Hi friends..! Anyone have any info or scheme or diagram.. etc. about the difference between CPC circuiy and Revers polarity circuit in panasonic kx-ns500.
 
The difference is what the provider uses. Cpc is a signal that is sent by the exchange when the call ends. Reverse polarity is where the + and - on the pair of wires reverse when on a call and reverse back when the call is gone
