摘要： Systems and methods for characterizing loops based on frequency domain reflectometry single-ended line testing (FDR-SELT) are described. One embodiment includes a method for determining whether a straight-loop departure condition exists on a loop under test. First, an un-calibrated echo signal is received. A region associated with the loop under test, a platform type, and estimated the length of the loop under test are then used together with the received un-calibrated echo signal to determine whether the loop is not a straight loop is determined through determining whether at least one differentiating feature is present in the received signal. Another embodiment includes a method for determining a loop gauge for a loop under test through analyzing characteristics relating to local maxima and local minima of the received un-calibrated echo signal using the region, platform type, and the estimated loop length.

摘要： Systems and methods for protecting DSL systems against impulse noise are provided. Disclosed herein are example embodiments of a retransmission technique located above the gamma interface (i.e., in the network processing layer). Such a retransmission technique can be combined with standard RS coding with standard erasure-decoding & triangular interleaving at the PMS-TC layer. Example embodiments of the technique involve using the RS code to protect against REIN noise, and using γ-layer retransmission for protecting against error events not corrected by the RS code, e.g. a SHINE noise in the presence of REIN. Both techniques are used jointly in the case of combined REIN and SHINE noise.

摘要： Crosstalk interference induced by the adjacent pairs is one of the major performance limiting factors of DSL systems. As there is a rapid increase in the deployment of DSL services worldwide, the need to provide information about noise related parameters to the operators and the service providers is of utmost importance. Satisfying such a need enables operators to anticipate the line capacity and understand the noise level characteristics of the loop environment. Specifically, crosstalk and more particularly upstream near end crosstalk (NEXT) in the presence of narrowband interference can be classified to isolate the particular service type causing the upstream NEXT. The identification of the service type of the upstream NEXT would enable operators to address the disturber.
摘要翻译：由相邻对引起的串扰干扰是DSL系统的主要性能限制因素之一。随着全球DSL服务部署的快速增长，向运营商和服务提供商提供有关噪声相关参数的信息的需求至关重要。满足这样的需求使操作员能够预测线路容量并了解环路环境的噪声水平特性。具体地说，在存在窄带干扰的情况下，串扰，尤其是上游近端串扰（NEXT）可以被分类以隔离导致上游NEXT的特定服务类型。识别上游NEXT的服务类型将使运营商能够解决干扰。

摘要： A method and system of the present inventions reduces both near-end crosstalk (NEXT) and far-end crosstalk (FEXT) interferences due to handshake tones into upstream and downstream neighboring services, both at the customer premises equipment (CPE) and at the central office (CO), when handshake is experienced. An embodiment of the present inventions is directed to significantly reduce the NEXT and/or FEXT interferences due to handshake tones. For example, NEXT and/or FEXT interferences due to G.994.1 handshake tones, identified as, bins 7 and 9 for the Upstream channel and bins 12, 14 and 64 for the Downstream channel may be reduced. An embodiment of the present inventions provides an algorithm that may be used for both NEXT and FEXT Handshake Interferences reduction at the CO and at the CPE. In addition, the algorithm may operate in the time domain and in the frequency domain. Frequency domain algorithm offers two options, both versions taking advantage of the high correlation time of the Handshake tone signals.
