Zusammenfassung: | PURPOSE:To attain a communication with the other side station without considering each kind of trunk signal system by the calling control module of a node system. CONSTITUTION:The node system is constituted of a calling control module 1, trunk signal interface module 2, and other module 3. Each module is equipped with the processing function of an M signal unified in the node system. And also, the trunk signal interface module 2 is equipped with a converting function which converts the M signal into each kind of trunk signal (A signal-Z signal). Then, the transfer and reception of information among the modules is operated by using the M signal, and the communication with the other side station is operated by using the trunk signals of the other side station by converting the M signal into the trunk signals of the other side station by the trunk signal interface module 2. |
