PURPOSE: A method for integratedly managing ISDN-PRI(Integrated Services digital Network-Primary Rate Interface) protocol is provided to reduce a time required for trunk matching by converting a mode of a local station system according to a mode of a remote station system. CONSTITUTION: A local station system transmits an interface setup message to a remote station system in the case of a network mode(S51). It is confirmed whether the remote station responses to the interface setup message to judge a mode of the remote station(S52). In the case of a user mode, the local station system maintains matching with the remote station system and a service(S53). In the case of a network mode, the local station system drives a timer(S54). If the timer is terminated, the network mode of the local station system is converted into a user mode(S56). The local station system transmits an interface re-setup message to the remote station system(S57).
