Object
The upstream PSD mask applicable at the U-R2 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 16 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 9-47, which are
associated with a 16th breakpoint.
Each subcarrier index is an unsigned number in the range 0 and
NSCus-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 16, 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.
