## Abstract

A system for NETCONF based alarm management for a PON network.

## Claims

### Claim 1

An alarm management system for a passive optical network comprising:
(a) said alarm management system receiving (1) a first plurality of Network Configuration Protocol (NETCONF) alarm Yet Another Next Generation (YANG) model messages having an organization that are compliant with RFC8632 from one or more optical network terminals and/or one or more optical line terminals and (2) receiving a second plurality of Network Configuration Protocol (NETCONF) defect YANG model messages having an organization that are not complaint with RFC 8632 from one or more optical network terminals and/or one or more optical line terminals;
(b) said alarm management system forwarding said first plurality of messages and said second plurality of messages to a message bus;
(c) said alarm management system receiving said first plurality of messages and said second plurality of messages from said message bus and translating each of said defect YANG model messages not complaint with RFC 8632 to respective said alarm YANG model messages complaint with RFC 8632;
(d) said alarm management system forwarding said translated said defect YANG model messages not complaint with RFC 8632 to said respective said alarm YANG model messages complaint with RFC 8632 to said message bus;
(e) said alarm management system receiving said forwarded said translated said defect YANG model messages from said message bus and maintaining said translated said defect YANG model messages in a data store;
(f) said alarm management system maintaining said first plurality of messages in said data store;
(g) said alarm management system provides data from said data store upon request from a computer system outside said alarm management system.

### Claim 2 (depends on 1)

The alarm management system of claim 1 where said defect YANG messages are compliant with TR-355.

### Claim 3 (depends on 1)

The alarm management system of claim 1 wherein said NETCONF is included on top of a remote procedure call (RPC) layer.

### Claim 4 (depends on 3)

The alarm management system of claim 3 wherein said NETCONF uses an extensible markup language and/or JavaScript object notation based data encoding.

### Claim 5 (depends on 1)

The alarm management system of claim 1 wherein said at least one of said optical line terminals includes a virtual optical line terminal.

### Claim 6 (depends on 1)

The alarm management system of claim 1 wherein said at least one of said optical network terminals includes a virtual optical network terminal.

### Claim 7 (depends on 1)

The alarm management system of claim 1 wherein said messaging bus is a KAFKA bus.

### Claim 8 (depends on 1)

The alarm management system of claim 1 wherein data in said data store is modified.
