Abstract
Abstract A WAN is formed using Frame Relay Protocol and a telephone network interface unit. An originating LAN sends a message to a router which communicates with a telephone network interface unit using Frame Relay Protocol. The telephone network interface unit determines the destination of a packet received from the router by interpreting the Frame Relay Protocol, and it associates a phone number with that destination. The interface unit uses the phone number to establish at least one DSO connection over a digital telephone network to a destination network interface. A destination network interface unit receives the packet from the digital telephone network and provides the packet to a router which interfaces to the destination LAN. The network interface units add or drop additional DSO channels as required by the traffic load and thereby provide variable bandwidth.
