Alcatel-Lucent 1850 TSS-3 Transport Service Switch A Versatile Network Termination Unit
The Alcatel-Lucent 1850 Transport Service Switch (TSS-3) is a carriergrade network termination unit (NTU). Providing a rich mix of connectivity 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).
Key Benefits • Several off-the-shelf, optimized configurations • Transmits Ethernet over any physical uplink • Fast rollout of carrier Ethernet services • An end-to-end, feature-rich solution • Intelligent Ethernet service demarcation • Leading-edge services over Ethernet Versatility, to Meet Customer Needs Customers are using IP-based applications and services at an ever-increasing rate, compelling service providers to converge network infrastructure into an integrated framework capable of supporting very
Multiple Applications Potential applications for the 1850 TSS-3 include: • Ethernet demarcation • Ethernet service aggregation • Ethernet over PDH (EoPDH) • Ethernet extension In Figure 1, the 1850 TSS-3 is in the Ethernetdemarcation role, with the demarcation point shown as a dotted line, representing the point where a single stream of traffic crosses from the customer-owned equipment to the serviceprovider-owned customer premises equipment (CPE).
Figure 3 shows the 1850 TSS-3 in an EoPDH configuration, installed with CPE in a standard building or at a cellular tower. In each case, there is a pre-existing copper connection capable of carrying an E1/DS1 channel or an E3/DS3 channel connected to a legacy synchronous optical network (SONET)/SDH network. By inserting the 1850 TSS-3 into the copper connection, EoPDH is established.
Versatility and Scalability The 1850 TSS-3 goes beyond simple media conversion and physical presence, providing a rich mix of connectivity and network services, offering diagnostics, service monitoring, protection, quality of service (QoS), rate limiting and VLAN stacking for Metro Ethernet Forum (MEF)-compliant Ethernet services.
