Setting Uplink Parameters for a VDSL Interface (in ATM Mode)

Procedure

1. Run system-view

   The system view is displayed.

2. Run interface atm interface-number

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

3. Run adsl standard { adsl2 [ annexa | annexm | annexb | annexj | annexl ] | adsl2+ [ annexa | annexm | annexb | annexj ] | auto [over-pots | over-isdn ] | gdmt [ annexa | annexb ] | t1413 }

   The transmission standard is configured for the VDSL interface in ATM mode.

   By default, the transmission standard of a VDSL interface in ATM mode is auto.

   AR617VW, AR617VW-LTE4, AR617VW-LTE4EA, and AR657W(50010486) only support AnnexA and AnnexM.

4. Run adsl bitswap { off | on }

   Bit exchange is configured on the VDSL interface.

   By default, bit exchange is enabled on a VDSL interface.

5. Run adsl sra { off | on }

   Seamless rate adaptation is configured on the VDSL interface.

   By default, seamless rate adaptation is disabled on a VDSL interface.

6. Run adsl trellis { off | on }

   Trellis coding is configured on the VDSL interface.

   By default, trellis coding is enabled on a VDSL interface.

7. (Optional) Enhance line performance of the VDSL interface.

   Only the AR617VW, AR617VW-LTE4EA, AR617VW-LTE4, 1V35B-AM, and AR657W devices support this configuration.

   Only V300R019C11 and later versions support the function.

   • Run undo vdsl upstream-retrans enable

     The upstream retransmission function is disabled on the VDSL interface.

     By default, the upstream retransmission function is enabled on a VDSL interface.

   • Run undo vdsl downstream-retrans enable

     The downstream retransmission function is disabled on the VDSL interface.

     By default, the upstream retransmission function is enabled on a VDSL interface.

   • Run vdsl anti-noise enable

     Enhanced noise resistance is enabled on the VDSL interface.

     By default, enhanced noise resistance is disabled on a VDSL interface.
