As a more important point, a diagnosis must consider a visual recognition of the active and passive elements of the network to rule out a physical failure of the network in the first instance and to be able to concentrate efforts on the review by segments and parts of the network, both the configuration and the infrastructure. The use of technological tools exponentially decreases the diagnosis and understanding of the systems. Additionally, having documented and updated documentation regarding network diagrams helps immensely for a quick diagnosis. Finally, using a system simulator helps to know and simulate failures before they occur in order to have a better understanding of abnormal behavior.

Fortunately, there are international standards for the development of network engineering and documentation. This allows for more efficient communication of technical aspects that pertain to the development and diagnosis of networks. The best way to communicate a solution is by using these standards, both in terms of nomenclature, diagrams, symbols, etc., which allow for more effective and assertive communication of solution ideas.

Implementing telecommunications solutions in an already operational environment is a challenge. Interdepartmental communication is vital for good coordination and implementation development. An activity plan should be considered, detailing the role of each person or team, considering start and end times and a good understanding of how these activities are linked in a plan. For this purpose, there are software and digital tools that facilitate this coordination and communication between areas. A failback plan should be considered in case something does not go as planned and disrupt the operation as little as possible. The implementation should be planned starting in the least vulnerable areas.
