The Alcatel 7301 ASAMAdvanced Services Access Manager

Feature Group 1 (ANSI Version) Release 5 (ETSI Version)

Alcatel is at the peak of the DSL deployment learning curve.

The result? Our fifth generation ASAM platform. The Alcatel

7301 ASAM extends bandwidth capacity to deliver video

streaming, broadcast video, video on demand, and gaming.

It also satisfies the market demand for carrier-grade business

access and reduces operational expenditures by improving the

economies of scale. Upgrading from the installed base of existing

Alcatel 7300 ASAMs can be achieved with minimal impact,

renewing the value of the platform for future service deployment.

ALCATEL 1 >

Alcatel has the largest installed base of DSL

access multiplexers (DSLAMs) in the world,

with more than 25 million DSL lines shipped.

According to Dell’Oro, this is almost four times

as many as our nearest competitor. The Alcatel

7301 ASAM continues to enable economical

mass-deployment of cutting-edge broadband

access services. The Alcatel 7301 ASAM uses

DSL technology to deliver high-bandwidth access

and new revenue-generating broadband services

over existing telephone wiring and/or fiber

terminations. It also will enable future combined

deployment of copper and fiber (PON) access

on the same platform.

The Alcatel 7301 ASAM has been designed

from the ground up to explicitly meet today’s

advanced market requirements:

> Future proof bandwidth engine

> Cost-effective grooming

> Advanced business access services

> Multimedia readiness

> Low impact, high value upgrade

THE FIFTH GENERATION ALCATELASAM: WHAT THE MARKET WANTS

> 2 ALCATEL

Service penetrations of 30 percent and more are

driving the need for a new way of deploying DSL.

The answer to this need is higher capacity

DSLAMs and higher bandwidth aggregation.

High-speed Internet (HSI) access continues to

be the foundation of the broadband network

business case. The advantages made to the

Alcatel 7301 ASAM are designed to further

improve the business case in view of increasing

DSL household penetration and usage beyond

the PC-owning households.

In addition, service providers can start to

differentiate their services to retain and attract

new customers. This can be done if a healthy

HSI network already exists. In addition, service

providers need to have a broadband platform

enabling them to offer a range of compelling

services. These new services in the multimedia

or entertainment space will lead to even higher

first/second mile bandwidth needs, increasing

the challenges for a healthy operator.

The Alcatel 7301 ASAM provides economies

of scale by increasing the ASAM density and

bandwidth capacity in a cost-effective way.

The core of the Alcatel 7301 ASAM is based

on a future-proof bandwidth engine, capable of

processing a huge amount of traffic, including

data, voice, video, and business-corporate traffic.

The Alcatel 7301 ASAM offers protection for

service provider investment with a high capacity

architecture supporting over 10,000 users on a

170 Gb/s back plane with switching capacity of

over 5 Gb/s. In addition, each slot has access to

a total bus capacity of up to 1.4 Gb/s.

It also supports multistage subtending and

management for up to 2,000,000 users and

4,000 nodes for a truly scalable network.

The Alcatel 7301 ASAM is the answer for broad-

band copper-based deployment, offering multiple

classes of DSL service (ADSL and SHDSL, with

VDSL, READSL2, ADSL2 and ADSL2plus coming

soon) with ATM and IP QoS capabilities. All of

this is combined with the robustness of the Alcatel

7300 platform so widely deployed across the world.

A FUTURE-PROOF BANDWIDTH ENGINE

ALCATEL 3 >

COST-EFFECTIVEGROOMINGReaching Further with Maximum Geographic CoverageTo increase market reach, service providers

are looking to extend DSL network coverage

to reach all potential DSL subscribers in low

penetration areas. The Alcatel 7301 ASAM can

be configured in a network as a host, supporting

multiple remote DSLAMs using the optical or

electrical subtending interfaces. Service providers

have an economical solution for maximum

coverage in remote areas in combination with

the ability to deliver a maximum amount of

bandwidth, enabling a broader service offering

to a wider public.

The Alcatel 7301 ASAM is highly scalable, allow-

ing service providers to reach more potential

DSL customers for small to large system deploy-

ments. The capacity of small systems can be

extended easily to meet the growing demand.

The centralized hub architecture of the Alcatel

7301 ASAM lowers the “second mile” costs both

in terms of capital expenditures (CAPEX) and

operating expenditures (OPEX). The Alcatel

7301 ASAM offers DSL-centric grooming, with

lower port costs. Early grooming of xDSL-centric

traffic creates OPEX savings because expensive

transport links are better dimensioned, and there

is no need for all xDSL-centric traffic to be ter-

minated at a central switch point. Owing to the

nationwide coverage of DSLAMs, the Alcatel 7301

ASAM can aggregate DSL-centric traffic, more

effectively optimizing the transport capacity.

The Alcatel 7301 ASAM supports a wide variety

of interfaces, such as OC-12/STM-4, OC-3/STM-1,

4 x STM-1, T3/E3, T1/E1 and Ethernet. This

offers service providers the flexibility to choose

from many options for edge and backbone

networks.

Seamless Interconnection with EMAN NetworksThere is an emerging trend to use Ethernet

metropolitan area networks (EMANs) for DSL

aggregation. Since current deployments are

largely ATM-based, the Alcatel 7301 ASAM

provides efficient STM-1 and STM-4 interfaces.

Nevertheless, and in view of the EMAN trend,

it will also provide a feature-rich optical GigE

interface allowing operators who choose

Ethernet aggregation to use the Alcatel 7301

ASAM in the most optimum way.

The GigE interface is configured with standard

virtual LAN (VLAN) functions and is capable

of forwarding traffic via cross-connect mode

or bridging mode. To ensure a robust and safe

implementation of Ethernet aggregation with the

GigE interface, the Alcatel 7301 ASAM controls

the uniqueness of the medium access control

(MAC) address, blocks the broadcast storms

of the Ethernet layer and prevents user-to-user

communication. These features are particularly

important for the VLAN bridging/VLAN home

bridging modes.

ALCATEL 5 >

In cross-connect modes, permanent virtual

connections (PVCs) are uniquely linked to one

single VLAN, and the security of the information

is ensured. The resulting quality of service (QoS)

combines the best from both the DSL/ATM and

Ethernet worlds.

It is important to add that the implementation

of the GigE interface allows service providers

to work simultaneously with ATM and EMAN

aggregation networks. In this way migration

of networks and traffic from one technology to

another is flexible. This is specifically valuable to

tune migration to EMAN aggregation to availability

of features required for end-user services. It also

allows service providers to focus on the

deployment of EMAN networks toward the

traffic generated by new services, leaving

the HSI traffic and operations untouched.

New Services ThroughCentralized IntelligenceThe hub architecture of the Alcatel 7301 ASAM

allows service providers to introduce video

streaming, portal services and services from

content delivery networks (CDNs) in a cost-

effective way. Large ASAM configurations allow

for local content insertion, large-scale packet

insertion and portal services.

One example is the IP Services Module (ISM),

which expands the power of the Alcatel 7301

ASAM to offer IP and broadband remote access

server (BRAS) functions, and features such as

IP multicast, DSL aggregation, and local Ethernet

connectivity in the access network. The ISM is

a two-slot line termination card that slides into

the front of the Alcatel 7301 ASAM.

ADVANCED BUSINESS ACCESS FEATURESDSLAMs have tremendous global coverage,

which makes expansion of services to the

business market a very attractive and lucrative

proposition. The Alcatel 7301 ASAM is designed

to serve up to 10,000 users. Combining business

and residential customers strengthens the overall

business case. For example, with 2,000 business

customers and 8,000 residential customers per

ASAM, the total monthly revenue potential is

maximized. These 2,000 business access cus-

tomers can generate the same or more revenue

than the 8,000 residential customers. In other

words, 20 percent of an ASAM’s customer base

can equal 50 percent (or more) of its revenue

potential while using just 10 percent of the

ASAM’s available bandwidth.

The total revenue potential for business access

on a single Alcatel 7301 ASAM is several hundred

thousand Euros. An example of the ARPUs is

shown in Table 1.

Business customers have requirements that are

different from residential customers, including:

> Greater and symmetrical bandwidth

> Business-quality access

> Voice services

> VPNs

> Interconnection of multiple sites

> Intranet and extranet

> Internet and e-mail hosting

> Videoconferencing

> E-commerce

> Security features such as firewall management

and virus checking

Figure 2 - Alcatel 7301 ASAM Service Scope for Business Access

The Alcatel 7301 ASAM platform has been

designed to cover the needs of the small office

home office (SOHO) and small to medium enter-

prises (SMEs), as well as the requirements of

the corporate market. The increased capacity

(bandwidth as well as the number of users) of

the Alcatel 7301 ASAM makes virtually unlimited

business access deployment feasible. Differen-

tiating service level agreements can be offered

via the VP shaping function and the multi-QoS

support, which ensure that the proper bandwidth

is provided to your customers and that no limits

are exceeded. The GigE/STM-1 or STM-4 termi-

nation makes it possible to connect corporate

customers, reusing first mile DSL investments

for higher bandwidth business customers.

The Alcatel 7301 ASAM provides an evolutionary

path to a next-generation voice and data network.

It supports legacy applications while enabling a

gradual transition from circuit- to packet-based

networks.

Today we provide access to traditional voice

switches. The Alcatel 7301 ASAM also enables

voice and data on a single DSL connection through

integrated voice over DSL (VoDSL) cards, or a

centralized voice gateway. This enables a direct

V5.2/TR-303/TR-008 interface accessing voice

switches. In the future, the voice traffic will be

open to a next generation switching platform

(H.248/Megaco).

In order to maintain and expand their customer

base and increase revenues, service providers

can take advantage of the installed DSL base

to offer broadband services such as streaming

video, VoD, PC TV, and other value-added serv-

ices. The total revenue potential for multimedia

services on a single Alcatel 7301 ASAM is several

hundred thousand Euros. An example of the

ARPU is shown in Table 2.

Alcatel has created an end-to-end standards-based

solution for video services, such as personal video,

broadcast TV, VoD, and e-commerce. The Alcatel

7301 ASAM is ready for video applications on

various end-user platforms, such as personal

computers and televisions. It has been deployed

in various places to provide advanced VoD

services, but can also be used for cost-optimized

video broadcast.

MULTIMEDIA READY

The built-in multicasting functionality eliminates

replicated traffic in the network, significantly

reducing transport costs. Services can be delivered

closer to the end users with optimal network

performance ensured, and users can selectively

join or leave real-time audio or video multicasts.

The backplane architecture is specifically designed

to offer broadcast services. The broadcast video

bus of 622 Mb/s can simultaneously deliver up

to 250 video channels to 10,000 users. In addition,

IGMP messages are interpreted locally on the

network processor to reduce latency and

increase efficiency. The unique multicasting

policy enforcement feature creates an additional

level of security: it makes sure that multicast

streams are mapped on a per port basis with the

subscriber, omitting channel fraud. The IGMP

channel management is already integrated in the

element management system of the Alcatel 5523

AWS, making mass deployment of multimedia

services possible today.

LOW IMPACT, HIGH VALUE UPGRADEThe Upgrade PropositionWith the largest installed base of DSLAMs in the

world, Alcatel designed the Alcatel 7301 ASAM

to provide seamless upgrades to existing systems.

Service providers can mix the Alcatel 7301 ASAM

shelves with installed shelves like the 1000 ASAM

(subtended) or Alcatel 7300 ASAM (upgraded or

subtended). This creates a single system that

delivers enhanced functionality and ensures

backward compatibility while preserving past

investments. Typical upgrades with the Alcatel

7301 ASAM cost only a fraction of the cost of a

conventional DSLAM, adding much more value

to the Alcatel 7301 ASAM itself, while allowing

efficient use of the installed base. With respect

to the broader revenue potential, the pay-back

time of an Alcatel 7301 ASAM upgrade is

typically less than one year.

Further, the migration to the Alcatel 7301 ASAM

is based on a unique procedure: the replacement

of the network processor board and the extender

chain. Existing backplanes are re-used and latent

data busses are enabled. This is done via an

offline migration procedure, reducing the service

outage to a minimum. Beyond hardware

interconnectivity and software consistency, the

easy migration from previous releases to new

releases is enabled through the use of the Alcatel

5620 Network Manager (NM) and the Alcatel

5523 AWS (in the ETSI market) or Alcatel 5526

AMS (in the ANSI market), simplifying the

integration of the Alcatel 7301 ASAM into the

existing network.
