Alcatel-Lucent 1850 TSS-5 Transport Service Switch Modular Aggregation and Transport Unit
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.
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 transport 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 success.
Flexible and efficient aggregation and transport, meeting the evolving needs of multiservice access networks. 1850 TSS-5: Where TDM and Ethernet Services Coexist The 1850 TSS-5 is a compact, modular, optical transport switch with the functionality to carry TDM traffic from 1.544 Mb/s interface/2.048 Mb/s interface (T1/E1) to optical channel level 12 (OC-12), and packet traffic from 10 Mb to Gigabit Ethernet (GigE). It is recommended for use where TDM and Ethernet services coexist. Less than 125 mm (5 in.
Multifunctional Even by today’s competitive standards, the 1850 TSS-5 is distinctly versatile and multifunctional. Fast Ethernet (FE) traffic can be aggregated onto up to 4 GigE ports and these ports can be electrical or optical, depending on the available or desired infrastructure. The 1850 TSS-5 supports carrier Ethernet services such as point-to-point Ethernet line (E-line) and virtual Ethernet LAN (E-LAN) with robust, standards-based quality of service (QoS) and reliability.
Management and Performance Monitoring Where required, the 1850 TSS-5 comes with a craft interface terminal (CIT) that manages SONET/SDH operations though a standard RS-232 or LAN port. A full-featured graphical user interface (GUI) may be used or, if preferred, transaction language 1 (TL1). Performance monitoring is also provided and software upgrades can be downloaded by FTP without a truck roll.
Versatile Applications Mobility Backhaul The 1850 TSS-5 supports backhaul for all wireless technologies, including: • Code Division Multiple Access (CDMA) • Global System for Mobile Communications/Universal Mobile Telecommunications System (GSM/UMTS) • Wideband Code Division Multiple Access (W-CDMA) • Worldwide Interoperability for Microwave Access (WiMAX) Mobility second-generation mobile system (2G) and 3G traffic is accommodated using Ethernet or SONET/SDH transport.
The 1850 TSS-5 supports graceful migration from TDM 2G services to fast-growing Ethernet- and data-oriented 3G services. With Ethernet backhaul, the 1850 TSS-5 supports TDM traffic by CES. In CES, TDM is transported over Ethernet by static multiprotocol label switching (MPLS) pseudo-wires protected by bidirectional forwarding detection (BFD), a form of label switched path (LSP) protection. By using the 1850 TSS-5, businesses avoid making a premature SONET/SDH or Ethernet backhaul decision.
For enterprise services, the advantages of installing the 1850 TSS-5 include: • Saves space, courtesy of the small footprint and avoiding the use of separate data switches • Uses low-cost fiber terminations at the customer site • Supports a variety of connection types and speeds, offering service flexibility • Offers remote operations and monitoring from the central office (CO) • Provides SONET/SDH-based protection for both voice and data Figure 3 illustrates a low-cost solution for bringing high-speed acc
Transition to the Future The 1850 TSS-5 is a compact, feature-rich network element, small enough and with sufficient environmental hardening to operate in hostile environments such as cell sites, and in virtually any CPE situation.
