ONMSi Solution Architecture: A Comprehensive Guide for Telecom Network Management
The need for high-performance, resilient, and easily managed telecom networks is growing alongside the advancements in 5G, IoT, and next-gen optical infrastructures. Unfortunately, traditional network management systems often struggle to provide the scalability, automation, and intelligent control that are crucial nowadays.
This is where ONMSi (Optical Network Management System – intelligent) comes in. It’s designed to centralize control, streamline operations, and integrate smoothly with IT systems, giving telecom operators a management framework ready for the future.
The diagram attached illustrates the ONMSi solution architecture, showcasing how various interfaces, controllers, and applications connect to the ONMSi server. In this blog post, we’re going to dive into the architecture, emphasizing its components, advantages, and its applications in telecom.
What is ONMSi?
ONMSi serves as a centralized optical network management solution that helps telecom operators with:
Fault Management – Quickly pinpointing and isolating network failures.
Configuration Management – Easing up the setup of devices and services.
Performance Monitoring – Keeping an eye on KPIs to ensure SLAs are met.
Automation – Minimizing the need for manual intervention through smart processes.
Integration – Connecting with OSS/BSS, GIS, and enterprise systems.
Its “intelligent” design makes ONMSi ideal for multi-vendor, multi-technology optical networks, making it a popular choice among operators globally.
Breakdown of ONMSi Solution Architecture
The ONMSi solution architecture revolves around the ONMSi server, which works with clients, controllers, notifiers, and OSS/GIS interfaces through a corporate IP network. Let’s go through it step by step.
The Core: ONMSi Server
At the heart of it all is the ONMSi server, which includes:
ONMSi Server Software – The core platform for managing alarms, configurations, and performance data.
Database Layer – Responsible for storing logs, event histories, topology data, and user records.
The ONMSi server acts as the control hub, coordinating with all components and allowing for real-time monitoring, analysis, and reporting.
Interfaces and Controllers
The ONMSi server connects to several specialized modules:
a. Mobile Phone Interface (WAP)
Provides remote access via mobile devices.
Utilizes Wireless Application Protocol (WAP) for lightweight and secure connections.
Great for field engineers needing live fault updates.
b. Alarm Notifier (Email, SMS, etc.)
Sends real-time fault notifications.
Supports various channels:
Email for detailed fault information.
SMS for urgent alerts.
Helps lower Mean Time to Repair (MTTR) by ensuring quick responses.
c. OTU Controller
Oversees Optical Transmission Units (like OTU-5000, OTU-8000).
Offers fault detection, provisioning, and performance monitoring at the optical transport layer.
Connects hardware with the ONMSi software platform.
d. User Interface (HTTP)
A web-based client dashboard accessible through browsers.
Features:
Topology maps
Alarm/event monitoring
Device management
Performance reports
e. OSS/GIS Interface (SNMP, Web Services)
Links ONMSi with higher-level systems:
OSS (Operations Support Systems) for workflows and service provisioning.
GIS (Geographic Information Systems) for visualizing location-based assets.
Uses SNMP, APIs, and web services for communication.
Connected External Components
The architecture integrates external elements through the corporate IP network:
OTU-8000 and OTU-5000 – Managed optical transmission units.
E-Mail Server – Sends out alarm messages.
ONMSi Web Clients – Allows remote access to dashboards via browsers.
OSS/GIS Systems – Utilize ONMSi’s data for enhanced telecom operations.
