Well, the BT engineer called. I cannot divulge his name, but let's call him MC.

He was truly brilliant - nothing like the horror stories I read about BT engineers at all.

MC first called me on my mobile to let me know he was arriving in about 15 minutes. He did.

MC then disconnected all my stuff, and done some tests with his gear. I had a bad line.

MC then replaced the face plate, done same tests - bad line. He told me the equipment showed him there was a fault about 120 metres away indicating the green box (now painted grey).

He then went outside to the green box (now painted grey) for an hour.

MC said he think he found the issue, and proceeded with all the tests again. This time they passed,. but MC said he wasn't happy as my line should be better.

MC then said I will go outside again and check.

15 minutes later MC returned and said he will try something else.

He re-wired my phone line to use two different wires (i.e. my face plate now has the ground and ring bell wires connected).

MC done the tests again. All passed with flying colours

So all along, it was so fault in my line between the box outside and the green (now painted grey) box up the street,

Here is my stats graph - a bit busy:

A little improvement, don't you think?

Sorry to go on... but I am still hanging on this super speed even at lowly SNRM. Never, ever had such a good connection:

ine Status:Connected
DSL Modulation Type:ADSL_2plus
Annex Type:Annex A/I/J/L/M
 	            Upstream	Downstream
Current Rate (Kbps)	1023	9664
Max Rate (Kbps)	        1024	9665
SNR Margin (dB)        	6.8	0.4
Line Attenuation (dB)	22.2	42
Errors (Pkts)            0	0

Don't like the low NM. Discon could be imminent.

Nope, stayed up all night, no disconnects! The lowest SNRM up got was 0.4!

Nick

I thought it was tailing off on the graph, at least it's hanging in there.

It virtually hit 0, but the connection hung on in there.

Here is the full graph from over night:

Remember, it is all on the same scale, so what a difference since the line got repaired!

well previously you had higher snrm so its hard to see if was a huge actual improvement. Because when the sync speed went up the snrm also went down.

Well, I know that I never, ever connected above 7mb before in 8 years on this line!

Anyway, after being connected at that rate for 48hours (and SNRM dropping down to 0.2 sometimes!), the line just dropped and reconnected:

Line Status:Connected
DSL Modulation Type:ADSL_2plus
Annex Type:Annex A/I/J/L/M
 	            Upstream	Downstream
Current Rate (Kbps)	1051	8384
Max Rate (Kbps)	        1052	9016
SNR Margin (dB)	         5.8	8.1
Line Attenuation (dB)	22.2	42
Errors (Pkts)	        0	0

I guess this is the DSLAM doing it's stuff over my 10 day training period.

I am still well happy though - never had such a good connection

Looks like changing the pairs did the trick - your line is performing really well now

Its stuff being reconnecting when it senses router has discon'ed when NM no longer tenable. Nowt to do with training but normal operation.

Still your stats are good and let's hope it don't keep dropping NM too low.
