What do you need to do with it?? I've set it up a few times and its pretty easy. All I've ever done is run a normal programming cable from the system to one PC thats connected to the LAN. This PC is normally a dedicated PC for use as a CTI server. Install the Panasonic TSP driver on that PC and then you should be right. To test, I usually use a program called phone.exe that you can download from julmar.com for free.
After that a server version of the CTI software has to be installed onto the CTI server, and then every other PC that uses the software will get a client version that connects to the CTI server for information.
Hope it helps a bit....
