Abstract
A low-level reset message having a reset level provides a mechanism for an optical line terminal (OLT) to remotely reset a dysfunctional optical network unit (ONU). The reset message includes a reset level field which allows the OLT to instruct the ONU to perform a reset of some or all of its hardware and software components.
Claims20
An optical network unit (ONU) comprising:
- a memory configured to store a management information base (MIB), low-level software, and high-level software;
- a passive optical network (PON) interface configured to communicate using physical layer operations, administration, and maintenance (PLOAM) messages;
- and
- a processor coupled to the memory and the PON interface, with the processor configured to:
- execute the low-level software and high-level software;
- receive a PLOAM reset message comprising a reset level with the reset level comprising an indication of a component of the ONU to be reset;
- and
- reset the ONU according to the reset level.
A method for an optical network unit (ONU) to receive and process a physical layer operations, administration, and maintenance (PLOAM) reset message, the method comprising:
- receiving the PLOAM reset message comprising a reset level and with the reset level comprising an indication of a component of the ONU to be reset;
- and
- resetting the ONU according to the reset level.
An optical line terminal (OLT) comprising:
- a memory configured to store identity and state information about an optical network unit (ONU);
- a passive optical network (PON) interface configured to communicate with the ONU using physical layer operations, administration, and maintenance (PLOAM) messages;
- and
- a processor coupled to the memory and the PON interface, with the processor configured to:
- create a first PLOAM reset message comprising a first reset level, with the first reset level comprising an indication of a component of the ONU to be reset;
- and
- send the first PLOAM reset message to the ONU via the PON interface.
A method for an optical line terminal (OLT) to reset a remote optical network unit (ONU), the method comprising:
- creating a first physical layer operations, administration, and maintenance (PLOAM) reset message comprising a first reset level, with the first reset level comprising an indication of a component of the ONU to be reset;
- and
- sending the first PLOAM reset message to the ONU via a PLOAM channel.
