Hey i was looking through my billion 711ce configuration and found the snr:
ADSL STATUS
ADSL Line State: SHOWTIME
ADSL Modulation: G.dmt
ADSL Annex Mode: ANNEX_A
ADSL Startup Attempts: 1
Elaspsed Time: 0 days 0 hours 19 minutes 42 seconds
Downstream Upstream
SNR Margin 17.9 12.0 dB
Line Attenuation 24.9 16.0 dB
Errored Seconds 1 3
Loss of Signal 0 0
Loss of Frame 0 0
CRC Errors 1 3
Data Rate 8128 896 kbps
Latency INTERLEAVED INTERLEAVED
Are these reasonable number? I am quite happy with my data rate, but not sure about the snr and line attenuation, what are good numbers?
Thanks
For a 8mbit line those stats are perfect.
SNR of 17 for downstream is well above the required 10 for a stable line, same goes for the 12 SNR on upstream. You should have a perfect line, as long as your exchange is not congested, most ISPs should give you a very very nice experience, especially on the capped accounts which is not limited to a specific account speed.

SNR ratio is your line strength. The more the better. Too many joints, old telephone wire and noisy neighborhoods can bring down your SNR rates.
0-10 - very bad
10-20 - little bad
20-30 - good
30-40 - excellent
40-50 - congratulations, you live right next to the exchange
Attenuation is the distance from your home to the exchange. The lower the better and it means your closer to your exchange.
Different plans show different SNR rates. So if your getting 30db on 256kbps-2048kbps connection, You may get 40db on a 256kbps unlimited connection. So be sure to mention your plan.
Here's mine:
Plan : 256kbps / 2048kbps
SNR Margin (dB): 34.4 down / 18.3 up
Attenuation (dB): 24.5 down / 11.5 up
wrong post, sorry
Can I get 4Mbps?: here's my stats, Telkom says I can only Get 1 Mbps according to their system.

Gees, those are some of the best snr margins I've ever seen!!! Fibre Optic unless you live across the road from the exchange..

I think the DSLAM is other side of his wall or something.

I have a similar reading :
Channel: FAST, Upstream rate = 512 Kbps, Downstream rate = 4096 Kbps
Link Power State: L0
Mode: G.DMT
Channel: Fast
Trellis: ON
Line Status: No Defect
Training Status: Showtime
Down Up
SNR (dB): 30.2 27.0
Attn(dB): 10.0 6.0
Pwr(dBm): 11.2 12.1
Max(Kbps): 12256 1212
Rate (Kbps): 4096 512
But when I ask telkom for a 10mbps line they say the exchange only supports 4mpbs.
You'll also notice that your modem is currently connecting with G.DMT modulation. Once it changes over to ADSL2+ modulation, only then you might be able to get 10Mbps.
I'd say be glad that your exchange is still only running at 4Mbps, because I've seen too many issues in areas where Telkom is allowing people to connect at 10Mbps.
That should be fine for 4meg connection

Please help!!! Why are the Stats so bad???
We wer always syncing at 4mb fine but now after a fault was fixed its dropped and is not stable ?? :'( Please help
PM your number I can check if your exchange is 10 megs if it is its your dslam card which hasn't been upgraded like mine.
My dslam/exchange is 10 meg after confirming tests when my card blew Thursday while testing other cards in box.
They were on modulation ADSl 2+, but I am still using an old card so I only get 4 megs/g.dmt, cause it wasn't working on the new cards, since it gave only gave me 512 kbps and 10 db for downstream or I would have used new card.
So be happy you using old cards since they work better atm till they can get one which is compatible with your old card.
