Stable AV Equipment for Network Operation Centers

What is a Network Operation Center?

The telecommunication industry and the technologies of communication among private people and industrial entities are emerging rapidly. Large communication networks have been implemented all over the world to serve the need of data and voice transfer by mobile operators. Such complex networks may serve an entire country and so must have an NOC to supervise and manage such operation.

Generally, a Network Operations Center (usually called as NOC) defines a centralized location from which network monitoring; controlling and management are exercised by operation staff continuously in 24/7 all year around.

They supervise these networks, servers, databases, firewalls and any related services or performance issues of these. Examples can be like mobile phone operator’s service, management of large communication network of a large operator or country, traffic control centers, network of emergency services or utility providers.

Why and where do we need Network Operation Centers?

NOCs are implemented by business organizations, public utilities or government agencies that require highly available telecommunication service by complete and reliable supervision. NOC personnel are responsible for monitoring large communication networks for certain conditions that may require special attention for reliable operation to avoid degraded service. In telecommunication environments, NOCs are responsible for monitoring power failures, communication lines, communication alarms and other performance issues that may affect reliable network operation.

Why do we need a video wall in a NOC?

Efficient and reliable operation must be backed by easy-to-process statistic illustrations, displaying data collected from the fields. NOCs are usually equipped with a central video wall to display and to share data among all the operators sitting in rows of desks in front of the video wall. These operators are facing the video wall which typically shows details of general network performance, statistical data about operation, ongoing incidents or significant alarms.

Technicians usually have several computers and monitors on their desk for the supervision of certain part of operation. The NOC must be equipped with the video wall, operators with different responsibilities and professional telecommunication network supporting interaction of operators with each other and with information over the video wall.

What components and equipments are needed?

Well-operated NOCs need complex system of different equipment that must support supervision of reliable operation. The video wall is the central information board for the staff to supervise and to share information among each other. The large surface of the video wall can be implemented by different technologies.

  • These days, an array of TFT LCD monitors with a rather thin bezel are mostly used. The information over this video wall must be displayed in any size and any position regardless of the monitors’ borders. The usual TFT/LCD monitors must have high brightness and protected against burn-in during constant operation. The monitors deliver FHD or UHD resolution.
  • The monitors must be fixed to a system of stands that support video wall build and even precise alignment of neighboring monitors.

  • The LCD wall means an emerging technology that is composed of LCD modules that have no gap between the modules. The pixel pitch of such modules limits the total resolution of the wall but they support building of rather large walls.
  • Rear projected cubes represent an elder technology but have still role in mission critical control rooms as they have very small bezel and really support 24/7 operation. The laser technology ensures long life time and high color uniformity.

  • The operators usually have multi-headed operator PCs displaying network information and control layouts. These PCs use standard Windows operating system for general compatibility with all the operators and the video wall.
  • The display and information management over the video wall is implemented by the custom video wall controller. This is connected to the operator PCs, to the external network and drives the video wall.The video wall controller is the critical central element of the NOC and provides outstanding services for the operator cooperation and reliable information management.
  • Complex and reliable local area networks must be applied for the interconnection of the operator components, the video wall controller and the external world. Hierarchical operator rights and sophisticated network security must be implemented by routers and fire walls.
  • Usually, an un-interruptible power supply system must ensure continuous operation of all the components of a certain NOC in case of power cut. The stable power supply must have external batteries or even a generator that is capable to generate the mains power in case of longer interrupt in the operation.

How to control video wall information in an NOC?

Customized AV solution needs to be installed to control all crucial aspects of a 24/7 operation without any issue in order to manage a given video wall in such an environment. The video wall controller needs to be able to display and to share the following input data and information over a video wall:

  • screen content of any operator workstation’s screens
  • live video of satellite receivers or Blu-ray players
  • graphics information through locally run web browsers
  • display graphics of local Windows applications rendering statistical data

The operators’ screens contain critical information for the center’s audience and so the application windows can be drawn to any position or any size over the video wall. Additionally, real time scaling must be applied for the perfect visual experience of the audience. Leading edge of unlimited scaling and real time display of directly connected video information is a must have in such installations.

This is a success story about the replacement of an outdated video wall which was aging 15 years. TIM management entrusted DEXON Systems to integrate DXN5200 to control LED monitor system with ultra-light frame and outstanding signal management. Dozens of operators can take advantage of a video terminal that stands out on the front wall on an area of almost 50sqm, to be used in the most varied ways to easy successful operation daily.

The control and signal management has been entrusted to a well-known and widely used device, the DXN5200, which in addition to the management of the LED wall is notoriously capable of performing various functions, thanks to the ability of processing and displaying multiple analog or digital inputs, SD or HD, local or remote video inputs, 4K inputs, IP cameras and workstation monitor images.

This is an installation example of an actual progress of installing the largest video wall in Poland with its grandiose size of 92 square meters and our DXN5200 controller was customized to this project.

This is a real mission critical control room providing complex services for reliable operations. With its 3x34 monitor layout serving 92 square meters, this video wall operates 24/7 to enhance efficiency and quality of telecommunication services in the entire country. Four different departments use the large area of 40-meter-wide video wall employing altogether 150 operators who are responsible for different aspects of operation.

What kind of solution does DEXON Systems offer?

DEXON Systems’ video wall controllers drive multiple screens to form a large Windows graphics desktop where graphics and live video overlay windows are displayed in real time. This enables an easy-to-use user interface to all operators. Graphics application windows, direct signal inputs and network-based information can be managed by remote operators through this professional platform for centralized supervision in network operation centers.

The layout management must be able to handle this huge area and must be able to control, save and recall previously defined layouts. By just a few mouse clicks the full layout can be changed, displayed or saved. Such a rather complex system works with several different layouts that must be changed on frequently changing requirements during daytime or during the night. Some mouse clicks and the wall content must be changed to a brand-new layout within a fraction of a second.
