DESCRIPTION
Configures the upstream virtual noise PSD level by defining the
break points (used for VDSL2 protocol).
carrier-index: 0-4095
vn-psd: 0-200 or 255. 0 = -140dBm/Hz,-200 = -40 dBm/Hz in
steps of 0.5 dBm/Hz, 255 = 0 W/Hz
Disables the downstream PSD mask.
Disables the upstream PSD mask.
Configures Downstream Power Back Off (DPBO) E-side Cable
Model (ESCM) parameter A (used for VDSL2 protocol).
escm-a: 0-640. 0: -1, 640: 1.5 in steps of 2^-8
default: 256
Configures DPBO E-side Cable Model (ESCM) parameter B (used
for VDSL2 protocol).
escm-b: 0-640. 0: -1, 640: 1.5 in steps of 2^-8
default: 512
Configures DPBO E-side Cable Model (ESCM) parameter C (used
for VDSL2 protocol).
escm-c: 0-640. 0: -1, 640: 1.5 in steps of 2^-8
default: 256
Configures DPBO E-side cable Electrical Length (used for VDSL2
protocol).
esel: 0-511. 0: 0dB, 511: 255.5dB in steps of 0.5 dB
default: 0
Configures the DPBO Minimum Usable received PSD mask (used
for VDSL2 protocol).
mus: 0-255. 0: 0dBm/Hz, 255: -127.5dBm/Hz in steps of -0.5
dBm/Hz
default: 180
Configures the DPBO maximum frequency (used for VDSL2
protocol).
fmax: 32-6959. 32: 138 KHz, 6959: 30010 KHz in steps of 4.3125
KHz
default: 512
Configures the DPBO minimum frequency (used for VDSL2
protocol).

default: 32
Configures the DPBO PSD mask used at exchange (used for
VDSL2 protocol).
carrier-index: 0-4095
epsd: 0-190. scalar value 0--95dBm in steps of -0.5dBm
