Summary of Contents for Alcatel-Lucent 1850 TSS-3
- Page 1 Alcatel-Lucent 1850 TSS-3 Transport Service Switch A Versatile Network Termination Unit...
- Page 2 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.
- Page 3 The Alcatel-Lucent 1850 TSS-3 meets this broaching need by offering up to 3 Gb/s of Ethernet in the first and last mile, using fiber or copper. The 1850 TSS-3 is a member of the Alcatel-Lucent 1850 Transport Service Switch portfolio, a family of products that is helping businesses move gradually from an all-circuit environment to an all-packet environment, in incremental and affordable steps.
- Page 4 Figure 1. Ethernet Demarcation 1850 TSS-3 In Figure 2, the 1850 TSS-3 is in an Ethernet service-aggregation configuration, in this case acting as a carrier-class Ethernet switch, accepting multiple inputs from the customer side and aggregat- ing them for onward transmission on the network side. Network-side redundancy can be provided by Rapid Spanning Tree Protocol or Ethernet dual homing, two methods for providing automatic backup paths.
- Page 5 1850 TSS-3 Service Provider Equipment Customer Equipment Ethernet/FE 1850 TSS-3 By inserting the 1850 TSS-3 into the copper connection, EoPDH is established. Ethernet packets are mapped to the PDH lines using a standards-compliant mapping mechanism, VCAT/ GFP, with redundancy provided by PDH 1+1 protection. If several E1/DS1 or E3/DS3 lines are available, they can be bonded together to create a higher-bandwidth Fast Ethernet (FE) or rate- restricted GigE pipe.
- Page 6 OAM, link monitoring and remote fault indication. The 1850 TSS-3 acts as a fully non-blocking Ethernet switch, including rate-control and control-protocol processing rules. It also offers Ethernet QoS, as defined by the service provider, at the CPE demarca- tion point.
