What generally happens with a spare pair, are they even connected up at the cabinet or do they connect right through to the exchange?

Spare pairs go as far as they go, spares within internal wiring very rarely go beyond the external feed to the property.

..... and you don't tag a pair in the back of a socket any way, you tag it on the 66, or the DP ????

We are in agreement All a little odd.

Placing a resister on a pair at the far end on a new build is a well known method for newbuild. Jointers can then confirm what dside is going to what house using a meter and measuring the value at the cab without the need for tones or labels.

Newsite planners will often specify spare pairs at houses rather than stumped pairs at underground distribution points.

In this case a second pair has been planned to this house.

It is not something that a BT or contract installer will be familiar with. It also will have no bearing on broadband speeds.

I'm impressed. Most jointers will be confident of their schedule and thier jointing and won't be putting resisters on. This is a professional network build. The resister confirms spare pairs are going where they should be and records are correct.

It has no place being there, end of.

Nonsense. If you don't know what it is, hold your counsel and wait for someone that does before stirring up the punters.

Can't say I've ever seen this in gals work with bellway housing. Interesting...

I still don't think it should be there. It seems like a typical situation of builders taking measures into their own hands and history has proven quite well that builders are not BT openreach engineers & often provide sub satisfactory internal wiring.

Lets not forget this is behind the master socket faceplate and its BTs property, so whatever the builders are doing should be to BT spec. If a BT engineer doesn't know what it is then in my view it isn't meeting BT spec.

OK, thanks for the top advice there.

Thanks again for your help.

Not had any disconnections past few days and my DSL Noise Margin has settled between 58 and 68.

Think the ADSLNation faceplate has helped

That's good news - it does seem that you were perhaps having issues with the filters that you were using previously, SNRM only varying between 5.8dB and 6.8dB (58cB and 68cB) is very good
