Below is what I get from my router on my 2 meg line. ADSL router not far from tel connection, has an ADSL micro filter. Telephone line is clear, no crackles or pops etc. I assume I have no choice to call Telkom and get them out to fix this problem and there is no easy/quick fix? :confused:

Connection Status - Connected
Us Rate (Kbps) - 512
Ds Rate (Kbps) - 2048
US Margin - 14
DS Margin - 11
Trained Modulation - ADSL_G.dmt
LOS Errors- 0
DS Line Attenuation - 57
US Line Attenuation - 31
Peak Cell Rate - 1207 cells per sec
CRC Rx Fast - 2
CRC Tx Fast - 0
CRC Rx Interleaved - 0
CRC Tx Interleaved -0
Path Mode - Fast Path

It generally just means your copper length is very long and doubtful Telkom will do anything about that. Best is to just wait and hope they upgrade your area and connect you to a new MSAN.
 
My stats are almost identical:


ADSL Parameters Uplink Downlink
SNR Tolerance（db） 12.0 12.8
Attenuation（db） 55.0 31.5
Rate（Kbps） 2048 512

And no, there's nothing that we can do until Telkom decide to pull finger. And I mean the other one - not their usual...
 
Zoid is right - too far from exchange. Not much you can do.

You can or should get 4 meg judging from your stats :p

lol how do you figure that? His 2meg is already throwing errors...how is he going to get 4 meg stable?:confused:
 
57db attenuation should be 4meg with a proper router and some hacking....

SNR Margin (dB): 4.3 12.6
Attenuation (dB): 59.0 32.7
Output Power (dBm): 0.0 6.8
Attainable Rate (Kbps): 4684 940
Rate (Kbps): 3627 507
 
In the same boat as well ...

SNR Margin (dB): 9.3 6.7
Attenuation (dB): 57.0 35.2
Output Power (dBm): 0.0 12.8
Attainable Rate (Kbps): 4500 652
Rate (Kbps): 3259 615

Even then don't get your hopes up, being in an MSAN area has nothing to do with whether you are connected to one. Telkom's deployment planning is favouring density instead of reach.

Upstream from my 'end of the line' SDC are two SDC with MSANs, each progressively closer to the exchange. The closest one being ~1800m away from my SDC (as the road goes). Do you think Telkom would put in the effort to re-route/cross-connect the long suffering users on exterme distance SDCs? Not a chance, I've tried every contact I have and always land up getting a toffie.
 
@Roman4604: Are those two SDCs with MSANs in residential areas or are there a number of offices nearby? Were they passive SDCs previously or were there other cabinets there before? It seems to me that Telkom is predominantly targeting offices and not upgrading residential areas. In the UK residential connections far outnumber business connections so I wonder if this strategy will be profitable in the long run.

The one closest to me is purely in a residential area, no office parks in its immediate vicinity. And yes it used to be a passive SDC before being upgraded with a co-located MSAN.

The other closer to the exchange is also in a residential area but surround with a few small shopping centers.
 
How many customers in the residential area do you think have signed up for the 20 and 40Mbps services?

No way to tell exactly, I suspect they cut over all ADSL customers terminating on that SDC (MSAN ports I believe are capable of supporting ADSL1 - VDSL2).

What I dont understand is in a low density suburb like mine, why are they targeting those SDCs close to the exchange? The SDC in question could probably support 4-10Mbps service without an MSAN, by virtue of its reasonable distance. On periphery SDCs like mine you can barely manage 3Mbps (and thats with a good understanding of what modems work best). I think most of my neighbours are on other technologies like HSPA/iBurst due to the slow/poor speeds.

If Telkom wish to gain xDSL subscribers more rapidly, there's a case for the outside-in strategy rather than the inside-out one I'm seeing in my area. After all whats more profitable, gaining a whole bunch of new 4Mbps-40Mbps, or just upgrading a few 4-10Mbps to 20-40Mbps.
 
Eventually every one will be cut over to MSAN/ISAM .
Exchanges and street MSAN/ISAM it is a change in technology .

The idea is to move an entire exchange area onto MSANs and then scrap the switch and related equipment back at the exchange. So there may be a few MSANs within the exchange area that are less viable than others but it needs to be migrated to achieve a full central office conversion.

Not entirely true... some areas are not even remotely viable and may even get switched off!!!

I understand that, just not the sequence in which its being done.

Just guessing, but I recon my SDC terminates more dwellings then the one closer to the exchange with the MSAN. And as mentioned, that closer SDC shouldn't have the attenuation issues my 'end of the line' one does. So why upgrade SDCs without great need first, instead of ones which would derive much more benefit (& potential new connections)?
 
Well, I took the plunge and called Telkom to see what they could do. I have to admit, Im surprised by their service. I was expecting to wait ages...

I reported the fault last night. Got a call this morn near 10:00 to ask for more details. Woman said I will be contacted. 30 mins later, guy phones me just down the road from the house saying all measurement are fine there, he is getting very little noise so cant understand why its so high at my place. Asks if someone is home and will go check it out...

Very pleasantly surprised at their support...I was not expecting much at all. Lets hope they find the problem and can fix it ;)

Well done on the response for support Telkom!

There are many reasons for that .
Availability of electricity for the MSAN/ISAM
Way leaves from council.
objections from the public.
Traffic considerations because of the height of the unit
Just to mention a few

The way it works is the outside MSAN/ISAMs will be cut over in an exchange area then the exchange will be cut over ,bascally an MSAN/ISAM in the exchange or simultaneously .
If it is not done like this then some of the lines will be cut over twice .

Wow - again. Just got an sms the fault has been fixed. Will see when I get home tonight if it indeed has been fixed, but yoh...top notch service. #amazeballs

Possible but unlikely. Electricity & traffic certainly wouldn't be a problem and I don't recall Telkom every publicly asking for approval on MSAN builds (in my area at least).

My query precedes this, how do they decide which SDCs to initially build MSANs next to. So far evidence shows they don't saturation build an exchange area in one go. For instance the Fourways exchange which I'm on, probably services 50+ SDC, however only ~10 of them had MSANs built next to them in round one.
