Incidentaly i forgot to mention, if your doing a moderate amount of connecting it well worth spending £14 on the priper idc insertion tool. the £2 plastic one is ok for one or two extentions.
Hold the tool at right angles to the block when terminating and up to 3 wirw in any IDC is ok.
With the better tool the tails, The sparebit of wire sicking out the end of the idc) will be trimmed off automatically. If your using the little plastic tool then trim this surplus off with a small pair of cutters as these tails will act as antennea if over 2-3mm and could cause snr issues on your broadband
Also any good bit of internal telephone cable or CAT5 will have some cotton running up it. to strip the cable snip up and along the outer insulation with small cutters for about 5-10mm then idealy with long nose pliers grip the cotton and wrap it round the end of the pliers a couple of times. then if you pull the cotton back it tears though the outer insulation easly without dameging the wires in side, and give your self 100-140mm of internal wires to play with.
Check you havent damaged the wires when stripping back
and snip off the end 5mm of intenal wire which was the bit which was initaly exposed when you cut the outer insulation back to expose the cotton.
When tidying the wiring up before closing the block terminal or putting the socket on its pattress/back box. Dont coil any spare wires around the cable or coil the wires in little loops, again to avoid snr issues. instead loop everything around 2 fingers and squash the loop you've made into a rough sausage
Phew, i think I've covered most of it, anything I,vw written dosn;t make sence, please let met know. The number of times Ibvw read back what I've written and thought whaaa...?
