ABSTRACT:
A cutover or reconnection LRD device capable of being remotely controlled has been developed. The cutover or reconnection device consists of a switch under control of a control circuit which can receive tone or other special signals sent remotely, such as via the network from the central office, or via portable devices. In response to those signals, the control circuit changes the state of the switch, thus connecting the subscriber to either the old electric telephone circuit, or the new network circuit. In the below-described preferred embodiments, the latter circuit may be a fiber optic circuit or a broadband or CATV circuit, for example.
