Cost analysis for HFC networks: installed first cost (IFC) for video and incremental cost (IC) for telephony

This paper presents the cost analyses required to ascertain the economic viability of HFC networks from the perspective of telephone service providers. The cost model for an HFC network delivering video is presented first in order for the installed first cost (IFC) for video to be computed. Using this HFC network as an infrastructure, the cost model for an HFC network with a telephone overlay is developed, and the incremental cost (IC) analysis for telephony is also presented.
