The present patent application is a Continuation of, and claims priority to and incorporates by reference, the corresponding U.S. patent application Ser. No. 11/345,215, entitled, “DSL System Training” filed on Feb. 1, 2006, and issued as U.S. Pat. No. 7,991,122 on Aug. 2, 2011, and claims priority to and incorporates by reference U.S. Provisional Patent Application No. 60/686,544 entitled “DSL System Training” filed on Jun. 2, 2005, and claims priority to and incorporates by reference U.S. Provisional Patent Application No. 60/698,113 entitled, “DSL System” filed on Jul. 10, 2005.
In one embodiment of the present invention, PSDMASK levels in all or a portion of the frequency band used for training a “new line” (that is, either a line that has never operated before or one for which operational information is missing or lost, also referred to as a “new user”) are set sufficiently low upon initial training, and the remaining already-operating lines (likely, but not necessarily in the same binder) are scanned for evidence of a faint but non-disruptive crosstalker (that is, the new line). The crosstalker/new line is assessed (for example, by a DSL Optimizer or controller), and then any vectored and/or non-vectored devices are updated appropriately before the new line is allowed to train at a higher signal level, for example to allow the new line to achieve a desired data rate. While existing standards (for example, but not limited to, the pending G.993.2 VDSL2 standard of the ITU) do not provide for such polite training, the present invention utilizes the fact that such politeness can instead be compelled via imposition of the PSDMASK (for example, by the service provider and/or a DSL optimizer) before the new line is allowed to train.
VDSL standards (including the existing G.993.1 VDSL1 and the emerging G.993.2 VDSL2 ITU standards) have made minimal provision for training of vectored lines and/or systems, other than providing means for all lines to use the same effective symbol clock and centralized control of the “timing advance.” This coordination of symbol clock and timing advance causes the interference among so-synchronized lines to occur independently on each and every tone (without interference from one tone of one user to any other tone of another user)—that is, each tone is independently modeled for all vectored lines as a matrix of signal flows from inputs on the particular tone to line outputs only on that same tone. The matrices for other tones are similar in structure but are independent. Thus, there is no crosstalk from tone n to tone m where n.noteq.m.
When upstream signal errors are large, then the calculation
X ^ u , n = 1 L ⁢ ∑ l = 1 L ⁢ E u , n ⁡ ( l ) T n ⁡ ( l ) Equation ⁢ ⁢ ( 1 )
averaged over a significant number of symbols (for example, L=40 or more) will be non-zero only if the new line has significant crosstalk into the line u on tone n. Another method to determine X is simply to use the values reported in any DSM-capable modem as described in the ATIS DSM Report. Furthermore, {circumflex over (X)}u,n will be the transfer function term needed to construct the matrix Hn used for vectoring. After estimating the vector channel, the vector system can be properly adjusted so that the new line does not cause any disruption to existing lines, even when a high level of power is used. A non-cooperative DSL might produce a larger error |Eu,n(I)|, but a zero {circumflex over (X)}u,n, because the signal from the non-cooperative DSL line will be uncorrelated with Tn(1). The non-cooperative crosstalker may thereafter be treated as noise. The set of tones on which Equation (1) is executed can be relatively small (or large), depending on existing knowledge of the binder and any applicable reliability constraints.
