A centralized dynamic resource allocation is suggested to adjust a resource allocation for at least two DPUs. Also, a method for adjusting a resource allocation for the at least two DPUs by a centralized dynamic resource allocation entity is provided. Further, a system comprising at least one such device is proposed.

Coordination of DPUs in a crosstalk environment

Methods, systems, and computer readable medium for initializing communication for multiple transceivers. In one aspect, a method includes launching an initialization process of a first transceiver. The initialization process includes obtaining, for a second transceiver, a set of handshake information and inserting the set of handshake information of the second transceiver into one or more registers that are transmitted with first handshake information of the first transceiver during initialization of the first transceiver. The initialization process includes initiating a communications channel for the second transceiver over the same physical communications medium using the set of handshake information that was inserted into the one or more registers, including transmitting, by the first transceiver, the first handshake information of the first transceiver together with the set of handshake information for the second transceiver over the same physical communications medium using the given set of tones.

Initializing communication for multiple transceivers

Methods, systems, and apparatus for crosstalk avoidance in a telecommunications network are disclosed. In one aspect a telecommunications device includes a transceiver and a vectoring engine coupled to the transceiver. The vectoring engine can include a vectoring processor and vectoring control entity (e.g., apparatus). The vectoring engine is configured to instruct the transceiver to transmit, over a given line pair of a given vectoring group, initialization symbols at one or more configurable locations of a Time-Division Duplex (TDD) frame. For example, the vectoring engine can instruct the transceiver to transmit the initialization symbols beginning at a first symbol time following transmission, over other line pairs of the given vectoring group, of a Robust Management Channel (RMC) symbol.
