PURPOSE:To perform interpretation simply, by temporarily storing the telephone number and the number of times of pushing of a push button type and directly using the content with a microcomputer, in an exchanger using the microcomputer for a market section. CONSTITUTION:When a caller hooks on, the caller is connected to an outgoing register of an exchanger and when the caller transmits the telephone number with push buttons, the number is applied to an input 110 of a frequency converter and a push tone decoder 111 discriminates the combination of frequency components of 12 kinds and generates an output. The output is converted into a 4-bit output being 1,2,4,8 code at an encoder 112 and its output is sequentially stored in registers 115-118. A control circuit 113 controls sequential reading to the registers based on the number of times of pushing obtained from a number of times counter 114. The content of the registers 115-118 and a counter 114 is directly supplied to the microcomputer for selective control. |
