。 It has a central processing unit, receives two types of independent digital information B1, B2, and a digital control signal D from the switching equipment, and transmits the information B1, B2 and control signal D received from the terminal side to the switching equipment. ,
When receiving a control signal from the central processing unit, it creates a communication path for transmitting and receiving information B1 and B2 between the data terminal equipment (or handset) and the exchange equipment,
On the terminal side, one transmission path and one reception path are provided for each of the information B1 and B2, and a line interface unit is provided to create a communication path for transmitting and receiving the control signal D between the switching equipment and the central processing unit. Digital signal from the line interface section (information B1
or B2) into an analog signal (voice), convert the analog signal (voice) from the handset into a digital signal (information B1 or B2), and CODEC
Two handset connectors are provided to connect the handset, two handset connectors are provided to connect the handset, and the data terminal equipment and the control signal are sent and received.The central processing unit and the control signal are sent and received.The line interface unit and the data terminal Two digital interface sections are provided between the equipment to create a data communication path, two data terminal connectors are provided to connect the data terminal equipment, and an audio system consisting of the aforementioned one CODEC and one handset connector is provided. Two data system communication paths are provided, each consisting of one digital interface unit and one data terminal connector, and one voice system communication path and one data system communication path are provided. Similarly, one audio communication channel and one data communication channel are assigned exclusively to information B2, between the line interface section and the CODEC, and between the line interface section and the digital interface section. When a control signal is received from the central processing unit, the line interface unit simultaneously converts one transmission path and one reception path corresponding to information B1 on the terminal side into an audio communication path (or a data communication path). One switching device is provided for switching, and one switching device similar to B1 is provided for information B2 on the line interface terminal side, and two independent information B1 are provided.
, B2 are provided with several communication channel selection keys for selecting one of the audio communication channels and one data communication channel assigned to each of them and sending the selection information to the central processing unit. A display device is provided that displays the type of communication path selected in response to pressing one or several communication path selection keys for both information B1 and B2, and when a communication path selection key is pressed, B1 or B2 is selected as an audio communication channel (or a data communication channel), and the display device always displays the type of the selected communication channel (audio or data) for both B1 and B2. Voice/data communication path control device.
