〔Example〕

Hereinafter, details of the present invention will be explained with reference to figures showing examples.

FIG. 1 is a block diagram of a functional telephone, in which a line terminal 2 to which a telephone line (hereinafter referred to as line) 1 is connected is shown.
The switch HS ¹ and relay SP contact sp

is connected, and a dial signal sending circuit (hereinafter referred to as DSS) 4 and a monitor speaker circuit (hereinafter referred to as SPC) 5 are connected in parallel, and when an off-hook is performed, TKC3 is connected to line 1. As a result, the DC loop is closed and the line 1 is captured, so that the DSS 4 can freely send a dial signal, and in response to a response from the other party, a call is made using the handset 6.

In addition, a processor (hereinafter referred to as CPU) 7 such as a microprocessor is provided, and this is equipped with a fixed memory (hereinafter referred to as ROM) 8 and a variable memory (hereinafter referred to as RAM) 9, as well as a dial key (hereinafter referred to as RAM). DK) 10, a redial key (RDK) 11 used as a specific key, a speaker key (SPK) 12, and a switch HS ² are provided, and the CPU 7 is activated according to these outputs. Execute the instructions in ROM8,
Control decisions are made while accessing predetermined data to the RAM 8, and control of the dial signal generation circuit (hereinafter referred to as DSG) 13, SPC 5, and relay SP,
It also controls lighting of the speaker indicator light (hereinafter referred to as SPL) 14 when the SPC 5 is in an operating state.

Therefore, after performing off-hook, DK1
If you operate 0, CPU7 will switch to DSG1 accordingly.
3, a dial signal using a composite audio frequency signal or a pulse signal is sent via the DSS 4, and manual dialing is performed in off-hook dial mode. Each time a manual dial call is made, the CPU 7 reads out the latest dial number that is sequentially updated and stored in the off-hook re-dial memory area in the RAM 9, and the CPU 7 controls the DSG 13 accordingly. A retransmission operation is performed depending on the mode.

On the other hand, without off-hook, SPK1
If you operate 2, CPU 7 will relay accordingly.
In order to drive the SP, bring the SPC 5 into operation, and turn on the SPL 14, a DC loop is closed via the contact sp, enabling on-hook monitoring by the speaker 15, and setting the on-hook dial mode. Manual dialing by the DK 10 or re-dialing by the RDK 11 is performed in the same manner as described above.

However, in this case, each time a special dial is made in the on-hook dial mode, the dial number that is sequentially updated and stored in the on-hook redial memory area in RAM9 is used for redialing, and the on-hook dial mode in
When the RDK 11 is operated, the CPU 7 reads from the on-board redial memory area, and the CPU 7 controls the DSG 13 accordingly.
A re-call operation is performed using the on-hook dial mode.

Figure 2 is a flowchart of the control situation by the CPU 7, and "SPK operation?" 101 is N (NO).
If so, the "Off-hook?" step 102 is determined according to the output of the foot switch HS ² , whereas if step 101 is Y (YES), the "On-hook dial mode setting" 102 sets the on-hook dial mode flag. is set, and
The relay SP is driven, the operating state of the SPC 5 is set, and the SPL 14 is turned on.

Next, "DK operation?" 111 is checked, and if this is N, "RDK operation?" 112 is checked.
becomes Y, in response to step 103, a determination is made as to ``On-hook dial mode?''121;
According to Y, the on-fucks dialing memory area in RAM9 corresponding to the on-fucks dialing mode "Read dial number from ONME"
122, when step 121 is N, it is off-hook dial mode, and for this, off-hook re-dial memory area "Read dial number from OFME" 12 in RAM9 is executed.
3, and thereby controls the DSG 13 to perform "redial transmission processing" 124.

Also, when step 111 is Y, the same as step 121 asks "On-hook dial mode?"
131, and if it is Y, perform the "manual dialing process/processing" according to the operation of the DK10.
"Update and store to ONME" 132 controls the DSG 13 to perform dialing in the on-hook dial mode, and sequentially updates and stores the dial number to be sent to the on-hook dialing memory area ONME in the RAM 9 one digit at a time.

On the other hand, if step 131 is N, the "manual dialing process/update storage to OFME" 133 is performed in the off-hook dial mode, and the DK
Along with dialing according to the 10 steps,
Off-set redial memory area in RAM9
The same update storage as described above is performed in OFME.

Next, if the other party responds in accordance with any of steps 124, 132, and 133, "call processing" 141 such as switching from on-hook state to off-hook state is performed, and then, by on-hook after the call or SPK 12 If "Call ended?" 142 becomes Y by re-operating "Recovery process" 14
3, each part is restored to its initial state.

Therefore, if you operate the DK10 after off-hook, step 111 will be Y and step 131 will be N, and a manual dial call will be made.
This dial number is stored in the off-hook re-dial memory area OFME, and once the on-hook sets step 142 to Y, the off-hook is performed again and the RDK 11 is operated.
12 becomes Y, step 121 becomes N, the dial number of the area OFME is read out in step 123, and the call is made again in step 124.

Also, if you operate SPK12 and then DK10 in the on-hook state, step 111
If 131 is Y, the dial number is stored in the on-box re-dial memory area ONME along with the manual dialing, and step 142 is set to Y by re-operating the SPK12, and then
When the RDK 11 is operated after operating the SPK 12 to set the on-hook dial mode, step 121 becomes Y and a re-call is made using the area ONME dial number.

For this reason, for example, if you make a dial call using on-hook dial mode and the other party is busy, you can then dial the other party using off-hook dial mode and make a call.
After this is completed, it is possible to dial the first party using the on-hook dial mode.
