The Alcatel-Lucent 7330 Intelligent Services Access Manager (ISAM)
Fiber-to-the-Node (FTTN) takes the best of Alcatel-Lucent’s DSL
developments, and provides a unique set of capabilities that enables
you to deliver the most competitive triple play service offerings. Building
on Alcatel-Lucent’s leadership in broadband access, the Alcatel-Lucent
7330 ISAM FTTN addresses your growing requirement for a deep-fiber
access solution. This innovative platform enables you to offer IPTV and
other ultra-high bandwidth applications while leveraging your existing
copper plant. As a member of the ISAM family, the Alcatel-Lucent
7330 ISAM FTTN shares technology with the Alcatel-Lucent 7302 ISAM,
the industry’s first IP-based platform capable of delivering 100-percent
triple play services.

The Alcatel-Lucent Fiber-to-the-Node
Solution for Deep-Fiber Access
Power and Flexibility
for Your Unique Needs
Alcatel-Lucent has been the world
leader in DSL deployments since
the early development of the tech-
nology. To date, Alcatel-Lucent has
shipped more than 143 million DSL
lines worldwide.
Market requirements for bandwidth
to the subscriber have increased
tremendously since the initial
deployments of DSL services. Each
change in market demand has been
anticipated and met with a new
technological breakthrough from
Alcatel-Lucent. The Alcatel-Lucent
7330 ISAM FTTN is part of Alcatel-
Lucent’s continued worldwide lead-
ership in broadband innovation.
To meet the challenge of bringing
more bandwidth closer to the sub-
scriber, many of you are already
deploying the next wave of DSL
deployments by increasing fiber
penetration in your access networks.
This new deep-fiber access delivers
non-blocking, ultra-high bandwidth
to each subscriber, enabling the deliv-
ery of rich communication and
entertainment services. Indeed, as
an evolutionary step toward a full
fiber network, FTTN provides the
most competitive service.

So, if you are a telecom service
provider, you will need to offer bun-
dled services that typically include IP
television (IPTV), as well as other
interactive services - in addition to
high-speed Internet (HSI) and voice.
The combination of IP services need-
ed to meet this strategic requirement
can increase the required bandwidth
to the subscriber from 2 or 3 Mb/s to
20 Mb/s, or more. With Alcatel-
Lucent’s VDSL2, 20 Mb/s can be
delivered simultaneously to each port.
Moreover, greater bandwidths on indi-
vidual ports can also be delivered
depending on total system load and
loop lengths. Just as important, the
ability to bond allows more bandwidth
for customers deeper into the network.
Your challenge, put simply, is to pro-
vide additional subscriber bandwidth –
cost-effectively and efficiently.

Taking the Battle to a New Level
Halting the Siege
If you are a traditional ILEC service
provider, you are likely under siege.
Cable operators have attacked you
in the broadband and voice market.
By offering voice services, they have
begun to capture voice customers at
an accelerating rate. Competitive
local exchange carriers (CLECs) are
continuing to be a major factor, too.
So, in order to compete, you need to
take the battle to a new level and
introduce new technologies.
Broadband technology, and the many
IP services that it enables, are creating
a new battleground. Those companies
that deploy high-bandwidth connec-
tivity to the customer and effectively
develop and market IP services will
win the war.
IP services in the home are the
key to winning the battle against
your competition.

Alcatel-Lucent 7330 ISAM FTTN
The good news is that FTTN economically increases the
available bandwidth to the subscriber while leveraging the
existing copper plant to keep costs down.
Technological Hurdles
The existing DSL network was engineered to provide
HSI access with downstream bandwidth between 0.5
and 2 Mb/s. Competition and increasing usage of the
broadband connection have driven HSI bandwidth
requirements into the 3 to 8 Mb/s range. However, the
deployment of IPTV service calls for a deep-fiber solution
in the access network. Bandwidth requirements for a
competitive triple play service require 20 Mb/s or more.

FTTN Leverages the Existing
Copper Infrastructure
For many customers, the long-term solution is to deploy fiber-to-the-user
(FTTU). This will enable the delivery of virtually unlimited subscriber
bandwidth. While this solution is available today and practical in many
cases, time-to-market and short-term economic pressures are driving a more
incremental access strategy — FTTN. As illustrated in Figure, 1, by leveraging
the existing copper infrastructure and by deploying fiber deep in the outside
plant, FTTN reduces copper loop lengths, cuts trench costs, and increases
bandwidth with DSL.
As a member of the ISAM family, the Alcatel-Lucent 7330 ISAM FTTN
delivers a full suite of triple-play services to all customers regardless of the
population density and central office (CO) reach. Designed to be flexible and
standards-based, the Alcatel-Lucent 7330 ISAM FTTN assures simplified oper-
ations, minimized operating expenditures (OPEX), less training requirements,
and faster time-to-market for new services.

required on the aggregation switch.
The result is a cost-efficient and
gradual evolution toward deep-fiber
penetration.
As a service provider, migrating your
voice services to new VoIP (Voice
over Internet Protocol)/IMS (Internet
Protocol Multimedia Subsystem)-
based network architectures becomes
a vital part of your network transfor-
mation. Voice transformation to VoIP
has already started in the home with
ATAs (analog terminal adapters).
FTTN allows you to broaden that net-
work path by offering integrated ATA
devices in the DSL modems. These
are commonly called Residential
Gateways (RGs). With this transfor-
mation in mind, Alcatel-Lucent also
offers a POTS line termination card
for those customers that may be left
on your traditional voice network but
have not chosen to upgrade to newer
DSL-based services. The POLT card
allows you to convert those remaining
customers to an IMS-based network.
An additional advantage of this
distributed access platform is that it
optimizes your network management
because the distributed system is
viewed as one node.
Indeed, FTTN networks have several
key advantages, including:
• Triple play service capabilities
• Small footprint and minimal
power requirements
• An incremental step toward
FTTU enabled by an investment
in deep fiber
• Seamless integration into existing
operations processes, reducing
training costs
• Accelerated deployment, reducing
costs and time-to-market while
increasing revenues
• Allowing the migration of voice
services to new IMS-based
architectures
The Alcatel-Lucent 7330 ISAM
FTTN is capable of various forms of
expansion that utilize the switching
fabric and network uplinks of the host
shelf. As a result, you can extend the
host shelf in a distributed way, opti-
mizing the network infrastructure and
reducing the number of fiber connec-
tions to the CO. This optimization of
the fiber connectivity is what provides
the self-aggregation concept that
allows reuse of the host shelf resources.
This expansion capability provides
increased coverage and better utiliza-
tion of the bandwidth. Fewer fiber
connections means fewer ports

FTTN — World-Class Technology
for World-Class Solutions
The Alcatel-Lucent 7330 ISAM FTTN builds on Alcatel-
Lucent’s worldwide DSL expertise by integrating the best
technology available from the Alcatel-Lucent 7302 ISAM
into a more compact remote digital subscriber line access
multiplexer (DSLAM), which is tailored for the unique
requirements of FTTN networks.
Figure 2 illustrates an Alcatel-Lucent 7330 ISAM FTTN
network layout, depicting a standard service provider
coverage area. In the CO, the Alcatel-Lucent 7330 ISAM
FTTN host shelf is being used to serve lines that are within
the CO’s serving area distance. At one remote site, a remote
host is connected to an Alcatel-Lucent 7330 ISAM FTTN
expansion shelf (ES) while at another remote site, a sealed
expansion module (SEM) is being used. This extends your
serving area in a cost-efficient way, allowing modular
growth and the quick deployment of new services. Moreover,
the host shelf can be extended with an Alcatel-Lucent
7330 ISAM FTTN ES or SEM.

Key features of the Alcatel-Lucent 7330 ISAM FTTN
host shelf include:
• High-capacity 24-Gb/s switching fabric and LT
architecture, providing non-blocking service to all
subscribers at ADSL2plus and VDSL2 rates
• Up to eight GigE uplinks, supporting service provider
migration toward Ethernet managed area networks
(EMANs) for DSL aggregation
• Up to twelve GigE expansion links for connecting
expansion modules
• Up to four LT cards and four POTS splitter card slots
to support up to 192 DSL ports
• Integration with Alcatel-Lucent 5526 AMS, in-band
