I assume you were attempting to plug into the satellite phone Ethernet connection??
You may want to double check the satellite phone RJ-45 interface, as sometimes equipment uses RJ-45 for serial type interfaces that require either an adapter cable or are to be used with vendor specific accessories. They may look like Ethernet, but are not.
Not sure I can help more, but here is a link for Panasonic Laptops:

Good luck.
