Abstract

This system is for use by a visitor to a facility that has multiple occupants, public-subscriber or other phone service, and an individual phone outlet at each occupant's part of the facility. A microphone and speaker are provided so that a visitor seeking access can speak with an occupant. A communication circuit carries signals between (1) the mike and speaker and (2) the phone service--to enable the conversation through an individual phone outlet. Manual controls, preferably including a standard phone keypad, are positioned for use by the visitor. An electronic memory holds directory information, particularly including occupant names and corresponding dial-up codes. An LCD, behind a protective window, shows the visitor the directory data. Names and other directory data can be fed into the memory remotely, preferably through either: ordinary phone connections using standard DTMF signals--with automated confirmation of input data by a voice-synthesis chip--or a modem. Data can also be input through a separate local hand-held programing device, or a local computer communication port. The phone circuit, even when in use for visitor-occupant conversation, can be used for the remote input. The visitor selects an occupant by finding a name in the display and then dialing that occupant's code. A microprocessor reads the data from the memory, responds to the controls, and manages: the LCD to exhibit the data, the sequence of data exhibition, the circuit to initiate communication via the phone service, etc.
