adsl pmm enable <portlist>

<L2|L3>

Enables Power ManageMent (PMM) to reduce the amount of

power used overall and reduce the instances of the connection

going down. PMM increases or decreases the transmission

power based on line conditions. PMM also reduces the number

of service interruptions.

L2: Low Power. Sets the power management feature to scale

back line usage to the minimum level sufficient to maintain an

active connection when there is low level of traffic.

L3: Idle. Sets the power management feature to reduce the

power consumption when there is no traffic. Ports may be

disabled or go into monitor mode in this state.The power level

comes back up when there is traffic.

H/H

adsl pmm set <portlist> <L0|L2> Sets the power management mode.

L0: Turns off power management on a port.

L2: Low Power. Sets the power management feature to scale

back line usage to the minimum level sufficient to maintain an

active connection when there is low level of traffic.

H/H

adsl pmm param

<portlist>[<l0time><l2time><l2at

pr><l2atprt>][<max-l2rate><min-

l2rate><l0tol2-rate>]

Displays or sets PMM parameters for the specified ADSL

port(s).

l0time: Set the minimum time in seconds (10~65535) that the

ADSL line must stay in L0 power mode before changing to the

L2 power mode.

l2time: Set minimum time in seconds (10~65535) that the

ADSL line must stay in the L2 power mode before reducing the

power again in the L2 power mode.

l2atpr: Set the maximum Aggregate Transmit Power

Reduction (ATPR) in decibels (dB) that is permitted in a L2

power reduction. The system can gradually decrease the

ADSL line transmission power while it is in the L2 power mode.

This is the largest individual power reduction allowed in the L2

power mode. The range is 0~15(dB).

max-l2rate: Set the maximum transfer rate (in Kilobits per

second) that is permitted while the port is in the L2 power

mode. The supported range is 32~4096 Kbps in 4 Kbps

increments. If you enter a number that is not a multiple of 4, the

system uses the next lower multiple of 4. If you enter 39 for

example, the system will use 36.

min-l2rate: Set the minimum transfer rate (in Kilobits per

second) that is permitted while the port is in the L2 power

mode. The supported range is 32~4096 Kbps in 4 Kbps

increments. If you enter a number that is not a multiple of 4, the

system uses the next lower multiple of 4. If you enter 39 for

example, the system will use 36.

l0tol2-rate: Set the down stream transfer rate (in Kilobits

per second) that serves as the threshold for whether the port is

to use the L0 or the L2 power mode. The system changes from

L0 mode to L2 mode when the downstream transfer rate stays

below this threshold for L0 Time. The system changes back

from L2 mode to L0 mode when the downstream transfer rate

goes above this threshold. This rate must be less than or equal

to one half of the Min L2 Rate and at least 16 Kbps.

H/H

adsl pmm show <portlist> Displays the PMM settings for the specified port(s). M/L

adsl pmm disable <portlist> Turns off PMM on the specified port(s). H/H
