well friends,
using BSNL dataone for more thn one year,lately it has got some problems..I loose sync at times ( the link goes off ) and it sucks !!! specially 2 to 8...
I checked my modem data and changed my ADSL modulation to G.dmt and the problem was solved somewhat..but it is still there.I have joined the telephone cable directly to my modem ( no phone) and got the cable changed after running after BSNL wallas ..
Well, Here are my modem stats:

UPSTREAM DOWNSTREAM
ADSL Link Speed 736 Kbps 9568 Kbps

Previous Tx-Rate 672 Kbps 10016 Kbps

SNR 15 dB 7.5 dB


Attenuation 11.5 dB 25.0 dB



I fear that some wiring fault is at DSLAM at exchange and I want to confront BSNL JTO on this ground..

Can somebody clarify why the upstream SNR is more then Downstream ?

regards ..
