Did you snip of the last couple ml on the wires prior to termination in the new NTE ?

If not done, you will be making a potential HR as the wires reconnect in exactly the same place as before.

I think that was already done when the engineer fitted the original NTE. The A & B wires don't touch at the end.

Just used the phone and it caused no adverse effect.

I think he meant snip off the end where the wire had already been in the IDC, so that you are not punching down on the exact same bit of the wire.

It's good practice to cut the cable just below any previous crimping.

I suspect I didn�t make myself clear.

I *think* you have purchased a new 5c and replaced your original 5c, therefore having to reterminate the wires at the back. If so it is good practice to snip a couple of ml off the end of the pair, this way the V metal component will �bite down� on fresh wire rather than onto an already indented spot.

If this isn�t what you have done, I apologise for the misunderstanding.

Yes, that's correct. I didn't snip any of the pair, because I was concerned that I may cause a fault if I did that.

That�s the one.

It may cause a fault by re-crimping used wire.

If you were going to the trouble of replacing the Master Socket I would have gone with an NTE5A + MK3 combo.

The newer NTE5C's are very poorly made.
A decent IDC punch is only a few £

I'm sure I'll get gasps of disapproval on this forum but an indecent one is only a few pence and, at a pinch, a pair of deftly wielded flathead screwdrivers will do the job. That is probably considered really bad but if you are only doing a couple of wires in a home setup and don't have the right tool to hand...
That said I did get a plastic one many decades ago for various phone line extensions and it lives to this day in my man-tin alongside a roll of solder and a radiator valve bleed key. Things no self-respecting DIYer should be without.
