Abstract

PURPOSE:To easily execute operation relating to a line wire specification number by sending a line wire selection number of a PBX in stead of prescribed data prior to a following dialings only when a telephone network specification request is generated and the line wire is stored in the PBX. CONSTITUTION:In a line wire selecting state, prescribed key data is inputted as 1st dial data in an terminating number storing memory, and only when a telephone network specification request is generated and the line wire 2 is stored in the PBX 3, the line wire selection number of the PBX 3 is sent in stead of the prescribed data prior to the following dialings. Since it is unnecessary to distinguish dialing operation between the line wire 1 of the telephone network 6 and the line wire 2 through the PBX 3, the operation relating to the specification of the line wire can be easily executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button telephone exchange that mixes external lines connected directly to a telephone network and external lines connected to the above-mentioned telephone and network via a PBX.

[Prior art] Among the outside lines connected to a button' local telephone exchange, there are two types: one that connects directly to one telephone network, and the other that connects to the telephone network through a PBX. It may be used in combination with exchange equipment. In this case, when making a call to the telephone network via the PBX, an outside line designation number (a dial set to designate an outside line, generally O) must be added in front of the other party's telephone number.

[Problems to be Solved by the Invention] In the conventional device described above, when using one-touch dialing or speed dialing with a button telephone exchange that automatically selects an outside line, if an outside line via PBX is selected, the designated outside line number is selected first. If you have selected an outside line that does not go through a PBX, there is no need to press the designated outside line number.

Therefore, depending on the external line selected by automatic selection, there are cases in which the specified external line number is sent first and cases in which the specified external line number is not sent, and there is a problem that it is troublesome to perform this operation reliably. .

The present invention provides that in a button telephone exchange that mixes outside lines connected directly to the telephone network and outside lines connected to the above telephone network via PBX, no matter which outside line is selected by automatic selection, the outside line designated number The object of the present invention is to provide a button telephone exchange that is easy to operate.

[Means for Solving the Problems] The present invention provides that when an external line is selected, predetermined key data is input as first dial data in the destination number storage memory, a telephone network instruction request is made, and an external line accommodated in the PBX is input. Only in this case, the PBX's outside line selection number is sent instead of the predetermined data prior to the following dialing.

[Function] In the present invention, when an outside line is selected, predetermined key data is input as the first dial data in the destination number storage memory, and a telephone network instruction request is made, and the predetermined key data is input only when the outside line is accommodated in the PBX. Since the outside line selection number of the PBX is sent instead of data prior to the subsequent dialing, operations regarding the outside line designated number are easy no matter which outside line is selected by automatic selection.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of the present invention.

An outside line 2 of the telephone network and an outside line 2 via a PBX 3 are connected to a key telephone exchange 4. An extension telephone 5 is connected to this button telephone exchange 4. In the above embodiment, the "main key" is used as the key for instructing the PBX 3 to make a call to the telephone network.

Normally, the functions of key telephones are to select an external line by pressing the key corresponding to the external line or by performing an operation to specify a specific external line, and to dial 0 or take the handset off-hook while dialing an internal line. There are two ways to automatically select a station and make an outside line call.

For any of the above calls, to make a call to the telephone network,
If the selected outside line is the direct telephone network 1 (external line 1 of the telephone network shown in FIG. 1), the telephone number of the other party may be directly sent. Also, if the selected outside line is an outside line via a PBX (external line 2 in Figure 1), normally, in order to get out of the outside line from the PBX,
After sending O, preparations for making a call to the telephone network 6 are completed, and then all that is required is to send the other party's telephone number.

In the above embodiment, when making a call to the telephone network, as shown in FIG. 3, "tree" is inserted as the first dial data to give an instruction to make a call to the telephone network.

In addition, when the key telephone exchange a4 is in the external line selection state,
Enter the predetermined key data (main key data in the case of the above embodiment) as the first dial data, and if there is a telephone network instruction request, input the outside line selection number of the PBX to the following dial instead of the above predetermined key data. It is sent in advance.

Next, the operation of the above embodiment will be explained.

FIG. 2 is a flowchart showing the operation of check conversion of dial data in the above embodiment.

First, when dialing an outside line (Sl), the first digit is a one-touch key or speed dial (S2).
, S3), if the first dial data (first digit data) is the predetermined key data "Thu" (S4), it is determined whether or not the connection is made to an outside line via the PBX (S5).

When connected to the outside line 2 via the PBX 3, the predetermined key data "Thu" is converted to rQJ (S6), and one-touch dialing or abbreviated dialing is sent (S7).

On the other hand, if it is connected to an outside line that does not go through the PBX 3 (that is, outside the telephone network) in S5, the predetermined key data "Thursday" is ignored (S8), and one-touch dialing or speed dialing is sent (S7).

In this way, there is no need to perform separate dialing operations for the outside line 1 of the telephone network and the outside line 2 via the PBX 3, so the operation is easy.

In FIG. 2, if any of the following applies: it is not an outside line call, it is not the first dial, it is not a one-touch dial or speed dial, and the first digit is not "1", then the process proceeds to normal processing (59).

[Effects of the Invention] According to the present invention, an outside line and a PBX directly connected to a telephone network
In a button telephone exchange that mixes external lines connected to the above-mentioned telephone network via the above-mentioned telephone network, no matter which external line is selected by automatic selection, the operation regarding the designated external line number is easy.
