摘要:
A method and a device for data processing in a digital subscriber line environment. A virtual noise level for a digital subscriber line is determined based on measurement information of at least one network element connected to the digital subscriber line.
摘要:
A method and a device for data processing. The data processing method utilizes at least two probing coefficients in a canceller and/or precompensator in combination with SNR feedback to process data in the canceller and/or in the precompensator.

摘要:
A method and a device for data processing in a digital subscriber line environment, wherein a flat noise margin is determined based on an actual noise determined and based on a maximum noise expected. A device is initialized using the flat noise margin. Also, a communication system is described that includes such a device.

A controller at a distribution point (DP) of a communication system is coupled to a plurality of customer premises (CP) transceivers via drop connections. The controller is configured to schedule upstream and downstream data transmissions across the drop connections such that they do not overlap from one drop connection to another thereby avoiding the effects of crosstalk. A flexible frame structure is used to permit dynamic scheduling changes. Overhead for the flexible frame structure is permitted to overlap on the drop connections, and a reduced bit loading is used to communicate the overhead relative to the bit loading used for data transmissions.
摘要:
Power dissipation within a network service unit, such as digital-subscriber-line access multiplexer (DSLAM), is treated as a resource that is to be shared among subscribers. In this regard, the total amount of available power dissipation is quantified, and the framing for the data streams communicated across the subscriber lines are controlled to ensure that specified power dissipation limits are not exceeded, accounting for one or more factors, such as traffic load, service level agreement (SLA) specifications, available power, and temperature.
