Abstract/Summary

An Intelligent Telephone System (ITS) is a telephone system which provides convenient communications services in a large area such as a distributed office environment with different branches. The ITS is designed to variably screen incoming calls at definite intervals of time and allows only those callers which it recognizes, depending on the presetting, to pass through and reach the owner of the phone. The ITS provides communication through the use of microprocessors to control the operations of telephones within a certain network for faster, accurate and more effective access. Each party that has an access to the system is given a unique number that will serve as their local code. This local code will be used to address the particular handset it is associated with. Intelligent Telephone System is developed to minimize needless access to the telephone. Using simple ID coding schemes, the ITS operates in three modes: the single priority, the multiple priority, and the open mode priority. In single priority mode, only one unique caller can access the called party's unit with a specified time interval. Multiple priority mode enables a definite number of distinct callers to access the unit within a specified time interval. As in the single priority mode, caller's identification code are stored in the receiving unit and all subsequent calls are checked against these. In the third priority, the open mode, no identification codes are needed, so any one can access the unit regardless of whether or not the caller has the project unit. Normal telephone operations therefore resume.
