Alcatel-Lucent 7330 ISAM FTTN
required on the aggregation switch.
The result is a cost-efficient and
gradual evolu tion 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
distrib uted access platform is that it
optimizes your network man agement
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
