Hi There!

I went away on holiday for 5 days and have come back to notice my Siemens SX763 WLAN DSL Modem has significantly dropped in connection speed. Before I went away I was getting connection speeds of around 8-9mbit's but since returning I can see we are at around 2-3. My Speed Tests were coming back at 7-9mbit before I left and now struggling to get 3mbit. Nothing was changed to my knowledge while I was away, though I am told cabinetisation will occur in my area on the 11th of Jan 2011.

To be fair in the last 6 months I have dropped slowly but surely from what I was getting 11-12mbit connect speeds and 10-11mbit effective speed tests, down as far as 7mbit from time to time.

Would this be something expected during the approach to Cabinetisation? Also I have had about 3 disconnects of PPP since I got back 18 hours ago.

I am loathe to call Orcon because they have such average support these days, I am hoping it's a known issue.

I am on the blockhouse bay exchange.

Interestingly, my last reboot seems to have bought back my speeds to 6500/960

Status:
Cable connected

Line mode:
ADSL2+

Maximum line rate:
6504 kbps (downstream) / 968 kbps (upstream)

Noise margin:
29.1 dB (downstream) / 32 dB (upstream)

Line attenuation:
33 dB (downstream) / 25.7 dB (upstream)

Output power:
18 dBm (downstream) / 9.9 dBm (upstream)

Most likely a result of preparations of converting to a cabinet.. Had the same problem when I was with Orcon, though you are lucky to know when it is expected- they had no idea I was going to be cabinetised. Unfortunately you might find a significant drop in performance (even more than it has dropped now) due to interference between the cabinet and exchange- assuming you are on orcon's own LLU network.. you'll have to either go telecom wholesale with orcon or change providers to someone who will do wholesale for you

Rest assured that if I don't keep the same speed, I'll be moving elsewhere very promptly.

Interestingly I have been speaking to them today and they said I am scheduled for april 2011 for cabinetisation, which would mean this isn't a normal outage. They are sending out someone.

Good luck :) I had to ask for someone 3 times and they never sent anyone :P Update here if it gets resolved!

Ok there is something weird going on. I did an isolation test and couldn't get connected at all. If I plug in a phone I can get connected. I have a properly split jackpoint (no filters required). Periodically I have lost my connection and the only way to connect is to dial a number on my phone.

Something is weird there, those noisemargins are massive. Could be that you have ended up on some strange profile as part of the move to the cabinet or similar.

Still nothing happening around the cabinet here thats due to go live in april. The old small box has finally been taken away, but not seen any action with the new one, and I go past it most days.

Well I had a look at my wiring config. Transfield came onsite 18 months ago and at my request put in a dedicated splitter, interestingly there is a filter connected to the jackpoint labelled ADSL and my router is connected to it. I removed it, and my connection speed jumped 2Mbit but my connection was so unreliable I replaced it with a new filter I had lying around. connection seems stable at 6mbit but that is a long far cry from the 8mbps I had a week ago or so, and a far far cry from the 11mbit I had 6 months ago.

I think the wiring is screwy in my jackpoint. You should not need a filter if you have a separate jackpoint.

If I removed the face, can someone tell me what the config Should look like inside? I suspect what they have done is made both jackpoints identical!

I'm impressed, wonder if they got decent staff to cover the xmas break. All we seem to get is closed tickets.

Sounds like a miswired/faulty splitter.. no, they dont look the same and to go into detail on the wiring of the splitter you need to have a basic understanding of how it all works... if you wire it wrong you can make it so that your phone doesnt work at all (let alone get a dsl signal) without wiring it correctly... Get them out, it should be covered if they did the work.

Hi There!

An Update for you.

Orcon were out yesterday, slightly ahead of the 48 hour timeframe they gave me, and found a problem outside my house, on the wall cabinet thingy. Replaced the entire box, getting 6mbps on g.dmt, dead stable. I called Orcon and asked to be put back on ADSL2 profile which the guy gladly did, 7.3 megabit, then I thought I would change the Orcon CPE for a Zyxel one, and I am up at 8.8 megabit dead stable.

The tech explained the reason for the double filtering is that for some reason my cpe came with a rj11 to rj45 cable and the jackpoint was BT, I have since removed it and found a BT to RJ11 for my new CPE and we are away!

In the end reasonable marks for Orcon who delivered what they promised. My line noise margins are 37/27 varying to 42/27 still. Wondering if there is anything that can be done to improve that?

When Cabinets are installed (Now confirmed as April :(( ), how do I go about being put onto one? The tech who came out yesterday, said he went from 2 megabit to 17!

I had some basic understanding that unless you were <4Mbit they wouldn't move you to a cabinet?

Be aware that the Tech waxing on about how great the cabinets are, will have been a Telecom employee/subcontractor.

If you are on the Orcon LLU, you will be disappointing by the cabinet. Your ADSL will go bad and you may need to be "re-bundled" to a Telecom wholesale service. If you are re bundled you will loose the value for money you presently get (Gb per $, caller id, voice mail etc for free etc). You will get premium speed, but you will pay premium prices for it.

This is of course the whole point of cabinetisation - to head off network competition.

Telecom will claim that is is not, and their lobbyists will harp on to the Comcom about better broadband for all New Zealand, but multiple points suggest otherwise:

1) Unbundled exchange areas (ie, the best served areas) were cabinetised first
2) Telecom spent little money on improving ADSL for years but post LLU they have quickly got them selves deep, deep in debt to pay for break neck paced cabinetisation.
3) The areas on NZ that have no ADSL at all or where the exchange has run out of ADSL ports should logically have been the first choice for cabinets but today they are still crying out for something better than dial up.

The areas in point 3 above are the first to get the nationwide broad band upgrade, because the guy's running that project know full well that Telecom is more concerned about thwarting the competition than serving the customer. The project would have never been required in the first place if this was not the case. This is also one reason why Telecom lost out in the very first round of tenders to implement the project.

Oh well, that's my soap box - sell Telecom shares, look for a non Telecom sourced internet option, if there's no alternate, share via wireless with you neighbor and 1/2 your costs.

To be honest, I would gladly pay some extra to get some extra.

I fully understand the concept behind cabinisation but I also know as a business owner, that the process telecom are undertaking to protect their investment isn't unreasonable. It's just not nice if you aren't benefitting.

What I don't think people understand that is Telecom is a business, no a charity, and therefore they are entitled to protect thier shareholders returns by doing things which benefit the bottom line.

I would prefer to stay with Orcon, but I certainly won't if my speed drops as a result of the cabinet in my area.

Theoretically, from what I understand, Orcon are supposed to switch you over to something wholesale if you request it, once cabinetised.. Don't quote me on that cause I couldn't get them to do it for me so I did have to switch

You may see it that way, and I am on an unbundled exchange for both orcon and one of the other 2 that do it (SS or VF) and I am not getting my cabinet till april if they stick to schedule.

I dont think that anyone who is stuck on 3 megabit would be complaining like you are about it being to eliminate competition.

Stop being so myopic and thinking that everything that telecom does it about screwing over the other ISPs - they have all being screwing telecom over for long enough by bleating to the commerce commision and getting the govt to force telecom to allow them to freeload in the profitable areas.

Interestingly enough I was a big proponent of them splitting telecom up, but working in the IT industry and seeing what getting an adsl line provisioned is like now, and how much harder and less reliable everything is, I wish they had left it alone. At least in the "bad old days" at least you could get reasonable service from Xtra :) Now everyone is equally crappy.
