Leveraging its universal, open architecture, the Alcatel-Lucent 1850 TSS-320 is positioned to help
service providers migrate their transport networks from all-circuit to all-packet. It integrates a full
set of SONET/SDH features to support traditional transport-network architectures and to interwork
with a large, existing installed base of equipment.
In addition, the platform supports transport packet switching, such as packet operations, administration,
maintenance and provisioning (OAM&P), and integrated G.709 Optical Transport Hierarchy (OTH)
trunk cards. The Alcatel-Lucent 1850 TSS-320 provides a cost-effective solution for implementing
resilient metro and aggregation networks. This solution uniquely transitions from TDM/circuit to
packet transport by smoothly migrating toward the delivery of advanced packet-based services, maxi-
mizing return on investment over the network lifecycle (see Figure 1).
