SOLUTION: The converter is a key telephone master controller 1 having an analog interface function and called from both a key telephone set 2 itself and an analog device 3 and provided with a master set control section 14 which distinguishes only off-hook information of the key telephone set 2 from off-hook information of the analog device 3 so as distinguish call information of the key telephone set 2 from call information from the analog device 3 thereby controlling the key telephone set 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control apparatus for a key telephone apparatus having an analog interface function.

[0002]

2. Description of the Related Art A conventional control apparatus for a key telephone apparatus of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 6-216882.

According to these conventional control devices for a key telephone device, when a dial is pressed on the key telephone,
The information is also transmitted from the key monitoring unit provided in the key telephone to the key telephone control unit, and the key telephone control unit listens to the caller as a key-in tone as a key-in tone via the communication circuit unit in the key telephone. And at the same time,
Dial information is also transmitted to the key telephone interface and the main unit control unit in the key telephone main control unit via the main unit interface in the key telephone main control unit connected to the office line. In this case, when the dial is pressed against the analog device, the monitoring is performed by the analog interface, the information is transmitted to the key telephone controller of the key telephone, and the main device interface in the key telephone main controller is controlled. , Dial information is transmitted to the key telephone interface and the main device control unit.

[0004]

However, as a method of transmitting information at the time of transmission from the key telephone to the key telephone main controller, a command which is a serial signal is performed. It is necessary to distinguish outgoing information from an analog device from outgoing information from "off-hook" to "dial"
"On hook" and the command for each event,
It is prepared for a key telephone as shown in FIG. 3 and for an analog device.

In other words, when making a call from a key telephone,
"Off hook" raises "10", and subsequent "dial" raises any command from "20" to "D0". Then, “00” goes up by “on hook”.

On the other hand, when a call is made from an analog device, "11" is raised by "off-hook", and then any command from "21" to "D1" is raised by "dial". "On hook", "01" was going up.

Therefore, in the above-mentioned conventional key telephone controller, the number of commands used for communication between the key telephone and the key telephone main controller is very large, and in terms of effective use of resources such as memory. There was a problem.

An object of the present invention is to provide a key telephone control device which simplifies commands used in communication between the key telephone and the key telephone main controller and makes effective use of resources such as memory. The purpose is.

[0009]

SUMMARY OF THE INVENTION In view of the above-mentioned object, the present invention distinguishes between off-hook information in a key telephone and off-hook information in an analog device only, thereby enabling transmission from the key telephone or transmission from the analog device. A main unit control unit that controls the key telephone by discriminating between information and information is provided to simplify commands used in communication between the key telephone and the key telephone main controller, and to make effective use of resources such as memory. I tried to use it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The key telephone controller according to the first aspect of the present invention has a key telephone main controller having an analog interface function and capable of transmitting signals from both the key telephone itself and analog equipment. A main unit control unit that controls the key telephone by distinguishing between the transmission information from the key telephone and the transmission information from the analog equipment by distinguishing only the off-hook information and the off-hook information in the analog device. Features.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram showing an embodiment of the present invention.

According to this, reference numeral 1 denotes a key telephone main unit, which includes a power supply unit 17, a central office interface (i / f) 1
5. It is composed of a key telephone interface (i / f) 16 and a main device control unit 14, and realizes a key telephone function with the office line 18.

Further, the main unit control section 14 comprises a number plan processing section 11, a dial transmission section 12, a transmission restriction processing section, and the like, and performs processing for dial key information from the key telephone 2.

The key telephone 2 comprises a power source 6, a key telephone controller 5, a communication circuit 9, a main unit interface (i / f) 4 and an analog interface (i / f) 10. The control unit 5 controls the display unit 7 and the key monitoring unit 8, the analog interface unit 10 is connected to the analog device 3, and the communication circuit 9 includes a handset 19 as a communication device and a speaker ( SP) 20 and a microphone 21 are connected.

The operation in the above configuration is as follows. That is, when a dial is pressed on the key telephone, the information is transmitted from the key monitoring unit 8 to the key telephone control unit 5, and the key telephone control unit 5
, The caller hears a confirmation tone as a key-in tone.

At the same time, dial information is transmitted to the key telephone interface 16 and the main device controller 14 via the main device interface 4 of the key telephone main device 1.

When a dial is pressed on the analog device 3, the monitoring is performed by the analog interface 10 and the information is transmitted to the main device control unit 5,
Dial information is transmitted to the key telephone interface 16 and the main device controller 14 in the key telephone main controller 1 via the main device interface 4.

As a method of transmitting the information at the time of transmission from the key telephone 2 to the key telephone main controller 1, the transmission is performed by a command which is a serial signal.

This command is transmitted to the key telephone 2
In this embodiment, the command is as shown in FIG. 2, which is distinguished from the information transmitted from the analog device 3 and the information transmitted from the analog device 3.

According to FIG. 2, when a call is originated from the key telephone 2, the key telephone 2
When calling from, "10" goes up with "off hook",
In the subsequent "dial", any command of "D0" is raised from "20". And "off hook"
"00" goes up.

On the other hand, when a signal is transmitted from the analog device 3, the "1"
"1", followed by "dial" and "on-hook"
Is the same as “2” when making a call from the key telephone 2 described above.
“0” to “D0” and “00”.

This is because the main unit control unit 14 in the key telephone main control unit shown in FIG.
It can be realized by managing the data from the analog device 3.

Therefore, in the number plan processing section 11, the dial transmission section 12, the transmission restriction processing section 13 and the like in the main apparatus control section 14, the conventional control apparatus can be used.

[0025]

As described above, according to the present invention, by distinguishing only the off-hook information in the key telephone and the off-hook information in the analog device, it is possible to distinguish the transmission information from the key telephone or the transmission information from the analog device. It has an advantage that it can be configured to include a main control unit that is separately controlled to simplify commands used for communication between the key telephone and the key telephone main controller, and that resources such as a memory can be effectively used.

Further, according to the present invention, even when an analog interface function is added to a key telephone device having no analog interface function, a command which is a communication means is not provided for each key telephone device. By distinguishing only the "off-hook" information and sharing information such as the dial key, the additional processing of the main unit control unit in the key telephone main controller and the key telephone control unit of the key telephone is minimized. Can be.
