VDSL uses PTM which the modem is set up to use by default.
ADSL uses ATM which you have to configure the modem to use.
I don't believe that's necessary if the HG612 is used with default bridged mode settings with a router attached.
These are the default settings (all flavours ADSL enabled apart from AnnexM):-
xdslcmd profile --show
Modulations:
G.Dmt Enabled
G.lite Enabled
T1.413 Enabled
ADSL2 Enabled
AnnexL Enabled
ADSL2+ Enabled
AnnexM Disabled
VDSL2 Enabled
Phone line pair:
Inner pair
Capability:
bitswap On

phyReXmt(Us/Ds) Off/On

monitorTone: On
dynamicD: On
dynamicF: Off
SOS: On
Training Margin(Q4 in dB): -1(DEFAULT)
I think some of the Capability settings are automatically changed slightly when the modem is used for ADSL connections.
The modem's default IP Address is 192.168.1.1 & admin is used for both Username & password.
Windows users should be able to use the 'arp -a' command in a command window to see what is connected.
e.g:-
C:\Users\Paul>arp -a
Interface: 192.168.1.100 --- 0xa
