Systems and methods are described for providing a plurality of communication services over existing access lines such as twisted pair access lines. These services include voice, audio/video, and data communication services, the so-called 'triple play' of services. The use of existing communication lines enables these services to be provided at a relatively low cost. Remote terminals are located close to subscriber premises to reduce the length of the existing communication lines connecting subscribers to the network. Data associated with a plurality of communication services may be statistically multiplexed onto the communication lines. Subscribers are provided with the capability to dynamically select services, including the capability to select audio/video signals from a set containing audio/video broadcast signals. The systems and methods enable data to be transported efficiently through the backbone network interconnecting central offices. Capabilities comparable the capabilities of coaxial cable systems are provided at a lower cost than alternative approaches, such as running fiber all the way to the subscriber premises.

Systems and methods for providing multiple communication services over existing twisted pair access lines

A system and method is described for providing communication services, including voice communications, data communications, audio/video-on-demand, and broadcast audio/video, over twisted-pair telephone lines. The system and method are based on broadband transmission techniques, such as fiber-to-the-neighborhood (FTTN) and digital subscriber line (DSL) techniques. This approach can be applied to develop an access network comprising an array of remote terminals connected to one or more telephone central offices by fiber optic cables and connected to subscriber nodes by twisted-pair lines. Each remote terminal has the capacity to support multiple subscribers and to switch broadcast channels onto subscriber lines. Each subscriber is provided the capability to individually select via the DSL interface one or more a broadcast channels from a larger set of channels.

Systems and methods for providing communication services over telephone lines

Systems and methods are described for forming and operating communication networks that support the needs of an enterprise. These systems and methods include: establishing a plurality enterprise network nodes overlaid on one or more common carrier networks; establishing independence between the enterprise network and the common carrier networks; designing services provided by the enterprise network to be consistent with the current modes of operation of the common carrier networks and employing existing services of the common carrier networks to transport enterprise data; employing redundancy in communications among enterprise network nodes and in the storage of enterprise data. Compared to current enterprise networks, a network based on these methods and systems is easier to implement, is less expensive, and could be deployed more quickly. This network is not limited by the coverage and services provided by any particular carrier. With the systems and methods of this invention, the impact on the common carrier networks of providing services for an enterprise network are minimized. The redundancy associated with the systems and methods of this invention enables an enterprise network to quickly recover from a disaster and support the continuity of business operations.

A networking approach is disclosed that combines the advantages of circuit switching and packet switching in an integrated communications network. With this approach, control signals are separated from the data and transmitted separately in a common control channel. Control and signaling operation can be viewed as a logical extension of generalized multi-protocol label switching (GMPLS). A variable number of data channels are dynamically assigned to each connection through the network. Channels are quickly switched in to accommodate the data flow through a connection and switched out when they are no longer needed. With this dynamic channel switching approach, a continuous data stream is not altered as it transverses the network and data channels are efficiently utilized even if the data source is bursty. The proposed approach is compatible with legacy networks and can provide a mechanism for convergence of circuit switching and packet switching. Most of the benefit of the proposed approach can be achieved with modifying only network and server equipment, but not necessarily client equipment, to support dynamic channel switching.

Wide area multi-service communications network based on dynamic channel switching

Methods are provided for forming and operating mesh communications networks. A primary application of these methods would be for a network for interconnecting telephone central offices. Compared to current networks, a network based on these methods may provide higher resource utilization efficiency, greater provisioning flexibility, and robustness against a wider range of network failures. These methods may enable protection and restoration of service following a failure to be tailored to the requirements of particular data flows. Mesh networks based on these methods of this invention may be extended seamlessly across contiguous LATA so that the data flow between central offices in different LATAs would not need to be routed through a separate inter-LATA network and would not require long haul transmission lines.
