Description: A desired G.Bond port Data Rate in the downstream direction, in Kbps, to be achieved during initialization, under restrictions placed upon the member BCEs by their respective configuration settings. This object represents a sum of individual BCE downstream data rates, modified to compensate for fragmentation and encapsulation overhead (e.g. for an Ethernet service, the target data rate of 10Mbps SHALL allow lossless transmission of full-duplex 10Mbps Ethernet frame stream with minimal inter-frame gap). Note that the target downstream data rate may not be achieved during initialization (e.g. due to unavailability of required BCEs) or the initial bandwidth could deteriorate, so that the actual downstream data rate (sheGBondDownDataRate) could be less than sheGBondTargetDownDataRate.

The value between 1 and 1000000 indicates that the total downstream data rate of the G.Bond port after initialization SHALL be equal to the target data rate or less, if the target downstream data rate cannot be achieved under the restrictions configured for BCEs. In case the copper environment allows to achieve higher downstream data rate than that specified by this object, the excess capability SHALL be either converted to additional SNR margin or reclaimed by minimizing transmit power.

The value of 9999999 means that the target data rate is not fixed and SHALL be set to the maximum attainable rate during initialization (Best Effort), under specified spectral restrictions and with desired SNR Margin per BCE.

This object is valid for the -O subtype G.Bond ports and irrelevant for the -R subtypes.

Changing of the Target Downstream Data Rate MUST be performed when the link is Down. Attempts to change this object MUST be rejected (In case of SNMP with the error inconsistentValue), if the link is Up or Initializing.

This object MUST be maintained in a persistent manner.

NOTE: Not configurable for VDSL2 based GBOND interfaces.
