The services of a communication network are accessed via the terminal equipments connected to the user-network interfaces (see Sect. 4.2). The term terminal equipment covers terminals for interpersonal communication (e.g. the telephone), terminals for communication between user and data processing systems (e.g. the VDU), and also data processing systems themselves. As the integration of services does not give rise to any special considerations for data processing systems, this chapter therefore deals solely with terminals enabling the human user to gain access to ISDN services.
