ADSL and my phone line -- EDIT

[LeetViet]

From my modem:

DSL Connection Details
DSL Line (Wire Pair): Line 1 (inner pair)
Protocol: G.DMT Annex A
Downstream Rate: 3488 kbps
Upstream Rate: 800 kbps
Channel: Fast
Current Noise Margin: 9.0 dB (Downstream), 9.0 dB (Upstream)
Current Attenuation: 49.6 dB (Downstream), 31.0 dB (Upstream)
Current Output Power: 17.5 dBm (Downstream), 11.9 dBm (Upstream)
DSLAM Vendor Information: Country: {0x0F} Vendor: {ALCB} Specific: {0x00}
PVC Info: 0/35

I've swapped all the filters and cables in the house for new ones.

Is there anything I can do to increase my line stats (increase noise margin, decrease attenuation)? Has anyone else been in a similar situation where they were held back by their phone line stats?

Edit:
Response from my ISP:

you're sitting at approx 4.5km from the CO and you're pretty much maxed out as far as stability...unfortunately short of moving/Bell installing a closer remote(you're already over 1meg so doubtful) you're at the best your line will handle...

That's that.

Put the modem directly on the NID, if you get the same stats talk to your DSL provider.

Otherwise, you can lay a line directly from the NID to the DSL Modem, or rewire the house.

I'm not sure what you mean by NID. My modem/router is a 2Wire 2700HG.

 

[JackMDS]

NID = Network Interface Device, it is the box that the Telco. put somewhere at the house and connects to one side its outside wire, and the house lines to the other side.

The reason to try it is to determine whether your signal is better when connected directly to the Telco. line, if it is better than you home's lines (wire in or out of the walls) are "bad".

If he is at the distance the telco says, then wiring a whole house dsl filter at the point of entrance
and running a line from that to the DSL Modem / Router is the best answer.
DSL does not like a lot (anything over 3) individual set filters on the line as it does degrade the
signal, especially if you are near the distance limit. When the whole house filter is installed,
all the individual set filters get removed ... A bit of trouble to do, but well worth it.

You could either buy the filter yourself (about $30) or insist the telco come out and install one
for you, but they may charge for it & you would still need to run a cable from it to the modem
yourself or pay the telco tech to do it. They normally will not volunteer the filter as DSL is promoted
as "Install It Yourself" (aka: telco is cheap and does not want to pay a tech to go to your home)

I am going to guess that your connection is unstable currently. If this is not the case, why try to fix something that is not broken?

Now, as far as what to do about improving the connection statistics of your connection, trying the NID as Jack suggested and possibly running a dedicated line to your modem are your only choices that you can do yourself. The remaining will have to be handled by the telco.
