But i don't think i'm on any DLM. Am i wrong to think that if my linespeed is configured at 10Meg (capped), then DLM does not apply to me?
Or can you still be capped at a given linespeed, and still be on DLM with Sky?
If Sky have their own DLM, isnt this different from the BT implementation?
Stand to be corrected....

BT use RAMBO for their line management, Sky use DLM, they are different but are doing a similar job.
If your line is capped then DLM is suspended, at least for now. It may be re-activated when they do the profile changes for existing customers to the 20mb line speeds.

Re: Snr?Hmmm i'm still none the wiser with regards to why the SNR/Speed behaves this way?
This fault increases the noise on your line, to a point where the data being transmitted is lost and the noise margin, which you might look at as a safety valve, is used up. At this point your line drops and reconnects at a speed it can maintain. This speed will be below the original speed and may take some time to reconnect if the noise on the line is really bad. The line will eventually negotiate a speed and reconnect with a noise margin of around 7dbs. If the noise gets no worse, it will stay at this speed and margin. If it gets worse it will drop again and go through the negotiation process. If the line clears the noise margin will rise. Rebooting the router when the noise is high, capping aside, will increase the speed until the noise again forces the router to disconnect and go through the whole process again.
Your last resort is to try to get Sky to send out a REIN engineer. These are trained and have the equipment to detect such a fault and eliminate it if possible.

Getting sky to send a REIN engineer requires so many repetitive tests for BT to even consider it, BT send the REIN not sky.
It took almost 5 weeks on and we are still no clearer on why my line keeps cutting out in the evening, hope its REIN at least then BT will fix for you, if like myself its a issue with sky hardware/software they won't touch it and fobb you off like me.

As i've updated in my previous post; aimming to get a REIN engineer out.
Disconnects 'n Speed Issues?
Please do not make any further additions to this thread. Use the one linked above. Two threads on the same subject only serve to confuse. Thank you
