SPN/A is now offering VDSL to ISP records according to Voyager/Snap, so you should now be able to get reprofiled.

No change to SPN connections though, despite it being the exchange :(
Still speeds of 0.4mbs and below anytime after 3pm with many timeouts when browsing. These disappear completely with connection speeds of around 5-6mbs at 4am .

Hi 

I know where SPN/A and SPN/F are and the exchange.   I have not seen the  SPN/B amd SPN/C cabinets.
Are they part of the exchange?

I assume that they do SPN/A because  there are more users?  I think the plan has SPN/B and SPn/C being done at some stage .. would have though that they would have just done them all at the same time?

Hi pjays,

Yes I think they're completed in a kind of number of users served order. Also I think they may need to physically change the cabinets for SPN/B/C/F I've seen SPN/C and it's very small. Which means new concrete base and power etc.

SPN/C is on the Chorus grandplan for 01-04-2014 completion

Hi optrex,

I've got a good idea where you are from your posts, can you PM me with your physical address, as I'm wondering if there's another way to get you a faster connection.

Hi Pjays,

FYI

This is SPN/C:
https://maps.google.co.nz/maps?ll=-43.68653,172.435961&spn=0.001635,0.002411&t=h&z=19&layer=c&cbll=-43.68653,172.435961&panoid=X82aBg-813TlK6tBZUydmg&cbp=12,109.81,,0,7.41

This is SPN/F:
https://maps.google.co.nz/maps?ll=-43.679225,172.353116&spn=0.001666,0.004128&t=m&layer=c&cbll=-43.679387,172.353382&panoid=CEGeRAiQQc9NRw2m_7UuOQ&cbp=12,62.17,,0,12.85&z=19

And I can't find any reference to SPN/B, so can't give you a line for that.

Hi DiverChris

Thanks for the info. I was looking for it in the wrong place.
This now ties in with the Chorus maps and their coverage.

For someone like me, who does get ADSL access just, I would have thought that an upgrade to SPN/C would ultimately mean more capacity for the ADSL1 users left? Like me. So prior speeds which were up to 3mb maybe attainabble (with the lessor number of ADSL1 connections? )

Hi Pjays,

I'm making an educated guess here, but the kit in the existing cabinets is old Conklin gear and the limiting factor is the E1 backhaul i.e. the connection from the cabinet to the chorus backbone (main fiber/s) in the SPN exchange. An E1 connection is 2mbits/s in "size" and the Conklin's can support up to 4, but rarely have more than 2 i.e. 4mbps, this was the situation with SPN/A before the weekend.

I'm very close to the SPN/A cabinit, so my ADSL1 sync speed was max (nearly 8mpbs), bur i could only ever get about 3.5mbps this was because the was the maximum of the backhaul 2 x E1 = 4mbps less the upload speed of 0.6mbps = 3.5mbps.

After the weekend I now can get max sync speed for ADSL1, as they haven't changed the profiles to ADSL2+.

All well and good, but where does that leave me I hear you ask.

Well E1 connections run over twisted pair copper and some of these have been freed up in the SPN exchange with the upgrade of SPN/A to fiber. A few months ago I was in discussion with Telecom and Chorus (via Telecom) re. the backhaul being flooded, and he requested some bandwidth traces from me to prove the lack of it especially in the evening. Now I'm sure my discussions had no bearing on the SPN/A upgrade, more the fact that the cabniet was full and there is a new subdivision being built. But there may be an short-term fix for SPN/F where they could add one or more E1's that used to serve SPN/A, if you understand what I mean.

Sorry it's a bit longwinded. Maybe PM with your contact details and I can tell you some more.

Perhaps someone can make sense of this reply I keep on getting from Chorus (quoted), because it makes no sense to me at all.




I am currently on the Springston Exchange (SPN) DSLAM: SPN-DSLAM-01

I understand SPN is a Minsi ASAM in the form of a 7300 Alcatel DSLAM with 4xE1's, 4*2M upstream (for a total of 8M) but its shared among 161 customers

This means that during peak flow we are routinely only achieving download speeds of 0.3 or 0.4Mbits/sec, especially between 16:00 and 23:00

It sounds as though the backhaul might be getting flooded, during the day at weekends, we can achieve 1Mbits and at 4am it can peak at 5Mbits, but there should now be some free-up with the completed rollout of fibre to SPN/A, which is fed from Springston exchange to alleviate the peak congestion.

It would be very useful to know the expected upgrade path for SPN. Ideally an notification on a migration to ISAM or even an upgrade of the ASAM to a STM1 (155M) backhaul.

Details are available for upgrade path to SPN/C and SPN/F but with 161 customers on SPN and the exchange feeding the cabinets, we need to get the bottleneck resolved as speeds of 0.34Mbits on average when required are not acceptable.

If there is no immediate plan to upgrade SPN then this request needs to be escalated as its an ongoing problem that we have suffered with for some time.

Unfortunately you are outside the Chorus coverage area for planned network upgrade.

The Rural Broadband Initiative (RBI) has been developed by the Government to help enable urban like broadband services to be accessible to rural residents. Under the Rural Broadband Initiative, Chorus is responsible for connecting rural schools to ultra-fast broadband, while Vodafone (the Government's other partner in the programme) has the primary responsibility for enabling broadband services to 80% of rural households by deploying wireless broadband coverage.

While Chorus is continually extending the reach of fixed line broadband, the significant additional investment costs involved in deploying new broadband infrastructure to some harder-to-reach areas makes the economics very challenging.

I recommend that you check with Vodafone on whether their community broadband coverage plans include your area. They have published some indicative coverage maps on their website and plan to make this service available via a range of retail service providers: http://www.vodafone.co.nz/broadband/wireless/


Basically they are upgrading all the cabinets that feed from my exchange, but not the exchange itself, so I end up in a residential hole of ADSL1 surrounded by paddocks with ADSL2 and VDSL or I can go to wireless to get a service upto 5mbs (which is what I should be getting anyway). Or am I missing something?

Hi Optrex

I finally got a response from Chorus

At this stage an upgrade for your local broadband cabinet/ Exchange remains outside of our current plans. We can’t make any promises about the future, but we do review our plans each year.....

From this you would assume that nothing is going to happen to SPN for a while..?

Voda have apparently done or are in the process of doing a cell tower upgrade at lincoln which may now be of benefit, using 3G dual carrier. I should know more next week, but fingers crossed because information coming from sales indicates faster speeds.

I'm now on voda rbi and have been for a week

The good:
I've got 6-10 Mbits/Sec http traffic download with 2.5 upload

The bad:
I was promised install within 7 days
7 days later, they said the account had been approved and my install would be in 3 weeks.
The install itself took over 6 hours - this included 30 mins pushing the van off next doors waterlogged lawn. Yes they went to the wrong address then were stupid enough to park on the grass after 3 months of rain had fallen in 2 days.
They then took an hour out to fetch their tools from the last job (where they had left them)
Then a bloke sat on the apex of my roof in the dark for 3 hours with no safety gear, while the guy inside directed him towards the strongest signal - left a bit, right a bit, hold it. Tighten it up, no its gone again. Hang on thats a different cell number. etc etc, before sliding his way back down again to the ladder that was waiting at the guttering - even the roofers demanded scaffold when they were up there!

Then to cap it off, my approx 500mb data per day manifested itself to anywhere between 1.5gb and 3.5gb per day over 4 days. 10gb gone just liek that!
Mad panic and I reverted everything back to my equipment, using the supplied SIM router as a bridged modem only ( usage dropped back to 500mb ). Voda as yet have not admitted liability or acknowledged there may be a problem with their router.

When I rang them up they said to wait for my bill and then invoke a "bill shock" procedure where they can adjust the pricing! WTF ?

Anyway, was it worth it? I have to say probably not. I'm still waiting for an FTP upload of 18mb to a server in CHCH to complete. Thats taken 30 mins to upload while I've typed this, and I still have 3mb to go.

Would I recommend the service? As it stands at the moment, definitely not.

what's the latency like?  does christchurch routing go via auckland?  that upload speed sounds shocking for ftp.. but http traffic went way faster?

Interesting. Install sounds diabolical, but presumably that's just an issue with Vodafone rather than anything inherent to RBI itself.

Initial figure indicated decent speed but the your FTP transfer seemed very slow?
