Abstract

PURPOSE:To realize a data exchange system which enables the combination of the circuit exchange and the packet exchange and contains a large amount of the sharing areas with a high economical property. CONSTITUTION:In the connection system if the circuit exchange, the signals transmitted by the terminal calling and via multiplied highway 23 are received at signal transmitter/receiver 27 for the calling detection, and the detection information is sent to common processor 31 via microprocessor 28 to deliver the dial enable signals through the analysis at processor 31. The answer signal sent from the incoming terminal is sent to processor 31 through transmitter/receiver 27 and microprocessor 28. Based on this result, the connection completes. As for the packet exchange system, the signals are received at 27 in case the signals on the connection procedures all feature the packet system, thus carrying out the flag detection, the ''O'' contorl and others. The frame level and the packet level are processed at 27 and 31 each. And the prescribed connection control is given.
