CONTROL INFORMATION COMMUNICATION ARRANGEMENT FOR A DISTRIBUTED CONTROL SWITCHING SYSTEM Abstract A switching system including a number of switching modules each having a plurality of access ports. Incoming and outgoing packet channels are extended between each switching module and an inter-module packet switch. Each of the switching modules includes both a packet switching unit and a circuit switching unit for switching information to and from the access ports. Each switching module further includes a control unit that controls the switching units and that generates inter-module control packets, and a communication interface that transmits inter-module control packets generated by the control unit on theincoming packet channel to the inter-module packet switch. The communication interface also transmits inter-module control packets received on the outgoing packet channel from the inter-module packet switch to the control unit. The inter-module packet switch concurrently packet switches inter-module control packets received on a number of the incoming packet channels, via multiple independent paths to a number of the outgoing packet channels.
