摘要： Residual FEXT resulting from intended and/or inherent partial cancellation of crosstalk in vectored DSL systems impairs upstream power back-off (UPBO) as traditionally implemented. By considering and taking into account the effects of residual crosstalk on vectored DSL system performance and operation, improved data rates and/or other vectored DSL system performance are realized through the use of UPBO parameters generated for a given residual FEXT environment.

摘要： Methods, systems, and devices are described for wired communication. A first distribution point uses sets of modems to communicate with a second distribution point over a crosstalk link to exchange information and coordinate the use of multiple sets of frequency bands. In some cases, the first distribution point may share a cable binder with the second distribution point and detect crosstalk on the subscriber lines in the cable binder. Based at least in part on the crosstalk detected by the first distribution point, the first and second distribution points may communicate over a crosstalk link between sets of lines in the binder. The distribution points may use one or more sets of predefined tones within the multiple sets of frequency bands to exchange messages, where the messages may include synchronization information, operating parameters, or control and data information.

摘要： Methods, systems, and devices are described for wired communication. In one aspect, a distribution point may use a redundant number of digital subscriber line (DSL) lines that share a same cable binder to cancel crosstalk. For example a first distribution point may use a redundant number of lines, which may be virtualized lines, to cancel interference between lines controlled by the first distribution point and lines controlled by a second distribution point. In some cases, a distribution point may share precoding and cancelling coefficients with another distribution point over a cloud network or other service to enable vectoring without sharing transmitted data between the two distribution points. That is, the first distribution point may receive information related to crosstalk between sets of CPEs without receiving data transmitted by a separate distribution point sharing the same cable binder, and use the crosstalk related information to cancel crosstalk.
