A big meal of it. Rather than worry about which 3 zarjaz said, just connect all 6 cores on the NTE5 frontplate

...... shame theres only four IDC points on the OP's frontplate .....

Interesting, I have one with 6. But the number matching principle still applies

After a bit more digging I found the green/white-green pair of wires behind the master - was worried for a minute that I didn't have them.

My master socket front plate does indeed only have 4 connectors on it - 1 and 6 are missing. Still, I think I know what I'm doing now so I'll give it a go as soon as I can get a wiring tool.

Thanks to everyone who helped me with this - appreciated.

The Openreach badged NTE's they have finally admitted that greens were never more than spares, so just have 4 IDC terminations on the rear of the frontplate. In fact the new internal wire being installed has only two pairs, and has gone back to the 'old' colour codes..... blue/orange and green/brown.

Greens (pair 3) were / are used on a lot of PABX systems for featurephones.

Yes, I know that, thank you Jon. But it's only going to 'fog' the waters if you start mentioning stuff like that, in this respect.

Interesting. I think that the 3 pair cable is more satisfactory for pulling, but the extra pair never seems to have been any use.

Does the new cable have a new spec no or is it still cw1308?

Still CW1308, it's available in a number of different sizes (ie. numbers of pairs).

Thanks. Found it on RS. 2 pair appears to be back to the old colours, whereas 3 or more stays the same as up to present.

Update: The very latest batch of NTE's now have IDC terminations for the incoming pair, rather than the traditional screws. And now only have three IDC points on the frontplate.

Interesting that. Could you please give the appropriate colours for IDCs 2,3,4 & 5?

Thanks.
