[quote author= BT Wholesale]CIDT will be rolled out to most exchanges by June 2012.
Problem is I can't find any definition of "most"
PS. When I mentioned the Avg SNRM plotting, I was meaning the DS SNRM as the US is normally flat on 20CN unless there's a sync drop (as per last post).

Edit: Oh, and as far as "evidence" goes, there is plenty already.
1) Tell them you want an experienced faults agent to look at your problem, you are fed up with responses from agents that don't know what they are talking about 2) Tell them to look at the DLM Profile Data 3) Attached an extract from the modem/router logs to your ticket 4) Attach the largest example of CRC burst to the ticket 5) Attach sync plots with drops to the ticket and possibly SNRM ones as well

After many fault reports and engineer visits I finally got one who did a thorough job and switched the pair from the main cab to the exchange which looks as though it has fixed it (now on 21CN uncapped upstream with no problems).
I refer to the main cab because my connection is odd
It goes from the exchange to a distributor cab (there aren't many houses near it) and then to other cabs scattered around then to the properties.
Just to add - my drops were cause by loss of upstream sync due to errors and often it would resync with a lower upstream speed with a noise margin of 6dB
Whether this is relevant to your problem I have no idea

What has surprised me is how long after we finished messing about the DLM did it's thing again!

I've also upgraded to 10.2.2.B this morning.

I've seen that before on a 20CN line with an imminently failing E-side prior to its collapse - the way it would sometimes be smooth and suddenly switch to spiky mode.

Something really odd about the interleaving on. It's synced with a 6.6dB margin where it always used to be dead on 6 and I'm seeing the highest sync speed I've ever seen on this line.
Increased noise margin and sync speed?
