i have a 100 core multicore cable and (2) excel 48 port patch panels, i have patched the 48 port patch panel into each end of the multicore, i have used blue 5,4 top right for port 1 and brown 7,8 bottom left for port 2 etc etc, i did this for the whole patch panel on both end, when i plug in an active telphone line into port 1 on the patch panel i get a dialling tone, when i try port 2 there is no tone.

it works out that port 1, 3, 5, 7, 9, 11 etc is working but ports 2, 4, 6, 8,10 etc is not working

can any1 help me with this problem need all 48 ports working

you need to split the multicore down into their bunches and terminate each bunch the same way on the panel. If you are only going to use one telephone per port you only need to wire up the blue terminals, which means you only need a 50 pair cable. If you are going to use 2 phones per port they you only need to terminate to the blue (primary) and orange (secondary). My best advice is for you to book an engineer to do it. You should have it terminated and tested withing 4 hours (if they are honest).
