Abstract

PURPOSE:To connect the sound frequency telegram device and the data transmission interface device without intervention of software, by connecting them directly through no time division switch. CONSTITUTION:The analogue signal of sound frequency telegram device VFT11 is encoded through CODEC12. This signal is sent to switching circuit SEL9. In switching circuit SEL9, data transmitted from time division switch TDSW10 is sent to data transmmission interface device DTI8 normally as it is; and only when transmission timing TVFTt of the channel assigned for VGT comes, the output of VFT11 is transmitted. In the receiving operation, only when receiving timing TVFTr of the channel for VFT comes, the input is led into CEDEC12 and is transmitted to VFT11. As a result, the channel is assigned to the telegram device to connect it to a specific station independently of software control.
