ADSL Parameters help to interpret your ADSL line statistics.
SNR Margin: This is known as Signal to Noise Ration Margin. It is the ratio between DSL strength and
signal noise. This margin is measured in decibels (dB). Higher the dB figures better the DSL strength is
relative to the noise, and better chance to get faster speed. THE HIGHER THE BETTER
Line Attenuation: This measures the signal loss in decibel (dB) between the DSLAM and the router. The
lower the attenuation dB figures, the better the DSL strength/speed. THE LOWER THE BETTER.
CRC Errors: It is known as Cyclic Redundancy Check Error. It is the use of checksums to detect
transmission errors.
Latency: This includes two channels, Fast and Interleaved. It displays the channel adopted by your ISP.
Capability: There are more combinational ADSL modulation modes to be selected.
GDMT: ADSL connection will be limited to ADSL1 (G.DMT / G.Lite) only.
BIS+: ADSL connection will be limited to ADSL2+ only. (If you are ADSL1 subscriber DO NOT
select this option).
BIS+/T1413: ADSL connection will be limited to ADSL2+ and ADSL1 T1.413 only.
BIS+/BIS: ADSL connection will be limited to ADSL2+ and ADSL2 only.
BIS+/BIS/GDMT/T1413: ADSL connection will be limited to ADSL2+, ADSL2 and ADSL1
G.DMT & G.Lite & T1.413.
BIS+/BIS/T1413: ADSL connection will be limited to ADSL2+, ADSL2 and T1.413.
BIS+/BIS/GDMT: ADSL connection will be limited to ADSL2+, ADSL2 and ADS1 (G.DMT/G.Lite)
only.
DISABLE: This disable function will disconnect your ADSL synch. Use it with caution.
S=1/2 Mode: This is a ADSL1 protocol that can increase the downstream speed up to 12Mpb. Please
check further with your ISP if this option can be enabled or not.
