Abstract

PURPOSE:To transmit an original without repeating the transmission even in a busy state, by monitoring when the terminal of the remote side is under the busy state, and transmitting a call-back signal to a transmission terminal when said terminal is in an idle state to connect the signal by using the stored information. CONSTITUTION:When a facsimile terminal 1 of the transmission side gives a call, a circuit exchange connects an oscillation register trunk 7 to the terminal 1 to check the using state of a reception terminal 3 of a destination selecting signal. The terminal 1 is connected to a tone trunk 9 in a busy state to transmit a busy signal, and the terminal 1 is put under a transmission waiting state. A CPU10 detects an idle state of the terminal 3, therefore, reserves a circuit of the terminal 3. Then the CPU10 connects the circuit of a transmission terminal to a called trunk and transmits a call-back signal to the transmission terminal. Then the reserved circuit is connected to the called trunk with an answer signal of the transmission terminal, and the circuits of transmission and reception terminals are connected to each other via an intra-office trunk 6.

The NCU 18 makes a call in response to the request, and when the single line exchange detects the call from this terminal, it connects 0R, T7 shown in FIG. 1 to this terminal and enters a state of waiting for a destination selection signal. Next, the NCUCT 20 of the sending terminal 1 sends transmission destination information to the NCU 18, and the NCU 18 sends a destination selection signal to the network side. When the circuit exchange receives a destination selection signal from the transmitting terminal using the number 0RT7, the CPU 10 checks the usage status of the receiving terminal based on the number information. If the receiving terminal is empty, the sending terminal and l0 are exchanged using known exchange processing.
The link between T6 and the receiving terminal and RGT 8 is connected. Next, the RGT 8 sends a paging signal to the receiving terminal to indicate an incoming call. When the receiving terminal returns a response to the incoming call indication, CPU10 detects the receiving terminal's response via RGT 8, disconnects the link between the receiving terminal and RGT 8, and disconnects the link between the receiving terminal and IOT 6. Connect.

Next, the automatic retransmission method in this embodiment when the receiving terminal is busy will be explained. The process is the same as above until the operator inputs information from C0N511, the sending terminal 1 makes a call, and the destination selection signal is received at 0RT7 on the circuit switching side. At this time, the CPU 10 of the line exchange checks the usage status of the receiving terminal based on the destination selection signal, and if the terminal is busy,
The line exchange connects the TNT 9 and the transmitting terminal 1 and sends a busy tone to the transmitting terminal 1. The transmitting terminal 1 DIs the busy tone.
IT21 detects it and sends a busy signal to NC'UCT 20. When the NCUCT 20 receives the signal, the NCU
18 and sends a transmission postponement signal to 5IGCT19. 5IGCT 19 changes the state of the transmitting terminal to the transmission postponed state according to the signal, and
20, or receive a retransmission request signal from C0N51.
This state is maintained until an interrupt signal is received from 1.

On the other hand, the NCU 18 disconnects the line with the exchange in response to the line disconnection request from the NCUCT 20. Exchange CPU
10 detects that the line of the transmitting terminal is disconnected, and uses the known busy monitoring function technique to monitor whether the desired receiving terminal becomes idle. When the receiving terminal becomes free, the CPU 10 of the exchange reserves the line for the receiving terminal, connects the line of the transmitting terminal to the RGT 8, and sends a callback signal to the transmitting terminal. At the transmitting terminal, the NCU 18 detects the callback signal, and the information is transmitted to the NCUCT 20.

The CU 18 returns a response signal to the network side. Exchange CPU
10 detects a response signal from the transmitting terminal to the call-back signal, and then starts calling the receiving terminal. That is, the RGT 8 is connected to the previously reserved line and a calling signal is sent out. If the receiving terminal responds to this, the sending terminal.

When the transmitting terminal and the receiving terminal are connected in this way, a response signal is sent from the exchange to the NCU 18 of the transmitting terminal, and in response to this signal, the NCU 1 B sends a response signal to the NCU 18 of the transmitting terminal.
0 Sends a line connection completion signal to i. NCUCT20
Then, using this signal, a transmission postponement release signal is sent to the 5IGCT 19, and upon receiving this, the 5IGCT 19 cancels the transmission postponement state and starts procedure level communication with the receiving terminal.
