The control becomes complicated because it has to be controlled in pairs, and when installing the button telephone equipment, in addition to the cable CA for the button telephone equipment, the wiring cable CBi for the DSS stand must also be pulled out from the main equipment KSU. This method has various drawbacks, such as requiring more wiring equipment (wiring cables) and requiring more man-hours for installation.

The present invention has been made to solve the above-mentioned drawbacks of the conventional art. Therefore, in the present invention, a switch means is provided on the control data signal line, especially the signal line in the direction toward the main unit KSU, and the D
By switching and controlling the control data signal line from the SS stand DSS to the main unit KSU and the control data signal line from the button telephone ST to the main unit KSU, the DSS stand DSS and the button/telephone are connected as shown in Fig. 2. ST is connected in series with the wiring cable CA2, and can be housed in the main unit KSU using the wiring cable CAL.

Hereinafter, the present invention will be explained in detail with reference to FIG.

FIG. 3 is a block diagram of an embodiment of the present invention, showing the control data transmission portion according to the present invention.

In Figure 3, KSU is the main unit, DSS is the DSS unit, S
T is a button telephone.

In the DSS DSS, 1 is a transmitter that transmits control data to the main unit KSU, and 2 is a transmitter that transmits control data to the main unit KS.
3 is a transmitting unit that sends control data to the button telephone ST; 4 is a receiving unit that receives control data from the button telephone; 5 is a switch unit that switches the control data signal line; 6 is a called unit; This is a main body that includes a selection switch of a button telephone, a busy display light emitting element, and related control circuits.

In the button telephone ST, 11 and 13 are transmitting units that transmit control data to the DSS unit, 12 is a receiving unit that receives control data from the ftDSS unit DSS, and 14 is a control unit.

button telephone selection data (hereinafter 8 is referred to as selection data), various key data sent from the button telephone ST to the main unit KSU (data sent by key operation such as dialing information, call line selection information, etc.; hereinafter referred to as (hereinafter referred to as "off-hook data"), data sent by the activation operation (for example, disconnecting the handset) of the button telephone ST (hereinafter referred to as "off-hook data"), and data for visually displaying various statuses on the DSS stand DSS and the key telephone. data (hereinafter referred to as lamp data), etc.

ST selection data is generated by pressing a pushbutton switch provided in the main unit 6 of the DSS stand DSS, and is sent to the main device KS via the switch unit 5 and the transmitter 1.
Sent to U.

Key data is generated by pressing the dial button, call line selection button, etc. r on the button telephone ST, and includes the transmitting section 11, the receiving section 4 of the DSS stand, the switching section 5, and the transmitting section 1.
The data is then sent to the main unit KSU.

The off-switch data is generated by, for example, disconnecting the handset from the key telephone ST, and is sent to the main unit 6 of the DSS stand DSS.

The lamp data is generated by monitoring the current status of each button telephone ST in the main unit KSU, and the busy display data of each button telephone ST is generated by the receiving section of the DSS stand DSS.
The busy display data of the call line, the hold display data of the call line, etc. are sent to the main unit 6 via the receiver 2 and transmitter 3 of the DSS stand DSS and the receiver 12 of the key telephone ST.
The data is sent to the control unit 14 via the following.

The lamp data signal lines are connected in duplicate like Sl and S2, and the lamp data is sent from the main unit KSU to the DSS.
Since the data is input in parallel to the DSS unit DSS and the key telephone ST, unnecessary lamp data (L) is input to the DSS unit DSS and the key telephone ST. In contrast, the DSS unit (DSS unique lamp data) will be input.0 These unnecessary lamp data will be input to the DSS unit D.
It is not accepted by SS and key telephone ST and becomes invalid.

In other words, data is generated in one place (main unit KSU)
If there are multiple data acceptance locations (each DSS stand, DSS, and each pushbutton telephone fisT), the data acceptance side selects and accepts only the data it needs.

However, when the data is generated at multiple locations (each DSS unit and each key telephone ST) and the data is received at one location (main unit KSU), such as the ST selection data and key data, the signal line is If the devices are connected in multiple ways, data will arrive randomly from multiple locations on the data receiving side (main unit KSU), which is inconvenient. Therefore, in the present invention, a switch section 5 is provided to control all switching between the signal line S3 from the main body section 6 of the DSS stand DSS and the signal line S4 from the control section 14 of the button telephone ST, and the signal line S5 to the main device 8U. The DSS stand is configured to be activated on the condition that it receives off-hook data sent from the transmitter 13 of the key telephone ST. In other words, when the called party's key telephone ST is called by the L)SS stand DSS, the calling party's key telephone ST (
DSS unit
This prevents unnecessary calls by SS.

The signal line C1 connecting the main unit KSU and the DSS stand DSS corresponds to a pair of cables in the wiring cable CAI (see Figure 2), and the signal lines C2 and C3 connecting the DSS stand DSS and the button telephone ST are wiring lines. This corresponds to two pairs of cables in cable CA2 (see FIG. 2). However, the off-hook data transmission signal line C3 uses a speaker receiving line in the embodiment, and the two lines of the speaker receiving line are configured as a balanced transmission line for the off-hook data to transmit the off-hook data. Therefore, the number of wiring cables CA2 does not increase compared to the conventional wiring cable CA shown in FIG. 1.

For example, when making a call using the button telephone ST, the switch section 5 is in the state shown and the signal lines S4-85 are connected, and the key data sent from the control section 14 of the button telephone ST is The signal is input to the main unit KSU via the route .

In addition, when making a call operation on the DSS stand DSS, first, for example, when the handset is removed from the key telephone ST, off-hook data is sent from the control unit 14 to the DSS stand DSS via the transmitting unit 13.
The information is input to the main body 6 of the DSS stand DSS, and the DSS becomes ready for operation. When the call button switch on the DSS stand is pressed in this state, a switching command is manually sent to the switch unit 5 (signal line S6), and the switch unit 5 switches from the state shown in the figure. is connected to the main body 6
The st selection data sent from is input to the main unit KSU via the path.

The lamp data is routed from the main unit KSU to the main unit 6 of the DSS stand and the button telephone S.
The information is constantly input to the control unit of the T, and the status at that time is visually displayed for each.

As explained above, the present invention provides a switch section so that the signal line for control data input to the main device can be switched to DS.
Switching control is performed between the S unit and the button telephone, and by implementing the present invention, the DSS unit and the button telephone can be connected in series and housed in the main device, so the button '
Installation work for telephone equipment is easy and low cost,
Furthermore, it is extremely easy to change the system by adding or removing a DSS unit from a key telephone device that is already in operation.

Furthermore, the present invention has many advantages, such as the fact that the control data sent from the key telephone to the DSS unit is transmitted without going through the main device, making it easier to control the system, and its effects are extremely significant.
