Abstract

PURPOSE:To attain the communication momentarily when busy state of both a sender side and a receiver side is released and to deliver a message timely by storing a caller number informed through a D-channel when the receiver side is busy and receiving polling after the release of the busy state. CONSTITUTION:When a destination receiver side terminal equipment 20 is busy, a transmission section 5 of a sender side terminal equipment 10 stores a transmission data 8 into a file 3 and sends a polling from the destination by a polling reception request. When a call is received while the receiver side terminal equipment 20 is busy, a reception section 15 stores a caller number 17 noticed through a D-channel of an Integrated Services Digital Network(ISDN) into a memory 6a and makes a call to the caller after the busy state is released to apply polling reception. Even when the destination is busy, since the opposite party makes polling reception after the destination busy state is released, the transmission data 8 is quickly sent.

In this embodiment, if the sending side is busy when the receiving side makes a polling call, the receiving side clears the calling number and cancels polling reception, and the sending side remembers the calling number that received the call while it was busy. However, if this calling number matches the destination number to which the call should be sent, an example will be shown in which the file is sent after the busy state is released. Therefore, if the receiving side is busy again due to this file transmission, the receiving side will make a polling call again, and by repeating this process, the moment both parties are no longer busy, one of them will make a call and send the message. will be communicated.

(2) If the other party is not busy, direct transmission is performed in which the document 40 is read and sent; however, if the destination is busy, the transmitting section 5 instructs the reading section 1 to read the document 40 and sends the read document. The data 8 is stored in the file 3, and the input destination number 7 is registered in the memory 6. FIG. 3 Step ■ (3) There is an incoming call on standby, and if it is a polling reception request, the memory 6 is searched, and if there is a called number 7 that matches the request source number, a file is sent to the called party. (Polling transmission) Step ■ (4) If there is no polling reception request, reception is performed (Step ■), but if there is an incoming call during this reception, the calling number in the D channel is memorized and registered in the memory 6. If the number matches the called destination number 7, a call is made to the destination after the reception is completed, and the file is transmitted.
