Embodiment Construction

[0056] figure 1 Frame n and frame n+1 are shown sent from a first network component to at least one second network component via different lines - line 1 , line 2 , line 3 and line 4 - during time t.

[0057] Preferably, the first network element is an exchange or a digital subscriber line access multiplexer CO / DSLAM, and the at least one second network element may be several customer premises equipment, each connected to one of the lines Line 1 to Line 4 .

[0058] An exchange or a digital subscriber line access multiplexer CO / DSLAM and several customer premises equipment may be connected via lines 1 to 4 by, for example, multi-core cables which may subject adjacent lines to crosstalk effects and / or interference.

[0059] via figure 1 The data transmitted by each of the lines shown also includes redundant information that can be used by the receiver to reconstruct the transmitted data in the event of an error that might have occurred on the line during data transmission.

Abstract

A method and a device for data processing are provided the method comprising the steps of (i) data is sent from a first network component to an at least one second network component via at least two lines; and (ii) the first network component transmits a measurement tag via at least one line of the at least two lines.

Description

technical field [0001] The invention relates to a method and a device for processing data, and to a communication system comprising the device. Background technique [0002] DSL or xDSL is a class of technologies that provide digital data transmission over the lines of the local telephone network. [0003] Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than conventional voice-band modems are capable of providing. This rapid transmission is achieved by employing frequencies not normally used by voice telephone calls, especially frequencies above normal human hearing. [0004] VDSL (Very High Speed ​​DSL) is an xDSL technology that provides faster data transmission over a single twisted pair. High bit rates are achieved over a range of approximately 300 meters (1000 feet), allowing 26 Mbit / s for symmetric access, or up to 52 Mbit / s downstream - up to 12 Mbit / s upst...
