Thumbs up G.dmt vs ADSL2+

:thumbup1:For stable ADSL link ,G.Dmt is the standard if your cable quality is poor
If you are within 5 Kms range from Exchange you can try ADSL2+ for better upload

For you GDMT connection is recommended.

You can select AUTO mode.
or
keep only adsl2+ adsl2 and bitswap enabled.

I feel, changing to ADSL2+ will not show
improvment for you.
Very good SNR( 28.4 db) and AttN ( 13.0 db)figures ( D/L mode )
even though you are 5Kms
away from the Exchange.


Anyway try and give feedback.

I had observed the mod mode is not
always same. If all are selected,
it can change, depending on ISP.
( now on Airtel) specially with BSNL.
Sometimes you don't get connection
if, say Gdmt is not selected!
will update later with Bsnl data one.
wait Changing.

Code:
12:08 PM 4/7/2009 beetel 110BX1
Mode:  	G.DMT  ( adsl2+ unchecked Dataone 59.96.xxx.xx)
 
  	Downstream 	Upstream
SNR Margin (dB): 	32.9  	24.0 
Attenuation (dB): 	16.0  	3.0 
Output Power (dBm): 	12.3  	15.1 
Attainable Rate (Kbps): 	8864  	992
