Adsl latency issue still pending: Centurion

I advised that our dslam in our area are overloaded and that users need to be moved to a new rack.

To add on...you know that the moving to another rack/dslam will not fix the problem. The actual problem is that there is not enough bandwidth supplied to the dslam at the exchange and this is what is causing the latency. Think of it as an egg timer. You have a load of sand at the top but a small little hole for it to fall through. There is simply put to many customers configured on this dslam for the little ammoubnt of bandwidth supplied.

That is what is now being addressed by the company we know as Telkom. They are in the process of upgrading the equipment at the exchange to provide a larger ammount of bandwidth to the dslam so that we do not have this latency.

Timelines that I have on hand is as follows. Equipment to do th upgrade will be available on 31/05/2010. Time to do the upgrade and all cofigurations should be happening in the first 2 weeks of June.

So we should be good end of June or so?
 
+1

And TAKE NOTE TELKOM. The Exact same thing is wrong with your Pierre Van Ryneveld Ext 2 Exchange....been a year now. FIXIT PLEASE.

At last some good news again. Looks like the equipment for the upgrade has been received and installationa and stress testing is currently being done. As soon as I know more I will update you guys again.
 
Hey AcidT,

What exactly are implications of the new equipment? Will we see improved throughput en reduced latencies? And is it merely to meet demand or is there some excess capacity for future expansions also included? Thank you taking the time to keep us informed.
 
The new equipment is for expantion of the curerent ones installed. In lamens terms you are looking at ± x 16 increase in bandwitdh availability for the echange. On the DSLAM, if I can believe what I am being told, an increase of ± x 11 the ammount of bandwidth for the DSLAM. This will ammount to a decrease in latency and a better throughput on the DSLAM for the ADSL services and much less of a bottleneck.

Hope that answers the question.
 
Yep that answers it pretty well. You should go work for MWEB coz I can't seem to get a straight answer from them about THEIR expansion haha! I suppose all we can do now is wait :whistle:
It may take a while but it is good to know that Telkom do come to the party on occassion. Thanks again AcidT for updates. Please let us know (if possible) when things are nearing completion.

Kind regards
 
I will let you know as soon as I get more info...
 
Latest I have on this matter of Heuweloord exchange is that they are busy with stress testing on the new equipment. This can take some time to complete. Still waiting for more information.
 
Suppose Telkom technician strike not been resolved either. Thanks for the update. Hoping to see some improvement in throughput soon. Hard to judge where ISP shaping stops and network congestion begins.
 
At last! OMFG! I cant describe how happy this makes me. Been stuck with issues since last year Feb. This is the best news ever! (missed this thread somehow)

I got called this morning by a Telkom tech that they're working on my line and swopping me to a new DSLAM in Heuweloord. Will check tonight when I get home and post the results. (yes I have bitched alot - ICASA complaints etc - good to finally see a result of some sorts even if it isn't tangible)
 
Telkom closed the fault - line is still boned. I cry.
Escalating via Webafrica.

If anyone connected to the Heuweloord Exchange are having no more issues please just say here.
 
They can move you around on the DSLAM(s) as much as they want at the exchange. It will not help. The ammount of bandwidth on the network for the DSLAM is not enough to handle the load. This is why an upgrade is being done to provide more bandwidth for the DSLAM and the exchange. So if they tell you again "we moved you to another DSLAM or port" ask them if the equipment upgrade has been completed at the exchange before you can believe them.
 
Agreed man - was hoping it was on the new equipment. Up until now however every tech I've spoken to has said they have no plans at all to upgrade the exchange. One (I think senior) Telkom tech who calls me from Cape Town every time I make alot of waves has gone as far as to tell me that they have no plans to upgrade the exchange and its too bad for me that my exchange is over-utilized (pretty much close to exactly the words). So I haven't had too much hope up till I saw this post today. I will ask the next technician exactly what you mentioned when they call me next time though.

Really hoping this upgrade goes through soon - I play wow/bad company 2/use the line for work. Haven't been at home more than 2 evenings per week in the last 5-6 months. Connection just hasn't been stable enough to use. Would be nice to return to normality.
 
On the same exchange afaik hence my constant nagging of AcidT for info :p
FYI, this WC thing is also messing with the networks. Got a message from my ISP suggesting that they have been unable to expand their service (int bandwidth) because Telkom are reserving portions of the network for the WC services (unconfirmed though). I honestly wish we can get someone like AcidT working freakin everywhere...he is well informed and takes the time to provide feedback. Kudos Acid :)

As far as I understand it as far as reserving portions of the network is not accurate. There is a new network that was built specifically with the aim to provide extra bandwidth in the country for the FWC and when it is finished that bandwidth will be utilised for other services within the network. Reserving of bandwidth can be possible on the SAT3 and SAFE cables bandwidth that is available for international connectivity but that is only on their own services not the ones leased to the ISP's.

Thx man. Just trying to do my bit where the rest fall short.:)

They fix this? Ping tonight almost perfect (only a few packets every now and then high)

As far as I have it they are still busy with the upgrade. I also had a good latency last nigt with almost no fluxuations. I would say that the Seacom cable that is causing alot of MWEB, Afrihost and Axxess subcribers suffering and pain is the cause for the low latency as they can not connect to the net or are limited with their connections.
