panasonic kx-tda100 with 85 phone extensions

Hi everyone, I need help setting up my Panasonic kx-tda100. I am required to connect 85 phone extension lines. We have also procured 4 pieces of KX-TDA1178X (MCSLC24) extension cards which I think are appropriate. We also procured DTA 204X Amphenal cable that connects from the extension card (MCSLC24). I am confused about how to connect the phone extensions to the PABX. Can someone please guide me on how to connect the PABX to the telephone extensions and what hardware I need to install in between the PABX and the phone extensions. This is for the hotel where I’m the IT Engineer. I look forward to your suggestions. Thanks
