Abstract

PURPOSE:To prevent erroneous connection by comparing the other-party number code, which is held in the unit itself, and the connection other-party number code, which is tranmitted from the digital communication network, with each other and by disconnecting line connection in case of their disagreement. CONSTITUTION:When one channel CHi is selected by the key switch of keyboard 1, it is detected by microcomputer 8, and transmission program data is read out from ROM7a and is stored in RAM8b. The other-party number code addressed by CHi is read out from RAM7b on a basis of this program data and is stored in the internal RAM of CPU8a and is tranmitted to the line from the upper digit. When the connection other-party number code comes from the digital communication network, this code is compared with the code stored in the RAM; and if they agree with each other, the control is transferred to the transmission routine. In case that they do not agree with each other, line connection is disconnected.
