Abstract:
The invention relates to a circuit arrangement for the integration of EDP systems in the use of telephone installations which are connected to the public ISDN or Euro ISDN telephone systems. The aim is to connect a telephone installations to an EDP installation in such a way that all the functions of the EDP system can be used during the use of the telephone installation. This aim is achieved by using a circuit arrangement consisting of: the telephone sets (2; 11; 13) which are directly connected to the public ISDN or Euro ISDN telephone system (1) via a line (a) and an intelligent telephone installation (3); and an integration component (5) which is arranged between the intelligent telephone installation (3) and the personal computers (4; 12; 14), on the one hand receives signals via the SDLC or ISDN connector (8) by means of line (b) from the public ISDN or Euro ISDN telephone system (1) through the intelligent telephone installation (3) and send signals back to the public ISDN or Euro ISDN telephone system (1), and on the other hand transmits a set of data having suitable information via line (c), an LAN (9) which is connected via line (d) to the LAN server (10) and line (e) to the personal computers (4; 12; 14) and receives the set of data back from the personal computers (4; 12; 14). The conversion of the signals into the set of data and vice versa is performed by the integration component (5) via a computing system (6), a software layer (7) and an SDLC or ISDN connector (8) with internal software.
Abstract:
A communication apparatus connectable to an ISDN network and having a voice communication function and a data communication function comprises a memory for storing a destination number in a speech mode, an instruction unit for instructing data communication in the speech mode, and call means for calling based on the destination number stored in the memory in response to an instruction from the instruction unit.
Abstract:
A method and system for wireless communication between a moving vehicle and a remote server through at least one external mobile network are disclosed. The at least one exterior mobile network provides at least two concurrently useable data links. The method comprises: providing at least one router in the moving vehicle for receiving and transmitting wireless data communication to and from a stationary communication server outside said moving vehicle through said at least one exterior mobile network; evaluating the quality of said data links on a host layer by repeatedly sending requests arranged to trigger a determinable automated response to said stationary communication server via said data links, and measure the time until the triggered automated responses are received; and assigning data streams to said data links at least partly based on said evaluated quality.
Abstract:
Von einem Ursprungs-Kommunikationsendgerät (KE) wird mit Hilfe einer Kommunikationsvermittlungsanlage (KA) ein Verbindungsaufbau eines durch eine Wahlprozedur bestimmten Dienstes zu einem ebenfalls durch die Wahlprozedur bestimmten Ziel-Kommunikationsanschluß (KAN) eingeleitet und überprüft, ob dort ein den betreffenden Dienst realisierendes Ein- oder Mehrdienste-Kommunikationsgerät verfügbar ist. Bei einer Nichtverfügbarkeit wird mit Hilfe einer erweiterten Verbindungsaufbauprozedur ermittelt, ob aus einer vorgegebenen Gruppe von Diensten ein den gleichen Dienst realisierendes Kommunikationsgerät (KE) sowohl am Ziel- als am Ursprungs-Kommunikationsanschluß verfügbar ist. Sind entsprechende Kommunikationsendgeräte (KE) verfügbar, so werden diese dienstgerecht verbunden, sofern die entsprechenden Kommunikationsendgeräte (E) nicht bereits durch vorhandene Kommunikationsbeziehungen in dem diensteintegrierenden Kommunikationsnetz belegt sind.
Abstract:
L'invention concerne une technique utilisée avec un système de communications de RNIS (réseau numérique à intégration de services) permettant à un ordinateur central, lequel exécute une session d'ordinateur central avec un utilisateur et est connecté par le système, de changer dynamiquement un chemin d'accès RNIS, connectant l'utilisateur à l'ordinateur central et acheminant la session de l'ordinateur central entre ces deux derniers, entre une connexion commutée par paquets et une connexion commutée par circuits lors du déroulement de la session, afin d'établir la connexion particulière la plus adaptée aux nécessités de communication d'une tâche exécutée pendant la session, par l'ordinateur central. Un tel changement dynamique du chemin d'accès du RNIS est sollicité par l'ordinateur central, n'interrompt pas la session de ce derneir et n'est pas ressenti par l'utilisateur.
