MULTI-OPERATOR VECTORING IN DIGITAL SUBSCRIBER LINE MODEMS

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.
