Team,
I got a new broadband connection from BSNL, basically no other choice, in my area.
Model Name : T1-B-DSL699E9.4U6-5
Firmware Version : 10.4.3.12.12
Earlier I wanted to rent it, but was unwilling to spend 500 as initial deposit. So, in good faith I went ahead and paid BSNL 1800 to purchase it.
Now, the following is my Line statistics.
SNR (Downstream) 6.5 dB (Goes to a max of 12dB - evening hours)
SNR (Upstream) 13.5 dB
Line Attentuation(Downstream) 47.0 dB
Line Attentuation(Upstream) 31.5 dB
Connection Capability : PPoPE/ G.DMT (earlier ADSL2+)
Splitters removed. No phones used. Only modem is connected directly to line.
From day one, I am having disconnection issues. I have searched and searched and basically past 10 days have learnt more about ADSL networking than I would have cared to know. Made a thousand calls to BSNL, guys came in and checked the line. They (the lineman) says the line is fine, but even a child can say there is noise (again no phone when connected, no splitters etc.)
Yesterday, they made some changes in the exchange and I am getting slightly better SNR values, (around 10-12 dB) but still disconnecting. I have seen across some forums that different modem give different SNR values across the same line, and hence suspect may be the hardware.
Now my question is this:
If I go to BSNL and want to return their modem and replace it with my own (e.g. Linksys-WAG120N (Rs. 4500) or Linksys-WAG160N Wireless-N (Rs. 7500)), would they return my money (with probably some clerical processing fees).
I would have loved if some of my friends / neighbors could have a alternative equipment for me to test it with but that's not the case here. So before risking that kind of money I want to get advice particularly from users who are routinely living with low SNR and high attn values.
