Abstract

PURPOSE:To constitute an independent link for voice and data easily and simultaneously by conventional switching technique, by storing a storage device with information informing the combination of a telephone set and a data terminal equipment. CONSTITUTION:A telephone set A and a data terminal Ta, and a telephone set B and a data terminal Tb are provided in couples, and pieces of information on their relations and equipment positions are stored in a storage device M. When a subscriber A sends a call signal to a subscriber B, a central processor CC sends a ringing tone RBT to the subscriber A and a call signal RG to the subscriber B by the known method and then connects the both together through an intraoffice trunk IOT. At the same time, the processor CC reads the equipment positions of the data terminals Ta and Tb coupling with the telephone sets A and B out of the storage device MM and sets the connection between the data terminals similarly to the connection between the telephone sets.
