Method for managing data transport using crosstalk data
A method and device are provided for affecting data conveyance within a cable comprising a plurality of copper wire lines. The method comprises: providing information about crosstalk interference experienced by the copper wire lines; for each copper wire line experiencing crosstalk interference (interfered line), identifying which other copper wire lines induce crosstalk interference to that interfered line; partitioning the copper wire lines into interference groups, where each interference group comprises at least one copper wire line, wherein at least one of the interference groups comprises at least three copper wire lines, and wherein in case that a given interference group comprises more than two copper wire lines, then each of the copper wire lines belonging to that interference group is subjected to interference induced by another copper wire line that belongs to that interference group; and based on the partitioning step, changing operational settings of at least one copper wire line.

providing information which relates to crosstalk interference experienced by each of the plurality of copper wire lines;
for each of the plurality of copper wire lines experiencing crosstalk interference, thus being an interfered line, identifying which of the other copper wire lines comprised in the plurality of copper wire lines, induce crosstalk interference to the respective interfered line;
partitioning the plurality of copper wire lines into a plurality of interference groups, wherein each of the interference groups comprises at least one copper wire line, wherein at least one of the interference groups comprises at least three copper wire lines, and wherein in case a given interference group comprises more than two copper wire lines, then each of the copper wire lines belonging to that given interference group is subjected to interference induced by at least one other copper wire line that belongs to that very same interference group;
based on the partitioning of the plurality of copper wire lines into a plurality of interference groups, changing operational settings of at least one of the plurality of copper wire lines comprised in the communication cable, thereby affecting the conveyance of data along the communication cable; and
wherein said method further comprising a step of selecting one or more interference groups from among the plurality of interference groups, wherein the number of the selected interference groups is less than or equal to the number of interference groups included in the plurality of interference groups, and wherein the step of changing operational settings of at least one of the plurality of copper wire lines comprised in the communication cable is carried out based on information which relates to the selected interference groups.
2. The method of claim 1 , wherein the step of providing information which relates to crosstalk interference experienced by each one of the plurality of copper wire lines, further comprises determining for any given one of the plurality of copper wire lines, whether at least one of its interfering copper wire lines induces crosstalk interference at a level that exceeds a pre-defined threshold.
3. The method of claim 2 , wherein in case that none of the interfering copper wire lines induces crosstalk interference to said given copper wire line at a level that exceeds said pre-defined threshold, determining that said given copper wire line will be included in an interference group that does not include any other copper wire line.
4. The method of claim 1 , wherein in case that a given interference group comprises more than two copper wire lines, all the copper wire lines that induce interference to any given copper wire line belonging to said interference group, also will be included in said interference group.
5. The method of claim 1 , wherein said communication cable is a Digital Subscriber Line (“DSL”) cable comprising several binders, and wherein each binder comprises a plurality of copper wire lines, and wherein no knowledge on the arrangement of said plurality of copper wire lines within said communication cable is known prior to implementing said method.
6. The method according to claim 1 , wherein the criterion for selecting the one or more interference groups from among the plurality of interference groups is performance degradation within a certain interference group and/or correlated errors between members of the group.
7. The method of claim 1 , further comprising a step of assigning to each copper wire line an ID number associated with the respective interference group to which it is associated.
8. device operative to adjust setting for conveying data in one or more copper wire lines extending within a Digital Subscriber Line (DSL) cable which comprises a plurality of copper wire lines, the device comprising a processor adapted to:
receive information that relates to interference experienced by each copper wire line of the plurality of copper wire lines;
identify, for each copper wire line that is being interfered, which one or more copper wire lines induce interference thereto;
partition the plurality of copper wire lines into a plurality of interference groups, wherein each of the interference groups comprises at least one copper wire line, wherein at least one of the interference groups comprises at least three copper wire lines, and wherein in case that a given interference group comprises more than two copper wire lines, then each of the copper wire lines belonging to that given interference group is subjected to interference induced by at least one other copper wire line that belongs to that very same interference group;
adjust operational settings in at least one copper wire line, based on the division of the plurality of copper wire lines into a plurality of interference groups; and
wherein said processor is further operative to select one or more interference groups from among the plurality of interference groups, wherein the number of the selected interference groups is less than or equal to the number of interference groups included in the plurality of interference groups, and wherein the processor is further operative to apply the selected interference groups for adjust operational settings of at least one of the copper wire lines for conveying of data along the communication cable.
9. The device of claim 8 , wherein said processor is adapted to receive information which relates to crosstalk interference experienced by each one of the plurality of copper wire lines, and to determine for any given one of the plurality of copper wire lines, whether at least one of its interfering copper wire lines induces crosstalk interference at a level that exceeds a pre-defined threshold.
10. The device of claim 9 , wherein the processor is operative to include said given copper wire line in an interference group that does not include any other copper wire line, in case that none of the interfering copper wire lines induces crosstalk interference to said given copper wire line at a level that exceeds a pre-defined threshold.
11. The device of claim 8 , wherein in case that a given interference group comprises more than two copper wire lines, the processor is adapted to include all the copper wire lines that induce interference to a given copper wire line of that interference group, at said given interference group.
12. The device according to claim 8 , wherein the selecting of one or more interference groups from among the plurality of interference groups is based on detecting performance degradation within an interference group and/or correlated errors between members of such a group.
