	connected to LAN	connected to station

	it may be that the DESNC also have a speciall encryption-chip.

	who has information about the hardware design of the DESNC?
	how do the KDC communicate with the DESNC (e.g. data link service
	or transport service or ?)?
	which parts of the iso-protocol are encrypted?
	what is the price?
