I did a training the past week by Scientific Atlanta/Cisco. The training covered how to setup a Head End and use System Manager. System Manager is a server that manages analog cable systems, this managers everything down the line, it is the only machine you will ever need to manager over 500,000 analog cable boxes. This is a dead technology in the USA and Industrialized countries, but in 2nd world countries like Venezuela, Columbia, Dominican Republic, etc… Attached are the Pics of the system, the collocation/ Head End where we where working on and the system.
