As described above, after registering the first dial, one of confidential transmission, relay broadcast instruction, and second dial can be selected and registered.

If the registration of the telephone number is not selected in S54, it is determined whether the operation of the one-touch dialing or the speed dialing is selected (S88). The signal level of the signal 44a is set to "1", the CML is turned on (S92), the corresponding data of the registration circuit 42 is input, and a call is made to the first dial designated by the calling circuit 26 (S94).

Then, it is determined whether the called party is busy (S96), and if not, communication is executed (S98). This communication is performed by the registration circuit 4
2, based on various data such as the destination abbreviation, the start transmission speed, the confidential transmission, and the relay broadcast instruction registered as described above.

If busy in S96, the CML is turned off (S99), the retransmission counter for counting the number of calls is cleared (S100), and after waiting for two minutes (S102), the CML is turned on. (S103).

Next, the control circuit 44 inputs the data of the registration circuit 42, and
A call is made to the t dial (S104). Then, it is determined whether the other party is busy responding to this call (S106),
If it is not busy, communication is executed (S108).
This communication is performed based on various data such as the destination abbreviation, the start transmission speed, the confidential transmission, and the relay broadcast instruction registered in the registration circuit 42 as described above.

If it is busy in S106, the CML is turned off (S109), the data of the registration circuit 42 is inputted, and it is checked whether or not the 2nd dial is registered at the designated destination (S110). If it is registered, after waiting for 10 seconds (S112), the CML is turned on (S113), and the corresponding data of the registration circuit 42 is input,
A call is made to the second dial specified by the calling circuit 26 (S114).

Then, it is determined whether or not the called party is busy (S116), and if not, communication is executed (S108).

If busy in S116, the CML is turned off (S117), and the retransmission counter is incremented by one (S118).

If the second dial is not registered in S110, the retransmission counter is incremented by one (S118).

Then, it is determined whether or not the value of the retransmission counter is 2 or more (S120). If the value is 2 or more, the process returns to S52. If the value is less than 2, the process returns to S102 to perform retransmission. .

The embodiment of the present invention has been described above. However, the present invention is not limited to this, and for example, the following modifications are possible.

First, in the above embodiment, the data to be registered in the one-touch dial or the abbreviated dial is assumed to be information common to the first dial and the second dial, assuming a destination abbreviation and a start transmission speed, and as information only for the first dial. Although confidential transmission and relay broadcast instruction are assumed, other information may be used.

In the above embodiment, when the confidential transmission or relay broadcast instruction is registered, the registration of the 2nd dial is disabled uniformly. Is registered, the operator is asked if the terminal to be registered in the next 2nd dial has the same function as the terminal to be registered in the first dial, and the response by the affirmation key from the operator is performed.
The registration of the second dial may be permitted.

FIG. 5 is a flowchart showing the control operation in this case. In FIG. 5, FIGS.
3 shows a portion different from the operation shown in FIG.

First, after registering the confidential transmission in S74, a message asking whether the second dial has a confidential communication function is displayed on the display unit 40 (S13).
2) Wait for an operator response. Here, the positive key 36
Is pressed (S134), registration of the second dial is performed (S138), and the operation shifts to S88 and subsequent steps. When the negation key 38 is pressed, 2n
The process proceeds to S88 and subsequent steps without registering the d-dial.

If the confidential transmission is not registered as described above and the relay broadcast instruction is registered in S82, it is asked whether the second dial has the relay broadcast instruction function. The message is displayed on the display unit 40 (S1
44), waiting for the operator's response in S134 and S136, registering the second dial only when the affirmation key 36 is pressed (S138), and proceeding to the operation from S88 onward, and pressing the negative key 38. 2n
The process proceeds to S88 and subsequent steps without registering the d-dial.

In this way, it is possible to perform proper confidential transmission and transmission by registering a relay broadcast instruction even to a proxy destination by registering the second dial.
