Abstract

A method for automatically managing an address of a remote access device (RAD) is disclosed. The method comprises defining the RAD at a service provider, the RAD being located physically remote from the service provider, and assigning a network address to the RAD. The service provider sends a query from a service provider element (SPE) to the RAD requesting the network address.

Claims

1. A method for automatically managing an address of a remote access device (RAD), comprising:

defining the RAD at a service provider, the RAD being located physically remote from the service provider;

assigning a network address to the RAD;

receiving at the service provider, a communication from the RAD; and

sending a query from the service provider to the RAD requesting the network address.

2. The method of claim 1, further comprising:

detecting, at the service provider, a communications frame within the communication from the RAD; and

acquiring a device address of the RAD from the communications frame, the device address being used to send the query.

3. The method of claim 1, further comprising:

detecting, at the service provider, a communications frame within the communication from the RAD; and

sending the query from the service provider to the RAD requesting the network address based on the communications frame.

4. The method of claim 1, further comprising assigning to the RAD first and second addresses associated with different protocol layers, the network address constituting the second address.

5. The method of claim 1, further comprising interconnecting the RAD and the service provider over an access network.

6. The method of claim 1, further comprising locating the RAD at a customer premise and locating the service provider at a service provider premise, the customer and service provider premises being interconnected by an access network.

7. The method of claim 1, further comprising providing a service provider element (SPE) at the service provider, the SPE sending the query from the service provider to the RAD requesting the network address.

8. The method of claim 1, further comprising interconnecting the RAD with a digital cross-connect switch (DCS) located at the service provider, the DCS initiating the query from the service provider to the RAD requesting the network address.

9. The method of claim 1, further comprising providing at the service provider an element management system (EMS), the EMS updating a RAD address table at the service provider based on the network address received from the RAD.

10. The method of claim 1, further comprising transmitting from the RAD to the service provider the network address assigned to the RAD upon receiving the query at the RAD.

11. The method of claim 1, further comprising, in response to the query, determining whether the network address of the RAD has changed, and updating a RAD address table at the service provider with the changed RAD network address when the RAD network address changes.

12. The method of claim 1, wherein said sending a query is automatically repeated at a predetermined interval.

13. The method of claim 1, further comprising:

determining whether a response to the query is received from the RAD; and

identifying a communications failure when no response is received in connection with the query.

14. A system for automatically managing an address of a remote access device (RAD), comprising:

a RAD located at a customer premise;

a service provider element (SPE), the SPE sending a query to the RAD requesting a network address of the RAD, the RAD having a unique network address assigned thereto;

a service provider located at a service provider premise, the service provider premise and the customer premise being physically remote from one another; and

an access network interconnecting the RAD and service provider.

15. The system of claim 14, wherein the SPE monitors communications over the access network from the RAD, the SPE sending the query to the RAD based upon information within the communications received from the RAD.

16. The system of claim 14, wherein the SPE receives a response to the query and sends an autonomous message to an element management system (EMS), the EMS updating a RAD address table with the network address of the RAD obtained from the autonomous message.

17. The system of claim 14, further comprising an element management system (EMS), the EMS sending a query to the SPE requesting the network address of the RAD, the SPE responding to the query from the EMS with a query response containing an autonomous message conveying the network address of the RAD.

18. The system of claim 14, wherein the RAD interconnects the access network and a customer network.

19. The system of claim 14, wherein the RAD is defined at an element management system (EMS) of the service provider by updating a RAD address table.

20. The system of claim 14, wherein the SPE sends an autonomous message to an element management system (EMS) via a data communications network (DCN).

21. The system of claim 14, wherein the RAD is an Ethernet access device.
