This paper proposes a new sharing of call processing functions between a terminal and a switching system, taking recent technology advances into consideration. Information and its processing in an electronic switching system are defined and their calculation method is shown to discuss the function share. Numerical examples of information and its processing amount are obtained using NTT's commercial system, D-10, for an example. Possibility of function distribution to a subscriber terminal is discussed, based on information and its processing amount obtained by the analysis. The amounts of information and its processing in an existing switching system are estimated to both be reduced to about 35 percent by distributing to a terminal function, such as subscriber's action detection, audible signal generation, dialed number storage and display and so on. On the other hand, the information and its processing amount shared by the functional terminal are estimated to amount equivalently only to 5 and 10 percent respectively of those of an existing switching system, because introduction of functional terminals eliminates conventionally required time urgent information processing. Therefore, the total information and its processing amount in the telephone system incorporating functional terminals are estimated to be about 40 and 45 percent of those solely shared by an existing switching system, respectively. It is also mentioned that the functional terminal guarantees the variety of services which enables economical use of the telecommunication network.
