Multicore cable and 48 port patch panel

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
