An apparatus and method for a data commmni- cations device to selectively operate in a plurality of analog and digital modes, including as an analog mo- dem (762), as a digital modem (774), and as a temmi- nal adapter (794). The embodiments provide for a sin- gle, integrated data device to be con- figured and also subsequently reconfigured to provide for data communication over a variety of networks, in- cluding public switched telephone networks and digital networks, including Tl, El and ISDN. The various em- bodiments also provide for signal simulation (370) of the various networks, such that the actual coupled network is transparent to a data temminal transferring information through the data communication device to the network.

L'invention concerne un appareil et la technique correspondante aux fins d'un dispositif de transmission de données destiné à fonctionner de manière sélective selon plusieurs modes, analogiques et numériques, y compris en tant que modem analogique (762), modem numérique (774) et comme adaptateur de terminal (794). Les modes de réalisation portent sur un dispositif unique de transmission de données intégrées, dispositif à configurer et à reconfigurer par la suite, également, pour assurer des transmissions de données sur divers réseaux, parmi lesquels des réseaux téléphoniques publics commutés et des réseaux numérisés, dont T1, E1 et RNIS. Les différents modes de réalisation permettent également d'effectuer une simulation de signaux (370) de divers réseaux de sorte que le réseau couplé actuel est transparent pour un terminal de données transférant des informations via le dispositif de transmission de données sur le réseau.
