downstream margin ok (good) but for upstream not ok.
slow download from file hosting (even premium user) are not effected by margin status, its because our ISP.

I'm wondering, I have a line attenuation of around 43dB and an SNR margin of around 20dB.

Is this normal?

I was having frequent disconnection earlier today but after the TM technician came (dialed 100 to report), uptime seems to be extending, which is good

SNR margin was at 17dB but can get as low as 6dB.
Seems to be ok for now. Nothing much he did except testing the phone line and made some calls. I guess the phonecall did make a difference.

U have changed to G.dmt right ?

Did your SNR margin increase.
Please connect your telephone cable to modem only > restart modem > and upload the SNR margin again.

Attention to all Users,
Your SNR margin must at least 12dB. higher better.

What caused Disconnection, DSL light Blinking, / How to increase my SNR margin
1. Bad Internal Cable wiring, ( example, your house > 10 years, please change your house telephone wiring )
2. Bad External Phone Wiring. ( Rewiring )
3. Your Phone line got noise - call 100 to fix it.
4. Your Phone has alarm system - apply for another line.
5. Request other brand of Modem to test ( borrow from frd )
6. Use shortest telephone line. avoid using old phone line, avoid using long phone line
7. Remove Spliter, Remove all phone cable, Remove Surge protector.

FAQ:
Q: I got SNR Margin below 12dB, what can i do.
A: First, Is your connection stable? (Yes, nth i can do ) (No, Please read above)

Q: I got SNR Margin above 12dB, but always disconnect, What can i do.
A: Make sure u connect your phone line directly from Phone socket to Modem.

Q: I apply for 512kbps package, but i check in Modem, it stated 2048kbps or 1536kbps.
A:
1. Is your SNR margin below 12dB, and frequently disconnect ?
Yes, Request TM technician to lower the speed capped at the DSLAM. once they did, your modem will state. as your package speed.

Rate my post if this is usefully.
Thanks.

i think this manual would help u to tweak the modem
Preliminary Viking™ Chip Set Family CLI Reference Manual
if not mistaken, there is a command to cap ur modem manually, but i don't sure it works or not
this guide maybe the key to reduce the Rx line rate from your side
