Embodiment 1

[0055] see 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), the optical line terminal includes a command line unit and a first A management control unit, the optical network unit includes a second management control unit, an agent unit and a local service unit.

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

[0057] The first management control unit and the second management control unit are specifically management control interfaces, which are 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 based on the OM...

Embodiment 2

[0076]The foregoing embodiment mainly describes the structure of the passive optical network system, and the following describes the method for remotely logging in to the optical network unit in the passive optical network system of the above-mentioned embodiment.

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

[0078] Step 10: The command line unit receives a 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 externally provides command interaction in the whole process from Telnet to the ONU, receives Telnet commands input by users, and outputs the execution results of the Telnet commands 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 adopts the private ME attribute to c...

Embodiment 3

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

[0097] Step 20: Send Telnet commands.

[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 the private ME attribute, and transmit the encapsulated Telnet command.

[0100] In this embodiment, the first OMCI unit encapsulates the Telnet command into the private ME attribute, and transmits the encapsulated Telnet command to the second OMCI unit. In practical application scenarios, you can call the Set method and point the property to Me-15...

Abstract

The invention discloses a system and method for remotely logging in to an optical network unit. The system includes an optical line terminal and an optical network unit. The optical line terminal includes a command line unit and a first management control unit. The optical network unit includes a second management control unit, Agent unit and local service unit. In the present invention, the Telnet command is input in the command line unit of the OLT side, and the Telnet command is passed to the ONU by the first management control unit of the OLT and the second management control unit of the ONU, and the agent unit of the ONU side will receive the The command is converted into the Telnet protocol, and the Telnet protocol interaction is performed with the local service unit of the local loopback address to realize remote login to the ONU. The ONU then feeds back the execution result to the command line unit on the OLT side through the agent unit, the first management control unit and the second management control unit, realizing the Telnet interaction between the OLT and the ONU.

Description

technical field [0001] The invention belongs to the field of optical communication, and more particularly, relates to a system and method for logging in to an optical network unit remotely. Background technique [0002] In a 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, it is sometimes necessary to log in to the ONU remotely. At present, the main method of remote Telnet to ONU is to create a service channel and an IP (Internet Protocol, abbreviated as IP) address between the optical line terminal OLT (Optical LineTerminal, abbreviated as OLT) and the ONU. Among them, the IP address of the three-layer interface is issued by the OLT to the ONU through the optical network unit management and control interface OMCI (ONU Management and Control Interface, abbreviated as OMCI) or OAM (Operation Administration and Maintenance, abbreviated as...
