Assume we can build the fiber plant for 1 million USD (*). This fiber can
be depreciated over 25 years. That means we only take USD 40,000/year of

The copper plant is already there but the DSLAM is missing. Assume USD 100
per port plus USD 100 per DSL CPE. This equipment can only be depreciated
over 5 years. With 1700 ports this gives USD 68,000/year of the company
Not claiming these number are anything but fantasy as I know nothing about
