My 1024 kbps line stats (New MSANS)

Geezus!!!!, those are some good stats, I am still on 39db downstream Attenuation, dammit!! :twisted:

Just wish they can start with the damn upgrades to 1Mbps. Cant wait.

Will it only start in August or this month cause all the articles is making me confusing??

Your downstream SNR margin seems quite low considering your attenuation.

Here are my stats on my 10Mb line:
ADSL Link Downstream Upstream
Connection Speed 10015 kbps 1023 kbps
Line Attenuation 16.5 db 10.0 db
Noise Margin 16.7 db 6.8 db

My noise margin downstream was about 29db when I was still on 4Mb

Your SNR is low yourself. I'm on 384 about 2-3km from the exchange, and I'm sitting with 26.6/18.0db down/up SNR, and my attenuation is pretty high: 43.5/25.0 down/up. I thought low SNR = can't sync?

True, but your SNR drops as your speed increases, my SNR is high 32 but I am on 384 so I cannot compare it to someone who has a 4meg line.

This is also why they try drop your speed when you have connectivity issues.
 
I know where my DSLAM is, and it was replaced with a MSAN a while ago but left "unplugged" - there are about 4 Telkom techs around it at the moment (been there for hours) so I can only assume my switch is soon. It couldn't come any quicker, as I have Attenuation of around 63bb and SNR around 14db - however, my line is immaculate and has never given issues.

The higher the sync speed the lower your SNR margin will get, as I said I had a noise margin around 29db on 4mb before the upgraded us to 10Mb.

Anything higher than 12db will keep a solid sync and a good router will be able to sometimes sync as low as 6db.
 
I am also on a MSAN. Like the OP I am also renting a 1 meg line, but as you can see on the last line ;)


SNR Margin (0.1 dB): Downstream 152 Upstream 70
Attenuation (0.1 dB): Downstream 90 Upstream 28
Attainable Rate (Kbps): Downstream 24468 Upstream 924
Rate (Kbps): Downstream 10015 Upstream 927

Attenuation (0.1 dB): 135 108
Output Power (0.1 dBm): 58 126
Rate (Kbps): 10015 888
Attainable Rate (Kbps): 18368 891

Damnnnnn... wish they would put them here in WC...
 
stop moaning people I am getting

Line Attenuation(Upstream) 27.5 dB
Line Attenuation(Downstream) 56.0 dB

4mb line. have to reset the router like 20 times a day.

That sucks. You should ask Telkom to drop your sync profile to 3mbps or 2mbps. This will result in a more stable connection, and you won't have to reset your router so often, or if you are lucky, at all.
 
Upstream 512000
Downstream 2048000
SNR Margin(Upstream) 12 dB
SNR Margin(Downstream) 11.0 dB
Line Attenuation(Upstream) 27.5 dB
Line Attenuation(Downstream) 56.0 dB

Well the SNR Margin have improved... but we still have to reset the router but not as much... i really dont want to go down to a 1mb...

Could it be my router? billion 400g. We have about 5 - 8 devices connected at any time... some wireless some wired.

Part of the problem could be your router, or even your ADSL filters. I would definitely replace them if they are a bit old, or at least borrow from a friend for a day or 2 (router and filters). But in all honesty it looks more like you have a terrible line, or you are very far from the exchange.

The number of devices connected to your little network does not affect your attenuation - which is sitting at 56db - extremely high. Anything beyond 60db and you won't get ADSL at all. Has your ADSL always been this unstable? I've got a feeling it was stable and fast when you first got it, but then deteriorated. I doubt Telkom would have allowed you to sign up for a 4mbps line with such a bad attenuation.

If you downgrade to the 1mbps product, you will get a more stable line, and you will also pay less to Telkom for your ADSL line rental. If you remain on the 4mbps product, but ask Telkom to drop you sync profile to 1mbps, you'll stay pay the full price for 4mbps. Might not be so bad to drop down to 1mbps, especially with the cost saving. If you ask me, I'd say you're lucky to have ADSL at all.

Where are you situated, and how far are you from your exchange? What is your exchange dialling code (i.e. your landline telephone number excluding last 4 digits)?
