1850 TSS-320
Transport Service Switch
The Alcatel-Lucent 1850 Transport Service Switch (TSS)-320, a new class of multiservice
transport platform for metro-core and regional applications, supports any mix of traffic,
from all-circuit to all-packet. This universal switch uniquely addresses the transition from
TDM/circuit to packet transport, eliminating the blocking problems encountered when
traditional platforms face data-traffic increases. The functional versatility of the 1850 TSS-320
allows service providers to support current demands on their network, while positioning
their infrastructure for the future growth of advanced service delivery and traffic.

Transforming Transport Networks
To stay profitable, service providers must focus on new revenue-generating services
while carefully controlling their cost structures. At the same time, new bandwidthhungry services, such as triple play and Ethernet virtual private networks (VPNs),
are redefining the underlying transport-infrastructure requirements. These changes
are driving the move from circuit-based transport, using Time Division Multiplexing
(TDM), to packet-based transport, using Ethernet in MANs and WANs.
Driven by end-user demand for new services, service-provider network capacity is
growing rapidly, with these networks transporting a wide variety of traffic. Service
providers all need to assess how their existing metro and core networks will accommodate
trends and transitions in traffic patterns.
The new-services introduction is probably the most critical factor to a service provider’s
success. The increasing demand for bandwidth to deliver new services is not reflected
in comparable increases in revenue, presenting a significant business challenge. The
Alcatel-Lucent 1850 TSS-320 helps service providers maximize their profitability by
transporting any service mix while keeping tight control of costs.

Multitechnology Support
with the Alcatel-Lucent 1850 TSS-320
The Alcatel-Lucent 1850 TSS-320 represents the
next step toward a converged transport network.
It is a single transport-aggregation platform for
switching packets and circuits, seamlessly transporting any type of service in any possible mix,
allowing service providers to build future-safe
transport networks that can support future traffic
requirements. The industry’s first transport service
switch, it uses an open architecture that integrates
Ethernet switching, TDM switching, using Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) and dense wavelength division
multiplexing (DWDM), with reconfigurable optical
add/drop multiplexer (ROADM) functionality.
This unique capability makes the Alcatel-Lucent
1850 TSS-320 an ideal building block for the ongoing
transformation of transport networks, flexibly splitting
increasing traffic demands among any combination
of carrier-Ethernet switching, DWDM and TDM
transport technologies. This allows service providers
to overcome scalability and technology issues,
regardless of future traffic-pattern changes.
Service providers no longer need to debate which
transport technology is the most appropriate to
deliver their current or future service mix. The
Alcatel-Lucent 1850 TSS-320 offers them all
(see Table 1).
