Maybe the Draytek just isn't up to the required spec. There are a lot of very specific requirements and warnings about what isn't supported and what is.

That was the sort of thing I was meaning in my previous post - rather than warning about possible repercussions.

In reply to a post by RobertoS:

The specification of hardware/firmware requirements for approval for when connecting non-Openreach kit once they permit it can be found in BT SIN 498.

The xlsx files contained within the zip file are interesting.

What are they & where was the data obtained?

The QLN graphs seem to suggest that QLN is actually worse on shorter connections (unless that means we have been misinterpretting QLN graphs to date).

The theory to date has been that QLN at around -140 dBm was 'quieter' than say -120 dBm.

In reply to a post by Chrysalis:

I am surprised noone else has noticed, but the line appears to have not been DLM'd what you pasted shows fast path with a low snrm so seems neither banding or interleave is in affect.

It simply looks to me the draytek is just syncing poorly on your line which isnt too surprising given it has bad reports with openreach dslams.

The bit I cant explain is your higher pings, its possible the modem is misreporting the fast path status.

What do you mean by not DLM'd ? The line was definitely interleaved before and it became worse after the installation, i believe, due to the fact i had to switch between the HG612 and the 2860 multiple times.

My Broadband Ping the tbb Quality monitor shows the ping jump up many hours after the installation.

I'm told that the 2860 resolves the issues that Draytek were having with low speeds on VDSL .... if it doesn't then it's going back !

Just looking at my current graph and it looks really horrible:

My Broadband Ping

Lots of spikes and it looks like three interleaving changes down and then back up .... i'm wondering if this is going to be a dud ..

Put the Openreach modem back in and see if that helps.

agreed, the draytek modem is a fail on uk FTTC.

the hg612 needs to go back in, and just use the draytek as a router not a modem.
