Alcatel-Lucent and Packet-Optical Transport
The Alcatel-Lucent 1850 TSS family answers the challenges facing service providers. With the Alcatel-Lucent 1850 TSS, service providers can respond with a P-OT solution packet-optimized networks that leverage the installed SDH/SONET infrastructure and provide carrier-class transport capabilities with strong operations, administration and maintenance (OAM). As shown in Figure 2, the Alcatel-Lucent 1850 TSS P-OT approach incorporates the following capabilities: Converged support for SDH/SONET, Ethernet packet and wavelength division multiplexing (WDM) Connection-oriented support for TDM and packet services OAM for services and transport Converged support for SDH/SONET and Ethernet is vital because P-OT systems must support both widely deployed TDM services and traffic from fast-growing IP and Ethernet applications. WDM support is needed to efficiently switch and transport traffic at the optics level. Connection-oriented transport, embodied in the closely related Transport-Multi-Protocol Label Switching (T-MPLS) and MPLS Transport Profile (MPLS-TP), leverages the flexibility of MPLS with transport-oriented OAM features to ensure service reliability and robustness. The 1850 TSS products have the scale and features for the most challenging network transformations you are facing.

Flexible solutions

Service providers must make strategic decisions concerning how to adequately serve the TDM installed base while competing for markets with fast-growing applications and services based on IP and Ethernet. The 1850 TSS product family offers a Layer 1 and Layer 2 approach that leverages existing SDH/SONET network infrastructure, systems and operating expertise. With the Alcatel-Lucent 1850 TSS platforms, service providers can transition gracefully from all-TDM to all-packet transport, while maintaining current transport operating paradigms. Some key solutions classes supported by the Alcatel-Lucent 1850 TSS family include the following.

Mobile backhaul

Mobile backhaul provides transport from the cell site through the aggregation networks to the MTSO and mobile core. The mobile market is experiencing revolutionary growth in applications innovation and traffic volumes with 3G and 4G services deployment. Deployment of IP and Ethernet devices creates an environment demanding backhaul for both Ethernet and the installed base of TDM traffic. With the Alcatel-Lucent 1850 TSS service providers can backhaul TDM and Ethernet over SDH/SONET or Ethernet, depending on the dominant traffic. As traffic shifts more and more toward Ethernet, the Alcatel-Lucent 1850 TSS allows a graceful transition toward a 100 percent packet network at the pace the service provider chooses.

Triple play

Packet-optical nodes provide an optimized, reliable transport infrastructure for triple play services. Operators globally are responding to customer demands with bundled voice, data and video services. Clearly, video is the bandwidth driver for these services and IP services are critical to cost-effective delivery. The Alcatel-Lucent 1850 TSS can provide efficient traffic aggregation, regardless of the access methods employed, and deliver this traffic to the appropriate service points in the network for IP routing and other higher layer services.

Carrier Ethernet

Scalable, robust and secure Ethernet allows service providers to offer Carrier Ethernet service to their business customers and to provide infrastructure for higher level services that rely on Ethernet transport. Key attributes recognized across standards bodies, and enumerated by the Metro Ethernet Forum (MEF), include scalability, hard quality of service (QoS), protection, TDM support through CES, and carrier-class service provisioning and OAM. The AlcatelLucent 1850 TSS family offers a range of MEF-certified Carrier Ethernet platforms meeting these criteria.
Industry and public sector (IPS)
The 1850 TSS has the resilience, flexibility and reliability to support real-time, mission-critical business operations. Many large organizations in industry and public sectors, such as utilities, government and large corporations, deploy networks for their internal mission-critical communications. These networks can be leveraged to offer services to other corporations or government entities. Alcatel-Lucent 1850 TSS solutions offer the flexibility to offer high-bandwidth TDM and packet services to multiple customer organizations with high reliability and resiliency.

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 providers success. The increasing demand for bandwidth for these new services is not reflected in comparable increases in revenue, presenting a significant business challenge. The Alcatel-Lucent 1850 TSS helps businesses maximize their profitability by transporting any service mix while keeping strict control of the costs. The Alcatel-Lucent 1850 TSS is a family of multiservice packet-transport products supporting any mix of traffic, from all-circuit to all-packet. With these products, businesses and service providers can build highly flexible networks that transition from circuit to packet transport gradually, as packet capacity is required, but without disrupting existing traffic or paying for expensive overlay networks. The 1850 TSS family optimizes network efficiencies by aggregating native signals and allowing transport of both packets and circuits.
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.) tall, the 1850 TSS-5s small footprint is designed to extend optical transport to the customer premises. It is ideal for mobility backhaul from the cell site and for fiber-to-the-business (FTTB) and end-user-access applications. The 1850 TSS-5 is environmentally hardened, making it suitable for mounting in outdoor cabinets or at cell towers. Pseudo-wire support of circuit emulation services (CES) makes the 1850 TSS-5 ideal for cell-tower backhaul and the smooth transition from TDM to third-generation mobile system (3G) and fourth-generation mobile system (4G) networks. It has small form-factor pluggable (SFP) optics, allowing the optics to be purchased separately from the circuit packs and plugged in when additional interfaces are needed. This design lowers initial capital expenditures (CAPEX), making the 1850 TSS-5 capacity easily scalable.
Multifunctional Even by todays 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.
The 1850 TSS-5 provides high-speed optical transport for OC-3 and OC-12 linear optical extensions, while unidirectional path switched ring/Subnetwork Connection Protection (UPSR/ SNCP) switching can be used at the synchronous transport signal level 1 (STS-1), STS-3c and virtual tributary (VT) 1.5 levels. Further, only minimal provisioning is
necessary for private-line Ethernet over synchronous optical network/ synchronous digital hierarchy (SONET/SDH) links between two end-points, typically just SONET/ SDH cross-connections. Standard SONET/SDH loopbacks are also supported, including terminal loopback, facility loopback and external optical loopback. The 1850 TSS-5 has several cross-connect capabilities, offering network designers greater flexibility in directing traffic flow through systems to support a wide variety of customer applications using two-way cross-connections. Where a SONET/SDH ring is created, protection switching is done independently for each SONET/ SDH path. UPSR/SNCP rings operate in an integrated, singleended fashion, eliminating the need for complex, network-level coordination in the effort to restore traffic.

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.
Various other functionalities such as Address Resolution Protocol (ARP) and Internet Protocol (IP) tunneling are also supported. For example, Proxy ARP support on the Gateway Network Element (GNE) eliminates the need to create static routes for routing the IP packets from the access network to the embedded network. Alternatively, customers can choose the Simple Network Management Protocol (SNMP), if preferred.

Common Applications

Wireless backhaul using Ethernet or SONET/SDH Enterprise access using Ethernet aggregation into GigE Enterprise access using digital signal level 1 (DS1)/E1 and GigE over SONET/SDH Ethernet extension within an existing building or campus Private line and private LAN services and LAN interconnect

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. In addition, its aggregation capabilities allow the 1850 TSS-5 to backhaul multiple parallel networks simultaneously. With a SONET/SDH network, TDM traffic is carried in native mode and Ethernet is carried by industry-proven Ethernet over SONET/SDH (EoS). As mobility traffic and applications become increasingly data and IP oriented, Ethernet backhaul networks become more attractive. The 1850 TSS-5 offers feature-rich Ethernet services of up to GigE. (see Figure 1).

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. They can start with SONET/SDH backhaul networks and move to Ethernet
backhaul as packet traffic grows, transitioning from TDM backhaul to Ethernet backhaul on the same platform, where and when it makes sense.
Enterprise Services The 1850 TSS-5 provides a low-cost solution for offering high-speed access to small and mediumsized enterprises. The 1850 TSS-5 provides businesses and service providers with reliable transport for both voice and data service. Figure 2 shows the 1850 TSS-5 placed in various buildings with diverse multitenant units. Separate users have distinct voice and data requirements, needing a mix of DS1/E1 and Ethernet connections.

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 access to small enterprise customers, using DS1/E1 and EoS-protected OC-3 or OC-12 lines, and aggregating Ethernet connections for transport over FE and GigE. The 1850 TSS-5 collects traffic from the multiple sources within the building, aggregates them together and then transmits the aggregated traffic by SONET/SDH or Ethernet to basement-located customer premises equipment (CPE) or even directly to the CO. In this application, the 1850 TSS-5 again excels due to its small footprint and its support of both TDM and packet. Within the building it supports greater use of fiber, as opposed to copper, and enables EoS services such as virtual LAN (VLAN) and Ethernet private lines. In addition, the 1850 TSS-5 supports both electrical and optical Ethernet interfaces, greatly increasing network-design flexibility.
