, vice president of product management at Sycamore. "Our optical switches have always been leaders in software intelligence, scalability, and advanced features, and now Sycamore has taken another step to simplify integration and the migration to an intelligent optical network."
