Abstract

Communication between an ONT ( 1 ) and a host device ( 2 ), which are connected to form a combined ONT-host unit, the communication being associated with an OMCI-configuration of the ONT-host unit. The communication uses a memory of the ONT, and the memory is accessible also to the host device, and comprises e.g. a lock registry. The ONT ( 1 ) could e.g. be mounted in an SFP, which is plugged into a suitable contact ( 3 ) in the host device ( 2 ).

First claim

The invention claimed is:

1. A method for an optical network termination, ONT, of transferring a message to a host device, wherein the ONT and the host device are connected to form a combined ONT-host unit, and the message is associated with an ONT Management and Control Interface, OMCI, -configuration of the ONT-host unit, the ONT being provided with a memory that is accessible also to the host device, the memory comprising a lock registry, the method comprising:
determining, by reading the lock registry, if the memory is available;
locking the memory to the host device, by writing in the lock registry, when determining that the memory is available;
writing a message in the memory, the message being associated with an OMCI-configuration of the ONT-host unit; and
indicating in the lock registry that a message from the ONT is available in the memory.

2. A method according to claim 1 , further comprising:
reading in the lock registry that a response to the message is available in the memory;
reading the response from the host device; and
indicating in the lock registry that the memory is not in operation.

3. The method according to claim 1 , wherein the message comprises at least one of an action identifier, a message identifier, and a message content.

4. The method according to claim 1 , wherein the ONT is mounted in a small form-factor pluggable, SFP, provided with an SFP interface, the method comprising the ONT using said SFP interface for transferring the message to the host device.

5. A method for an optical network termination, ONT, of receiving a message from a host device, wherein the ONT and the host device are connected to form a combined ONT-host unit, and the message is associated with an ONT Management and Control Interface, OMCI, -configuration of the ONT-host unit, the ONT being provided with a memory that is accessible also to the host device, the memory comprising a lock registry, the method comprising:
reading in the lock registry that a message from the host device is available in the memory; and
reading the message, the message being associated with an OMCI-configuration of the ONT-host unit.

6. The method according to claim 5 , further comprising:
performing an internal operation, based on the received message;
writing a result of the operation in the memory, as a response to the received message; and
indicating in the lock registry that a response is available in the memory.

7. The method according to claim 5 , wherein the message comprises at least one of an action identifier, a message identifier, and a message content.

8. The method according to claim 5 , wherein the ONT is mounted in a small form-factor pluggable, SFP, provided with an SFP interface, the method comprising the ONT receiving the message from the host device via said SFP interface.

9. A method for a host device of transferring a message to an optical network termination, ONT, wherein the ONT and the host device are connected to form a combined ONT-host unit, and the message is associated with an ONT Management and Control Interface, OMCI, -configuration of the ONT-host unit, a memory of the ONT being accessible also to the host device, the memory comprising a lock registry, the method comprising:
determining, by reading the lock registry, if the memory is available;
locking the memory to the ONT by writing in the lock registry, when determining that the memory is available;
writing a message in the memory, the message being associated with an OMCI-configuration of the ONT-host unit; and
indicating in the lock registry that a message from the host device is available in the memory.

10. The method according to claim 9 , wherein the message comprises at least one of an action identifier, a message identifier and a message content.

11. The method according to claim 9 , wherein the ONT is mounted in a small form-factor pluggable, SFP, provided with an SFP interface, the host device transferring the message to the ONT using said SFP interface.

12. A method for a host device of receiving a message from an optical network termination, ONT, wherein the ONT and the host device are connected to form a combined ONT-host unit, and the message is associated with an ONT Management and Control Interface, OMCI, -configuration of the ONT-host unit, a memory of the ONT being accessible to the host device, the memory comprising a lock registry, the method comprising:
reading in the lock registry that a message from the ONT is available in the memory; and
reading the message, the message being associated with an OMCI-configuration of the ONT-host unit.

13. The method according to claim 12 , further comprising:
performing an internal operation, based on the received message.

14. The method according to claim 13 , further comprising:
writing a response in the memory, the response indicating a a result of the operation;
indicating in the lock registry that a response is available in the memory.

15. The method according to claim 13 , further comprising:
indicating in the lock registry that the memory is not in operation.

16. The method according to claim 13 , wherein the message comprises at least one of an action identifier, a message identifier and a message content.

17. The method according to claim 13 , wherein the ONT is mounted in a small form-factor pluggable, SFP, provided with an SFP interface, the host device receiving the message from the ONT via said SFP interface.

18. An optical network termination, ONT, arranged to be connected to a host device to form a combined ONT-host unit, the ONT comprising:
a memory that is accessible to a host device connected to the ONT, the memory comprising a lock registry; and
a processing circuitry configured to transfer a message to the host unit, the message being associated with an ONT Management and Control Interface, OMCI, -configuration of the ONT-host unit, by:
determining, by reading the lock registry, if the memory is available;
locking the memory to the host device by writing in the lock registry, when determining that the memory is available;
writing a message in the memory, the message being associated with an OMCI-configuration of the ONT-host unit; and
indicating in the lock registry that a message from the ONT is available in the memory.

19. The ONT according to claim 18 , wherein the processing circuitry is further configured to transfer the message to the host unit by:
reading in the lock registry that a response to the message is available in the memory;
reading the response from the host device in the memory, and
indicating in the lock registry that the memory is not in operation.

20. The ONT according to claim 18 , wherein the message comprises at least one of an action identifier, a message identifier, and a message content.

21. The ONT according to claim 18 , wherein the ONT is mounted in an small form factor pluggable, SFP, and is provided with an SFP interface that is used for communicating with the host device.

22. The ONT according claim 18 , further comprising an OMCI management information base, MIB, for storing parameters associated with the OMCI-configuration.

23. The ONT according to claim 18 , wherein the memory is associated with a digital diagnostic monitoring-function of the ONT.

24. An optical network termination, ONT, arranged to be connected to a host device to form a combined ONT-host unit, the ONT comprising:
