The first of a new class of broadband access systems, the CN 1000 Broadband Loop Carrier (BLC) offers service providers a cost-saving approach to broadband service delivery and prepares them to reap the full benefits of the emerging, packet-based public network.

CN 1000 BLC

The CN 1000 enables service providers to deploy integrated Plain Old Telephone Service (POTS) and Digital Subscriber Line (DSL) services to the mass-market—from both remote terminals and central offices. It enables providers to introduce new services, such as video, and to migrate gracefully from today’s circuit-switched public network to a converged, packet-based public network.

The Opportunity

As demand for bandwidth continues to grow, so will the opportunity for service providers to provide a range of revenue-generating voice and data services. Ultimately, all voice, data, and video traffic will travel over a single, packet-based public network, with broadband connections into every household. This full integration of data network and circuit-switched voice networks will enable service providers to reduce costs dramatically while increasing the speed of service delivery.

DSL is the most widely deployed residential broadband technology due to its ability to leverage prior investments in copper plant infrastructure. Nevertheless, the cost and complexity associated with its current deployment approach—which requires the overlay of data onto the narrowband voice network—is problematic. Service providers are being forced to manage two networks—one for voice, one for data—and they are struggling with the associated costly truck-rolls, and manual service activation.

The CN 1000 Broadband Loop Carrier

The CN 1000 Broadband Loop Carrier changes the economics of broadband deployment, enabling high volume delivery of POTS and DSL services to a service provider’s entire subscriber base. Innovative in its approach, the CN 1000 platform simplifies the access network by integrating voice, data, and video service capabilities on every line, dramatically reducing DSL capital and operational costs. In addition, it opens the door to integrated service provisioning by permitting a smooth migration from today’s TDM-based network to a converged, packet-based public network.

Video over ADSL

Introducing video to your data consumers is easy with multicast support and Ciena’s no truck-roll service provisioning. The CN 1000 provides on-board multicasting and IGMP processing to maintain efficient use of transport network resources. The CN 1000 draws on ATM point-to-multipoint multicasting to harness the QoS guarantees provided by ATM. The use of IGMP ensures interoperability with a wide range of third-party equipment, including set top boxes and video servers.
