Explain Non-Folded network

Non-Folded Network: In a switching network, every inlet/outlet connection may be utilized for inter exchange transmission. In this case, the .exchange does not assist local subscribers and is termed as a transit exchange. A switching network of this type is demonstrated in figure and is termed as a non-folded network. In non-folded network along with N inlets and N outlets, N simultaneous information transfers are possible. Therefore, for a non-folded network to be non-blocking, the network must support N simultaneous switching paths.
