Method and apparatus for providing access to a secure region
First Claim
1. Apparatus for electronically controlling access to a secured region comprising:
- an audio transducer;
a DTMF decoder;
a processor connected to the DTMF decoder to receive DTMF signals therefrom;
a memory connected to the processor storing a code;
the processor comparing the stored code to the signal from the DTMF decoder and providing an access enable signal in response thereto;
a baseband signal output system for connection to a wall control of a garage door operator and for providing a baseband signal in response to the access enable signal; and
a radio frequency transmitter for providing a radio frequency signal to a radio frequency receiver of the garage door operator in response to said access signal.

Abstract
Apparatus for controlling access to a secure region has an audio transducer. A DTMF decoder is connected to the audio transducer. A processor is connected to the DTMF decoder to receive DTMF signals. A memory is connected to the processor storing a code. The processor compares the stored code to the signal from the DTMF decoder and generates an access enable signal in response thereto. A baseband signal output system for connection to a wall control of a garage door operator and for providing a base signal in response to the access enable signal. A radio frequency transmitter provides a radio frequency signal to a radio frequency receiver of the garage door operator in response to the access signal.
