Premium Broadband

Carriers are confronted with frequent complaints, high churn rate, and low average revenue per user (ARPU) in the existing FTTH market. Therefore, they must pay more attention to user experience. However, they are also confronted with significant challenges against experience O&M.
Of the complaints about slow Internet access, 70% cannot be quickly demarcated. Traditionally, to locate these faults, field visits and network O&M analysis are required. Field engineers locate the faults by capturing packets, restarting ONTs, and resetting devices only when the faults reoccur. This is inefficient and may cause repeated complaints and frequent field visits.
PON faults account for 25 to 40% of all faults reported by home broadband subscribers. Interruption faults are demarcated based on alarms and accurate information provided by the RMS. The faults are difficult to demarcated because the status of ODN devices cannot be obtained.
Long optical fibers, multiple levels of optical splitting, and dirty and loose optical fiber connectors may easily lead to weak optical signals. As a result, video services may freeze, Internet access slows down, and network access may be intermittent, causing low user satisfaction and numerous complaints. Carriers need to proactively identify and rectify weak optical signals to reduce network problems.

Use Cases

Home Broadband Network Visualization and Playback

After receiving a complaint, the call center or NOC remotely demarcates and locates the fault and accurately dispatches work orders (WOs) to avoid unnecessary field visits. NCE (Access Domain) dynamically restores the service topology, and provides 24/7 playback of KPIs to automatically identify abnormal indicators.

Automatic Identification of PON Faults

PON faults account for 25% to 40% of all faults. Due to long and complex optical lines, engineers need to troubleshoot the faults on site, which is inefficient. This decreases user satisfaction. NCE (Access Domain) uses the OLT to collect data and extract characteristics of ONTs, identifies fault types based on multi-KPI correlation analysis, and restores the ODN topology. With these features, NCE (Access Domain) accurately identifies the causes of faults on the feeder, distribution, and drop fibers. NCE (Access Domain) also supports automatic creation of WOs, improving efficiency of troubleshooting PON faults.

ODN Weak Optical Signal Analysis and Proactive Rectification in Batches

Huawei iMaster NCE (Access Domain) supports visualization of E2E network topology, provides 24/7 playback of KPIs, and remotely locates and demarcates faults, improving the troubleshooting efficiency. It enables a digital world to be built on the cloud based on the collected and converged network data.
