WayneS: 18July

Installer ran new cable (house 60's) to replace old black cable. VDSL modem reasonable connection. Installer talked about issue in the cabinet.
But had a couple of calls this morning from Telecom checking to see how my VDSL was going. Apparently the works order showed that all was installed okay. Seems to lack of communication between Chorus & TC..
Awaiting further ...


WayneS: have just had a call from Telecom that the exchange/cabinet they connected me to yesterday does not support voice, only VDSL. It was news to her.. and TC doesnt support naked VDSL



Well back today for another go ... This time voice all good but no ADSL/VDSL. Installer called at 4p to tell me it would take up to 2hrs to come right. After calling faults about 7pm and spending close to an hour on the phone was told sorry cant help and we will have to wait until tomorrow.

How can this be so hard??

Um, what, their telephone exchange\cabinet doesn't support voice!?

The "lack of communication" thing seems to be a pretty common problem though.

"2 hours to come right" probably means "shrug" as you should get a DSL signal instantly if things have been configured at their end I would've thought, although it might take a while to actually log on and get internet access.

Given that it took the guy over 20 minutes trying to perform a factory reset on my Telecom supplied modem, which I ended up doing myself via the web interface when he wasn't looking as I got sick of him pissing about, I suspect some of them may not be too clued up on the tech beyond running the cables.

It can take a bit of to & fro with them to fix things sometimes, took me 3 days to get my ADSL up and running initially as they were pointing the finger at user error, it turned out they hadn't done something in the cabinet.

Apparently they needed to install a mux as the cabinent only supported naked vdsl. They have made the necessary changes over the last 3 weeks .. It was new to the TC staff that I talked to. Who always very helpful. It just took a while to get to the right people.

Talkiet:
1cf2: Had my vdsl installed on 1 August. 700 meters away from cabinet, speed so far is 10m/36m. dlm 4

How can I connect to dlm 1?


It's not something you can choose like on ADSL2+... You have to wait, and refrain from rebooting your router or disconnecting the DSL line as far as possible.

It can take weeks for DLM profiles to change. The automated system constantly evaluates if you are on the most suitable profile. (Note, most suitable is NOT always the same as fastest)

Cheers -N



I am on DLM 1 now, after 10 days evaluation. ping local speedtest server is 0ms now, so happy.

Hi there,
Firstly I would like to thank all the experts for freely providing their time and energy in answering and providing information for the forum members. Your knowledge is greatly appreciated.

On the 30/07 I had VDSL installed by Chorus at my residence and my plan is with Telecom. The Techincolor TG589, RJ45 connector and Splitter were installed and the technician described this as a perfect installation as everything was installed at the ETP point where the Telephone cable (black thick one) entered my premises from the street. He made a phone call and advised that everything was operating correctly and the up/down speeds were ~9Mb/30Mb. We then checked the Modems DSL Connection web page and the figure was 9,864/30,288 of course I was happy with this as it was an improvement over the previous ADSL connection of 0.9Mb/13Mb. It is now over 10 days since it was installed and the figure is now 10,342/32,844 which seems ok to me, of course a higher dl would be nicer :-)

I used Telenet as explained in the Thread to find the following information from the modem -

So I hope that is enough information for my questions below -

1/ Does the quality/condition of the cabling on the phone side of the splitter (the side that connects to the rest of the phones in the house) impact on the performance of the VDSL side of the connection?
2/ In the modem information above the Delay [ms]: is 0.00 is that correct?
3/ The speedtest on Telecom's site returns a Latency of 5ms so does that mean I'm already at DLM1?
4/ I spoke to a Chorus engineer and he said I was only 350M away from the DSLAM however with the Attenuation level from the Modem information above it calculates to be more like ~900M, is there a reason for that amount of discrepancy and could it be (realistically) fixed by Chorus? - I know that's a pretty loaded question so be kind :-)

I would like to thank you in advance for any help and or advise. Just to let you know that I'm an Electronics Engineer of 30 years experience and have a pretty good Telecommunications background however VDSL and its performance peculiarities is not an area I have knowledge of.

Cheers,
Bruce

Have been connected for 26 days now and had rest on the first day and no more resets.
Is this normal or is there a problem with the dslam?
Speeds are very good with not many line errors
35-42 down 9.8 up 36ms ping to telecom speed test.
I think i am on dlm-1.
Thank you

It's not so much a matter of not supporting voice, it's that it doesn't have a direct copper MPF back to the NEAX for voice.

There are many cabinets where the copper MPF was deemed to be on it's last legs and abandoned. This means the voice from the cabinet uses a VMUX solution or the ISAM-V cards if you are with a provider that can offer Baseband IP voice services. If you want a full list this is available on the Chorus website.

In the early days of the cabinetisation project NEAX based POTS voice was never going to be a supported scenario going forward, all voice was going to come from the ISAM-V cards in the ISAM.

Ultimately I pick a mass migration of Telecom customers to the ISAM-V cards anyway as their new NEAX voice cards mean they could theoretically minimise the number of exchanges that they require.

A little off topic, but has any provision been made for analog modems in this instance? The most common one being eftpos terminals, but also analog modems for remote administration of equipment (when you're a third party contractor it's a lot easier to plug something to the phone line than to convince the IT guys to let you go through their IP network)

Low speed data works fine over a VMUX connection, it's purely a VoIP connection between the cabinet and NEAX using so is no different to any other TDM connection. Baseband IP will depend entirely on what your VoIP provider / Telco wants to offer.

Support for low speed data services are the reason why Telecom have to be careful what they do in the voice space. The TSO says they still need to support them.

The simple reality however is that low speed data services are history and anybody relying on them needs to be looking for alternatives now before they end up like alarm companies relying on cheap alarm concentrators in denial that they'll ever need to move to IP.

Got installed this morning. This is the result of speed test with the computer connected to the modem by ethernet. Pretty happy with this, especially the up speed!



Unfortunately I can't keep it hooked up that way. I had the modem installed on top of a bookcase in the middle of the house, for best coverage. The computer (an old Mac Pro) is in a room almost directly above, and is not wireless capable. I had a usb wireless adapter plugged in which worked great for an hour, then went nuts and started flicking the network connection on and off every couple of seconds. So I am currently trying to work out some better options on getting the signal to the computer than trailing a 10metre ethernet cable down the stairs and across the living room! Ideally I need a decent network expander that can join the wireless network and then connect to the Mac by cable. Any suggestions?

1) Cable is a better solution. 

2) Try to change wireless settings on router, for example switch off 5 Ghz N and switch on A/B/G 2.4 Ghz mode. Just play with the wireless settings. 

3) http://www.pbtech.co.nz/index.php?z=p&p=NETAS3053&name=Asus-RT-N53-Dual-Band-Wireless-N600-Router--2.4-GH   (Maybe something like this) 




Sorry about my English guys :>

I would love to be able to cable, but without ripping off some walls (which were recently redecorated at great cost) it's not likely to happen. Thanks for the suggestions, I will check them out. I've posted a query over on the LAN thread too, so fingers crossed something will do the trick.

Thank you, have added that to the list. I'm going to try to self-install an AirPort Extreme card, but I'm keeping options open in case I can't manage it :)

Just signed up for VDSL on 150GB plan :D

Fingers crossed for good speeds!
