Broadband setup help - phoneline

is that they may see I've tinkered with the junction box

They will know for sure a DIYer has tinkered how it is now, as you have the wires coming in from the wrong side of the IDC slots. It makes no difference to how it works, but the CW1308 cable should be cable tied to the circle bit where the old cable tie still is, then the wires come in from that side, but they would always leave a bit of slack in the wires for future changes, e.g. twice wrapped round a thumb to create a neat little coil of slack before punching them into the slots from the left side. And don't untwist the twists after stripping the jacket off.

This little shelf circled is what helps the krone tool cut off the wires, it doesn't have that shelf on the other side...

Thanks gaz - i did fix that when i paired up the blue wires but you're right - these guys a pros and will sniff the tinkering a mile off. I am happier now having discussed it on here. Thanks for your help.!

I bought the NTE5c Mk4 using the link you provided but not sure if it includes the backbox. I mesaged the seller so need to wait...
