Patent number: 9484984Abstract: A device for managing signal transport, on a cable level, in a communication system, and a method for using same, are provided herein. The device is connectable between one or more access multiplexers (e.g., Very-high-speed Digital Subscriber Loop Access Multiplexer (VDSLAM) or a switch) and a cable in said communication system. The device includes: a plurality of access multiplexer-side transceivers connectable to access multiplexer-related physical medium, associated with said one or more access multiplexers; a plurality of customer-side transceivers connectable to respective customer-related wire pairs of said cable; and a processor connected to said access multiplexer-side transceivers and said customer-side transceivers, said processor comprising means for reducing crosstalk among said customer-related wire pairs. In some embodiments, vectoring is used for the crosstalk reduction, thus implementing a so-called cable level vectoring (CLV).Type: GrantFiled: December 23, 2012Date of Patent: November 1, 2016Assignee: ACTELIS NETWORKS (ISRAEL) INC.Inventors: Ioannis Kanellakopoulos, Amit Priebatch, Elad Domanovitz, Mauricio Nurko, Tuvia Barlev

Patent number: 8576899Abstract: A DSL communication system and a method for configuring a DSL communication system. The method includes training at least one anchor DSL modem transmitter to transmit information over at least one anchor line at an anchor bit rate that is determined based on an allowable tolerable noise level and a minimum allowable signal-to-noise ratio (SNR) margin; training one or more other DSL modem transmitter to transmit information over one or more other line at a bit rate that is determined by a current noise level and a target SNR margin, wherein the target SNR margin is higher than the minimum allowable SNR margin; and transmitting information by at least one trained DSL modem transmitter to at least one DSL modem receiver.Type: GrantFiled: August 19, 2009Date of Patent: November 5, 2013Assignee: Actelis Networks (Israel) Ltd.Inventors: Ioannis Kanellakopoulos, Amit Levy, Tuvia Barlev, Maya Bar-El, Amit Priebatch, Eitan Tsur

Patent number: 7453929Abstract: A system for transporting a high speed data stream over a plurality of relatively low bandwidth unshielded twisted copper pairs within the local loop plant or in any environment having a plurality of copper lines. A transmit data processor may perform scrambling, FEC encoding, and interleaving on the data before it is divided and dispatched to the plurality of modem elements for transmission over the local loop plant, either bidirectionally or unidirectionally. On the receiving side, the individual data streams are collected, aggregated, and a receive data processor performs de-interleaving, FEC decoding and de-interleaving, resulting in the high speed data stream originally transmitted. The system also may include crosstalk cancellation, power and PSD control, data raze control and optimal routing of the transmitted signals within the twisted pair binders. The system may optionally multiplex a plurality of low bandwidth telephony services over the high speed link using either TDM or FDM techniques.Type: GrantFiled: March 2, 2005Date of Patent: November 18, 2008Assignee: Actelis Networks Ltd.Inventors: Tuvia Barlev, Arkady Molev Shteiman, Ofer Sharon

Patent number: 7133441Abstract: A system for transporting a high speed data stream over a plurality of relatively low bandwidth unshielded twisted copper pairs within the local loop plant or in any environment having a plurality of copper lines, such as on campuses, within large buildings, etc. The copper twisted pairs are transformed from a plurality of low bandwidth, low reliability links into a high reliability, very high bandwidth long range communication channel utilizing optimized xDSL transmission technologies over the plurality of copper pairs. A transmit data processor perform scrambling, FEC encoding and interleaving on the data before it is divided and dispatched to the plurality of modem elements for transmission over the local loop plant, either bidirectionally or unidirectionally. On the receiving side, the individual data streams are collected, aggregated and a receive data processor performs de-interleaving, FEC decoding and de-interleaving, resulting in the high speed data stream originally transmitted.Type: GrantFiled: February 22, 2000Date of Patent: November 7, 2006Assignee: Actelis Networks Inc.Inventors: Tuvia Barlev, Arkady Molev Shtayman, Amir Kanchuk, Gilad Rozen, Ishai Ilani, Ofer Sharon, Robert Shilton
