BT phone JB connections

The cables are usually colour-coded so you just match the colours. Typical colours are: Blue with white bands (speech and ringing) Orange with white bands (ringing) White with orange bands (not used but usually connected for neatness) White with blue bands (speech and ringing)

If your cables have different colours/rings then it is just a case of pairing them up.

The three wires that are the same colour (yellow in your case) are not supposed to be used as conductors at all, they are steel catenary wires used to suspend the dropwire. The orange / white and green / black pairs are the two lines.

A VM phone line is fine for SKY, unless you mean SKY Broadband of course.

thanks all, the yellow catenary wires make sense as they are hard steel, and although I managed to connect them it wasn't easy! We are thinking of possibly switching to Sky broadband. Would this cable be suitable do you think as Graham's comment suggests possibly not? I am assuming that Sky broadband is transmitted through BT cables although we have a Virgin cable coming into the house also.

All I meant was a VM line is just as good as a BT line for ordering movies etc. on a Sky box.

Sky Broadband needs a BT line, the same as any ADSL ISP.That wire is fine, as long as that joint you are making is sound, and is using a proper weatherproof box assuming it is outside.

Cheers, I bought a connector box from Maplins and it is inside the loft space so hopefully should be ok then
