Migration strategy towards Q3 interfaces of switching systems : a look at France Telecom switches

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.
