Abstract of the Disclosure An addressable CATV converter for connection with a remote headend in a cable distribution system includes a pro- grammable read-only memory in which a unique identification code for the converter is stored, and a random-access memory (RAM) which can be programmed with the unique assigned conver- ter address after the converter is installed at the subscriber location. The converter includes a data receiver which, when the converter is connected to the cable receives from the headend a unique preassigned address code corresponding to the unique identification code stored in the PROM. When the iden- tification code stored in the converter PROM is matched at the converter with the received identification code, the unique preassigned address code is stored into the converter RAM, thereby to enable the headend to thereafter efficiently com- municate with the converter. The invention provides an addres- sable converter in which a unique address can be loaded or stored from a remote headend controller. The converter need not be mechanically handled or mechanically modified after its manufacture.
