SYNTAX Xdsl2PsdMaskDs
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The downstream PSD mask applicable at the U-C2 reference
point.
This parameter is used only for G.992.5 and it may impose PSD
restrictions (breakpoints) in addition to the Limit PSD mask
defined in G.992.5.
This is a string of 32 pairs of values in the following
structure:
Octets 0-1 - Index of the first subcarrier used in the context of
a first breakpoint.
Octet 2 - The PSD reduction for the subcarrier indicated in
octets 0 and 1.
Octets 3-5 - Same, for a second breakpoint.
Octets 6-8 - Same, for a third breakpoint.
This architecture continues until octets 94-95, which are
associated with a 32nd breakpoint.
Each subcarrier index is an unsigned number in the range 0 and
NSCds-1. Each PSD reduction value is in the range 0 (0 dBm/Hz) to
255 (-127.5 dBm/Hz) with steps of 0.5 dBm/Hz. Valid values are in
the range 0 to 190 (0 to -95 dBm/Hz).
When the number of breakpoints is less than 32, all remaining
octets are set to the value '0'. Note that the content of this
object should be correlated with the subcarrier mask and with
the RFI setup."
