DOCSIS\u00ae 3.1 and DOCSIS\u00ae 4.0 systems in combination with some legacy DOCSIS\u00ae 3.0 equipment still service millions of households in Germany and abroad, that need to be serviced and upgraded. For field engineers and techs, communications technology is getting ever more complicated to work with. However, in the end there is still only a 45-minute window given to complete the job. For a modern field engineer, it is imperative to understand holistically how modern communications networks operate, to keep up with technological advances and to incorporate it into the daily job on the network.
