OK, I think I've waited enough, couple of weeks and I bounce between 6000 and 10000 and the cabinet is fully going.
One question that does spring to mind, could my inline filter be a cause?
We only have one phone jack in this house so I thought an inline filter would work OK.
And, Well it does as such.
However it seems to me that if there are modems that can do ADSL2/2+ properly, possibly there are inline filters that also do the same.

I spose I'm wondering is are all inline filters capable of adsl/adsl2/adsl2+ and what the different versions need.
And before you start, don't hastle me about having the inline filter. I never needed a proper seperation, so if it aint broke don't fix it was my theory.

Cheers,

Hi, the common filters sold in NZ are typically well capable of ADSL2+ even if they were from older ADSL1 times, that said you may have a faulty filter.

Dont forget, the filter is only required between POTS (Plain Old Telephone service) devices such as phones, faxs alarm systems etc and the line, the modem itself connects to the direct line, ie not via the filter network. The filter is a network that will pass voice band signals but prevent these POTs devices from shorting out the DSL signal.

So if you suspect your filters are an issue then remove all POTS devices and connect your modem on its own directly to the line. If you have a BT to RJ11 line cord then you can do away with filters all together (for the test).

Purhaps you could post your modem line sync/attenuation/S/N stats etc for when its syncing at 10Mb/s and 6Mb/s.

Hi Guys,
Since my ADSL2+ cabinet was installed(erected) prior to Xmas 2008 coming online here in January 2009 my U.S International gaming has deteriorated badly. I have read the chorus cabinet install list and my cabinet reads like this....

MY CABINET
TRV Te Rapa TRV/N [2] 1/01/2009 1/01/2009 Binding 323 MPFs (Number of MPFs in that Exchange that may be affected (ie MPFs removed from exchange MDF) Hamilton City PUKETE Loop shortening plus ADSL2+ Single Bay Whisper

Can someone tell me what the number 323 MPFs means?....I'm guessing this is the amount of connections on this particular cabinet which seems high if I'm correct in my assumption? Gaming on U.S Servers has never been a problem in the past 7 years... until this blinkin cabinet was installed. Another question is...can you get ADSL2+ direct from the exchange without the installation of a cabinet? The reason I ask is my 2 brothers are gaming on the same U.S servers as me and are not getting the problems I'm getting. Now according to Telecom's cabinet map website here http://telecomwholesale.co.nz/maps BROTHER 1: seems to be getting ADSL2+ without being connected to a cabinet i.e exchange direct?. BROTHER 2: who lives close by in my neighbourhood but connected to a different cabinet has only 199 MPFs.

BROTHER 1:
Exchange Area: Melville
Show cabinets within exchange
ADSL2+ Upgrade: Sep 2007

BROTHER 2:
TRV Te Rapa TRV/D [2] 1/10/2008 1/10/2008 Binding 199 MPFs (Number of MPFs in that Exchange that may be affected (ie MPFs removed from exchange MDF) Hamilton City PUKETE Loop shortening plus ADSL2+ Single Bay Whisper

Any help and suggestions to my gaming latency problems caused by Telecom Cabinet migration is much appreciated.
Regards
Baz

Hi, MPF is metalic pair fixture, which means cable pairs or telephone connections. I would be very surprised if the cabinet is responsible for the poor ping times, more likely the plan you are on.

Changing back to the exchange will achieve nothing as the equipment deployed there is identical to whats in the cabinet except that its on a fibre extension. And the capacity of that fibre does not incur any latency compared to an exchange bound DSLAM and the capacity that cabinet is fed with (1Gigbit/s) should not pose an issue.

If you are on the Bigtime plan you may be suffering latency issues which have nothing to do with being on a cabinet.

This has been happening since the cabinet was erected...so I presume it has nothing to do with the plan I'm on. Here are my plans I've been on since this time trying to eliminate this horiffic problem which started prior to Xmas 2008...
1. ORCON MAX/MAX 20GB Plan AUG 2007 - DEC 2008 ADSL1 = GOOD
2. ORCON MAX/MAX 20GB Plan JAN 2009 - FEB 2009 ADSL2+ = BAD
2. TELECOM MAX/MAX 20GB Adventure Plan FEB 2009 - JUL 2009 ADSL2+ = BAD
3. TELECOM MAX/MAX UNLIMITED Big Time Plan JUL 2009 - SEP 2009 ADSL2+ = BAD
4. TELECOM MAX/MAX 20GB Adventure Plan SEP 2009 - ADSL2+ = BAD

My Ping seems fine when gaming but I'm getting this weird latency. Here is my ping test to xnet...

So your place to Auckland in 32mS, would suggest there is no issue with your cabinet.

Hi Cyril

The only thing that seems to change is the SNR margin on the downstream, and even then by 1.

Item         Downstream     Upstream     Unit
SNR Margin        10        12              dB
Line Attenuation 36                   16          dB
Data Rate         10547               767         kbps

Item               Downstream     Upstream     Unit
SNR Margin        11                    12              dB
Line Attenuation 36                    16        dB
Data Rate          5405                748       kbps

Item               Downstream     Upstream     Unit
SNR Margin        12                    12              dB
Line Attenuation 36                    16        dB
Data Rate          3993                739     kbps

To fix it I just keep it re-training until I get a good speed.

Hi Cyril,
I don't think I did mention it before hand in this thread.
1 phone outlet in the whole house.
It has a filter on it and there is 1 wireless phone as well as the ADSL modem attached to the filter.
Thats it.

Dare I say it a VERY basic one outlet house.

Hmmm, very odd, I would suspect the modem not training to a consistant point, if it were me I would be sourcing a Broadcom based modem (Dynalink, DSE, TP-Link) which give far more consistant and reliable operation with Telecoms ISAMs.

Thanks Cyril,
WOW, I never thought I'd hear a good word about anything with dse in the front in here.

I have had cofirmation I am on a live cabinet 4 houses away and to be honest I'm not really impressed compared to what I was getting from the exchange.
Do we know if the port optimisations done on the exchange ports are migrated to the new cabinet?

Cheers,
Terry
