If I was to declare my working hours it would dissuade anyone from entering IT as a profession

Thanks but I was after it as a function of attenuation so that when someone presents their router stats you can work out if they are actually getting a reasonable speed.

IMPORTANT: We are basing speeds on generally worst case, i.e. being as honest as possible so as not to set expectations high, i.e. impact of bad crosstalk is name of the game. In essence we expect people to be above the figures given in the vast majority of cases. The use of three power masks means you can get different speeds as the power is cut back to not kill ADSL2+ speeds in the bundle, which may explain some variations. A cunning plan is underway to increase the data we have on the speed/distance side.

Distance to cabinet (metres)	Downstream Attenuation (dB)	Estimated downstream connection speed	Estimated upstream connection speed	Cumulative %'age of premises at this distance
100m	5dB	100 Mbps	25 Mbps	5%
150m	10dB	80 Mbps	20 Mbps	10%
200m	12dB	65 Mbps	18 Mbps	20%
300m	15dB	45 Mbps	17 Mbps	30%
400m	16.5dB	42 Mbps	16 Mbps	45%
500m	18dB	38 Mbps	15 Mbps	60%
600m	19.5dB	35 Mbps	14 Mbps	70%
700m	21dB	32 Mbps	11 Mbps	75%
800m	22dB	28 Mbps	10 Mbps	80%
900m	24dB	25 Mbps	9 Mbps	85%
1000m	26 dB	24 Mbps	8 Mbps	90%
1250m	28dB	17 Mbps	5 Mbps	95%
1500m	33 dB	15 Mbps	4 Mbps	98%

If this passes the test of peer moaning, then can commit to the site pages

I don't know my downstream attenuation (don't have an unlocked modem) but at an estimated 600m line length your estimate for downstream is about the same as BTs (although I get between 40 and 50 throughput depending on what DLM is up to) and the upstream is more hopeful than BTs estimate of about 9Mb but pretty much spot on for what I actually receive.

Lastly, what are the 18-month contract get out costs likely to be at any given point?

Full price list including early termination costs.

Takes a while to get used to the layout of the list, so make sure you don't pick up a wrong figure .

Hmm. I forgot about the up-to on the upload. There's always something.

Yes :-/

Line attenuation (dB):  	21.1		0.0
Signal attenuation (dB):	Not monitored		
Connection speed (kbps):	57775		11487
SNR margin (dB):        	6.0		5.8
Power (dBm):            	12.6		7.1
Interleave depth:       	8		4
INP:                    	47.00		47.00
G.INP:                  	Enabled		

RSCorr/RS (%):          	0.0006		0.0077
RSUnCorr/RS (%):        	0.0000		0.0000
ES/hour:                	17.7		0.21

Thanks.

wow those are super conservative numbers

They are very conservative, aren't they? Better than being over-optimistic but they seem to be allowing for masses of crosstalk. When vectoring comes (if it ever does) they will hopefully be revised.
