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

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.
