Remote Operation & Maintenance Managed Services (ROMM)
The Concept
The Remote Operation & Maintenance Managed Service (ROMM) model on the common definition is called Reliability-centered maintenance (often known as RCM), is a process to ensure that assets continue to do what their users require in their present operating context.
The aim is to achieve improvements in fields such as establishment of safe minimum levels of maintenance, changes to operating procedures – strategies and the establishment of capital maintenance regimes – plans.
The Remote Operation & Maintenance Managed Services increases cost effectiveness, machine uptime, and a greater understanding of the level of risk that the organization is presently managing.
This service can be used to create a cost-effective maintenance strategy to address dominant causes of equipment failure. It is a systematic approach to defining a routine maintenance program composed of cost-effective tasks that preserve important functions.
ROMM provides the operator with the opportunity to stay ahead of the competition by concentrating on the core business by reducing network downtime, improving service quality and quickly identifying the availability of resources.
Benefits of Service:
a) Reduced network operation costs
b) Strategically deployment of maintenance and repair processes
c) Attract & retain
d) Improved satisfaction
e) Getting the right competence, in the right place and right time
f) Reliable management
g) Fast, easy and cost effective launch of new services
h) Secure and predictable performance
The System
ROMM is a web based application developed to perform the managed services of MW Communication Networks. The system is built on top of the Element Management System (EMS)’s, the Management Modules and the Network elements being monitored.
The system is operating under two main concepts:
- Remote Monitoring, Operation and Maintenance of the Network with secure connections
- Remote ordering to the maintenance staff by tracking real time status using the web browser.
ROMM structure consists of 3 subunits:
- Regional Support Center
- Customer Network Operation Center (NOC)
- NEC’s Local Facility (NEC Engineer and/or Local Partner)
ROMM is uniting the 3 functions above under a single roof by managing the entire system on a platform so that the network can be operational in a high quality structure effectively.
Regional Support Center:
The Regional Support Center is established in the area of operation as technical service headquarters. SQL based Data-base server, Web server and Board screen are being deployed in the center. The SQL Data server will collect the data received from each NOC via App/Interface server and store it in to the database.
The web server in Center delivers the screen pages of ROMM status through web interface on both Regional Support Center and clients (both customer and local facilities). Delivery of alarm/events images and any topologies status is the duty of the web server.
Customer Network Operation Center (NOC)
As a part of the system, it is necessary to deploy Database and Application servers to the Customer NOC. The Database server will collect and store data sent/forwarded from each local EMS and NE and share the data with the SQL server at the Regional Center. The replication mechanism is applied between two SQL servers (Center and each NOC) in order to recovery data that may get lost due to VPN connection. The secured VPN connection is applied between Regional Support Center and NOC through a 1024 bits encryption.
The application server in the NOC provides an operation platform and acts as a set of ROMM package components accessible to the software through the platform itself. The operation method is like an extended virtual machine for the running applications, handling transparently connections to the local SQL database server at one side, and connections to the EMS at the other.
Since the SQL database server, Application server, the EMS in the NOC and the applications on each servers are inter-connectional, a single physical port and global IP allocation is sufficient at the Customer (NOC) side to complete the requirement of this application. This allocated port will be used to connect between Regional support center and Customer NOC for the purpose of ROMM operation.
NEC Local Facility
There is a built in Ticketing/Ordering Tool (In-Out Tracker) in ROMM, that enables the Local staff to act for emergency issues to engage locally as in;
- On site hardware replacement,
- On-site investigation,
- Cabling and equipment relocating
These kinds of processes will be directly written to the ordering message box through the pre-assigned WEB interface of the local engineer to be traced by the administration and customer.
The Structure & Service
The ROMM service is a combination of highly qualified involvement and a dedicated software tool that supports a set of activities to facilitate efficient management of a network based on;
- Fault management (including alarm handling, pin point advising, and trouble ticket/ordering management)
- Performance management (RMON, TX/RX Level measurement)
- Events
- Inventory management
- Troubleshooting
- Scheduled reporting
- Consultancy
- Network utilization
- Mediation device management
- Third-party applications management.
This dedicated software tool consists of components TMN architecture such as;
- Core（database, common services sub-operation tool)
- Communication interfaces (protocols and applications)
- GUI (Map, Web application, Fault Management).
Additionally, this tool is not only limited with Operation & Maintenance services by simply following up the historical concept. New services such as Alarm Correlation report, Service Impact Analysis, Topology Management, Database Management (KPI, Data mining), Task Automation and Configuration Management are introduced.
