ADSL
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 connect information.
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.
Tx Attenuation: This is the ADSL transmission power that the modem is using. The lower the power
the better performance in router’s upstream. Configurable value is between 0~12.
DSP Firmware Version: Current ADSL line code firmware version.
Connected: Display current ADSL line sync status.
Operational Mode: Display current ADSL mode standard (Operational Mode) that your Router is using
when ADSL line has sync.
Annex Type: ADSL Annex A, which works over a standard telephone line. Annex B, which works over an
ISDN line. In South Africa, we always use Annex A
Upstream: Display current upstream rate of your ADSL line.
Downstream: Display current downstream rate of your ADSL line.
