Sup Gents,

I dont know if anyone can really assist me on this one. We have ordered 4mb DSL from telkom and they have upgraded our line but the line drops often aswell as it never syncs at the same speed every few minutes it will go to anything between 700kbps and 2500kbps. Telkom have even replaced the lines in the house and still no luck. :confused:

Now some technical guy that works at the exchange in my area told me my line cannot go any faster because of the attenuation. So I have come to terms with the fact that I will never get 4mb(Still figuring out a way I could possibly lower my attenuation) but the fact remains that the line is not consistent. :eek:

This is a desperate attempt to get some answers! Thanks. ;)

Here is some info: Netgear DGN2000

ADSL Link Downstream Upstream
Connection Speed 2208 kbps 512 kbps
Line Attenuation 54.0 db 30.5 db
Noise Margin 1.9 db 14.0 db

and another about 5 min later.

ADSL Link Downstream Upstream
Connection Speed 2272 kbps 512 kbps
Line Attenuation 54.0 db 30.5 db
Noise Margin 6.0 db 13.0 db
 
Dude that line doesn't look good at all. The only difference between the two is the slight increase in noise margin?
 
Here is a another one

ADSL Link Downstream Upstream
Connection Speed 2016 kbps 512 kbps
Line Attenuation 54.0 db 30.5 db
Noise Margin 6.1 db 13.0 db

I had 512kbps for a long time and it never changed. Is it suppose to be so irregular? And any ideas what could be at fault?
 
Upstream 512000
Downstream 4096000
SNR Margin(Upstream) 27 dB
SNR Margin(Downstream) 22.0 dB
Line Attenuation(Upstream) 4.5 dB
Line Attenuation(Downstream) 8.0 dB

this is what line should look like thats my readings
 
Seriously bad line, here is mine on 4Mb
ADSL Link Downstream Upstream
Connection Speed 4096 kbps 512 kbps
Line Attenuation 12 db 2.5 db
Noise Margin 15 db 14 db

Apply for another line with ADSL - expensive route & drop the original one if the new own is better.
It could be the drop wire from your house to the pole behind your property to the exchange

Follow the route if above ground and Speak to your neighbours who have ADSL and check their attenuation stats
 
Would that actually make a difference? Because if it does then maybe ill do it. Thing is though, none of us in the house use the landline at all. So its basically have just a line for dsl.
 
Found this on another posting

Try this:

Apply for a second, new Telkom Line, but choose Closer option 2 - it comes with free installation, and the monthly cost is about R150, about R20 more than normal line rental.

Once the line is installed, then see if the voice quality is better than your other line. If it is, then apply for ADSL, but tell them you want to apply for ADSL access only, and you will use your own ISP. Once ADSL is installed, get a 1GB account from Afrihost at R29 to use for testing. Test to see how good your connection is. If it is good, then cancel your old line completely, and just use the new one, for both Voice and ADSL. You will obviously lose your old number - hopefully you can live with that.

If it's not good, then something is wrong somewhere along the line between the exchange and your house, and all you've lost is about R180 (R150 + R29 - Afrihost 1GB, month to month account), and maybe a few weeks to a month of time, depending on how fast Telkom install your new line.

It might be easier to do this than getting Telkom to come and test your line 100's of times with no results.

Thats awesome. I think ill try that. Ive tried to follow the line but it goes straight to the backyard and the pole is over the wall. Behind that wall is a shopping centre, so I doubt I will be able to walk around in the loading bay area looking for the line :P
 
Are their any large electrical devices (airconditioning) that can cause induction into the line.
If you plug a telephone onto the line is the line clean no static, no humm

Tell the Telkom person to make a note of it that of the new line is still noisy with high Atten
you are not going to pay for bad quality lines

From the house to the pole, there is nothing electrical near it. From the Pole and to where ever it leads to, from what I can see there is Aircons but they roughly 20m or more away from the line. I had a listen on the phone for any noise, seems like there is a electrical hum noise in the background, ever so slight though but its definately there.

This is todays sync:
ADSL Link Downstream Upstream
Connection Speed 1632 kbps 512 kbps
Line Attenuation 54.0 db 31.0 db
Noise Margin 5.9 db 10.0 db
 
Maybe switch the power in your home off to see if it externally induced or internal from one of your devices.

Process of elimination by substitution
 
Well I have gotten an answer from telkom. Seems like after the telkom technician replaced the line at home, they have realised there is a problem somewhere between the pole and the exchange. :(
 
Hopefully they can restore the line back to acceptable specs for you
 
My line is just as bad and it's between the exchange and pole, telkom don't plan on fixing it either. I have 384 connection and it's unstable so anything higher would be a waste for me.
 
Lol. We moved to this house so we just asked for a transfer and while they did that we upgraded from 512 to 4mb. Thats how... haha. Does anyone know if telkom would put a point by the pole and then have your router sitting there and pull a network cable through to the house? Im sure that would reduce line attenuation?

well you could do that on your own cos the cable going to your is the same thing u plug-in inside your house but u might find ur modem not liking exposing to elements like rain and burning hot sun :p
 
Haha, well ide definately have to house the router somehow. It just got me thinking, because I changed the long 20m telephone cable to my router to a 3m one and I got 1db off my attenuation. :P

yo man i have the same problem, but i got it sorted out but at a cost, what u must do is have them sync yr line at 3mb then test it, if it drops take it lower to 2 then test it, my 4mb line cant take 3 mb even, its stable at 2mb
 
They have told me already that it cant go higher than 2400kbps but the problem is the fact that my adsl connection drops randomly. Sometimes when it syncs it only goes to speeds of around 700kbps. So yeah.... :(
