You have 2 options here for the (XXX) section. Option 1 is to see if
your panasonic pbx supports a T1 interface, and is afordable for the
number of lines you wish to connect via asterisk. Or you use a FXO/FXS
solution to connect the 2. Since it is easier to get FXO ports for
asterisk right now than FXS ports, you will want to connect a FXS port
of the panasonic pbx to a FXO port on the asterisk machine. So you
probably want to get X100P cards in the number of lines you wish to be
able to connect to the far side.
