PURPOSE:To automatically send a service number after accurately confirming the connection of a call at the time of the batch input of a telephone number and the service number when receiving a service such as the answer system of a bank through the use of many kinds of terminal equipments connected to an ISDN. CONSTITUTION:First of all, a console 3 batch-inputs the telephone number and the service number of an opposite party. When a 'response' message from the ISDN is received through a circuit control part 5, CPU 1 confirms the connection of the call. Next, CPU 1 switches the service number to a DTM tone signal with DTMFLS 16 and automatically sends it to the ISDN through the circuit control part 5. Thus, even at the time of the batch input of the telephone number and the service number, the service number can automatically be sent after accurately confirming the connection of the call. |
