Time-alignment of crosstalk acquisition phases between multiple joining lines

摘要

In an embodiment, the access node includes first and second transceiver units for initializing first and second communication channels, respectively, over first and second communication lines, respectively. The initialization of the first and second communication channels respectively including first and second handshake phases wherein peer transceiver units exchange capabilities and select (i) a common mode of operation, (ii) first and second crosstalk channel acquisition phases from the first and second communication lines, and (iii) first and second generic initialization phases. The access node further includes a line initialization controller configured to stretch the execution of the first handshake phase with respect to the execution of the second handshake phase so as to shorten a time difference between respective entries into the first and second crosstalk channel acquisition phases.

1. An access node for providing broadband communication services to subscribers, and comprising a first transceiver unit for initializing a first communication channel over a first communication line and a second transceiver unit for subsequently initializing a second communication channel over a second communication line, which initialization of said first and second communication channels respectively comprising first and second handshake phases whereby peer transceiver units exchange capabilities and select a common mode of operation, first and second crosstalk channel acquisition phases from said first and second communication lines into further active communication lines, and further first and second generic initialization phases, wherein said access node further comprises a line initialization controller configured to stretch the execution of said first handshake phase with respect to the execution of said second handshake phase so as to shorten a time difference between respective entries into said first and second crosstalk channel acquisition phases.
