The Alcatel-Lucent 1850 Transport Service Switch (TSS-5) is a carrier-grade aggregation and transport device for meeting the changing needs of multiservice access networks. This compact, modular optical transport switch is ideal for carrying circuits or Ethernet over Time Division Multiplexing (TDM) or packet networks. Supporting any mix of traffic, from all-circuit to all-packet, it is ideal for use where TDM and Ethernet services coexist. 2 Alcatel-Lucent 1850 TSS-5 Transport Service Switc

The Alcatel-Lucent 1850 TSS Family New bandwidth-hungry services, such as triple play and Ethernet virtual private networks (VPNs), are placing great demands on the existing trans- port infrastructure. To remain profitable, businesses and service providers are embracing these new revenue-generating services by moving from circuit-based transport, using TDM, to packet-based transport, using Ethernet. The new-services introduction is probably the most critical factor to a service provider’s su
