The universal switch
The Alcatel-Lucent 1850 TSS-100 offers operators a powerful tool for operating 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 legacy transport assets that support existing revenues, while fully addressing the optical-packet transport convergence, as demanded by operators. This offers the following advantages:
•Supports any mix of Ethernet, TDM, WDM, 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.
•Offers a 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.
•Delivers technology-dependent line cards, packet, circuit or wavelength, where traffic is properly processed according to its native format. The line cards provide native traffic processing.
•Eliminates, by innovatively demarking between traffic processing and traffic switching, the cost penalties traditional transport-node architectures incur with their technology-dependent processing performed in the switch (matrix). Packet and TDM traffic processing resides on the relevant line cards, allowing gradual investment to meet growing traffic requirements.
The concept of a single transport-aggregation platform is a breakthrough in operator networking. Instead of investing in several network layers to provide the required service mix, operators can now choose one platform
that delivers all services. By deploying the 1850 TSS-100 as a unified transport platform supporting any mix of services, operators can:
•Simplify network operations, significantly reducing operating expenditures (OPEX) and increasing the network fexibility and scalability
•Lower the risk of capital expenditures (CAPEX) invest- ments that may vary over time, depending on service- demand changes
•Shorten time-to-revenue for new services
