Release 12.2(10)DA2 is based on Cisco IOS Release 12.2(10)DA1 and 12.2(10)DA and includes 

all of the new features introduced in that release. In addition, this release fixes the bugs described in 
the

“Resolved Caveats—Release 12.2(10)DA1” section on page 16

. 

No new hardware features were introduced in Cisco IOS Release 12.2(10)DA2.

The following new software features were introduced in Cisco IOS Release 12.2(10)DA. No new 
features were introduced in Release 12.2(10)DA2.

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.

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.
