-24,上行：+4- -1），若光功率不在正常范围内，而且注册正常的话，可判断为光模块问题，一般而言，光模块坏的话，ONU注册是不会正常。 本地WEB页面用户侧信息查询入口：【WEB页面】-【状态】-【用户测信息】界面示例：查看界面中LAN口信息，通过接收和发送信息流量来进行简单判断，流量正常且无错误帧，则端口正常，否则端口异常，用户侧故障。1.2 上网慢故障诊断1.2.1 本地查询ONU LAN口信息入口：【WEB页面】-【状态】-【用户测信息】界面示例：查看接收发送信息，判断是否用户线或终端问题。1.2.2 本地查询ONU 链路质量入口：【WEB页面】-【状态】-【网络测信息】界面示例：根据告警信息、光模块信息对比正常收发光功率，判断是否链路问题，也可通过专门的光功率计进行测量。1.2.3 OLT上查询ONU总带宽入口：【C220】-【EPON配置】-【ONU管理】-【ONU基本信息管理】-【SLA配置】界面示例：检查上下行速率配置是否按规划配置，是否带宽配置过小。同时用光功率计测试一下PON口的光功率值，看是否满足要求（接收光功率：-27 - -6，发送光功率：+2-+7），判断光模块性能。1.2.4 OLT上查询上联板口负载入口：【C220】-【系统配置】-【系统负载查询】-【选择单板】界面示例：查看CPU负载率（最好不超过10%）和内存使用率（最好不超过60%）1.3 常掉线故障诊断1.3.1 本地查询ONU LAN口信息（同3.2.1）查看是否有丢包或流量异常，检查用户终端或用户线问题。1.3.2 查询网管告警信息（同3.1.3）查询故障ONU是否有离线或掉电告警，是否有OLT上联口链路告警。1.4 摘机无音故障诊断1.4.1 查询ONU状态（同3.1.1）1.4.2 查询OLT PON板状态(同3.1.2)1.4.3 查询ONU告警(同3.1.3)1.4.4 本地查询ONU信息(同3.1.4)1.4.5 本地查询MG信息点击“网络”“宽带设置”“连接名称选VOIP连接的名称”查看MG的配置信息，配置信息需正确。点击“应用”“宽带电话设置” 查询SIP注册参数信息，包括服务器IP/端口，用户号码和密码等（以上示图中的选项需要正确填写）1.4.6 本地查询MG接口状态“状态”“网络侧信息”页面查看MG接口状态查看窄带服务对应的状态正常为连接，IP地址列正常有获得自己的语音IP地址，有异常PING上层SS/网关，通检查MG和上层数据的配置，无异常检查POTS口信息。1.4.7 本地查询POTS口状态“状态”“宽带语音信息”页面查看VOIP(SIP)注册信息查看语音业务注册状态，已注册正常，若为未注册，则PING SS/MG网关，通检查MG的配置和上层设备的参数配置是否一致或匹配。1.4.8 本地PING MG网关/SIP注册服务器在“诊断”“网络诊断”PING 工具检查链路的连通性。1.5 打进打不出故障诊断1.5.1 本地查询MG信息（同3.4.5）1.5.2 本地查询MG接口状态(同3.4.6)1.5.3 本地查询POTS口状态(同3.4.7)1.5.4 在SS上进行信令跟踪检查用户号码的呼叫权限，没限制，则SS进行信令跟踪，查看信令是否有问题，若信令无问题，检查外线正常，则在ONU上进行抓包。1.5.5 在ONU上抓包端口镜像页面/engdebugeth.cmd勾选，点击应用，LAN1口抓包，对抓包进行分析，判断是MG问题还是与上层设备对接问题，不需要抓包时，需要关闭端口镜像功能，以免影响用户正常使用。2 华为FTTH故障运维1、 故障处理流程：1、FTTH-LAN-不能上网2、 FTTH-LAN-上网慢3、 FTTH-LAN-常掉线4、 FTTH-VOIP-摘机无音流程5、 FTTH-VOIP-打进打不出6、 FTTH-VOIP-打出打不进7、FTTH- VOIP-单通/双不通8、FTTH- VOIP-杂音9、FTTH- VOIP-回音10、FTTH-VOIP-时断时续11、FTTH-VOIP-传真问题2.1 常用诊断手段2.1.1 查询设备版本【网管】【终端】2.1.2 ODN故障排查 ONT掉电网管排障【查询告警】检查是否存在“ONT掉电(DGi)”告警，监视告警频度是否过高，排除电源故障。【检查ONT上次掉线原因是否为Dying Gasp】如果掉线原因为Dying-Gasp则说明ONT掉电。命令行排障【检查ONT上次掉线原因及掉线时间】XY-YEW-OLT3(config-if-epon-0/1)#display ont info 0 11 -
