I don't think I had interleaving applied on the HH5A - is there a way to check from the HH event logs?

My understanding is that while the HH5A didn't support G.INP as it has the same chipset as the ECI modems, this was fixed via a firmware update that BT rolled out.
Unfortunately, there's no way to tell with the HH5A as it doesn't report interleaving or errors or much of anything useful.

The firmware update didn't fix anything to do with G.INP, it was just an incremental fix for the EU directive on power saving AFAIK.

As others have said the max attainable figure goes skewy if Interleaving (or more correctly Error Correction) has been applied. 
We are uncertain why this is, but my guess would be that its something to do with the overheads required for FEC.

FEC overheads aren't part of the sync speed, yet the modem still has to transmit those overheads on top of line speed.   If we work on the basis that FEC overheads are circa 12%* and you are syncing at 40Mbps, then in all reality you are pushing 44.8 Mbps down the line. - the extra is hidden from view but theres a couple of different methods in how that overhead can be transmitted.... and how much is subtracted from sync or sent via a reserved channel or frequency (too long of an explanation for this post).  Its that overhead which seems to confuse the max calculation on some routers.



*12% is an average, but it can be more depending upon the INP value set by DLM

I believe I can hear noise on the line when doing a 17070 quiet line test buts its intermittent..

Once G.INP is enabled on your line the DS errored seconds will drop but the US errored seconds will still be visable as it will be on fastpath.

G.INP to be active on a new line like yours could take weeks or a month so please be patient  :)

FWIW telnet current states...

Many thanks for all your replies - on reflection, I don't think I had interleaving with the HH5A-simply as the link never went down until I replaced it with the HG612

Looking at the line stats (in the post above) it states:

Quote
Interleave depth:          1      1
INP:                       0      0
G.INP:                     Not enabled

which from the helpful interleaving guide on the main site means (I believe) I was also on Fast Path when I connected the HG612

However, I was remotely disconnected this morning and it looks as if the exchange has applied interleaving.

My line currently reports:

which is the first time I have ever seen the max upstream over 18MB (or a reference to Upstream rate = 10000 Kbps)  and the download max attainable speed is similar to that of the HH5A.. - not sure why the line didn't go straight to G.INP though..

I would post some graphs (some can obviously see them online on the my dsl stats website) but havent been able to get HG612 Modem stats to play with XP (it refuses to schedule a task)

PS: not sure it impacts matters at all but am using a MK3 master socket but the only change to the line was that I had caller ID enabled in the early hours..

Hmmm. That's odd as the programs usually work very reliably with XP.

Are you receiving any error messages when attempting to create the task?


I wonder if it could be that your firewall and/or AV program need to be told to 'always allow' the programs.

You could test that by attempting to run each program in the Scripts folder manually.
Windows might then ask you whether to allow them or not.

When I try and create a task, it asks for my XP username/password. I originally didn't have a password on the system and it didn't like that. I added one and still get:

Quote
There was an error creating the task, the task will not be created.
Its possible you didn't enter the username or password correctly.
If you choose to cancel than the task will not be created and the logging program will not run

This machine is just running the standard Windows XP AV/firewall - no external ones. Running the scripts independently suggests they work - its the username/password bit that is stopping me..

A password isn't actually necessary for HG612 Modem Stats on a PC that doesn't need one to log in to Windows when booting up.

Maybe you could remove the Windows password you have recently added, reboot the PC and then ignore the password request when trying to create the task.


It shouldn't really make any difference, but is it XP Pro or Home that you are using?

Sorry for the delay in replying - real life got in the way.

I have tried to download the software from scratch to try again.

I still get told its the wrong password (I don't have one now - its been removed) when trying to create a task and get the error message "The task "HG612 Stats Program" does not exist." if clicking on the red scheduled task does not exist button.

Have you tried simply leaving the password blank?

If you don't use a Windows username either, have you tried leaving both username & password blank?
That worked for my brother-in-law the other night, but he is using Windows 7.

Yes - it complains that some things might not work without a password - lets me continue and then I get the same erroe.

It won't accept a blank user name - and insists on populating it with the name of the Admin account

Would it not be simpler to manually create the task, just name it "HG612 Stats Program" and the GUI will detect it. It needs to run the "HG612_Run.exe" program which is in the scripts folder every minute.

This could be related to the issue referred to here:-

http://www.techrepublic.com/forums/questions/access-denied-on-xp-scheduler-xp-pro-sp3/


I initially didn't suggest manually creating a task in an attempt to troubleshoot/understand why the task couldn't be created via the GUI.
It's not a problem that I have been alerted to previously, but as some users do still use XP machines, it would be most useful to find a resolution should it ever happen again.


My only other thought (at the moment) is that it could be the general Windows User Access Control setting being set too high on gt94sss2's PC.


If all fails then yes, setting up the task manually may be the answer, unless manual creation is also prevented.
In which case, the suggestions offered in the link I posted above may assist.

All,

Thanks for the continuing suggestions. I think we are getting closer to solving the issue. When trying to create a scheduled task manually, I get an Error 0x80070005 at the last stage - which I think is the issue Bald_Eagle1 identifies in the link above.

I found https://support.microsoft.com/en-us/kb/904423 but the Hotfix won't install as its already in included in SP3 so need to try and find another solution

Of course, the longer term answer is to try the upgrade to Win7 on this machine (a Samsung NC10) but I can't do that atm..

At least we know it's not a fault of the GUI, the way to automate task creation in XP was fairly limited IIRC, so it didn't give much feedback error wise.
