Abstract
An apparatus and method that provides access between an enterprise network and at least one of a metropolitan area network and a wide area network. The apparatus includes an enterprise area network connection, a controller coupled to the enterprise area network connection, the controller providing Layer 1 and Layer 2 service, and a central office connection coupled to a central office, the central office providing Layer 3 and Layer 4 service. The controller transmits unmapped data across the central office connection to the central office and the central office maps the unmapped data onto a desired format.
Claims25
A first access device that provides access between an enterprise network and at least one of a metropolitan area network and a wide network, comprising:
- an enterprise area network connection providing connection to an enterprise area network;
- a controller coupled to the enterprise area network connection, the controller providing Layer 1 and layer 2 service;
- and
- a central office connection coupled to the controller and providing connection to a central office, the central office providing layer 3 and layer 4 service;
- wherein said controller comprises a first controller, said central office includes a second access device controller and said first controller transmits data through said central office connection to a second access device located at said central office;
- wherein said controller receives data from the enterprise area network connection and transmits multiple data formats across the central office connection to the central office using Layer 1 and layer 2 services.
An access device that provides access between an enterprise network and at least one of a metropolitan area network and a wide network comprising:
- an enterprise area network connection providing connection to an enterprise area network;
- a controller coupled to the enterprise area network connection, the controller providing Layer 1 and Layer 2 service;
- and
- a central office connection coupled to the controller and providing connection to a central office, the central office providing Layer 3 and Layer 4 service;
- wherein the controller further comprises:
- a timeslot allocation table including timeslot allocation information;
- and
- a transmitter coupled to the timeslot allocation table wherein the transmitter transmits data and updated timeslot allocation information in accordance with the timeslot allocation information.
A first access device for providing connection to a first local area networks and to a second local area network, comprising:
- a first local area network connection providing a connection to a first local area network;
- a second local area network connection providing a connection to a second local area network;
- and
- a first controller coupled to the first area network connection and coupled to the second local area network connection, the first controller providing Layer 1 service and Layer 2 service for direct connection of the first local area network to the second local area network without connection to a Layer 3 device;
- wherein the central office includes a second access device including a second controller and the first controller transmits data through the central office connection to the second controller of the second access device located at the central office;
- wherein said first controller receives data from the enterprise area network connection and transmits multiple data formats across the central office connection to the central office using Layer 1 and layer 2 services.
An access device for providing connection to a first local area network to a second local area network comprising:
- a first local area network connection providing a connection to a first local area netowrk;
- a second local area network connection providing a connection to a second local area network;
- and
- a controller coupled to the first local area network connection and coupled to the second local area network connection, the controller providing Layer 1 service and Layer 2 service for direct connection of the first local area network to the second local area network without connection to a Layer 3 device;
- wherein the controller further comprises:
- a timeslot allocation table including timeslot allocation information;
- and
- a transmitter coupled to the timeslot allocation table wherein the access device transmit data and updated timeslot allocation information in accordance with the timeslot allocation information.
