Cost-effectively addresses a variety of network applications

Lucent Technologies LambdaUnite® MultiService Switch (MSS) is a next-generation multiservice optical switch that supports a variety of applications including ADM, terminal multiplexer, multi-ring hub, and broadband cross-connect. This multi-functional 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 at rates including 10G and 40G, making it suitable for global network deployments. Its common hardware, software, and industry standards compliance helps position you for rapid feature introduction and increased revenue opportunities, for small to large office applications, in backbone and metro networks.

In the metro network, the LambdaUnite® MSS system serves as a metro hub terminal efficiently aggregating multiple 2.5G and 10G rings to help eliminate stacked ADMs. An optional passive WDM unit can be integrated for fiber exhaust situations. In backbone networks, efficient use of existing fiber is critical to

satisfying bandwidth demands. The LambdaUnite® MSS efficiently aggregates and grooms traffic to help maximize bandwidth utilization and lower per bit cost. Its optional, fully-transparent OC-48/STM-16 interface card can help carriers to cost-effectively address wavelength service delivery via the existing SONET/SDH network infrastructure.

When deployed with Lucent DWDM systems, you can achieve significant equipment savings by using express optics, since expensive OTUs on the DWDM equipment are eliminated. The LambdaUnite® MultiService Switch is well suited for transoceanic applications. The transoceanic protocol mechanism supported by the system helps to effectively protect the groomed and consolidated traffic for your valuable undersea fiber route.

Supports traditional circuit and advanced data services

The LambdaUnite® MultiService Switch leverages your existing investments in SONET/SDH networks to support today’s traditional revenue generating services while enabling new Ethernet services. Combining SONET/SDH resilience and quality of service with the flexibility and ubiquity of Ethernet helps this system to deliver carrier grade Ethernet services in point to point and multipoint configurations. Lucent Technologies TransLAN® Card option contains efficient and flexible bandwidth assignment capabilities, including virtual concatenation and LCAS, enable voice and data transport, and help avoid separate overlay networks that are costly to build and manage.

Provides central office consolidation opportunities

The LambdaUnite® MSS system performs as a metro hub terminal efficiently aggregating multiple high- capacity rings in your central office. This can result in significant cost savings from the elimination of stacked add/drop multiplexers at metro hubs. The system’s centralized non-blocking switch is available in 160G, 320G and 640G switching capacity options in a single shelf, to help reduce floor space and operations costs. High fiber utilization is accomplished through granular STS-1/VC-4 as well as VT-1.5/VC-12 grooming capabilities, a wide range of service interfaces, and advanced data transport capabilities. Occupying very little floor space because of its high density, two complete systems fit in one rack, providing up to 1.2Tbps per bay.
