Hi

There is also a transformer on the input stage.  It isn't killing VDSL, all working well here :)

Regards

I was wrong, it is rejecting common mode in the vdsl band which is good.  I did not read the spec properly.

The B10A is the unit intended for the UK. 
irrc the other is for parts of continental Europe such as Germany?

Am I still able to obtain one for £35 from the kind Kitzien mentioned previously?

Eclipse have a few but if I can save a bit then that would be helpful.

If you mean dmcdonnell I think his supply of F1000's has dried up :( 
The F1000 is basically an Eircom branded VMG8324-B10A, which he was able to unlock and put standard f/w on.

Last time I looked Eclipse was the cheapest place to get them.

Just to say that my 8924 has been running now with no interruptions for nearly 37 days (probably tempted fate now  ;) ) so I inclined to believe that my issue was at least exacerbated by logging (now turned off) probably using too much memory. I'm still running 10C0 for now. I might try 11C0 soon but while it works I dont want to change anything right now.

my 8924 has been up for 37 days now on 1.00(AAKL.10)C0 of the firmware.  During that time i have not had any line drops but did have one reconnect on the PPPoE 15 or so days ago but i guess this was initiated by the ISP?  The GUI has generally been stable but there are the a few bugs that are noticeable.  It sometimes reports that I've lost connection to the ISP/internet but this is not the case.  It also sometimes shows the WLAN as being down but again this is not the case as these are visible and usable on the network.  These issues are more annoyances rather than anting else and i have been happy with the general performance so far.

As Chrys says, its the reduction in SNRm that causes the loss of speed.

When a new line gets attached, the crosstalk generates more noise on the line which causes the SNRm to decrease and that in turn causes the reduction in sync speed.

-----------------------

If you are using DSLstats, then you can spot the signs of a cross-talker coming online.  You can sometimes even see when one of your crosstalkers has a resync or reboots their router.

For example heres my DSLstats SNRm graph and you can see that at about 1:20am one of my crosstalkers had a resync.   
Note how my SNRm momentarily goes up to 7.8 dB when he's not using his connection.
Then look what effect it has on my connection speed and how the max attainable jumps up.  This particular crosstalker 'costs me' 5Mbps of sync speed.

Hopefully it's ok to drag up an old thread but I have an update.
I have had the Zyxel since the middle of last year and it has been faultless but my line speed as been steadily dropping off as can be seen on the attached which i am guessing is due to cross talk as already mentioned. i am using version 8 firmware and my speed has dropped from around 38 Mbps to now around 32 Mbps. Is there anything i am doing wrong or that looks wrong from the attached please ?
i have DSLstats if there is anything i could post from that.
Apologies if i should have started a new thread.
Thanks

If you don't already, you may want to use DSLStats to upload your data to https://www.mydslwebstats.co.uk/

You may also want to try an updated version of the firmware - the 8324/8924 is now up to v.14 - and may now include newer broadcom code than v8.

Thanks for the reply, i have updated the firmware to version 13 as i could only see version 14 for the 8324.

I had a look at the link which looks good and i have found the 'My DSL Stats' part of the DSL Stats program so i will register. There is a wealth of information that it would be handy for those in the know to have a look at.
As i was one of the first to get VDSL out in our village i would imagine there are a lot more users now than when i joined.
The only other thing that has changed is i have added cabled CCTV into my house which also  uses wifi to talk to alarm sensors and i also have the power cables for the DVDR recorder running near to my router cable running from my front door via my loft to my Zyxel upstairs.
I'll register for the My DSL Stats and report back.
Thank you

The 8324 and 8924 are identical apart from the 5ghz wi-fi on the 8924, they use the same f/w as ZyXEL only show the 8324 on their sites as the f/w is the same.

I also would be careful about v14 until we know more about it as it is still not on any ZyXEL site I can find.

Does this sync higher than the HG612? Thinking about replacing mine.
