Abstract: PURPOSE:To allow the operator to dial without being conscious of the system of an exchange by allowing a control section to check the reply of an exchange to the first number of a telephone number to apply subsequent processings automatically. CONSTITUTION:When the operator operates a hook switch 9, a line 8 is short- circuited, an exchange 9 detects it to send a dial tone. A dial tone detection circuit 4 detects the tone and recognizes the reply of the exchange 9.
