New and Changed Information
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).

shows the CPE and
specifies which operating mode supports them.
A reduction in the power level occurs if there is excess margin on the line. For the downstream direction,
if there is excess margin, then IOS displays a reduction in margin for the modes listed above, and a
reduction in transmit power for T1.413 mode. For the upstream direction, if there is excess margin, then
IOS displays a reduction in the margin for g-992-1 mode only. IOS will not display a reduction in
transmit power for the upstream direction.

ATM OAM Cells Supported in Fast Path Mode
The NI-2 now supports atm oam cells through fast path mode. Also, you can now use the ping atm utility
command in fast path mode.

Enhanced ATM OAM Segment Cells Support
A new command, atm oam intercept segment, allows you to enable or disable receiving atm oam
segment cells on valid connections. By default, the atm oam cells received on unconfigured or down
connections are dropped. For more information, see the

MIB Object Changes
This release contains changes to the following Management Information Base (MIB) objects:
The power management feature is configurable via the CISCO-ADSL-DMT-LINE-MIB. The mib object
cAdslAtucDmtConfPMAddSnrMgn configures the downstream component and the mib object
cAdslAturDmtConfPMAddSnrMgn configures the upstream component on that particular dsl profile.
Both objects default to 0 and can be configured from 0 to 150 tenths of dBs in increments of 10. Setting
the objects to 0 explicitly via SNMP will disable the power management feature on the ports.
