Resumen del manual
The Alcatel-Lucent 1850 TSS-160 is a next-generation, Packet-Optical Transport platform that supports any mix of traffic, from all-circuit to all-packet. With the Alcatel-Lucent 1850 TSS-160, businesses can begin with circuit-based transport and gradually ramp up packet transport by simply changing line cards. The Alcatel- Lucent 1850 TSS-160 supports current traffic requirements while eliminating the scalability issues encountered when traditional multiservice provisioning platforms (MSPPs) are confronted with the high growth of packet- based traffic. The Alcatel-Lucent 1850 TSS-160 offers the flexibility to split increasing traffic demands among any combination of Carrier Ethernet, Transport Multi- Protocol Label Switching (T-MPLS), wavelength division multiplexing (WDM), optical data unit (ODU) and SDH/SONET transport technologies. It offers powerful cross-layer network management and a unified control plane, simplifying operations and reducing the total cost of ownership.
