Abstract

PROBLEM TO BE SOLVED: To receive a call to a facsimile equipment or a pushbutton telephone set by detecting a CNG only for a caller number being a CNG detection object when an incoming call reaches the pushbutton telephone set from an external line. SOLUTION: A facsimile equipment 12 and a pushbutton telephone set 13 are connected to a pushbutton telephone set 11, which is provided with a caller number detection section 14 detecting a caller number, a storage section 15 storing an external line caller number in common for a facsimile line and a general trunk line by one external line, a CNG detection section 16 detecting a CNG, and a control section 17 controlling the entire pushbutton telephone set. When a caller number detected by the caller number detection section 14 and the caller number stored in the storage section 15 are coincident at the arrival of an incoming call, the CNG detection section 16 detects the CNG and discriminates that the external call is a call to a facsimile equipment because the CNG is detected and the call reaches the facsimile equipment 12. When dissident, the external call is discriminated to be a general trunk line call and the call reaches the pushbutton telephone set.
