ABSTRACT:
A telecommunications system is disclosed which is user programmable permitting inter and intrapremises communications from existent two-wire telephone extension sets at a customer's premises. The system may be functionally described as a telephone call interceptor comprising a number of building blocks for providing a plurality of features which the existent telephone extension sets may not be capable of by themselves. A data processor (110) receives data input from an incoming ringing signal detector (140), a telephone signal receiver (115), a dial tone detector (160) or from an associated user-activatable data input device (117). Responsive to the data input, the data processor provides output through a speech processor (150), a telephone signal generator (116), a ring generator (119) or through an associated data output device (113) such as a loudspeaker. A peripheral device interface (114) connects data processor (110) to security, utility meter, fire detection, energy control, appliance and other devices.
