Description

[Detailed description of the invention]

[Industrial Application Field] The present invention registers operation data regulating the operation state, and also registers operation data that regulates the operation state and uses a direct selection device (Direct
This invention relates to a method for setting a registration mode in which operational data is registered in a key telephone device equipped with a connection means for a Station Selection Console (Station Selection Console). [Prior Art] Generally, in a key telephone device, operation data such as call restriction status, speed dial number, etc. is stored in a memory, and the contents of this memory are referred to during operation to make decisions regarding exchange connection control. In order to store and register such operational data in memory, a registration mode must be set by button operation on a specific button telephone, and then various operational data must be registered by operating dial buttons, etc. It is becoming. However, in order to prevent the risk of entering registration mode due to unconscious button operation and further updating the operational data, a separate connector or terminal dedicated to registering operational data must be provided, or
As disclosed in Japanese Patent No. 90893, the main device is provided with a switch for switching to the registration mode. On the other hand, as the number of lines accommodated increases, it becomes necessary to smoothly transfer incoming calls from outside lines or to make calls to all key telephones all at once. A direct selection device is prepared, which is connected to the main device and is used by semi-full-time switchboard operators together with an attached key telephone. [Problems to be solved by the invention] However, if a connector or terminal for registration is provided, the number of parts increases, the circuit configuration becomes complicated, and the cost becomes high. In addition to the increase in the number of parts, it is necessary to go to the main device before starting the registration operation, which creates a troublesome problem. [Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention is constituted by the following means. That is, in the above-mentioned button telephone device, the button telephone is connected to the connection means to which the direct selection device is connected, button operation information of this button telephone is provided, and periodic data transmission via the connection means is abnormal for a certain period of time or more. It is assumed that the first normal data given after the initial data is data specific to the key telephone set, and the registration mode is set in connection with this detection. [Operation] Therefore, once the connection means such as the connector or terminal to which the direct selection device (hereinafter referred to as DSS) is connected is
If you remove DSS and connect a key phone instead, the data transmission interruption during this period will become a data transmission abnormality for a certain period of time, and the registration mode will be set according to the next normal data from the button phone. . [Example] Hereinafter, details of the present invention will be explained with reference to figures showing examples.

FIG. 4 is a plan view of the DSS 5, and the panel surface includes self-illuminated keys corresponding to each ST4 ₁ to 4m and keys 57 ₁ to 57 _P , which are similar keys for individual calling, group calling, all calls, etc. , and lamps 56 ₁ to 56 _P are built inside the key. As each key is operated, operation data is transmitted and control data is received, and the indicator light for each key is turned on, off, or blinking depending on the control data, and a semi-full-time operator is in charge. For example, the ST4m is used as an attached telephone to transfer incoming calls after they are put on hold, and to make group calls as necessary. Figure 4 is a plan view of the DSS5, and keys ₅₇₁ to _57P , which are the numbers ST41 _to 4m plus function keys such as a simultaneous call key, are arranged on the panel surface, and the keys are self-illuminated. The lamps 56 ₁ to 56 _P are built inside. The DSS configured in this way also has KSU1
Data transmission between ST4 ₁ to ST4 4m and DSS5 is carried out sequentially and repeatedly at a cycle of, for example, 40 ms under the initiative of KSU1, and operation data is transmitted as a reaction signal in response to the transmission of control data. In particular, when no operation is performed, operation data indicating no operation is transmitted. This operation data is composed of, for example, 8 bits as follows. That is, it consists of 8 bits consisting of the upper 4 bits b4 to b7 shown by symbol A in FIG. 5 and the lower 4 bits b0 to b3 shown by symbol B. The most significant bit b7 indicates the state of the switch Subsequent bits b0 to b
The state of each button is indicated by 6, and if the button is on-hook, bit b7 has a logical value of "1", and if it is off-hook, it is "0". This hook code repeatedly transmits the hook state, and the key code represented by bits b0 to b6 is transmitted only once.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the registration mode is automatically set by a simple operation of connecting the ST to the DSS connection means.
No additional parts or circuits are required, the configuration can be made at low cost, and unconscious setting of the registration mode is reliably prevented, resulting in remarkable effects in various key telephone devices that require the registration of operational data.
