Hello,

I inherited a Panasonic D308 Hybrid system. It was pulled from working place. It is capable of 3 CO and 8 extension.

I am new to the phone system.
I want to set it up at home office. I am stuck at 2 places.

The 25 pair connector cable & 66 block are connected. I am trying to connect the wires from a phone jack to the 66 block. I can not seem to get it to work.

I used the blue pair to connect on the 66 block as well as the jack.

I tried different combination of the twisted pair, but I can not seem to get it to work.

Can someone tell me how I should connect the twisted pair, what color I should be using, can I use just use 1 pair?

The 3CO jack is for 3 incoming phone lines. I do not have any phone plug that uses 3 pairs, I have 2 pairs for phone lines and 4 pairs for cat5.

Can I use the phone plug for this? How should I assign the color of the twisted pair wire for the phone plug?

Thanks for your help.
