Embodiment 1

[0055] refer to figure 1 , this embodiment provides a system for remotely logging in to an optical network unit, the system for remotely logging in to an optical network unit includes: an optical line terminal (OLT) and an optical network unit (ONU), and the optical line terminal includes a command line unit and a second A management control unit, the optical network unit includes a second management control unit, a proxy unit and a local service unit.

[0056] Wherein, the command line unit can receive commands input from the outside, and can also present execution results corresponding to the names.

[0057] Wherein, the first management control unit and the second management control unit are specifically management control interfaces, responsible for transmitting commands and command execution results between the OLT and the ONU. When the system is a GPON system, both the first management control unit and the second management control unit are management control units base...

Embodiment 2

[0076]The aforementioned embodiment mainly describes the structure of the passive optical network system, and the method for implementing the remote login to the optical network unit in the passive optical network system of the above-mentioned embodiment is described below.

[0077] refer to figure 2 , the method for remotely logging into an optical network unit includes the following steps:

[0078] Step 10: the command line unit receives the Telnet command, and the first management control unit encapsulates the Telnet command and transmits it to the second management control unit.

[0079] Wherein, the command line unit provides externally the command interaction in the whole process from Telnet to the ONU, receives the Telnet command input by the user, and outputs the execution result of the Telnet command on the ONU side.

[0080] When the first management control unit is a management control unit based on the OMCI protocol, the first management control unit uses private...

Embodiment 3

[0096] When the system is a GPON system, and both the first management control unit and the second management control unit are management control units based on the OMCI protocol, wherein, in image 3 In the illustration, the first management control unit is the first OMCI unit, and the second management control unit is the second OMCI unit. Such as image 3 As shown, the method for remotely logging in to the ONU includes the following steps:

[0097] Step 20: Send Telnet command.

[0098] In this embodiment, the command line unit sends the received Telnet command to the first OMCI unit.

[0099] Step 21: Encapsulate the Telnet command into a private ME attribute, and transmit the encapsulated Telnet command.

[0100] In this embodiment, the first OMCI unit encapsulates the Telnet command into a private ME attribute, and transmits the encapsulated Telnet command to the second OMCI unit. In actual application scenarios, you can call the Set method and point the attribute to...

Abstract

The invention discloses a system and method for remotely logging in an optical network unit. The system comprises an optical line terminal and the optical network unit, wherein the optical line terminal comprises a command line unit and a first management control unit, and the optical network unit comprises a second management control unit, a proxy unit and a local service unit. In the method, aTelnet command is input into the command line unit on an OLT side; the Telnet command is transmitted to the ONU through the first management control unit located at the OLT and the second management control unit located at the ONU; the proxy unit on the ONU side converts the received command into a Telnet protocol, and performs Telnet protocol interaction with the local service unit of a local loopback address to realize remote login of the ONU; andhe ONU feeds back an execution result to the command line unit on the OLT side through the proxy unit, the first management control unit and the second management control unit, so that the Telnet interaction between the OLT and the ONU is realized.

Description

technical field [0001] The invention belongs to the field of optical communication, and more particularly relates to a system and method for remotely logging in to an optical network unit. Background technique [0002] In the passive optical network PON (Passive Optical Network, abbreviated as PON) system, when the optical network unit ONU (Optical Network Unit, abbreviated as ONU) in the existing network fails, sometimes it is necessary to log in to the ONU remotely. The main practice of remote Telnet to ONU at present is to carry out by creating the IP (Internet Protocol, abbreviated as IP) address of service channel and three-layer interface between optical line terminal OLT (Optical Line Terminal, abbreviated as OLT) and ONU. Among them, the IP address of the layer-3 interface is issued by the OLT to the ONU through the optical network unit management control interface OMCI (ONUManagement and Control Interface, abbreviated as OMCI) or OAM (Operation Administration and Ma...
