The time-division circuit-switching network and circuit-switching call control software are developed and implemented for a Hybrid data switching network.
The general switching methods such as circuit switching, message switching and packet switching, and their differences are briefly reviewed.
The overall structure of a Hybrid data switching network are described, which consists of three switching nodes, each having both circuit-switching and packet-switching parts.
The simple time-division switching network is designed to interconnect the time slots for oversampled user data samples with a synchronous address control in the input highway (MUX) and the output highway (DMUX).
The call control software is explained in detail, which includes the programs for call store and forward function and a direct call transfer to the PAD (Packet assembly and disassembly) for calls to a different switching nodes.
The experimental results of the implemented systems are discussed.
연구 실험용 Hybrid Data Switching Network의 Circuit Switching System에 대한 Switching network와 Control software가 설계 구성되었으며 이 system의 동작이 확인되었다. 일반적인 switching방식 즉 Circuit-switching, message switching, Packet switching과 이들에 대한 차이점들이 간단히 비교 설명되었다.
Hybrid Data Switching Network는 3개의 node와 각 node는 Circuit-switching과 packet-switching part로 나누어 지며 이에 대해서도 간략히 언급되었다.
간단한 Time division switching network가 변경 설계 되었으며 store and forward 기능과 PAD(packet assembly and disassembly)의 Call set-up에 대한 program을 포함한 Call Control software가 자세히 설명되었다. 마지막으로 설계 구성 된 system의 특성 및 call 처리용량에 대해서 대략적으로 검토되었다.
