A profile is activated by setting this object to 'active'.
Before a profile can be deleted or taken out of service (by
setting this object to 'destroy' or 'notInService'), it MUST be
first unreferenced from all templates.
A row in this table is said to be unreferenced when there is no
instance of xdsl2LConfTempLineProfile that refers to the row.
When a row is created in this table, the SNMP agent should also
create corresponding rows in the tables
xdsl2LineConfProfModeSpecTable and
xdsl2LineConfProfModeSpecBandUsTable.
When a row is deleted in this table, the SNMP agent should also
delete corresponding rows in the tables
xdsl2LineConfProfModeSpecTable and
xdsl2LineConfProfModeSpecBandUsTable."

DESCRIPTION
"The table xdsl2LineConfProfModeSpecTable extends the DSL
line configuration profile by xDSL Mode-Specific parameters.
A row in this table that has an index of xdsl2LConfProfXdslMode
== defMode(1), is called a 'mandatory' row or 'default' row.
A row in this table that has an index such that
xdsl2LConfProfXdslMode is not equal to defMode(1), is called an
'optional' row or 'mode-specific' row.
When a row in the xdsl2LineConfProfTable table (the parent row)
is created, the SNMP agent will automatically create a
'mandatory' row in this table.
When the parent row is deleted, the SNMP agent will automatically
delete all associated rows in this table.
Any attempt to delete the 'mandatory' row using the
xdsl2LConfProfModeSpecRowStatus object will be rejected by the
SNMP agent.
The manager MAY create an 'optional' row in this table using the
xdsl2LConfProfModeSpecRowStatus object if the parent row
exists.
The manager MAY delete an 'optional' row in this table using the
xdsl2LConfProfModeSpecRowStatus object at any time.
If the actual transmission mode of a DSL line does not match one
of the 'optional' rows in this table, then the line will use the
PSD configuration from the 'mandatory' row.
Entries in this table MUST be maintained in a persistent
manner."

"The downstream PSD mask applicable at the U-C2 reference

This parameter is used only for G.992.5 and it may impose PSD

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

the RFI setup."
