- 28 - 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 receives data input from an incoming ringing signal detector, a telephone signal receiver, a dial tone detector or from an associated user-activatable data input device. Responsive to the data input, the data processor provides output through a speech processor, a telephone signal generator, a ring generator or through an associated data output device such as a loudspeaker. A peripheral device interface connects data processor to security, utility meter, fire detection, energy control, appliance and other devices.
