Alcatel-Lucent DSL ISAM Family

As a service provider who wants to deliver triple play services to mass markets, you have a compelling requirement to transition your network – cost-effectively and efficiently - to an infrastructure capable of delivering very high-speed broadband in the most economical way to all subscribers. Anything less just won’t do the job. Among other things, what you need is a robust network capable of meeting the stringent requirements of Quality of Service (QoS) and Quality of Experience (QoE) in the world of bandwidthrich services, such as IP television (IPTV). If, moreover, you’re an established player, you want to re-use your existing copper assets to keep costs down, while wanting to converge PSTN and data traffic over a single access network to lower operational expenditures (OPEX) and remain competitive. With the Alcatel-Lucent Intelligent Services Access Manager (ISAM) family, you can meet these challenges from the ground up, taking advantage of this business-driven platform to generate new revenue while maintaining reasonable levels of OPEX.

Challenges Now more than ever, you are being challenged to transition to a highspeed multiservice architecture. With the number of content-rich applica­tions and bandwidthintensive services expected to grow at unprecedented rates, you must seriously consider evolving your network toward an all-IP infrastructure capable of handling the mass deployment of triple play services. Your access network also needs to be able to support multiple access flavors and network topologies in order to bring fiber to the most economical point. This will let you expand your network in pace with demand. What’s more, you will have to deliver the QoE required to meet subscribers’ high expectations. Just as important, you will have to ensure that operational and capital expenditures remain an acceptable

proportion of the bottom line. To meet this challenge, your access networks will have to be stream­‑ lined by delivering all services – voice, video and data - from a single access node. For voice, you will need the assurance that any migration of your existing voice network to a new IP infrastructure enables full feature parity, and a cost-optimized, unitary management platform. And, for video and data, you will need the assurance of complete availability and stringent parameters for superior quality of service to keep subscribers loyal. Of course, deployment options will vary. If you’re a greenfield operator, FTTH (Fiber to the Home) – with its unlimited bandwidth – is probably the path of choice. If, however, you’re a brownfield operator wanting to maximize existing assets, what you need is an all-in-one access platform

capable of supporting different deploy­ment models in order to reach all subscribers in the most economical way. This will allow you to re-use your existing copper infrastructure to deliver very high-speed broadband services over VDSL2. The good news is that Alcatel-Lucent’s ISAM family of IP access products has been designed from the start with these challenges in mind. Whether it’s the mass deployment of very high-speed broadband, multiservice delivery from a single node, or operational excellence for triple play, this world-class portfolio lets your migrate your network – costeffectively and safely – to the highmargin world of triple play.

Fiber to the Most Economical Point With the advent of triple play services, you will want to exploit your existing copper infrastructure in order to take advantage of this high-margin opportunity. But to assure the quality your subscribers expect, you will need a highspeed DSL infrastructure, plus a platform capable of mass deployment in multiple environments in order to bring fiber to the most economical point. The DSL ISAM family delivers on both of these requirements – cost-effectively and quickly. For example, you can use the: • Alcatel-Lucent 7302 ISAM to serve subscribers from the CO in high-density areas;

• Alcatel-Lucent 7330 ISAM FTTN to serve subscribers from cabinets in suburban areas; • Alcatel-Lucent 7356 ISAM FTTB REM to serve multidwelling units. By distributing Alcatel-Lucent ISAM nodes across your network, closer to the subscriber, you can deliver the high bandwidths necessary to offer triple play services over the existing copper pairs. In greenfield deployments, you can even roll out a fiber-to-the-home network using the AlcatelLucent 7342 ISAM FTTU, another ISAM family member.

Any Line Card, Any Box To deliver even higher bandwidths from your platform, you can simply insert Alcatel-Lucent’s first-to-market 48-port VDSL2 line card. And in deployments where you want to deliver very high-speed services over a mix of copper and fiber infrastructure, you can use the Alcatel-Lucent Active Ethernet (Point-to-Point fiber) line card in combination with the VDSL2 line card.

Very High-Speed Broadband for Mass Deployments The triple play challenge that you face today is simple to state, harder to overcome. That’s because you need to build a service-rich, robust environment capable of scaling for mass deployment while also delivering bandwidth-intensive video applications and IPTV alongside current voice and high-speed data services. For this to happen, data rates need to increase significantly from today’s norm for DSL of a few Mb/s. But this objective can only be reached with a non-blocking, wirespeed architecture.

Distributed Intelligence To meet these wire-speed requirements, the Alcatel-Lucent ISAM family of IP access products employs a distributed architecture – both internally and externally. Internal processing is distributed across all line and network termination cards. Not only does this result in optimal usage of the internal capacity, it also means that the overall processing power goes up by adding more line cards when more users are accommodated. This ensures that every subscriber gets the same optimal service quality, no matter how many are connected.

Figure 3. The ISAM’s internal distributed processing architecture ensures that every subscriber gets optimal service quality, now matter how many subscribers are connected. Traditional Access-Node Design • Centralized processing • Resources shared for all subscribers • Bottleneck/hierarchical architecture for aggregation • Non-guaranteed bandwidth

Limited Penetration of Triple Play

100% Triple Play All Services to All Subscribers

The network termination (NT) card acts as an Internet Group Management Protocol (IGMP) proxy, aggregating IGMP messages towards the upstream network. If 100 subscribers change to a channel, the ISAM will only send a single message to the video servers. In a traditional access node, this would result in 100 separate channel change requests, putting a heavy load on servers, especially during peak moments, such as commercial breaks in sporting events. What’s more, IGMP processing on both the NT card and the line termination (LT) card ensures optimal usage of the bandwidth inside the ISAM. Nothing is wasted: if subscribers on one line card are watching a particular channel, that’s the only one that is streamed to the line card (and then only to those subscribers). So, the NT streams to specific LTs, and the LT streams to specific subscribers, contributing to the enhanced user experience. Externally, the ISAM family allows you to distribute your access nodes geographically, and to locate them close to the subscriber in order to deliver high bitrates. Each member of the DSL ISAM family offers the same service intelligence, which allows you to deliver the same service quality from CO, FTTN, and FTTB deployments. For example: the Alcatel-Lucent 7302 ISAM for COs (copper, xDSL or VDSL2 from CO); the Alcatel-Lucent 7330 ISAM FTTN for cabinets or small central offices (fiber from CO to cabinet, then copper to subscribers, xDSL or VDSL2); and the Alcatel-Lucent 7356 ISAM FTTB REM for MDU deployments (fiber from cabinet to building basement, copper VDSL2 inside the building). As illustrated in Figure 1, the Alcatel-Lucent 7302 ISAM can function as a CO service hub. It is not simply a traffic facilitator, but also serves as a service aggregator to subtend remote units, other COs, cabinets,

or collocated DSLAMs. Optical Ethernet technology enables subtending over long distances and the service hubs provide multiple levels of subtending and cascading. These features allow a single platform to aggregate up to 16,000 subscribers.

Wire-Speed Delivery The Alcatel-Lucent ISAM family guarantees 100 percent delivery of triple play services to all subscribers. Wire-speed forwarding of all packets eliminates packet loss and controls latency. With the Alcatel-Lucent DSL ISAM platform, the recommended minimum data rate of 20 Mb/s is achieved over copper using ADSL2+ or VDSL2 line cards on the Alcatel-Lucent 7302 ISAM, 7330 ISAM FTTN, and 7356 ISAM FTTB REM.

Multiservice Access Minimize Cost, Maximize Performance IP/Ethernet technology is at the core of the AlcatelLucent ISAM family. It is capable of aggregating different services from IP-enabled line cards at the Gigabit Ethernet core, including legacy POTS and ISDN subscriber interfaces. This approach ensures minimal delay for voice, minimal cost regardless of the service mix, the same operation for any service, and pure IP/VLAN QoS control - end to end. Equally important, the Alcatel-Lucent ISAM family delivers one access node for all services – whether it’s IPTV, mobile backhaul, high speed and symmetrical business services. All services run from a single multiservice IP/ Ethernet access node. Furthermore, you can manage all services with one network management system, which is fully compatible with every product in the AlcatelLucent ASAM/ISAM broadband portfolio. These include legacy DSL lines deployed from the AlcatelLucent 7300/7301 Advanced Services Access Manager (ASAM), as well as the new Alcatel-Lucent ISAM platforms. The result is a significant reduction in OPEX.

Unsurpassed Quality of Experience Even better, your subscribers will have an unsurpassed IPTV experience. Our IGMP support and distributed IGMP offer more and instant channel changes (
