Patent number: 9215155Abstract: A method for selecting a mode of operation for at least two modems is described. First, a handshake procedure is performed in order to determine a set of possible modes of operation supported by said modems. From said set of possible modes of operation, a set of favorable modes of operation is derived. In case there exist two or more favorable modes of operation, a probing-based selection is performed that comprises evaluating respective performances of said favorable modes of operation. The favorable mode of operation with the best performance is selected as a resultant mode of operation.Type: GrantFiled: April 29, 2013Date of Patent: December 15, 2015Assignee: Broadcom CoporationInventors: Miguel Peeters, Raphael Cassiers, Benoit Christiaens, Ruben Lysens, Olivier Van De Wiel

Publication number: 20150138972Abstract: The present disclosure extends the flow control in a DSL communication system to include a remote back-pressure flow control within a DSL receiver of the DSL communication system. The remote back-pressure flow control can prevent a DSL transmitter of the DSL communication system from overwhelming the DSL receiver. The remote back-pressure flow control is implemented within a receiving network processor (rx-NP) of the DSL receiver to prevent the DSL transmitter from overwhelming the rx-NP.Type: ApplicationFiled: November 15, 2013Publication date: May 21, 2015Applicant: Broadcom CorporationInventors: Miguel PEETERS, Jean-Philippe Cornil, Eli Elmoalem, Lowell David Lamb, Benoit Christiaens

Patent number: 8898533Abstract: Embodiments described herein provide an apparatus for transmitting data in an xDSL. In one example, the apparatus can include a transmitter configured to transmit data over the xDSL system in the form of data transmission units (DTUs), the transmitter having a physical media specific-transmission convergence (PMS-TC) communication sublayer and a retransmission unit that is implemented in the PMS-TC sublayer, the retransmission unit including a retransmission buffer configured to store transmitted DTUs and to index the transmitted DTUs using retransmit containers, each retransmit container being defined as a time slot corresponding to a respective sent DTU. A retransmit request specifies a DTU by a corresponding retransmit container and wherein the retransmission unit is configured to retransmit the specified DTU in response to the retransmit request.Type: GrantFiled: February 14, 2013Date of Patent: November 25, 2014Assignee: Broadcom CorporationInventors: Benoit Christiaens, Miguel Peeters, Raphael Cassiers
