IPC: H04M1/272
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To send a called subscriber telephone number after transmission of a dial tone to an exchange even in the case of the called subscriber telephone number dialed before the transmission of the dial tone from the exchange. SOLUTION: A dial tone sent from an exchange to a telephone set 1 is detected by a dial tone detection section 21, a called subscriber telephone number entered by a dial-key from a dial key section 22 independently of the detection is temporarily stored in a memory section 23 under the control of a dial transmission control section 24 and read first from the memory section 23 under the control of the control section 24 after awaiting a dial tone detection output from the dial tone detection section 21 and sent to the exchange. Thus, wrong dialing is surely prevented.
