Abstract

La présente invention concerne un procédé de transformation d'un radiotéléphone analogique d'un mode de fonctionnement analogique en un mode de fonctionnement numérique et réciproquement par le fait que les vocodeurs d'émission (11) et de réception (12) peuvent être mis en servie ou non de façon manuelle ou automatique selon que le radiotéléphone opère respectivement dans un réseau analogique ou numérique. A cet effet, il est fait usage d'un modulateur d'émetteur unique (3) compatible à la fois avec des signaux numériques et les signaux analogiques et il est fait usage d'un démodulateur de réception unique (8) compatible à la fois avec des signaux numériques et les signaux analogiques.
