mask (in dBm/Hz) for exchanging based services,
used to modify parameter fmax, 0~255 represents
0~-127.5 dBm/Hz in steps of -0.5 dBm/Hz
fmin
: the minimum frequency from which DPBO
shall be applied, 0~2048 in 4.3125 kHz
fmax
: the maximum frequency at which DPBO may
be applied, 32~6956 in 4.3125 kHz
epsd
: sets Power Spectral Density (PSD) for PSD
toolbox or sets PSD ID to PSD toolbox
a pre-defined PSD mask to reduce interference
with other services (for example, ADSL) in the
same copper bundle.
tone
: the index of a tone, 1~512
psd
: Power Spectral Density, 0~255 represents
0~-127.5 dBm/Hz in steps of -0.5 dBm/Hz
psdid
: standard PSD shape ID for PSD toolbox
0=psd_co, 1=psd_flat, 2=psd_cab_ansi,

< svid > < spriority >
< cvid > < cpriority >
Sets/changes double-tagged VLAN settings on the
specified VDSL subscriber port(s).
svid
: The service provider VLAN ID.
spriority
: The service provider IEEE 802.1p
priority setting.
cvid
: The customer VLAN ID.
cpriority
: The customer IEEE 802.1p priority
setting.
