Recently moved into a new house and have got WorldxChange broadband up and running*.

I currently have two modems at my disposal, 1 x D-Link 502T and 1 x Dynalink 1320. I know for a fact the 1320 is a ADSL2 modem but not sure about the 502T. From what I've read the 502T can be upgrade via firmware to become ASDL2 compatiable. The 502T has been updated to run RouterTech custom firmware that greatly improve what is normally a terrible router/modem.

Both the 502T and the 1320 currently only connect to the exchange at 640/7616kbps, which seems suspiciously close to the 8mbit limit of ADSL1. The 502T is currently set to multi mode modulation which results in the modem connecting using ADSL_G.dmt (ADSL1?) and when I try to force it to connect using ADSL2 modulation it wont connect.

I've had the 1320 connected at a previous location using ADSL2 on Xnet's network, so when I moved into the new house I simply changed the username and password but as with the 502T only connected at ADSL1 speeds.

I've got both the phone and modems connected using filters and have tried using different jacks to see if that makes a difference. I've got relatively low pings and line attenuation, so I can't find anything that suggests the connection is crap.


I've also checked the Telecom Wholesale website and both the cabinet and exchange have been ADSL2 capable since May 2009**.

Is there anything I can do to try and connect at ADSL2 speeds? Do Xnet need to 'flick' a switch?

Thanks


*Originally tried to connect up with Slingshot took them two weeks to tell me there supposively isn't a phoneline at my house, Telecom and Xnet got it all working in three days!

** Also notes that my cabinet is VDSL capable, any ideas when normal pleebs will get access to this?

1:  What does the 1320 show the line mode as (Status > DSL Line)?
2:  What are the rest of the line stats (attainable line rate vs line rate, attenuation etc)?

If I recall correctly, I think Xnet's non fusion plans are based on UBS (Telecom Wholesale product), which may be limited to ADSL1 speed ie: 8Mbit.  Maybe someone from Xnet can clarify?

Crap! I think your right I've just read the Xnet website and if you read between the line it does say you need their fusion plan to get full ADSL2+. Bit of a crock really, Xnet should definately make that clearer on their website.

Interestingly the Telecom wholesale UBS product is being grand-fathered in July this year (which means no new signups to it) and withdrawn in 2011 so surely they (Xnet) must have a plan to switch users of standard ADSL to UBA.. you would hope!

Someone from Xnet may be able to clarify/comment if they see this thread.

Hey found out some more about this, Xnet don't have any control over the line rate you connect to the exchange/cabinet at.

Most likely there is a problem with the port config for your line at the exchange/cabinet. I would log a job with the helpdesk to take a look at it, which will probably result in a "port reset" or the config for your line at the port in the exchange/cabinet being re-done.

It might be academic given they limit throughput on their standard ADSL plans inside their network though which is sad.

Looking at your profile it appears to be set to ADSL1 speeds,  you are connected to an ISAM which is capable of ADSL2+ speeds. 

Configuration Information

CPE Type:
dlink

DSL Type:
non.shdsl.opermode adsl.gdmt.aa.no, line.type.pots, latency.interleaved

Line Id:
RUE_Y-DSLAM-01:1-1-5-43

Spectrum Profile:
HSI-ADSL1-LP

Service Profile:
HSI-I-FSFS 

This may be due to someone previously having problems on the port.  I can log a ticket with Wholesale to request they change the Service/Spectrum profile.  It's currently set to ADSL1 Low Power as you seem to be very close to the exchange.  We could request it be changed to HSI-ADSL2-AM which is a normal power profile (there is currently no Low Power ADSL2 profile).  However this could introduce a problem as it's likely it was changed to a Low Power profile for a reason.   If you're willing to give it a shot I can go ahead and request the change, if you're prefer to wait until your plan is capable of ADSL2+ speeds (see below) we can hold off.  

The other information in the thread is correct we limit Flood, River & Stream to ADSL1 speeds,  however we are reviewing this and it may change in the near future.

hi Cameronn

Thanks for the reply, great to get a response straight from Xnet. If my plan isn't ASDL2+ then there seems no real point to connect to the ISAM using an ADSL2+ profile. Its just as easy to wait until/if the plan become ADSL2+ capable. Until then I will keep an eye on the Xnet website.

Thanks for the help.

My understanding of ADSL2+ is there is only 1 power setting which is "adaptive". That is what the "+" is supposed to be about (the "2" is double bandwidth/spectrum). Power level is dynamically adjusted to maintain a good connection while minimising crosstalk with other lines, allowing other lines to also attain a slightly higher speed.
