Abstract

PURPOSE:To constitute a non-blocking system and to improve operability by forming a stage by the use of one type of switch frame, further, forming an inter-stage by the use of a link bundle and forming these stage in a multi-step way. CONSTITUTION:The respective stages are composed of the switch frame of one type (size 45X89 and 89X45) and the respective inter-stages are formed based on the fundamental link of two types (size 45 and 89). For a main body system, the non-blocking system is constituted by these three stages-constitution. Thus, the type of system constituting elements is reduced, the constitution is simplified and manufacture comes to be easy. As the result, mass-productivity and the operability of a system using can be improved.
