List of congested exchanges?

my cousin had 600ms the other day, i was looking for thread to post, but could not find it :P

he was on the dslam that was fine , which now has more users on it from the other one, so the good one is now a bit worse, not each night he says.

I am on a 10 meg exchange/dslam, but only get 4 megs cause of the card and theres no congestion at all in my area Wembley/Athlone ftw with low population using adsl than like Durban/Cape Town/JHB/Pretoria.

I think that the Main cities should get more exchanges/dslams to alleviate the problems than worry about upgrades, cause it is only going to get worse as the years go by.

I get 8-9 ms on first hop after my router yet my friend on another dslam gets erratic tracerts I suspect his line is faulty, but he claims it works fine :D dont think it is congestion unless dslams can have their separate congestion since we on same exchange (hes on 384k).

all users on Bellville North, can I have an update on the current status. Has anything improved or does the situation remain?

We have actually, since about a week ago our line has been perfectly stable at 7ms to sites like saix.net and webafrica.co.za, and that hasn't happened since at least January this year and perhaps even since earlier than that.

I guess all we can do is hope it stays this way.
 
I got information, that Belleville North has been upgraded to Metro-E as of last week Thursday 12 April. More interesting, I didn't know Telkom is willing to actually move people's lines from one DSLAM to another if there are more than 1 DSLAM in the area, as is the case with Belleville North.

So no more congestion left for Belleville North, all should be happy. In fact, I got my line upgraded to 10mbit down 1mbit up. Though it has seriously changed my SNR rates, might consider taking it down to 8mbit. Will first let it run as is for a while.

Well if your line is running at 10mbps, then I guess it must have been upgraded. Our line is still on 4096 so a telephone call to telkom is in order.
 
btw how did you get your line upgraded to 10mbps ? Or did it just happen ?

You call your ISP you have the line with, they have access via Uniweb to upgrade it, was instant for me. For you second question, didn't happen automatically, had to do it manually.

Remember though, it depends on the DSLAM you are on, DSLAM4 in Belleville North is ADSL1, so won't be able to upgrade, DSLAM5 however is ADSL2+ so you can upgrade.

Who is your line with?

Well the line and the ISP accounts are seperate. Line wasn't ordered via an ISP. The accounts we have are with WA. I guess that makes it tricky.

I suppose if we were really hard up for a 10mbps line we could order a new one through WA or whichever ISP and let them make sure it's a 10mbps line.

Regardless of all this though, I am just very happy indeed that we at least have a stable 4mbps line.
 
In that case you have to go through Telkom's call centre, ISPs only have access to upgrade lines that are ordered via the ISP and match the 3 requirements for 10mbit (adsl2+, metro-e backhaul to dslam, and Attenuation values low enough)

@4mbit stats were
SNR downstream 27db
SNR upstream 18db

@10mbit stats are (true sync now is 10015kbps down and 987kbps up)
SNR downstream 10.5db
SNR upstream 7.3db

Att downstream 27db
Att upstream 14.3db

Very happy with this result on Belleville North :)
 
Richard Hi,

I hope you are well, with respect to the Bellville North issue this has been addressed and the balancing completed. We are monitoring all the DSL traffic in the Bellville North area and are seeing the positive results.

Can you also confirm how your own DSL service has been for the last 4-6 weeks.

I am available for the next 1 hour or so should you so wish to discuss.

Best regards

order is restored in the world. just in time for D3 this weekend ;)
 
Am busy getting Pingplotter for some results as our exchange NSNG, KZN, Stanger was recently upgraded (how far i don't know) to 10MB and i sync at a sweet 6MB (perhaps someday more :p). This was over the weekend of 21/22nd April this year.

Anyway, everyday from 18:00 to 22:30 the exchange seems to get congested and no communication to any sites (80-95% packet loss) and am wondering if they still got some work to do on the exchange. In all the years we had ADSL we have never had an issue such as this but due to more users getting ADSL, i cannot say i am too surprised.

Another thing i have noticed is during the above times that my Noise margin DS drops from 14.8 (currently) to 9db and without me doing anything such as rebooting all is restored after the above times. I will provide some details from PP when i have them (any recommendations on settings is welcomed too as its the first time i will be using it).

As far as getting things sorted, what can i as a normal customer do about it? :)
 
Has anyone else been having problems with the Bellville north exchange since Friday? My internet has got unusable since then! Tested Telkom account as well as Afrihost account same problem!

Finally got confirmation.

Galloway road DSLAM's connected to Olivedale exchange are congested or broken.

Emailed them about this, this morning. They called this afternoon fixed problem. Really good service from telkom, was super surprised.
 
@Diabolix , what email address did you use and did you just send the tracert results?

For the first time since they upgraded our exchange 2 weeks ago, it hasn't gone on the frits yet tonight, normally goes off on weekends/all week from 18:00 to 22:30 around this time but will see what happens tomorrow.

I would like to have their email address handy incase i need to email them :).

+1 for Telkom sorting out the issues, we have great support on the forum too ;-)
