Wide area network (WAN)-arrangement
First Claim
1. A communication system between LANs comprising:
- LAN interface means for providing a plurality of data packets containing information from a source LAN, each of said data packets having an address field with an address;
a communication network that provides a communication path to a destination LAN; and
network interface means for communicating each of said data packets to one of a plurality of variable bandwidth channels between said LAN interface means and said communication network, based on said address obtained from each of said packets received from said LAN interface means.

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.

23. A communication system between LANs comprising:
-
a router that provides a plurality of frame relay packets containing information from a source LAN, each of said packets having an address field with an address; a telephone network that provides a communication path to a destination LAN; and network interface means for communicating each of said data packets to one of a plurality of variable bandwidth channels between said router and said telephone network, based on said address obtained from each of said packets received from said router, said variable bandwidth channel comprising a plurality of fixed bandwidth channels, and said network interface means comprising an inverse multiplexer and map means for associating said address with a plurality of phone numbers.
