ABSTRACT:
A telephone terminal equipment consists of a ring signal detecting circuit for detecting ring signals transferred from a caller, a ring tone generating circuit for generating ring tones output from a speaker when the ring signals are detected in the ring tone generating circuit, a telephone number detecting circuits for detecting a telephone number of the caller, a memory circuit for storing the telephone number detected in the telephone number detecting circuit, a ring signal termination detecting circuit for detecting termination of the ring signals in cases where a subscriber make no response to the caller, a control circuit for controlling the memory circuit to store a no-response code in relation to the telephone number in cases where the termination of the ring signals is detected in the ring signal termination detecting circuit, a displaying circuit for displaying both the telephone number and a no-response mark relating to the no-response code stored together in the memory circuit. Because both the telephone number and the no-response mark are displayed in the displaying circuit, the subscriber can judge whether a response to the caller is required.
