Just some pics i took of my house wiring

Where line comes in downstairs (black box), then into the white box

Inside gubbins

Inside black box

 

[tang0]

Upstairs adsl from downstairs

Inside ADSL faceplate

Diagram

Yep, but i didn't get a lot of help really, i emailed isp they didn't say a lot

 

[tang0]

thought id already had told you that looking at the those photos the line comes in upstairs at the main socket with the nte 2000 and goes downstairs to the other sockets

Yeh whats the best way to bypass all other wires so i can just plug in adsl straight to the incoming line?

 

[tang0]

you need to take some photos from outside so i can say where the line definatly comes in. but im almost sure it comes in upstairs and then goes down so the adsl filter should be doing its job and nothing needs disconnecting

Right this is what i think, the line comes in, goes to the black box, then goes to the bt box, then routes upstairs next to faceplate pc i think this is the master socket, and all other lines in the house are filtered off this.

 

[tang0]

so when you disconnect the faceplate upstairs do all of the extns go off?

hmm not sure i'll have to try
