Looks that way. I just went through the forum and gathered all the IPProfile reports I could find and added them to the ones I've seen. There was one instance of 38718 being reported http://forums.thinkbroadband.com/fibre/f/4054740-ftt...

The smallest gaps seen so far are 1,2,4,9,10,19,31. This isn't a comprehensive list but there doesn't seem to be potential for a pattern to emerge. I'm going to keep and eye out for new IPProfiles and add them to the list. I agree though, it looks likely that a 1kbps scale is used.

Cheers MHC, can't edit post above so I'll put the list on pastebin and update it there. http://pastebin.com/nj58TZac

I had 38717 for the first few days on 8c without interleaving, which then got DLM'd to 34799, with interleaving.

When I first swapped to 17a, the IP Profile was 38716, without interleaving.
We then had a burst of errors, so DLM put interleaving back on. The profile is now 38714.

I imagine it is caused by rounding errors, based on exactly how many tones are used, in which frequency bands.

Just to update my previous post of 38710k , I had a drop in speed for a couple of weeks down to about 35Mb (didn't record profile here), but now it has increased again and I am on 38718 k.

On 8c profile I had full 38717, now on 17a and on 38716.

This is exactly what I have seen with my connection.

Thanks for posting that again I missed it on my first scan. Added to the IP Profile list. Your also only the second person to report a profile of 38718.

I saw a drop to 33-35 while on 8c and the change to 17a restored full sync again, that may explain your drop and subsequent restoration of sync.

Just though you would like this:

IP Profile for your line is -38399 Kbps

No problem, I wonder if there is a link with the equipment used for the cabinet and modem, as I also seem to be the only person on the forum running an ECI modem instead of the Huawei.
