NETWORK CONSTITUTION

摘要

PURPOSE:To constitute an economical and flexible network corresponding to the network capacity by providing a network module comprising a time switch and a spatial switch as one unit. CONSTITUTION:A primary time switch group 50, a secondary time switch group 60 and a split spatial switch 20 are formed on one module. The primary time switch group 50 and the split spatial switch 20 and the secondary time switch group 60 and the split spatial switch 20 are connected directly with each other respectively. The incoming line multiple connection of the split spatial switches 20-23 constitute one network module with the primary time switches 20-23. Thus, the number of interfaces for connecting modules and number of cables for connecting modules are halved.
