Service providers are faced with optimizing their existing network infrastructure to support advanced services, enabling not only voice and simple broadband access, but newer services like IPTV. Historically, wireline services have been delivered across disparate networks, each with its own infrastructure and expense. However, the maturation of industry standards related to IP is enabling the convergence of these disparate networks across a unified network architecture. Reconciling existing broadband network assets with the need to invest in next-generation packet systems is a balancing act for service providers.

ADTRAN understands the operational environment of our customers and the need to develop asset transition strategies rather than wholesale asset replacements. New packet infrastructures are needed to deliver on the promise of a unified broadband network. With tremendous OPEX and CAPEX savings, the scalability and flexibility of ADTRAN's broadband access solutions are ideally suited to facilitate the migration from circuit to packet.

How will broadband access services be delivered in the future? Copper or fiber? What's the right architecture? Fiber to the node (FTTN) or premises (FTTP)? Today's access systems must accommodate a variety of deployment situations and integrate multiple technologies into a common, unified architecture for service delivery. ADTRAN's Total Access Systems are designed with that purpose in mind.
