First, the stored contents of dial memory α and table α9 will be explained.

Now, there are data telephones K, having the configuration shown in FIG. 1, with buttons A to D as shown in FIG.
Assume that there are three different telephone lines H1, H2, and H3, and the dial numbers of these lines are L, 2, and 3, respectively.

In this case, for example, as shown in FIG. 3, the dial memory α4 has a dial number device L, position 2 corresponding to the keys Cx:l, (2:l, (3)).

The dial number of the host whose protocol is different from that of the host α& is stored after the key “4”. Also, table a9 has a key [l].

(2: l, (3: For IK, [2] key, [3] key
, (1) Key code, 1:02), [:03)[
01] are stored respectively.

Next, the operation of this embodiment will be explained with reference to chart 70 in FIG. 4 showing the processing contents of the control unit αη.

In the following explanation, as shown in FIG. 2, data telephone B is connected to the telephone line H1 of host 211 at the switchboard, and data communication is attempted from data telephone A to host 211. In data telephone A, the data shown in FIG. 3 is registered in dial memory α and table α9.

First, press the [l] key, then press a predetermined function key, and then input data such as the date, credit number, amount, and password.

Then, press the dial key.

Then, in response to the key operation, the control unit αη changes the signal H8 to r
As a HJ, close the switch circuit (5) and open the telephone # (2).
Connect 1. Next, the dial number meter corresponding to the [1] key is read out from the dial memo IJ (141) and sent to the dial circuit (7), and the dial circuit (7) sends a dial signal corresponding to the position L to the telephone port #12)K. Send. In other words, dial the host (211 phone number #HIK. Then,
Set the timer circuit αa for a predetermined time T. During this period, the detection signals BT and C8 of the busy tone detection unit aa and the carrier signal detection circuit (9J are checked. In this example,
Since the telephone line H1 is already connected to the data telephone B, the detection signal C8 is not obtained, and a G-tone is generated when the exchange indicates that the telephone line is busy. Therefore, the detection signal BT becomes rHJ, and in response to this, the control unit αη turns off the switch circuit (5) by setting the signal H8 to rLJ,
Temporarily cut off the telephone line (2). Next, register α
90 content CNT is incremented and compared with a predetermined value CNTO, for example "3". In this case, C
Since NT=rlJ, the switch circuit (
5) is turned on, the telephone line (27t) is connected, the same dial number position L is sent again to the dial circuit (7), and the same dial signal is sent again to the telephone line (2). That is, redial is performed.

After this, the process returns to the step of setting the timer circuit [alpha] and checks the detection signals BT and C8 in the same way. In this case as well, if the call is busy, a second redial is performed in exactly the same way as the first redial. This 2
If the call is busy during the second redial, the contents of register α9 will be the predetermined value "3", so the control unit (17) will call K after cutting off the telephone line (2).

Referring to table 0S, the key code "02" stored for the rlJ key just dialed is read out, and the dial number position 2 corresponding to this key code is read out from the dial memory. And the contents of register a9 CNT
After resetting the switch circuit (5) and connecting the telephone line (2), this dial number position 2 is sent to the dial circuit (7), which then automatically dials the telephone port RH2.

In this case, line H2 is vacant, so the exchange (221
Now, when the host (211) and the data telephone A are connected in this way, the carrier signal sent from the modem (8) is transmitted to the host c211. received, host) (211
also transmits carrier signals to the data telephone. This carrier signal is detected by a carrier detection circuit (9), and the detection signal C8 becomes rHJ. Then, the control unit αD is
Data transmission is started in response to signal C8 becoming rHJ. That is, data entered from the keyboard a11 and stored in the RAM (13) is converted into a telephone signal by the modem (8) and sent to the host (211).The host (2υ) responds to the data telephone after receiving the data. After transmitting the message, the data telephone demodulates the response message into data using the modem (8), stores it in the RAM (13), and displays it on the display device (121).

By the way, at the exchange, when the telephone line (2) of the data telephone person is connected to the telephone line H2 of the host (211), if the line condition is bad for some reason, the carrier signal will be The timer circuit (1(l)
times out. When a timeout occurs in this way, the control unit (17) changes the content CN of register a9.
In the same way as when T reaches the predetermined value "3", the communication line (2)
After shutting off, table α5 is referred to. Then, the key code memorized for the [2] key you just dialed,
That is, "03J is read out, the dial number device 3 corresponding to this key code is read out from the dial memory I, and the telephone '
After connecting line (2), the telephone line H3 is automatically dialed.

Suppose that telephone line H3 was busy all three times.

Alternatively, if the connection status is not good, table a9 shows the key code "01" for the [1] key as opposed to the [3] key.
is written, automatic dialing to the telephone line H1 of the telephone is subsequently performed.

As explained above, if the same telephone line is busy even after dialing the specified number of times, or if the line is in bad condition even if the connection is established, please refer to the table (15I) and dial the telephone line to a different telephone line. In this embodiment, the number N of automatic dialing is counted by the control unit αD, and when the contents of a register (161) that stores this value reaches a predetermined value N, subsequent automatic dialing is performed. I am advised not to do this.

Incidentally, although the above description has been made using a data telephone as an example, the present invention can also be applied to a normal multi-function telephone that does not perform data communication. When it happens,
It is sufficient to start a voice call without detecting a carrier signal.

(G) Effects of the Invention According to the present invention, when one of a plurality of dial numbers owned by a called subscriber is dialed by key operation, the dialed telephone line is changed even after dialing a predetermined number of times. If the call is busy, a different dial number of the called party is automatically re-dialed, minimizing operator intervention.

Rapid dialing can be achieved by effectively utilizing multiple telephone lines of the called subscriber.
