In addition it provides the ability to cost-effectively integrate Ethernet services in metropolitan and backbone networks, enabling carriers to generate new revenue streams. The Alcatel-Lucent 1675 LambdaUnite MSS, a global product applicable to both SONET and SDH markets, is deployed worldwide. 2 Alcatel-Lucent 1675 LambdaUnite MultiService Switch Cost-Effective Support for a Variety of Network Applications The Alcatel-Lucent 1675 LambdaUnite MultiService Switch (MSS) is a next-generation optical switch that supports a variety of applications, including add/drop multiplexer (ADM), terminal multiplexer, multi-ring hub and broadband cross-connect. This multifunctional platform helps lower costs by reducing equipment, floor- space and power requirements while improving operational efficiency and network reliability. The system supports both SDH and SONET rates, making it suitable for global network deployments. Its common hardware/software and industry-standards compliance help position you for rapid feature introduc tion and increased revenue opportunities, for small to large office applications in backbone and metro networks. In a Metro Network In a metro network, the Alcatel-Lucent 1675 LambdaUnite MSS serves as a metro hub terminal, efficiently aggregating multiple 2.5G and 10G rings to help eliminate stacked ADMs. An optional passive wavelength division multiplexing (WDM) unit can be integrated for fiber exhaust situations. Alcatel-Lucent 1675 LambdaUnite MultiService Switch 3 4 Alcatel-Lucent 1675 LambdaUnite MultiService Switch In Backbone Networks In backbone networks, efficient use of existing fiber is critical to satisfying bandwidth demands. The Alcatel-Lucent 1675 LambdaUnite MSS efficiently aggregates and grooms traffic to help maximize bandwidth utiliza tion and lower per-bit costs. The optional, fully trans parent OC-48/STM-16 inter - face card can help carriers to costeffectively address wavelength service delivery using the existing SONET/ SDH network infrastructure. Figure 1 shows two complete Alcatel-Lucent 1675 LambdaUnite MSSs in one rack, with a capacity of 640G. Figure 1.

The Alcatel-Lucent 1675 LambdaUnite MSS is well suited for transoceanic applications. The transoceanic protocol mechanism supported by the system helps to effectively protect groomed and consolidated traffic for your valuable undersea fiber route. Seamless Delivery of Traditional Circuit and Advanced Data Services The Alcatel-Lucent 1675 LambdaUnite MSS leverages your existing investments in SONET/ SDH networks to support traditional revenue-generating services while enabling new Ethernet services. Combining SONET/SDH resilience and quality of service (QoS) with the flexibility and ubiquity of Ethernet helps the system deliver carrier-grade Ethernet services in point-to-point and multipoint configurations. The Alcatel-Lucent TransLAN® card option offers efficient and flex ible bandwidth-assignment capabilities, including virtual concatenation and link capacity adjustment scheme (LCAS), to enable voice and data transport and to help avoid separate overlay networks that are costly to build and manage. Central-Office Consolidation Opportunities The Alcatel-Lucent 1675 LambdaUnite MSS performs as a metro hub terminal, efficiently aggregating multiple high-capacity rings in your central office. This deployment can result in significant cost savings by eliminating stacked ADMs at metro hubs. The central ized non-blocking switch is available in 160G, 320G and 640G switching- capacity options in a single shelf, to help reduce floor space and operation costs. High fiber utilization is accom plished using granular STS-1/VC-4 and VT-1.5/VC-12 grooming, a wide range of service interfaces, and advanced data-transport capabilities. Occupying very little floor space because of their high density, two complete Alcatel-Lucent 1675 LambdaUnite MSSs fit in one rack, providing up to 1.2 Tb/s per bay. As shown in Figure 1, the Alcatel- Lucent 1675 LambdaUnite MSS supports various types of traffic and protection schemes — all in one network element. Alcatel-Lucent 1675 LambdaUnite M...
