Abstract
Future telecommunication management network (TMN) will be based upon object-oriented modelling of interfaces. Nevertheless, in case of public switched telephone network, this process will be long and difficult. However, as current interfaces are not completely satisfactory, some evolution steps from today’s interfaces towards tomorrow’sTMN ones are planned. This paper presents the different steps chosen by France Telecom. At first, introduction of a new protocol as close as possible to the target Q3 is detailed. Unification of the different heterogeneous commands is then shown through creation of standard commands, last, integration toTMN through Q-adaptor is presented.
Résumé
Le réseau de gestion des télécommunications est basé sur une modélisation orientée objet des interfaces. Cette modélisation sera longue et difficile pour le réseau téléphonique public. Les interfaces actuelles n’étant pas complètement satisfaisantes, il est donc nécessaire de prévoir des étapes d’évolution en attendant les interfaces du RGT. Cet article présente les différentes étapes choisies par France Télécom. L’introduction d’un protocole intermédiaire le plus proche possible de Q3 est tout d’abord décrite. Les commandes standard qui permettent d’unifier les commandes actuelles sont ensuite présentées puis l’intégration éventuelle au RGT via un adaptateur.
