Abstract: The invention allows automatically multi-booting a computer. Each functional mode of a computer having at least two operating systems installed is associated with one of the operating systems. Functional mode information identifying a particular functional mode of the computer is stored by a recovery system. While starting the computer, a boot loader receives the stored functional mode information, selects the operating system associated with the particular functional mode, and activates the selected operating system for the computer.

Abstract: The present invention discloses a network control device (CPS) for controlling data transfer in a first network (IP), wherein the data transfer is supplied from a second network (SCN) via a switch device (SD) adapted to control the second network (SCN) and an interface establishing device (GW) connected between the switch device (SD) and the first network (IP), and said network control device (CPS) controls the interface establishing device (GW) by using signalling associated with the first network (IP). By applying the network control device according to the invention, a gateway between the first and the second network can easily be installed.

Abstract: A multilingual operation and maintenance interface for a telecommunication exchange. The interface includes a plurality of modules and a plurality of resource files. Alphanumeric information in a different target language and related to interactive communication with the interface is included in a resource file. At least one resource file is an intermediate language file including intermediate language information other than alphanumeric information in a target language. An external device is provided to display a control response of the operation and maintenance interface in the target language.

Abstract: A method and a system for controlling the operation of a telephone exchange from a subscriber connection. A direct communication connection is established between a subscriber connection and a telephone exchange control unit. One or more command macros executing a predetermined task with associated parameters are supplied from the subscriber connection to the telephone exchange control unit. The commands of the given command macro are executed in the control unit under the control of the parameters associated with each command.

Abstract: A centralized command system for a telecommunications network, in which system a central exchange of a telecommunications network and network elements, such as local concentrators, under its control form an entity which is controllable in a centralized manner from the central exchange by means of user interfaces of individual concentrators. The system includes a program command structure in which the command sequences required by each task and directed to the central exchange and/or one or more network elements are combined so as to form a single logical task entity, or macro, on the basis of which the system automatically initiates embedded terminal sessions with the necessary network elements and executes the commands necessary for performing the given task.

Abstract: A network management system for configurating and reading data and states of several network elements, such as telephone exchanges, of a telecommunication network by giving the network elements commands according to their internal command language when at least some of the network elements of the telecommunication network have mutually different internal command languages includes a memory for storing parameters describing the command language of each network element, a generator for generating service requests (Rq) in a network element-independent format, a converter (21, 22, 23) for converting the network element independent service requests into commands according to the command language of the network element which is the target of service by using parameters describing the command language of the network element, and a sender for sending the generated commands to the network element which is the target of service.
