- An optical transmission channel is provided between the Line Terminal, the optical line unit, and the ONU (Optical Network Unit).
- the deployment and management of the traditional 0DN network fiber depends on the manual mode. It is necessary to manually input the fiber connection to the back-end database, and the error rate is high. It is difficult to quickly locate the fault point during maintenance, which is inefficient. With the construction of FTTx (Fiber-to-the X, fiber access) entering the era of scale deployment, the demand for massive fiber deployment and efficient management in FTTx networks has caused operators to face high deployment costs and huge operational and maintenance pressures. .
- the existing intelligent 0DN management system maintenance management system is mainly divided into three parts: local maintenance terminal, local maintenance center and remote maintenance center, as shown in Figure 1.

- the remote maintenance center and the local maintenance terminal must first apply for permission to the local maintenance center. If the permission is successful, the operation command can be issued.
- the remote maintenance center and the local maintenance terminal need to have exclusive control over the intelligent 0DN management system, perform the lock configuration right operation, and after the lock configuration right operation is completed, the other maintenance management cannot perform any operation on the 0DN device. You must wait for the remote maintenance center and the local maintenance terminal to unlock the control of the intelligent 0DN management system before issuing the operation command.
- the remote control center and the local maintenance terminal lock the control time of the intelligent 0DN management system for more than the set time limit, the automatic unlocking is automatically performed.

智能 0DN管理系统由主控管理单元和子框配线控制板组成。 主控管理 单元最多配置一个, 可以通过网络接口与远程维护中心通信, 也可以直接 通过 USB接口连接现场操作的本地维护中心, 或者由本地维护终端迸行操 作。 子框配线控制板用于对配线接口板进行控制管理, 主控管理单元通过 RJ45接口管理多个子框, 每个子框可遥过子框配线控制板管理多个配线接 口板。
本发明提供的智能 0DN管理系统的维护方法, 包括以下步骤:
( 1 ) 对同一个操作任务进行互斥保护。
对每个可执行的操作任务用操作权限进行保护, 任何一个维护管理终 端在执行操作任务之前, 都要先获取对这个操作任务的操作权限, 并在操 作任务执行完毕之后, 释放相应的操作权限, 所述维护管理终端包括本地 维护中心、 远程维护中心和本地维护终端。
2 ) 对不同的维护管理终端进行互斥保护。
因为本地维护中心享有较高的优先级, 0DN设备启动之后首先检测是否 已连接本地维护中心, 如果已连接, 则由本地维护中心获得对系统的控制 权。 这种状态下远程维护中心和本地维护终端要操作必须先要向本地维护 中心申请权限, 申请权限成功, 才能下发操作指令, 远程维护中心和本地 维护终端获得操作权限之后, 本地维护终端也可以对 0DN设备迸行操作。 远程维护中心和本地维护终端如果需要独享对智能 0DN管理系统的控制权, 不允许其它维护管理终端操作系统, 可以执行锁定配置权操作, 锁定配置 权之后, 其他的维护管理终端不能对 0DN设备执行任何操作, 必须等待配 置权解锁之后才能下发操作指令。 如果远程维护中心和本地维护终端锁定 配置权限的时间过长, 超过设定的最大等待时间, 则自动解锁。
本地维护中心可以抢占操作权, 并且将配置数据恢复到远程维护中心 和本地维护终端获得配置权限之前的配置。

步骤 S260 , 操作完成之后释放对操作对象的锁定, 使其他维护管理终 端可以获取到对该操作对象的操作权限, 结束;
歩骤 S270、 等待操作对象被释放;
