31 Digital Switching Systems — Space Switching

Types and characteristics of space switching network

The space switching network operates with inputs and outputs organized in N time slots. Information from input time slots is routed from every input mux to a specific output mux without modification of the time position. Gates in crossbars are opened only for the duration of the corresponding time slot.

• Time slots: The network works at inputs and outputs with N time slots.
• Routing: Information of input time slots is routed from each input mux to a specific output mux without changing the time position.
• Crossbar gates: Gates in crossbars are opened only for the period of the time slot.
• Eight-bit words: Eight-bit words are carried through the space
