Abstract
A method for making IEEE 1588 master clock configuration for an ONU in a PON includes creating a PTP port on a UNI of the ONU, and generating a corresponding PTP port ME for the PTP port to indicate that the UNI is operating in a master clock mode; generating a 1588 master clock configuration data ME based on PTP port MEs of all PTP ports in the ONU, to store profiles of all PTP ports used as master clock devices; and generating a clock data set ME according to the 1588 master clock configure data ME, to indicate clock source information of all PTP ports used as master clock devices.

A method for making IEEE 1588 master clock configuration for an optical network unit (ONU) in a passive optical network (PON), comprising:
- creating a precision time protocol (PTP) port on a user network interface (UNI) of the ONU, and generating a corresponding PTP port management entity (ME) for the PTP port to indicate that the UNI is operating in a master clock mode;
- generating a 1588 master clock configuration data ME based on PTP port MEs of all PTP ports in the ONU, to store profiles of all PTP ports used as master clock devices;
- and
- generating a clock data set ME according to the 1588 master clock configuration data ME, to indicate clock source information of all PTP ports used as master clock devices.
An apparatus for making IEEE 1588 master clock configuration for an optical network unit (ONU) in a passive optical network (PON) through optical network unit management and control interface (OMCI) messages, comprising:
- a precision time protocol (PTP) port management entity (ME) creating unit, configured to create a PTP port on a user network interface (UNI) of the ONU and to generate a corresponding PTP port ME for the PTP port to indicate that the UNI is operating in a master clock mode;
- a 1588 master clock configuration data ME generating unit, configured to generate a 1588 master clock configure data ME based on PTP port MEs of all PTP ports in the ONU, to store profiles of all PTP ports used as master clock devices;
- and
- a clock data set ME generating unit, configured to generate a clock data set ME according to the 1588 master clock configuration data ME, to indicate clock source information of all PTP ports used as master clock devices.
