ADSL Mode
Connect Mode: This mode will automatically detect your ADSL line mode, ADSL2+, ADSL2, G.dmt, G.lite,
T1.413, AnnexM2 or AnnexM2+. But in some areas, multimode cannot detect the ADSL line mode very well. If it
is the case, please adjust the ADSL line code to G.dmt first. If it still fails, please check with your ISP for line
connection information.
Modulation: It will automatically detect capability of your ADSL line mode. Please keep the factory settings unless
ADSL is detected as the symptom of a synchronization problem.
Profile Type: The profile type should be left in the default settings unless the ADSL mode is determined as the
symptom of low link rate or instability problems. If such a problem is encountered, the profile setting may need to be
changed to conform to the different DSLAM in the area.
Activate Line: Select false and then select true to activate any new Connect Mode settings.
Coding Gain: This reduces the router’s transmit power and will effect to router’s downstream performance.
General, the higher the gain, the higher the downstream rate, but sometimes a gain that is too high will cause an
unstable ADSL connection. The configurable ADSL coding gain is from 0 dB to 7dB, or automatic.
