Abstract

PURPOSE:To improve the operability of a key telephone set by identifying the class of trunk lines and PBX extensions, sending an abbreviation dial data read out of a memory section in the case of the trunk lines and adding a trunk line acquisition dial code of the PBX to a front part of the abbreviation dial data automatically in the case of the PBX extensions. CONSTITUTION:The class information of line wires connected to an line wire interface section 3, that is, a system data such as CO1 is trunk line and CO2 is a PBX extension, is stored in a main control section 6 via a key telephone set 2. The main control section 6 recognizes it to be a trunk line in the case of the CO1 and to be a PBX extension in the case of the CO2 based on the system data. Then an abbreviation dial data is read out of a memory section 7 in the case of the trunk line and sent to the line wire interface section 3 via a common bus interface 8. On the other hand, in the case of the PBX extension, the trunk line acquisition code ('0' domestic) of the PBX is added before the abbreviation dial data read out of the memory section 7 and the result is sent to the line wire interface section 3 via the common bus interface 8.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention accommodates multiple types of outside lines such as a central office line and a built-in PBX,
@Reduced dial transmitter wP, related to a complete button telephone device.

(Prior Art) Conventionally, button telephone devices in this trend have accommodated multiple types of external m' such as a central office line and a PBX extension line, and
A speed dial call is required for each extension.

(Problem to be solved by the invention) However, when making a speed dial call to a P'BX extension, in order to register a speed dial that matches the central office line,
There was a drawback that the BX central line acquisition dial (in Japan, it had to be dialed before the ``O''> yk speed dial.

SUMMARY OF THE INVENTION An object of the present invention is to provide a button telephone device with improved operability, which eliminates the need to dial the central line capture dial number of the PBX when making an @reduced dial call to a PBX extension.

(Means for Solving the Problems) In order to achieve the above object, the button telephone device according to the present invention includes an outside line interface section that accommodates multiple types of outside lines such as a central office line and a PBX extension, and an external line interface section for making speed dial calls. a memory section for accumulating and storing destination telephone numbers; a telephone interface section for accommodating a plurality of key telephones; and a ninth telephone line connected to the outside line interface section and the telephone interface section to form a complete communication path between the button telephone and the outside line. In a key telephone device comprising a route switching unit and a four-way telephone unit that performs control for forming a call path in a key telephone, and a plurality of telephones, each of the four parts of the outside line interface is connected to a telephone line. Information on the connected outside line is stored, and when the button telephone makes a speed dial call, it is determined whether the call is to a central office line or PBX extension 9, depending on the outside line that is captured, and if the call is to a central office line, The apparatus is equipped with a control means for transmitting the abbreviated dial data read from the memory section until the end of the call, with a PBXO office line acquisition code added in front of the abbreviated dial data in the case of a call to a PBX extension.

(Example) The present invention will be explained in more detail below with reference to one drawing.

FIG. 1 is a block diagram showing an embodiment of a key telephone device according to the present invention. This equipment fjtFi is composed of a main device 1 and a plurality of (N) button telephones 2, and the main device 1 further includes an outside line interface section 3 and a call path switching section 4 that accommodate central office lines and PBX extension lines, Telephone interface part 5, monarchy part 4 part 6, and a memo to remember the speed dial contents! JftB7 and a common bus interface 8 that connects the above-mentioned troughs.

Each part of this button telephone device operates as follows.

Type information of the tiger outside line connected to the outside line interface section 3,
That is, system data such that (]01 is a central office line and C02 is a PBX extension line is stored in the royal system section 6 via the button telephone 2.

On the other hand, the dial data of the outside line destination of each key telephone 2 is stored as abbreviated data in the memory section 7 through the telephone interface section 5 and the common bus interface 8.

When the button telephone 2 captures an outside line and makes a speed dial call, the captured outside line number (C01,002...
...OOM) information is sent to the Royal System Division 6 via the telephone interface unit 5 and the common bus interface 8, so the Royal System Division 6 recognizes from the system data that 001 is a central office line, and CO2 is a PBX extension line.

In the case of a local line, the abbreviated dial data is read from the memory section 7 and sent directly to the outside line interface section 3 via the common bus interface 8. On the other hand, PBX
In the case of an extension, the PBX central office line acquisition code ('0'' in Japan) is placed before the speed dial data read from the memory section 7.
It is sent to the external line interface unit 3 via the common bus interface 8. When the other party answers, the communication path switching section 4 is controlled, and the outside line interface section 3 and the telephone interface section 5 are all connected to form one communication path.

(Effects of the Invention) As explained above, the present invention identifies the type of connected multiple types of external lines, that is, central office lines, and BX extensions, and if it is a central office line, reads it out from the memory section and dials the speed dial. The data is sent out as is, and in the case of a PBX extension, the KPHX office line capture dial code is automatically attached before the speed dial data, so when talking to a PBX extension, %PBXO station MA capture dial code strength 0
This has the effect that operations can be omitted and the operability of the key telephone is improved.
