Abstract
A permanent virtual connection (PVC) is automatically set up over an Ethernet local area network (LAN) link between a work station device having a digital telephone and a Communications Switching Module (CSM) when the device is first connected to the LAN. The PVC is established by exchange of information in standard Ethernet packets between the device and the CSM. Automatic reservation of a full duplex PVC for digital telephone signaling and control information enables set up and break down of voice channels within the same PVC by exchange of signaling information in standard Ethernet packets.
