New Software Features in Release 12.2(10)DA
The following new software features were introduced in Cisco IOS Release 12.2(10)DA.
DMT Power-Management-Additional-Margin
The 8xDMT line card can run in power-management mode in the G.dmt or the T1.413 mode. The
resulting power cutback produces a reduction in power dissipation and crosstalk. Only 8xDMT line cards
support power management. All CPE may not support the DSL functionality for power management to
function correctly. Check with a Cisco customer representative to verify CPE compatibility with the
8xDMT power management.

8xDMT power management.
You control the Power Management feature by issuing a dmt power-management-additional-margin
command inside a profile and assigning that profile to a line card interface. This IOS command allows
you to set the additional margin for each channel from 0 dB (off) to 15 dB. This sets the additional
margin that will be added to the target margin. If the sum of the target margin and additional margin
exceeds 15dB, it is capped at 15dB. If the actual margin of the line is higher than the sum of the
configured target and additional margin, and all the above conditions are met, then power management
attempts to reduce the actual margin, and as a consequence the power level as well.

Not all CPE support power management. If you connect an unsupported CPE to a port on which power
management is turned on, you will not see a reduction in the actual margin or power level. The operating
modes supported by power management are T1.413and g-992-1 (G.DMT).
