Abstract

The invention discloses a method for remotely configuring the precise time synchronization protocol (PTP) service of an optical network unit (ONU), which includes: creating a PTP management entity after the ONU is initialized; The set PTP management entity attribute; the ONU parses the PTP management entity attribute issued by the OLT, and performs corresponding PTP service setting according to the PTP management entity attribute. The invention also discloses an ONU, an OLT and a system corresponding to the method at the same time. After the OMCI channel is established, the ONU clock configuration can be completed on the OLT side, and the remote configuration of the PTP service through the OMCI is realized.

Description

technical field [0001] The present invention relates to the technical field of gigabit passive optical network (Gigabit Passive Optical Network, GPON), in particular to a remote configuration optical network unit (Optical Network Unit, ONU) precision time synchronization protocol (Precision Time Protocol, referred to as PTP or 1588) Methods, apparatus and systems for business. Background technique [0002] IEEE 1588v2 is a precision time synchronization protocol for network measurement and control systems, that is, PTP or 1588, which can achieve frequency and phase synchronization. PTP adopts the master / slave synchronization method, that is, the master and slave devices complete the synchronization function based on the sending and receiving time stamps of network data packets. GPON can complete the clock and time synchronization in the following way. The optical line terminal (Optical Line Terminal, OLT) connects to the time source to obtain time information, and then tran...
