How to Train the ADSL/VDSL Modem Connected to the MA5652G to Be a VDSL Modem?

The following methods describe how to train the ADSL/VDSL modem to be a VDSL modem.

• Method 1: Select the VDSL-related protocol G.993.2 (Annex A/B/C) for transmission mode in the VDSL line profile.
• Method 2: Select the PTM mode for data path mode in the VDSL channel profile.

In the case of method 1, if the channel profile is set to both, the ADSL/VDSL modem may be trained to be an ADSL mode when unstable factors such as line environment noise exist. Therefore, if the ADSL/VDSL modem is connected to the MA5652G, method 2 is recommended.

If the modem connected to the MA5652G is not an ADSL/VDSL modem, in configuring the line profile and channel profile, set transmission mode to all and data path mode to both.
