Procedure
Step 1 Set the working mode for VDSL interfaces on the Router to ATM.
<Huawei> system-view
[Huawei] sysname Router
[Router] set workmode slot 1 vdsl atm
Changing the working mode will reset the board in slot 1. Continue? [y/n]:y
INFO: Resetting board[1] succeeded.
By default, VDSL interfaces work in PTM mode.
Step 2 Deactivate ATM1/0/0.
[Router] interface atm 1/0/0
[Router-Atm1/0/0] shutdown
Step 3 Configure the transmission standard auto for the VDSL interface.
[Router-Atm1/0/0] adsl standard auto
Step 4 Enable bit exchange on the VDSL interface.
[Router-Atm1/0/0] adsl bitswap on
Step 5 Disable seamless rate adaptation on the VDSL interface.
[Router-Atm1/0/0] adsl sra off
Step 6 Enable trellis coding on the VDSL interface.
[Router-Atm1/0/0] adsl trellis on
Step 7 Activate ATM1/0/0.
[Router-Atm1/0/0] undo shutdown
Step 8 Verify the configuration.
# Check the training status, transmission standard, line status, performance statistics, bit
exchange status, seamless rate adaptation status, trellis coding status, and board version of the
VDSL interface.
