The Alcatel-Lucent 1850 Transport Service Switch (TSS-3) is a carrier- grade network termination unit (NTU). Providing a rich mix of connectiv- ity and network services options, it is available in a one-rack unit size, mountable in a wall, rack, cabinet or table-top setting. Customer-side Ethernet or Gigabit Ethernet (GigE) interfaces can be aggregated and transported to a central office or node through copper or fiber, using Ethernet or Plesiochronous Digital Hierarchy (PDH). The 1850 TSS-3 can be used to form the basis of an end-to-end Ethernet service. It may also provide Internet Protocol (IP) over Ethernet or over PDH.
