A method, in an electronic switching system comprising a main processor and line processors which can adapt K number of signaling types, N and K being positive integers, respectively, wherein the system is connected to another electronic switching system at trunk ports through trunk lines and the main processor includes a database for the line processors, route data, prefix data and state of the trunks including the trunk lines and the trunk ports, comprises the steps of: identifying a signaling type of a line processor; informing the identified signaling type to an operator; checking whether the trunk port connected to the line processor adapts the identified signaling type or not if the operator decides to change the identified signaling type; deleting data of the trunk in the main processor's database and assigning a new signaling type to the line processor if said trunk port adapts the identified signaling type, wherein the new signaling type is a same signaling type as used in said another electronic switching system connected thereto; assigning the new signaling type to the line processor if said trunk port does not adapt the identified signaling type; changing data of the line processor in the main processor's database into data concerning said new signaling type; and generating route data, making new data of the trunk and generating prefix data in the main processor's database.
