1.0 SUMMARY

The Czech Army owns a private telecommunications network for voice and data transmission. On the HW level, information is transmitted via microwave radio transmitters and receivers and optical cables. tThis telecommunications network, based on multiple vendor technology, needed an integration platform to unify network functionality management and surveillance.

2.0 CHALLENGE

The Czech Army chose ITC to deliver a management system for their network.

The main functionality of this management system was to configure and manage devices and transmission lines and monitor their status and the quality of services provided.

3.0 OUR SOLUTION
ITC's SOLUTION IS BASED ON THE VELÍN AND STARNET SELF-DEVELOPED SOLUTIONS.

ITC provides all necessary SW components - communication protocols, management of network nodes, network management. The system, implemented in the Czech Army, has also been implemented since 2000 in the Slovak Army under the name STARNET with some modifications (change of OS platform) and improvements. The Telecommunications Network Management system (TMN) is based on ISO-OSI norms and CMIP/CMIS protocol. The system manages microwave transmitters, PDH multiplexors and other devices, located on the territory of the regions of Bohemia and Moravia, on the HW level. The system supports their independent activity and monitors the parameters of the operations for the monitoring centre. Part of the system also includes planning, the automated generation and assignment of connection circuits, transmission quality control, transfer to backup operations etc.

The system is based on Open Standards. It is at the same time open to the integration of other devices and telecommunications technologies and can be integrated with other devices and management platforms (also enables the integration of support for devices and systems from different vendors).

The system tools enable network operators to:

• have an overview of network topology

• have an overview and see an inventory of existing lines

• create and maintain virtual circuits, manage interconnect

• set up the parameters for terminations (speed, interface type, ...) of the devices

• have a good overview of the device status via device reports and status attributes.

Status is presented in different colours on the topology maps and list of alerts

• have access to operational statistics according to the ITU-T G.821 norm and create graphs

• Starnet is currently modified to manage optical and radio digital network PDH and is integrated with HP OpenView.

• control and modify global device settings (access rights, statistics, ...)

ITC delivered the Velin system for the Czech Army in 1995. In 2006, Version 2 of the system, based on Starnet product, was implemented. This version runs on the Linux operating system with the newest version of HP OpenView. In order to enable a multiplatform environment, user interfaces were transformed from the original X.11 environment into a JAVA platform. The new version brought with it simplified system management and better integration with other transmission systems operated by the customer.

ITC provides ongoing maintenance services for this solution and supplies add-ons and modifications of the solution.

4.0 RESULTS

The Velín system enables the Czech and Slovak Armies to manage effectively one of its key wireless networks. Thanks to the distributed architecture and high robustness, the system minimizes the necessity of physical service interventions in remote locations. ITC has been maintaining and developing the system for over 10 years, following the latest trends and technologies.
