Personal conditional discrete communications system having two way directional connections/man machine interface with processor identifying caller from memory base/initiating connection/activating man machine interface.

摘要

The communications unit has two way directional connections (2,3a,3b) with distant units and a man machine interface (5,9). A processor (1) identifies the caller by searching in a memory for the caller identity and where successful initiating connection, activating the man machine interface to signal successful connection.
