Setting the PSD Mode for a G.SHDSL Interface
Context
The router must be configured with the same power spectral density (PSD) mode as the peer device. The router supports the following PSD modes:
Symmetric PSD: The G.SHDSL interface is spectral-compatible with other services, uses less power, and is suitable for short-distance transmission.
Asymmetric PSD: The G.SHDSL interface uses a high output power for better transmission performance and is suitable for long-distance transmission.
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:
- Run shdsl psd { asymmetry | symmetry }
The PSD mode is set for the G.SHDSL interface.
By default, the PSD mode of a G.SHDSL interface is symmetric PSD.
