Abstract

The current Plain Old Telephone System (P.O.T.S) network is responsible for transmitting line energy to power phones and other Customer Premise Equipment (C.P.E). The P.O.T.S network has the capability to detect line impairment and adjust its power source to prevent damage to itself and/or create a hazardous scenario for the Central Office (C.O.) or the residential user. (Line impairment could possibly be a foreign source of power that would conflict with the power source at the C.O.)
