A packet switch arrangement in which a first plurality of user devices is connected to a packet network by a first interface unit and a second plurality of user devices is connected to the packet network by a second interface unit. A virtual circuit is established between the interface units and control information is exchanged over the virtual circuit. The control information defines virtual channels on the virtual circuit and ones of the first and second pluralities of user devices which are to be sources and destinations for data in the defined virtual channels. Data from user devices is packetized and transmitted in the virtual channels by the interface units in accordance with the exchanged control information. Further, packets received in virtual channels on the virtual circuit are distributed to user devices by the interface units in accordance with exchanged control information.
