Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a functional telephone that puts a telephone line on hold by a hold operation during a call and sends a hold melody to the put on hold telephone line.

[Prior art]

Conventionally, in this type of functional telephone, the hold melody is one fixed melody for each telephone, or at most a melody IC with two outputs is used, one of which can be selected manually by Kaneko, and there is little variation. However, it is not economical to record the complete history of numerous ICCs with various melodic strengths.

[Object and structure of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to provide a functional telephone that can change the hold melodies at will or obtain a variety of hold melodies.

In order to achieve such an object, the present invention provides a memory that sequentially stores all predetermined digits of a dial number input from a dial key, and a memory that sequentially and repeatedly reads out the dial numbers stored while the line is on hold at a predetermined speed. and means for transmitting a sound of a specific frequency corresponding to each read dial number.

That is, by changing the dial key input, a variety of hold melodies can be obtained. Hereinafter, the present invention will be explained in detail using Examples.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, reference numeral 11 denotes a bell circuit, which is connected to the office line terminal via a hook switch H8I as shown in the figure when the hook is on, and notifies the incoming call. 72 is a communication circuit, 1
3 is connected to the 9th station line terminal by hook-off, and calls can be made. 'i! , and 14 can make a dial call via the dial pulse generating circuit 15 by operating a key at 9172217 on the dial keyboard.

On the other hand, 16 is a well-known microprocessor-based control circuit, which includes key input from the dial keyboard 14, hook switch H82, and hold switch S.
Depending on the state of WI, control operations as shown in chart 70 in FIG. 2 are performed.

That is, when a shift off is detected by the hook switch H82 (step 101), the control circuit 16 checks whether there is any manual input on the dial keys, and if there is an input β (step 102), the contents of the built-in register N [N, ] to "0" (step 103), and then stores the dial number in address N of the read/write memory 1T (step 104).
), increment the contents of register N by "]" (
Step 105).

If there is further dial key power (step 106), repeat the same operation.

Thereafter, the call state is entered and the hook-off state remains (step 107). If a hold operation is performed using the hold button switch SWI (step 108), the control circuit 16
is the content of the built-in register M [IL] 't-"0" (step 109), and then the read/write memory 17
The content of address M is read (step 110), and the dialed number data is sent to the scale generation circuit 19 via the decoder 18, and a corresponding tone is generated. f, that is, the scale generation circuit 19 is the scale of do, shi, mi,...? The circuits that generate the respective tones that constitute the circuit generate the tones corresponding to the pitch names assigned to the dial numbers, respectively, in response to the signals corresponding to the dial numbers 0 to 9, which are V-converted by the decoder 18. The generated sound is sent to the =3-telephone @ line via the telephone communication circuit 12 (step 111).

While the hold state continues without the hold release operation being performed (step 1.12), the contents of register M are incremented by [1] (step 113) until CM] becomes equal to [N] (step 11. 4) Repeat the same operation until all the sounds corresponding to the dial numbers stored in the storage memory 17 are sent out.
Even if becomes equal to [N], if the hold release operation is still not performed, check the register again (evening
r OJ VCt, Te (Step 109) The same operation is repeated.

In this way, until the hold is released, all the stored dial numbers are read out in sequence and the corresponding numbers are continuously sent to the telephone line.

As explained above, during the first hold after starting an outgoing 4ti call, a hold melody that corresponds to the telephone number of the other party at the time of the initial dialing is normally sent out, but depending on the specifications, dialing during the call is allowed. The case is bad. That is, when the MF system is used, all data is sent and received using dial signals, and this embodiment also has such specifications. That is, step 108
If there is no hold operation in step ]-12, or if there is a hold release operation in step ]-12, the program is executed at step 106.
Return to , and check whether the dial key is manually operated.

If such a dialing call is rarely made during a call, in this embodiment, the number is sequentially stored in a predetermined location in the memory 1T, and a corresponding melody is added during subsequent hold calls.

On the other hand, after the hook-off (step 101), if there is no dial key power (step 102) and it is an incoming call response (step 115), the program execution moves to step 106. Therefore, in a subsequent hold operation, a melody corresponding to the dial number stored in the previous call will be sent out, but even during an incoming call, if a call is made during a call as described above,
At the subsequent hold, a corresponding melody is added.

If the incoming call is answered successfully (step 115), dial 7 dials (step 116) or dial manually (step 102).
) will be executed.

An example in which the hold melody changes automatically based on the dialed number has been described above, but the hold melody may be registered in advance manually using the dial keys while on-hook. In this case, you can memo I7 any melody, such as a phrase from a famous song or a song created by a subscriber.
It can be set freely within the range of 17 capacities. An example of this is shown in FIG.

That is, when an input from a specific function key, for example, the asterisk key 14A is detected during the 7-key turn-on (step 201) (step 202), the contents of the register N of the control circuit 16 are set to 'erOJ' (step 203).
. Next, if there is manual dial key power (step 204)
, store that dial number in the sound memory 17ON address (
Step 205).

While incrementing the contents of the register N by tr r I J (step 206), the dial numbers are sequentially stored in the memory 17 as long as the dial keys are pressed manually.

Therefore, by pressing the dial keys in an order corresponding to the arrangement of tones constituting a desired melody, the melody is stored as a corresponding arrangement of dialed numbers.

Therefore, if there is a hold operation after 7 requests (step 201) (step 207), the contents of the built-in register M [M] 'i rOJ are entered as described above (step 208), and the hold release operation is executed as described above. Repeatedly send out the melody memorized up to (steps 209 to 21)
3).

In this case, if it is possible to register all melodies by directly operating the dial keys "0" to "9", there is an inconvenience that the melody will be changed immediately if the dial keys are accidentally touched during hook-on. However, as described above, such inconveniences can be completely avoided by assuming that a specific function key is operated as the first instruction to register.

In addition, in each of the above-described embodiments, when registering a melody, the old contents of the memory 17 are left as is, and each time a new dial key is available, the new dial number is sequentially rewritten starting from the first digit. Contents of N [N] 'k "0" At the same time, note I
J17 may be cleared based on the content. However, in this case, for example, in the first embodiment, if the number of dialed numbers memorized after stopping dialing is extremely small, for example, one, and the subsequent incoming call is put on hold. etc., it can be said that it is not a melody, but is more like a tone signal.

Although the above description has been made regarding a single AT packing machine, the present invention is not limited to this, and it goes without saying that it can also be applied to, for example, a slave unit of a button telephone.

〔Effect of the invention〕

As explained above, according to the present invention, there is provided a memory for sequentially storing all predetermined digits of a dial number input from a dial key, and a means for repeatedly reading out the dial numbers stored while the line is on hold at a predetermined speed. By providing a means for transmitting a sound of a specific frequency corresponding to each dialed number read out, the hold melody can be arbitrarily set in advance and changed according to the dialed number, making it possible to create a variety of sounds. can be taken as a thing.
