efmCuAdaptiveSpectra
Module: EFM-CU-MIB
OID (symbolic): EFM-CU-MIB::efmCuAdaptiveSpectra
OID (numeric): 1.3.6.1.2.1.167.1.1.1.1.6
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: Indicates how to utilize excess capacity when the copper environment allows a higher total data rate to be achieved than that specified by the efmCuTargetDataRate.
A value of true(1) indicates that the excess capability SHALL be reclaimed by minimizing transmit power, e.g., using higher constellations and Power Back-Off, in order to reduce interference to other copper pairs in the binder and the adverse impact to link/system performance.
A value of false(2) indicates that the excess capability SHALL be converted to additional SNR margin and spread evenly across all active PMEs assigned to the (PCS) port, to increase link robustness.
This object is read-write for the -O subtype EFMCu ports (2BaseTL-O/10PassTS-O) and not available for the -R subtypes.
Changing of this object 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.
What is efmCuAdaptiveSpectra?
This read-write boolean decides what happens with extra capacity when the copper line can support a higher rate than efmCuTargetDataRate calls for: true means the port reduces transmit power to cut interference with neighboring pairs, false means it converts the surplus into additional SNR margin for more robustness. It must be changed while the link is down since it affects initialization behavior. An admin managing crosstalk in a dense cable bundle would set this to true.
