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, fexibly 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).
