29.4.13 port adsl pmm enable Command
Syntax:
port adsl pmm enable < slot-port > [L2|L3]
where
This command turns on the Power Management Mode (PMM) feature on the specified ADSL2/2+
port(s). This reduces the amount of power used overall and reduces the instances of the connection
going down. PMM increases or decreases the transmission power based on line conditions.
The following example sets ADSL2+ port 5 on the line card in slot 7 to use power management.
29.4.14 port adsl power Command
Syntax:
port adsl power < slot-port > fix|power|rate < max_us_txpwr > < max_ds_txpwr > < max_rxpwr >
where
This command specifies the maximum allowed transmit power and maximum aggregate received
power.
L2
=
Power management mode L2. This is a power saving mode that scales back the power
usage to where there is just enough to support the transmission rate that the subscriber is
using.
L3
= Power management mode L2 and L3. Power management mode L3 is a power saving
mode that puts the ADSL connection to sleep when there is no traffic. The connection
comes back up within three seconds when there is traffic.
ras> port adsl pmm enable 7-5
fix|power|rate
=
The PSD (Power Spectral Density) and power adaptivity mode.
fix
: Fixed mode sets the maximum downstream transmit power to the
number you specify (
<max_ds_txpwr>).
power:
Power mode gives the saving of transmission power priority over
the transmission rate. The line card attempts to reduce its transmit power as
much as possible while still maintaining the configured minimum rate. This
only applies to the downstream connection and the ADSL operational mode
must be G.dmt, ANSI T1.413 or G.lite.
rate
: Rate mode gives the transmission rate priority over the saving of
transmission power. The line card attempts to achieve the maximum
configured transmission rate before reducing the transmit power.
< max_us_txpwr >
=
Maximum upstream transmit power, -130~200 in 0.1 dBm.
< max_ds_txpwr >
=
Maximum downstream transmit power, -50~200 in 0.1 dBm.
< max_rxpwr >
=
Maximum aggregate receive power at atu-c, -255~255 in 0.1 dBm.This only
applies to the ADSL2/2+ ADSL operational modes.
