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 high­capacity 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.

Two complete LambdaUnite®MSS systems, with a
capacity of 640G, fit into one rack.
