Alcatel-Lucent DSL ISAM Family2

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 bandwidth-

rich 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 high- speed multiservice architecture. With the number of content-rich applica tions and bandwidth- intensive 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 deploy ment 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 – cost-effectively and safely – to the high-margin world of triple play.

As triple play services become more user-centric, as businesses demand more interactive services, and as families simultaneously employ a richer mix of applications, the need for bandwidth grows. The topologies that you employ to meet these demands will naturally vary depending on your subscriber base and density, as well as existing infrastructure. Indeed, you will require a flexible IP/Ethernet-based service delivery architecture capable of enabling multiple deployment strategies, and a means of handling revenue-rich services over fiber and copper within a unified, carrier-grade, IP-based access network.

The Alcatel-Lucent ISAM family has been designed to meet multiple market requirements, as your business case evolves. With the ISAM platform, you can mix and match the most appropriate access technologies, take advantage of your existing copper infrastructure for triple play service delivery, while ensuring full feature parity of your legacy voice offering in a packet-based environment. Alcatel-Lucent’s DSL ISAM family accommodates all ADSL standards, as well as VDSL2, point-to-point fiber, and SHDSL – and offers integrated voice features.1

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 high-speed 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-Lucent7330ISAMFTTNtoservesubscribersfrom cabinets in suburban areas;

•Alcatel-Lucent7356ISAMFTTBREMtoservemulti-dwelling 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 Alcatel-Lucent 7342 ISAM FTTU, another ISAM family member.

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 IntelligenceTo 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.


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 PerformanceIP/Ethernet technology is at the core of the Alcatel- Lucent 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 Alcatel-Lucent ASAM/ISAM broadband portfolio. These include legacy DSL lines deployed from the Alcatel-Lucent 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 ExperienceEven better, your subscribers will have an unsurpassed IPTV experience. Our IGMP support and distributed IGMP offer more and instant channel changes (<200 ms).

Alcatel-Lucent’s aggregation network can also deliver business services on top of the residential services infrastructure, maximizing ROI. In fact, the same infrastructure delivers residential triple play services, next-generation network multimedia/VoIP applications, as well as managed enterprise services using SHDSL.bis.

Invest Once, Reap Twice With the Alcatel-Lucent ISAM family, you get a network ready for NGN and VoIP subscriber lines. So, you needn’t invest twice: once for voice migration and again for broadband services. By migrating the voice access network with the Alcatel-Lucent ISAM family with integrated voice features, you create a broadband access footprint that can be easily leveraged at the right time. To ensure maximum performance and quality, the Alcatel-Lucent ISAM family also distributes the line termination cards in access nodes, and optimizes OPEX, using shared VoIP gateways in central access

nodes. In addition, a high-stability clock and synchronization support ensure high-quality voice services, while providing a cost-effective synchronization solution for mobile backhaul and leased lines.

The Alcatel-Lucent ISAM family with integrated voice support is also the first on the market to offer feature parity from CO and cabinets, allowing cost-effective deployment of triple play services by combining voice, data, and video services on a single IP access platform.

One Management SystemThe ISAM family members in an access network are managed by a single management system - the Alcatel-Lucent Access Management System. The platforms allows you to manage a mixed network of access nodes and remote products from a single management system, greatly facilitating the rapid introduction of new or additional ISAM products.


Operational Excellence

New Services, New RequirementsWith the introduction of high-bandwidth services, your DSL access network will be pushed to its limit. You will need to ensure triple play bandwidth and a carrier-grade platform that is capable of handling the increased complexity of triple play operations. In the past, services such as high-speed Internet (HSI) access did not make excessive demands on your network. But with IPTV over DSL, on-screen errors will be immediately visible to low-tolerance subscribers, leading to increased complaints and operational costs, and higher customer churn. As a result, you need to support video-grade DSL, while being able to scale your triple play network for mass deployment without impacting quality.

Alcatel-Lucent StableDSL Having deployed 143 million lines and enjoying 20 years of DSL experience, Alcatel-Lucent’s product portfolio has been perfected to address the above mentioned requirements.

The ISAM’s DSL line cards are designed to deliver a stable service while maximizing the available bandwidth. For example, Alcatel-Lucent’s DSLAMs offer features that ensure line performance in mixed CO/FTTN/FTTB or mixed ADSL/VDSL2 deployments, and support key functionality for line diagnosis and analysis.

Of course, Alcatel-Lucent keeps innovating and evolving its StableDSL solutions. For example, Alcatel-Lucent invented two technologies (Virtual Noise for VDSL and Artificial Noise for ADSL) that address cross-talk on DSL lines –

the major source of line stability issues. These technologies allow you to stabilize as much as 60 percent of “problem” lines, allowing you to use these lines for revenue-generating triple play services and to reduce the operational cost involved with handling problem lines.

Alcatel-Lucent “StableDSL” is not limited to the DSL access nodes. It also includes the Alcatel-Lucent 5530 Network Analyzer (NA), which provides automated line diagnosis and line management functionality to help you keep OPEX under control. The Network Analyzer offers wire-fault detection, network-wide line classification and analysis, and lets you manage subscribers proactively. The Network Analyzer also offers Dynamic Line Management, which automatically selects the optimal profile for each line. This guarantees that each line always offers the optimal performance, reducing customer complaints, helpdesk costs, and customer churn.


Reduction of OPEXAn equally critical component of Alcatel-Lucent’s commitment to operational excellence for triple play is its CPE (customer premises equipment) Interop Program. By testing the interoperability of the ISAM platform with over 300 CPE devices from more than 40 partners, Alcatel-Lucent gives you its assurance that virtually all DSL and VoIP phone equipment will work with this platform. This translates into less OPEX with fewer truck rolls and deployment of staff.

But if you do encounter problems in the field, you can keep OPEX at reasonable levels with the Alcatel-Lucent Digital Home Care Solution (DHCS). The solution is designed to reduce the cost of customer support as subscribers increasingly install more complex, triple play devices in the home environment.

By addressing the mass deployment challenge of managing home networks, triple play services and customer support interactions for all stages of services deployment with much automation, advanced troubled shooting, and customer self-management, the Alcatel-Lucent DHCS means fewer calls to your help desk, and thus lower OPEX.

Furthermore, Alcatel-Lucent’s consultancy teams are ready to assist you with the introduction of new technologies and the rollout of new services. They’ll make sure you get the most out of your network while keeping OPEX down.

Business-Driven Technical Superiority


New Delivery Model — New Security Challenges

As you prepare your network for triple play services, you will need to ensure that your network is as secure as possible. Because triple play networks are based on Internet stan-dards and technologies, your brand new services, including IPTV, may be vulnerable to content theft and denial-of-service (DoS) attacks.

To respond to this challenge, the Alcatel-Lucent ISAM family enables airtight security across the access, aggregation and edge networks. This gives you the mechanisms to guaran-tee subscribers the requisite quality of experience (QoE). In addition, the ISAM family complements the security features provided by other network equipment such as IP edge routers, Ethernet switches, firewalls and intrusion prevention systems.

Bidirectional ProtectionAs an access node, the Alcatel-Lucent ISAM platform terminates the DSL physical layer towards Ethernet/IP MANs. It can also make a direct termination on IP networks, or go directly towards IP networks. In this respect, the ISAM platform terminates the physical layer from the subscriber’s perspective and interoperates with high-speed links in your network. As a result, the ISAM platform has to shield both the access networks and those beyond it (MANs and IP networks). This is ensured by security mechanisms including, secure MAC learning, IP anti-spoofing, network control traffic filtering and rate limiting.

Limit Access to valid SubscribersMany malicious attacks, especially DoS flooding attacks, rely on address spoofing techniques. For example, bogus packets with invalid MAC or IP source addresses are often used to conceal the real origin of the attack, thereby impeding filtering and track-ing mechanisms.

To minimize this problem, the ISAM platform incorporates mechanisms that use forwarding modes to detect and filter out bogus packets. With these mechanisms, unwanted traffic from malicious subscribers is dropped in the access node. All traffic is therefore traceable to its origin, eas-ing the process of forensic security while ensuring that access is only enabled for valid subscribers.

Finally, the ISAM platform only streams content to author ized sub-scribers. The content is encoded but is only physically delivered to paid-up subscribers. Unlike analog pay-per-view (PPV), it’s impossible to obtain content via an illegal decoder.

Preparing your network for triple play services is a major challenge. There’s no point in disguising the fact that you will need to make significant investments in order to deliver very high-speed broadband services over the access network.

That’s why Alcatel-Lucent developed the ISAM family – the industry’s first IP access platform. With multiple deployment options, you can evolve your network - cost-effectively and efficiently - as your business case grows.

You can also reduce OPEX with multiservice deployment from a single access node, enable a smooth transition of POTS-based services to NGN with full feature parity, as well as maintain stringent parameters for QoS and security so critical for the delivery of triple play services.
