Powering telephony on coax networks-a guide to dimensioning

This paper describes a methodology for use in dimensioning the power requirements for the provision of telephony over coaxial cable networks. A model describing the distributed power system elements in a coax network is presented. Guidelines are given for cost optimisation of the coax power network. An example of dimensioning the power for telephony on a typical coax network for a given grade-of-service is also presented.
