Abstract: Systems and methods are disclosed for unified systems of network tool optimizers (NTOs). A NTO supervisor device controls switch fabric circuitry to interconnect a plurality of NTO member devices so that packets received at a source port for one NTO member device can be output to a destination port for a different NTO member device. The NTO supervisor device is further configured to analyze filters for the NTO member devices and to generate filter rules for forwarding packets among the various NTO member devices using the switch fabric circuitry. Further, additional secondary NTO supervisor devices can also be included within the unified NTO system to further expand the system. As such, a plurality of NTO member devices are managed and controlled by one or more NTO supervisor devices to form a highly scalable and efficient unified NTO system.

Abstract: A method and system provides quality of service in a DSL network interfaced with the Internet. A connection engine determines whether a connection from an internet endpoint has an associated IP layer 3 quality of service or ATM layer 2 quality of service and provides the internet network quality of service parameters to a mapping engine. The mapping engine references a quality of service map to associate the layer 3 or layer 2 quality of service with a DSL layer 1 quality of service. The mapping engine provides the DSL quality of service parameters to the DSL network which establishes the DSL connection between a DSL endpoint and the internet endpoint with the appropriate quality of service. To provision services to a DSL network, the quality of service map is updated to associate quality of service parameters for the service, including its association with other network quality of service parameters.

Abstract: A system and method are provided for special signaling with customer premises equipment. The system includes loop termination equipment coupled to a local loop and comprising a signal generator. The system also includes customer premises equipment coupled to the local loop. The customer premises equipment and loop termination equipment are operable to communicate across a communication link established on the local loop. The loop termination equipment is further operable to control characteristics of a signal generated by the signal generator and to provide the signal to the customer premises equipment as special signaling where the signal has a frequency that does not substantially interfere with voice traffic on the local loop. The special signaling can be used to implement enhanced service to the customer premises including busy signal, queued data request processing, push data and telephony services.
