Part of the reason I use a 66 block to terminate Panasonic cables is that I have the flexibility to change my jumper field at any time and open it up for testing. If you put an 8 port digital card or hybrid card in the same slot, you need to grab every 3rd pair starting with pair 2 for a digital set. If you then put in a 16 port card, you grab every pair for the first 16 and cross connect it to the second pair of every station.

It sounds like you are going to have to rewire your patch panel :-)
