Abstract

PURPOSE:To make a dialer device usable in a country, region, or exchange system, etc., having a different dial specification by adjusting the dial specification of the dialer device by means of a command from a CPU by making in advance several kinds of dial specifications selectable and settable by performing command control from the CPU. CONSTITUTION:A control circuit 5 decodes a dial specification setting command from the CPU 2 and a dial specification register 6 temporarily stores a decoded dial specification. The value of the specification stored in the register 6 is outputted from a dial signal generation circuit 7 as various time information, etc., at the time of making a call by dialing. At the time of setting a dial specification, a value is inputted as a command to a CPU interface circuit 4 from a CPU 2 through a host CPU interface 3. The value is temporarily stored in the dial specification register 6 under the control of the control circuit 5. At the time of making a call by dialing, the dial information temporarily stored in the register 6 is transmitted from a dial output terminal 8 as a dial signal.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone dialer device, and particularly to a dialer LSI in which the dial specifications are set by command control from a host CPU.

[Conventional technology]

Conventionally, as this type of telephone dialer device, there has been one shown in FIG. That is, the dialer LS11a
and the host CPU 2 are connected by the host CPU interface 3, and the dialer LS11a includes a key input circuit 4a, a control circuit 5a, and a dial signal generation circuit 7.
A dial signal is output as an output signal 8.

The key input circuit 4a of the stand-alone type dialer 1a that does not have the host CPU interface 3 is connected to the host CPU.
It is controlled from the U2 side, and the dial specifications are controlled by its dialer L.
All I had to do was use the default values built into S11a. Therefore, it has not been possible to set various dial specifications through command control.

[Problem to be solved by the invention]

The conventional telephone dialer device described above has dial specifications built into the LSI circuit as general fixed values, so it can be used within two regions of the country and exchanges that meet the specifications, but it can be used outside of that range. The drawback was that it could not be used in certain locations.

The object of the present invention is to eliminate such drawbacks and to provide a telephone for use in which dial specifications can be selected and set in advance within several ranges under command control from a CPU, thereby making it possible to correspond to any specification. The purpose of the present invention is to provide a dialer LSI device.

[Means to solve the problem]

The configuration of the present invention connects a host CPU and a CPU interface that exchanges data with the host CPU.
In a telephone dialer device configured by SI, the dialing rate, make-break rate,
Pulse/tone IDP time, tone output time, pause time.

The present invention is characterized in that the flush time and the like are input to the dialer LSI as a setting command from the host CPU.

In the present invention, a dialer LSI includes a control circuit that decodes setting commands from a host CPU, a dial specification register that temporarily stores dial specifications from this control circuit, and a time when a dial is issued according to the value stored in this register. It may also include a dial signal generation circuit for generating information.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

In this embodiment, the dialer LSII is connected to the host CPU 2 by the host CPU interface 3, and the dialer LSII includes a CPU interface circuit 4,
A control circuit 5 and a dial specification register 6 are included.

The control circuit 5 decodes the dial specification setting command from the CPU 2, and the dial specification register 6 temporarily stores the decoded dial specification. The specification value stored in this register 6 is output from the dial signal generation circuit 7 as various time information etc. at the time of dial transmission.

In this case, dialing for tone dialing or pulse dialing depends on the dialing rate, make-break rate, and pulse/tone IDP time leap.

Specifications including tone output time, pause time, and flash time can be set by command control from the CPU 2.

To set this dial specification, the host CPU 2 inputs the value to the CPU interface circuit 4 via the host CPU interface 3 in response to a command. Thereafter, it is controlled by the control circuit 5 and temporarily stored in the dial specification register 6.

At the time of dial transmission, the dial information temporarily stored in the dial specification register 6 becomes a dial signal and is transmitted from the dial output terminal 8.

〔Effect of the invention〕

As explained above, in the present invention, the dialer specifications can be set by commands from the host CPU, so even if the dialer specifications differ depending on the country, region, exchange, etc.
Dial specifications can be matched by commands from the CPU side, which has the effect of making the phone more versatile and market versatile.
