Today flexibility also means the ability to support broadband data services and multimedia applications in the network. The Alcatel-LucentOMSN products offer service providers the ability to deliver several different types of multiprotocol services for the best balance between new broadband data services andhigh-margintraditional-voiceandleased-lineservices.
Alcatel-LucentOMSN products, equipped with ISA plug-in blades that perform Ethernet, ATM or video switching functions, enable new network applications such as 3G mobile aggregation, VPLS and triple play services, with strict QoS and SLA controls. The extensive range of ISApacket-basedengines allows operators and service providers to cope with current and future broadband

traffic needs over transport networks by enabling multiplelayer convergence in a single node. ISA plug-inscan be placed in new or previously installedAlcatel-LucentOMSN devices when and where needed. These blades
improve bandwidth management and reduce both transport infrastructure costs and time-to-marketfor introducing new broadband data services in the network, ultimatelyreducing both capital expenditures (CAPEX) and operating expenditures (OPEX).
Ethernet VPNs and triple play services
The growth, penetration and profitability potential of carrier-class Ethernet services are deeply significant to service providers offering metro and wide-area Ethernet services over an extensive variety of technologies.

When the ubiquity of the opticalnetwork platforms deployed today is considered, optical technologies
represent one of the most compelling opportunities for service providers to leverage their installed base and deliver new revenue-generatingservices (see Figure 2).
Alcatel-LucentOMSN products can be deployed with traditional MSPPs from theAlcatel-Lucentportfolio and emerging packet optical transport devices in the Alcatel-
Lucent 1850 Transport Service
Switch (TSS) portfolio.
ISA-EthernetSwitch(ISA-ES)modules enable new, highly-available
Layer 2 Ethernet service delivery in the metro network through their
With the ISA-ESequipped Alcatel-
Lucent OMSN nodes, service providers can enhance their service offerings with Metro Ethernet Forum (MEF)- certified Ethernet services for business and residential customers.
QoS for Ethernet
As well as mapping Ethernet customer flows onto SDH network resources through standardized mechanisms, theISA-ESseries cardsintroduce wire-speed classification, policing and scheduling capabilities on acarrier-classEthernet switchingblade. These capabilities provide
a cost-effectivesolution for building multiservice aggregation infrastruc tures that are scalable, reliable and capable ofper-serviceSLA/QoS support with:
•Scalable service delivery based on virtual local area network (VLAN),Q-in-Qor MPLS technologies, extended by efficient SDH bandwidthmanagement capabilities
•Sub-50 ms service resilience based on SDH
•Per-flow and per-service SLA guarantees offer accurate band width profiles according to different customers’ applications, to create a measurable, differentiated Ethernet service portfolio and increase service profitabilityby ensuring QoS-specified Ethernet service delivery in any network condition, including faults and congestion.
The ISA-ESblades allow serviceproviders to deliver more than just
Ethernet connectivity service over the optical metro infrastructure. These modules enable service providers to climb up the value chain and offer the newrevenue-generatingservices that both business and residential users are demanding.

ATM backhauling and 3G mobile aggregation
Broadband-dataapplications requiretransport-networkarchitectures capable of processing data traffic flows at native level. The 3G mobile-aggregation application is a key example of how service providers can benefit from the ATM switching integrated into the Alcatel-Lucent
OMSN products (see Figure 3).
The multiservice capability of the Alcatel-LucentOMSN nodes equipped with theISA-ATMblades offers mobile service providers acost-effectivesolution for 3G mobile aggregation in the UMTS terrestrial radio access network.ISA-ATMswitching blades can consolidate ATM traffic collected from different Node
B access devices onto shared SDH virtual container (VC) resources in STM-nrings, and switch the ATMtraffic into the network with QoS support for all traffic classes. Traffic-policing, shaping and congestion-control management features allow a complete range of ATM traffic contracts. For increased service manageability,
ATM OA&M capabilities provide end-to-endfault management and performance monitoring.

Using the Digital Video Broadcasting-AsynchronousSerial Interface(DVB-ASI)blade, theAlcatel-Lucent
OMSN products enable broadcasting companies to transport DVB-compliant signals over the same unique, reliable optical infrastructure. In the past, video transmission across wide metropolitan areas required a costly overlay network separate from voice and data networks due to a lack ofdigital-videointerface standards designed for
WAN transport. The deployment of the DVB-ASI,togetherwith the packet-adaptation capability offered by the frame mapped generic frame procedure(GFP-F),allow packet-based transmission of compressed video signals, including
DVB-S,DVB-H,DVB-TandDVB-Cover the AlcatelLucent OMSN product family (see Figure 4).
Storage area networks
Enterprises worldwide rely on complex information- technology computer structures to store and maintain their mission-critical data and applications. In this scenario, storage area networks (SANs) are the telecommunications industry’s solution for improving the availability, resiliency, performance, modularity and geographical distribution
of storage systems, offering corporations superior capacity and connectivity for their vital information systems.
The Alcatel-Lucent1660 SM andAlcatel-Lucent1662 SMC address SAN applications in metro environments.
Their wavelength division multiplexing (WDM) features, together with the native interfacing capabilities of the 4 x any modules for specific storage applications, including
ESCON, FICON and FC, make them a flexible solution for interconnecting local networks to a centralized storage network, reducing the data-management costs.

Reliable, carrier-classproduct family
Their resiliency features also make the Alcatel-LucentOMSN products ideal for a multiservicetransport-nodesolution. In terms of hardware, maximum reliability isachieved by a 1 + 1 hot standby protection mechanism for all common parts and electrical tributary ports. Matrix, control and synchronization functions are duplicated.
Power-supply protection is inherent, because the DC/DC conversion function is distributed on each card.
For traffic protection, single and dual-endedlinearmultiplex section protection (MSP) and Subnetwork
Connection Protocol (SNCP) protection, with the drop- and-continue function, are provided for improved traffic availability. TheAlcatel-Lucent1660 SM and AlcatelLucent 1662 SMC also support up to 2 x 2 fiberSTM-64orSTM-16multiplexsection-sharedprotection rings (MSPRINGs) respectively. Collapsed singleand dual-node interconnections support cost-effective closure and interconnection of multiple rings.
The Alcatel-LucentOMSN family consolidates the extensive experience gathered byAlcatel-Lucentin optical networks through hundreds of thousands of installations worldwide.
