Module: HUAWEI-VOP-MIB
OID (symbolic): HUAWEI-VOP-MIB::hwVOPVirtualNoiseConfProfTxRefVnUs
OID (numeric): 1.3.6.1.4.1.2011.6.144.1.1.18.1.5
Node type: OBJECT-TYPE
Type: Xdsl2LineTxRefVnUs
Access: read-create
Description: This configuration parameter defines the upstream transmitter referred virtual noise. The TXREFVNus shall be specified through a set of breakpoints. Each breakpoint shall consist of a subcarrier index t, with a subcarrier spacing of 4.3125 kHz, and a noise PSD level (expressed in dBm/Hz) at that subcarrier. The set of breakpoints can then be represented as: [(t1, PSD1), (t2, PSD2), ... , (tN, PSDN)]. 16 groups can be configured at most, and 3 bytes for each group. The first two bytes represent tone index, the 3th byte represents the configured PSD value. The relation between configured PSD value and real PSD value is: REAL PSD = (CONFIGURED PSD + 80) * (-0.5dBm/Hz).
What is hwVOPVirtualNoiseConfProfTxRefVnUs?
Upstream transmitter-referred virtual noise (TXREFVNus), specified as up to 16 breakpoints of (subcarrier index at 4.3125 kHz spacing, noise PSD in dBm/Hz), 3 bytes per breakpoint, with the same real-PSD conversion formula (configured value + 80) * -0.5 dBm/Hz (G.997.1 7.3.1.7.4); used only when hwVOPSNRMarginConfProfSnrModeUs enables virtual noise upstream.
