'''Cable telephony''' is a form of [[digital telephony]] over [[Hybrid fiber-coaxial|cable TV]] type networks. A telephone interface installed at the customer's premises converting analog signals from the customer's in-home wiring to a digital signal, which is then sent over the cable connection to the company's [[Cable television headend]] switching center. The signal is then sent on to the [[public switched telephone network]] (PSTN). Cable telephone provides another revenue stream for cable television system operators and gives the consumer the convenience of combing several services on a single bill - such as paid television, internet and telephone services.<ref name= RG00>  Richard Grigonis (ed) ''Cable Telephony'' in ''Computer Telephony Encyclopedia'', Focal Press, 2000 pp.68-69 </ref> At times in the industry this is referred to as "[[Triple play (telecommunications)|triple play]]".
