Configuring a43, b43, and v43 Carrier Bands

Configuring a43, b43, and v43 Carrier Bands


  • The transmission mode of the VDSL interface has been set to ATM or PTM.

  • The VDSL interface has been deactivated.


Carrier bands a43, b43, and v43 on a VDSL interface allow the local device to connect to and negotiate with a digital subscriber line access multiplexer (DSLAM). By default, carrier bands are enabled on the VDSL interface and the local device selects a carrier band through auto-negotiation with the DSLAM. If the DSLAM does not support a carrier band, disable the carrier band.


  1. Run system-view

    The system view is displayed.

  2. Run interface ethernet interface-number

    The view of the VDSL interface working in PTM mode is displayed.

  3. Run vdsl band { a43 | b43 | v43 } { off | on }

    A specified carrier band on the VDSL interface is enabled or disabled.

    By default, carrier bands are enabled on a VDSL interface.
