Connect Mode: This mode will automatically detect your ADSL line code, ADSL2+, ADSL2, G.dmt,
G.lite, T1.413, AnnexM2 and AnnexM2+. But in some area, multimode cannot detect the ADSL line code
well. If it is the case, please adjust the ADSL line code to G.dmt or T1.413 first. If it still fails, please try the
other values such as ALCTL, ADI, etc. If you still having trouble with the line, please check with your ISP
for line connect information.
Note: If you have subscribed ADSL1 T1.413 mode line, you may go to the Advanced Options for more connection
module combinations.
Activate Line: Aborting (false) your ADSL line and making it active (true) again for taking effect with
setting of Connect Mode.
