PROBLEM TO BE SOLVED: To provide a communication terminal equipment with energy-saving function preventing outputting of a calling sound more than a prescribed number of set times from an attached telephone set, when shifting to a normal power mode from a low power mode. SOLUTION: During operation in the low power mode, a control means 1 disconnects a telephone line L from the attached telephone set TEL. When a calling signal detection means detects the calling signal, the means 1 releases the low power mode to shift to the normal power mode, to connect the line L with the set TEL. After that, when the means 30 detects the calling signal prescribed times, the means 1 connects itself to the line L. |
