This paper provides a case study of possible network evolution steps on an actual node; and then looks at the Total Cost of Ownership (TCO) for each option. This will show others the same steps that nbn went through in their decision-making process. The three approaches considered are:
The paper also considers network power consumption, material and truck roll costs for actives, passives, fiber and coax maintenance, as well as for the drop line maintenance and replacement, and give overview on how to make estimates for the costs over an extended period of performance.
