Modem Figures

[basjke]

In the file attached you will see the statistics from my netgear modem.I am on TOT 2 Mb connection with no phone connected to the line.The modem has a direct line to the box TOT mounted outside my house of approximate 10 meter.No adsl splitter is attached.

The upstream and downstream noise margin are steady at those numbers.Reason I ask is that my modem disconnect from the exchange about 3 times an hour.Are the figures showed in the file reasonable or really to bad.

When I put the adsl splitter,given to me by TOT,between the outside line and the modem the downstream noise margin will heavily fluctuate between 3 and 9 db.The upstream noise margin stays steady.Is this better or worse then without the adsl splitter.Thanks for your replies.

You need [must use ?] the splitter to 'terminate' the line properly. The link to the splitter should be as short as possible, 10m is way too far. The noise margin is not extreme, neither is the frequent disconnection all that unusual, just damned tedious. You seem 'unlucky' with the line, the quality of which is often affected by poor connections long before it reaches you.

You can get a more reliable Internet service using Radio nowadays, such as the CAT CDMA offering, but it is more expensive to start; though a similar price monthly after that. [CAT = Communications Authority of Thailand, they have shops where you buy a package if you want to go down that route.]

Sticking with ADSL and TOT; I think everybody experiences 'service interruptions' quite regularly; especially if it rains. Sadly although ADSL is moderately 'hi-tech', the basic cabling technology is very frail & vulnerable once it leaves the Exchange.

Good Luck

PS - in my personal experience using a similar setup it 'got better' over time. No logical explanation I can offer, it just did.
