BASIC TECHNOLOGY

OF THE INTELLIGENT
COMMUNICATION SYSTEM

Intelligent telecommunications occur as follows.

(1) When a breakdown of or some congestion in a communication network
occurs, an action is taken to recover from the breakdown or congestion. This
requires knowledge of the breakdown or congestion, called a. production rule.
(2) For the design of telephone services, it is necessary to know about termi-
nal states or line states. Terminal states include the person-to-person, three-party
call, call forwarding variable, and call waiting states. Line states include the con-
versing, on-hold, and disconnection states. When a terminal is called and that ter-
minal has call forwarding variable service, the call is forwarded to the designated
terminal. The states are defined in a semantic network.
(3) Intelligent communication services include intelligent directory service,
intelligent switching service, and intelligent inquiry service. With intelligent direc-
tory service, the system, when asked in natural language for the phone number of,
say, Mr. Tanaka who lives in San Francisco, supplies the requested number. With
intelligent switching, service the system, when asked, say, "Please call Mr.Tanaka,"
