Setting the Transmit Power of a G.SHDSL Interface
Context
Normally, an interface adjusts its transmit power based on the line noise to achieve a proper SNR. When the noise is known or the rate automatically adjusted by the interface is inaccurate, you can manually adjust the transmit power.
Procedure
- Run system-view
The system view is displayed.
- Run either of the following commands to enter the G.SHDSL interface view.
- If the transmission mode is set to ATM, run:
interface atm interface-number
- If the transmission mode is set to PTM, run:
interface ethernet interface-number
- If the transmission mode is set to ATM, run:
- Set the transmit power of a G.SHDSL interface.
- After the shdsl pbo auto command is executed, the interface adjusts the transmit power according to the line noise.
- When the noise is known or the rate automatically adjusted by the interface is inaccurate, you can run the shdsl pbo value command to manually adjust the transmit power.
By default, the auto mode is used.
