is set up between the two parties. When negotiating connection parameters during the line activation,
the CO equipment provide and decide values for most parameters, while the CPE accept them.
Contrary to activation, deactivation tears down the communication connection between the two parties.
The router tests the performance of the line regularly. Once it finds out that the line performance is
deteriorating, it automatically deactivates, retrains, and reactivates the line.
IMPORTANT:
Make sure regular twisted pairs are used and the cables are well connected when connecting ADSL
interfaces, because the ADSL transmission rate is susceptible to the transmission distance and line quality.
This section covers only the physical configurations of the ADSL interface. For more information about
how to configure ATM (including PVCs), see Layer 2—WAN Configuration Guide.
Configuration procedure
To configure an ADSL interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter ATM interface view.
interface atm interface-number N/A
3. Activate the ADSL interface.
activate
Optional.
The interface is active by default.
4. Configure the ADSL interface
standard.
adsl standard { auto | g9923 |
g9925 | gdmt | glite | t1413 }
Optional.
The default setting is auto sensing.
5. Set the transmit power
attenuation value.
adsl tx-attenuation attenuation
Optional.
The default value is 1.
6. Set the intended bandwidth
for the ADSL interface.
bandwidth bandwidth-value Optional.
7. Restore the default settings for
the ADSL interface.
default Optional.
NOTE:
To have the adsl standard command configuration take effect on an interface, you need to re-activate the
interface either by executing the shutdown and undo shutdown commands or the activate and undo
activate commands.
Upgrading ADSL2+ card software
The upgradeable software includes BootROM and card software. You first need to load the new software
by FTP or some other means to the flash memory or the CF card on your device. Before performing an
upgrade, you need to shut down the interface with the shutdown command if the interface is up. After
completing the upgrade, you need to bring the interface up with the undo shutdown command.
