In addition, the function key FUK of the keyboard KB
These include a number of station line buttons corresponding to the number of station lines accommodated in the main unit KSU, a single hold button for placing the station line on hold, a single monitor button for monitoring with the speaker SP and rejecting extension calls, and a redial button. Single recall button used for.

A single transfer button for transfer after holding a central office line, a single extension button for internal calls, etc. are provided, and correspondingly, an indicator light of a display circuit LDP is provided for each of these, and a display circuit LDP is installed in advance. There are multiple auto-dial buttons that automatically dial registered numbers.

Figure 2 is a comprehensive flowchart of the control situation by the processor in the control unit CNT.
Set the initial state according to "TART"! After performing initialization, receive one control data from the main unit KSU.
Then, the operation data is sent once to the main unit KSU, the operation status of each part is detected by the l key detection, and the 1 key processing described later is performed, and then the data is sent to the receiver. In response to the received control data, control signals are sent to each part to control the lighting and dimming of indicator lights and the sending of tone signals. is to be repeated.

Note that each of the above steps is performed while accessing the necessary data to the memory.

FIG. 3 is a 70-chart showing the details of the key processing, in which the operation data is stored in the 1-transmission buffer memory using a part of the memory, and the operated one is the 1-dial key? If this is YES, similarly determine N on-hook, and assuming this is YES, a part of the memory is used and there is no data in the N dial memory?
〃 If this is YES, the number of the operated dial key PDK is "1 dial rx"? After determining I/, if it is YES'''C, store ``Yin'' in the Qi dial memory.

By the way, the Ki dial key? ", 5 on hook?" and 1
Dial [XJ? If the answer is No, ki dial memory clear is performed.

Therefore, rxS o
, o, 0" are predetermined, and when these are sequentially input using the dial key PDK in the on-hook state, "x" is stored in the dial memory at the above-mentioned period.

Then, in the second cycle, ■Dial key?
“and” on the hook? No data in 1 dial memory via YES? 〃 becomes No, and the number of the operated dial key PDK is N dial “0”? If the judgment is YES, ■Dial memory td
fxJ? 〃Nyo! >rxj is stored or not, and in response to YES, "0" is stored in the key dial memory.

In addition, Ki Dial 1-OJ? If ' is No, the process moves to A-dial memory clear.

Therefore, by dial key PDK, br*.

0.0.0" is operated, "x, 0" is stored in the dial memory in the second cycle.

Is r*J? ' is NO, the key dial memory is '■,
0”? A determination is made, and in response to YES, "10" is stored in the dial memory again.

Therefore, "x10, O" is stored in the dial memory.

In the fourth cycle, the Qi dial key? 〃's YE
S to 1 dial memory is rxJ? Through rt's NO, the N dial memory is now "xlo"? 〃 is No
In response to this, ■ Storing the circle in the dial memory is performed, and the contents of the dial memory become "x10.0.0".
In accordance with this, we move on to the ``test mode processing'' described next.

FIG. 4 is a flowchart showing the details of the test mode processing. When the test mode information is stored in the memory by ``store test mode in memory'' and the test mode is set, the data with the main device KS [J] is stored. Signal transmission and reception are stopped, and the connection with the main unit KSU is apparently disconnected.

In this state, the dial key PDK is operated. If 〃 becomes YES, the operated number becomes N.
Dial “+”? 〃, and if this is No, ``1'' to ``9'', or ``0'', a ``tone signal transmission'' corresponding to this number is performed, and the speaker SP as an audible display means sounds, 9 on futsuku? While 〃 is YES, the above operation is repeated.

Also, if a key other than the dial key PDK is operated,
1 dial key? 〃No through N other keys? 〃 becomes YES, and depending on the operated key, the indicator light as a visual display means (lit/flashing) disappears, and 1-on hook? This operation is repeated while 〃 is YES.

In addition, ′ dial “≠”? “ If YES, then
1 indicator light, tone signal/reset〃, lean signal is sent〃, and light indicator light/lighting/blinking status is stopped.

Therefore, by operating the dial key PDK and the function key F [JK, it is possible to freely cause each display means to perform various display operations according to predetermined numbers and types, and to perform various display operations for calls and main unit KSU. It is possible to locally test each function of the telephone ST itself, except for data signal transmission and reception.

In addition to this, if you do an off-hook, can you get one on-hook? 〃 becomes NO, the indicator light, tone signal, and reset are performed, and the memory is cleared in the N test mode, so the test mode setting is canceled and the normal operating state is restored.

FIG. 5 is a block diagram showing the basic configuration of the present invention,
Control unit CNTs and corresponding detection unit DKD and judgment unit JLI
D and control unit CT are provided, and a hook switch H8
The output of 2 and the output of the dial key PDK are the detection unit DK.
The detection unit DK detects how the dial key PDK comes out assuming that it is in an on-hook state.
D detects it, and the judgment unit JUD judges the output of the dial key PDK according to the detection force, and if it judges it to be data indicating a test request, it gives this judgment result to the control unit CT and operates it. It is supposed to be in a state.

Therefore, when the control unit CT is in the operating state, each key P
According to the outputs of DK and FUK, the control unit CT turns on the oscillator O.
SC and the switch circuit sw2 are controlled to cause the speaker sp to sound via the amplifier A with a tone signal from the oscillator OSC, while controlling the indicator lights of the display circuit LDP to cause them to turn on or blink.

However, the configuration in Figure 1 can be arbitrarily selected depending on the conditions, and in Figures 2 to 4, steps can be replaced or unnecessary steps can be omitted depending on the situation. Various modifications are possible.

[Effects of the Invention] As is clear from the above explanation, according to the present invention, the system test mode can be set only by operating the dial keys, without operating the extension number setting switch, etc. Since tests can be performed freely, test operations are easy, there is no risk of making mistakes in setting extension numbers, and remarkable effects can be obtained in various key telephones.
