摘要:
Mechanisms for providing a subscriber-side interface with a passive optical network are described herein. An optical network termination (ONT) having an integrated broadband passive optical network processor is utilized to receive downstream data from an optical line termination (OLT) via a passive optical network and provide the contents of the downstream data to one or more subscriber devices via one or more data interfaces. Similarly, the ONT is adapted to receive and transmit upstream data from the one or more subscriber devices to the OLT via the passive optical network. The ONT preferably implements one or burst buffers for buffering upstream and/or downstream data. The ONT can be adapted to notify the OLT of the status of the burst buffer, thereby allowing the OLT to modify the bandwidth allocations.

Systems and methods for improving the quality of service associated with asymmetric digital subscriber line (ADSL) services are disclosed. Such improvements allow for the optimization of service levels and reliability in providing video and data services to subscribers, and in ensuring that such service levels remain acceptable as the number of subscribers on a given loop plant increase.

Similarly, the ONT is adapted to receive and transmit upstream data from the one or more subscriber devices to the OLT via the passive optical network. The ONT preferably implements one or more encryption/decryption mechanisms, such as the digital encryption standard (DES), to provide data protection in addition to, or in place of, data churning provided for by the ITU G.983 recommendations.

Resident activities and/or activity schedules are used to control a home management system. Resident activities and/or activity schedules may be monitored using a calendar application. A common repository may be provided for storing residential information used by multiple applications. Control of the home management system may include the selection of advertising video clips that may replace commercial advertisements in a vide stream. Advertising portions of a video stream may also be replaced with a locally generated video insertion. An architecture and/or system for home management is also provided.

An xDSL modem having an adaptive hybrid termination impedance. The modem has a transformer with two cores, one connected to the modem's receiver and the other connected to the modem's transmitter. The two cores share an adjustable termination impedance. The modem determines which impedance setting to use, based on one or more measurements of channel loss, local echo power and received power from the far end transmitter, and the like.
