Abstract

PURPOSE:To enable the connection of intraoffice call, by providing the digital line connecting all the frames in the remote station in ring and providing the means inserting and picking up the audio signal every channel on the digital line with each frame. CONSTITUTION:The output of the digital line connected to the master station is selected 100-1-100-3, and the output of the connecting digital line for intra-office call connecting the line frame in the remote station in ring is selected 100-4-100-n. On the other hand, the input to the codec is selected 101-1-101-5. The digital line connection control circuit 102 receives the control information from the line frame control circuit and it is written in the memory 103, and the content is held in the buffer 104 with periodical readout to control the output selection circuit and the input selection circuit. With the remote station line frame thus constituted, since the intraoffice call is not in exchanger connection at the master station but connected in the remote station, the number of digital lines can be reduced. Further, when the control function is added to the remote station, exchange connection is enabled for the intraoffice call.
