- 18 -REARRANGEABLE MULTICONNECTION SWITCHING NETWORKSEMPLOYING BOTH SPACE DIVISION ANDTIME DIVISION SWITCHINGAbstractA switching network including both space division and time divisionswitching stages where a permanent connection arrangement, interposed betweenthe network input channels and a larger number of internal, time division channelsat the input side of the space division stage, provides permanent rather thanswitched connections between each input channel and multiple internal channels.The pattern of permanent connections to multiple internal channels is designedsuch that the network is rearrangeable to avoid blocking to connect any idleoutput channel of the network to any busy or idle input channel.
