Alcatel-Lucent 1850 TSS-320 Transport Service Switch4
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 trans-
porting 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 Synchro-
nous Optical Network/Synchronous Digital Hierar-
chy (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).
