QUOTE(vyzc @ Mar 17 2007, 10:34 PM) Guys, attached below is a screenshot of the status of my ADSL line:  I am currently subscribed to the 1Mbit package, but I can only sync at about 600-700 Kbps instead of 1024 Kbps. I've tried restarting my modem many times, but yet the sync rate stays within 600-700 Kbps. During one of the restarts, I managed to sync at 1024 Kbps but it only lasted for a minute or so, before the 'DSL' light on my modem blinked and I lost my synchronization. Can this be due to my phone line quality? As you can see in the screenshot above, my SNR margin is quite poor. I'm getting high line attenuation too. BTW, my line is connected to an RDSLAM which is located a few hundred metres away from my house. Any advice would be much appreciated. Guys, what do you think of my line as shown above? I'm connected to an RDSLAM that's only a few hundred metres away from my house.

Downstream SNR = 15 dB.
Higher is better, minimum = 6 dB.
Downstream Power = < 15 dBm.
Lower is better.
Upstream SNR = 10 dB.
Higher is better.
Upstream Power = < 15 dBm.
Lower is better.
Downstream Attenuation = < 30 dB
Lower is better, maximum = 60 dB.
Upstream Attenuation = < 30 dB
Lower is better, maximum = 60 dB.
3.2 ADSL2+
Downstream SNR = 06 dB.
Higher is not better, within range is better = 05 - 07 dB.
Downstream Power = < xx dBm.
Lower is better.
Upstream SNR = 06 dB.
Higher is not better, within range is better = 05 - 07 dB.
Upstream Power = < xx dBm.
Lower is better.
Downstream Attenuation = < 22 dB
Lower is better, maximum = 22 dB (for 10mbps), 12 dB (for ~25mbps).
Upstream Attenuation = < 22 dB
Lower is better, maximum = 22 dB (for 10mbps), 12 dB (for ~25mbps).
Attenuation to Loop Length Conversion
10 dB ~ 0500 m 15 dB ~ 1000 m 25 dB ~ 2000 m 35 dB ~ 2500 m

Hmm, didn't get any feedback from you guys regarding my previous problem but I'll share this with you all anyway. Got my line re-routed from the main DSLAM to an RDSLAM near my house. Problem solved! However, I'm getting IP addresses in the range of 60.x. I think I might be going through some fibre optic lines.  Previously, the SNR ratio was about 10dB and the line attenuation, 55-57dB.

guess mine isn't too good eh... damn... is it the only way to fix is call up streamyx? and what should i say in the phone?

Now...

Peak Cell Rate 603 cells per sec CRC Rx Fast 0 CRC Tx Fast 0 CRC Rx Interleaved 17081 CRC Tx Interleaved 24 Path Mode Interleaved
The weirdest thing is, although my SNR is lower but I can connect the net for 11 hours without disconnection.
Before this, every 1 hours I will have a disconnection.
Weird: 1. trained modulation changed... 2. US line attenuation become from 31 to 6 3. Path Mode changed... What does that mean?

QUOTE(TheXxBestxX @ Mar 14 2007, 04:22 PM) Since my DS margin is very low(6-7db), I'm guessing my house is located far away from the DSLAM.
After I have report this case to TMNet, then the technician have do the checking to DSLAM.
The technician have told me that the distance from my house to DSLAM exchange is only 3.5KM.
After that, nothing have been changed(still disconnection happen)...REALLY CANNOT EXPECT SOMETHING MORE FROM TMNut!!! This post has been edited by lexu2005: Mar 23 2007, 04:53 PM
