Abstract

A method and system state-of-the-art private VoIP network for delivery of high quality, lower cost voice and data services to business customers across the United States. The unique implementation of the latest networking and Internet technologies over a privately managed network produces Quality of Service that rivals traditional circuit-switched calls and allows customers to capitalize on the convergence of traditional circuit-switched voice networks with packet-based networks. Proprietary account management, call detail recording, and accounting software complements the equipment and satisfies the administrative needs of business customers. Customers receive the added security and flexibility of “virtual private networks” through the implementation of IP technology, advanced switching equipment, and Asynchronous Transfer Mode (“ATM”) operation of the fiber optic backbone.

Claims

1. A method for transporting voice, data, and video telephony comprising:

receiving a digital data stream within a first edge gateway;

converting said digital data stream into at least one IP datagram;

transmitting said at least one IP datagram from said first edge gateway to a WAN switch;

encapsulating said at least one IP datagram into at least one ATM cell;

transmitting said at least one ATM cell from said WAN switch to a remote WAN switch over a pre-established virtual circuit over a WAN backbone;

decapsulating said at least one IP datagram from said at least one ATM cell;

transmitting said at least one decapsulated IP datagram from said remote-WAN switch to a second edge gateway;

establishing a connecting circuit from said second edge gateway to an external communications network;

decoding and decompressing said at least one decapsulated IP datagram; and

transmitting said at least one decoded and decompressed decapsulated IP datagram from said second edge gateway over said connecting circuit.

2. A system for transporting voice, data, and video telephony comprising:

a first edge gateway for converting a digital data stream into at least one IP datagram;

a first WAN switch for encapsulating said at least one IP datagram into at least one ATM cell;

a second WAN switch for decapsulating said at least one IP datagram from said at least one ATM cell;

a WAN backbone for connecting said first and second WAN switches;

a virtual circuit pre-established between said first and second WAN switches over said WAN backbone for transporting said at least one ATM cell from said first WAN switch to said second WAN switch; and

a second edge gateway for decoding and decompressing said at least one decapsulated IP datagram, for establishing a connecting circuit to an external communications network, and for transmitting said decoded and decompressed decapsulated IP datagram over said connecting circuit.
