The Universal Switch
The Alcatel-Lucent 1850 TSS-320 offers service providers a powerful tool for running future-safe transport networks, with total freedom in planning network resources to support the delivery of new broadband applications such as triple play, video, mobile and Ethernet business services. It also ensures seamless interworking with the existing transport assets that support existing revenues, while fully addressing the optical-packet transport convergence, as demanded by key American service providers. This universal switch fexibly supports scalable aggregation and transport at the wavelength level, the Wavelength Selective Switch (WSS)-based multidegree ROADM, and also at the subwavelength level for both synchronous, or SONET, and asynchro- nous, or packet, traffic. The Alcatel-Lucent 1850 TSS-320 offers the following advantages:
•Any mix of Ethernet, TDM, Wave Division
Multiplexing (WDM), Optical Transport Network (OTN) and future services with only a simple change of interface cards, eliminating the need for future switch investments as new services or protocols emerge.
•Technology-independent, universal switch, capable of switching packets or circuits in their native format and transporting them as they are, without costly mapping of circuits into packets or packets into circuits. The universal switch provides scalable switching capacity regardless of the traffic type.
