Abstract
Embodiments of a method and a device are disclosed. A method for performing operations in a communications network is disclosed. The method involves, determining, at a first network node in a communications network, that a DSP of a receiver of a network node in the communications network can operate at a reduced functionality level, and communicating the determination from the first network node to a second network node in the communications network in a protocol data unit (PDU), wherein the DSP of a receiver of a network node that can operate at a reduced functionality level is a DSP of a receiver of one of the first network node and the second network node.

A method for performing operations in a communications network, the method comprising:
- determining, at a first network node in a communications network, that a digital signal processor (DSP) of a receiver of either the first network node or a second network node in the communications network can operate at a reduced functionality level;
- and
- communicating the determination from the first network node to the second network node in the communications network in a protocol data unit (PDU) via a communications channel between the first network node and the second network node;
- further comprising:
- determining a value of a DSP parameter for the receiver of the second network node;
- embedding the value of the DSP parameter into a PDU;
- and
- transmitting the PDU from the first network node to the second network node in the communications network via the communications channel between the first network node and the second network node;
- wherein embedding the value of the DSP parameter into the PDU comprises embedding the value of the DSP parameter into a header field of the PDU.
A physical layer (PHY) device for a first network node in a communications network, the PHY device comprising:
- a transmitter;
- a receiver that includes a digital signal processor (DSP);
- and
- control logic configured to determine that either the DSP of the receiver of the PHY device for the first network node or a DSP of a receiver of a PHY device for a second network node in the communications network can operate at a reduced functionality level and to communicate the determination to the second network node in the communications network in a protocol data unit (PDU) via a communications channel between the first network node and the second network node;
- wherein:
- the transmitter of the PHY device for the first network node is configured to embed a value of a DSP parameter into a header of a PDU and to embed an operations, administration, and management (OAM) word into the PDU, wherein the OAM word includes information related to the value of the DSP parameter;
- and
- the receiver of the PHY device for the first network node is configured to extract a value of a DSP parameter from a header of a received PDU and to extract an OAM word from the received PDU, wherein the OAM word includes information related to the value of the DSP parameter.
A method for performing operations in a communications network, the method comprising:
- determining, at a first network node in a communications network, that a digital signal processor (DSP) of a receiver of either the first network node or a second network node in the communications network can operate at a reduced functionality level;
- and
- communicating the determination from the first network node to the second network node in the communications network in a protocol data unit (PDU) via a communications channel between the first network node and the second network node, wherein communicating the determination from the first network node to the second network node comprises embedding an operations, administration, and management (OAM) word into a payload field of the PDU at a physical coding sublayer transmitter (PCS-TX) of the first network node.
