Infrared hookswitch for a telephone
First Claim
1. An optical hookswitch assembly useable on a telephone set as an optical communications port, comprising:
- light emitting and detecting means so disposed in said telephone so as to detect the presence of a handset;
processor means connectable to telephone circuitry means and said light emitting and detecting means, said telephone circuitry means being activated by said processor means when said light emitting and detecting means fails to detect the presence of said handset, said light emitting and detecting means being useable as an optical communications port for accessing said processor means, by allowing an external computer to communicate with said processor means via optical coupler means.

Abstract
An optical hookswitch assembly useable on a telephone set as an optical communications port is disclosed. The hookswitch assembly is comprised of light emitting and detecting diodes so disposed in the telephone so as to detect the presence of a handset. A processor connectable to the telephone circuitry and the light emitting and detecting diodes is provided such that the telephone circuitry is activated by the processor when the light emitting and detecting diodes fail to detect the presence of a handset. The light emitting and detecting diodes are useable as an optical communciations port for accessing the processor by allowing an external computer to communicate with the processor via an optical coupler.
