Abstract: Navigational systems direct and coordinate routes through an information exchange. Through processes that monitor position and communicate with mobile ground-based systems, the navigational systems provide users with accurate information about their position and velocity. Locations may be confirmed or derived by computing differences between the time that a signal is sent and the time it is received.

Abstract: A communications system with communications terminal equipment provided with prescribed functions that are defined and controlled by a communications installation by information transmission. An identical parameter-controlled program for all communications terminal equipment connectable to a communications installation is stored in the program memory of the communications terminal equipment. All functions that can be allocated to the different types of communications terminal equipment are realized by this program. The functions provided for the respective communications terminal equipment are allocated and controlled by parameter data stored in a data memory. On the basis of an initialization in the communications terminal equipment or in the communications installation, the parameter data are transmitted for the first time to or updated at the respective communications terminal equipment by the communications installation.

Abstract: A method for transmitting equipment-specifying program parameter data from a communications installation to communications terminal equipment. The method provides for transmitting program parameter data from a communications installation to a plurality of communications terminal equipment connected thereto and is based on a message-oriented transmission protocol that is used in the sense of an information exchange in the signalling channel between the equipment. In the communications equipment, the input and output devices as well as the procedures of performance features and local performance features are essentially controlled with the assistance of the program parameter data. A transmission of program parameter data is initiated either by a parameter request message transmitted from the communications terminal equipment or by an internal request of the communications installation.

Abstract: A method for the control of voice channel attenuation for the purpose of balancing the level attenuation tolerances of individual functional units in telephone terminal equipment. A non-erasable memory location is provided and contains control data which is utilized by a microprocessor to set an adjustable attenuation element contained in the voice channel. Furthermore, the input level of the voice channel is increased by half the sum of all level attenuation tolerances of the functional units contained within the voice channel. This insures an output level of the voice channel which will be within prescribed limits.
