get your tel. line/splitter checked properly by bsnl.SNR should be around 25-30 and 15-20 for download and and upload respectively and attenuation around 10-15 or less for better performance.

Hi I am also having the problem with frequent disconnection of bsnl dataone from the beginning.3 months before I took BSNL BB. They have provided the ut300ru modem and the attn,SNR statistics are 13.3 / 6, 46 / 21.5 for downstream and upstream respectively. My Dsl link is stable after 30 mins only but it gets disconneced after 2 or 3 hours. After resuming the username changes to multiplay.Why this is happening?I have the proper BB setup in my premises.Pl help me to get this problem solved.

as u said downstream snr should be higher...but reverse is in my case...why upstream snr is higher? does it mean that my upload speed is higher??

Downstream Upstream
SNR Margin (dB): 7.3 13.0
Attenuation (dB): 26.0 15.5

i get disconnection whenever call comes...my adsl splitter has no probs..

SNR (Signal to Noise Ratio) is not directly related to speed of the connection. It's like a comparison of signal strength, and noise corrupting the signal. The reason for low SNR generally means problem with phone line. Also it doesn't matter if SNR Upstream is higher than Downstream. Attenuation means loss of quality of signal. The loss of signal quality should be less of course.

The best thing to do is book a complaint to BSNL customer care.

What Archer said ^^^^^. Plus you probably need to convince them to change all telephone wires that run into your house.

.......Change mod to GDMT and see any improvement in SNR.
........You may have to uncheck adsl2+ and adsl2
......... keeping GDMT T413 Glite and bitswap enabled.

It must be a problem with phone line. Like I said " book a complaint to BSNL customer care." BSNL have the responsibility to give you the promised connection speed without any problem.

ensure that all telephones are connected after splitter.. try this, disconnect all telephones temporarily and restart modem and see if your SNR improves..

Show how your phones are connected .
Any extension phones in other rooms directly from BSNL telephone PORT ?

1.Try dialer mode.
2.Connect DIRECT from Phone junction RJ11 to modem.( No splitter No phones )
3. Post IP config/all data
