A control unit that performs control of the control data line 114 and control of the control data line 114 with the key telephone, while performing control of the control unit 15 and other functions of the DSS console device. Next, the key telephone 120 will be described. In FIG. 1, reference numeral 121 denotes a data communication unit; 123, a control unit of the key telephone 120; 122, a communication circuit unit; and 124, a modular jack unit. The data communication section 121 is connected to a data communication terminal of the modular jack section 124, while the communication circuit section 122 is connected to an audio terminal of the modular jack section 124. The audio terminal of modular jack 124 is DSS by 4-wire cable
Since it is connected to the audio terminal of the modular jack unit 112 in the console device 110, the communication circuit unit 122 is directly connected to the main device 100 via the audio line 113 in the DSS console device 110. Next, examples will be described. FIG. 4 shows a control procedure of the data communication unit of the main unit 100. FIG. 5 shows a control unit 117 of the DSS console unit 110.
This is the data communication procedure. The data communication is started when the main device 100 has started first. In FIG. 4, when the need for data communication arises, the communication partner at that time is identified as a DSS console device or a key telephone (401), and then an identification header is transmitted in each case (402). The switch unit 115 is always a data communication unit
Since the communication is set between the main device 100 and the communication device 116, the identification header transmitted from the main device 100 is received by the data communication unit 116, and the control unit 117 receives the identification header. Generate an interrupt. The reception interruption process, that is, the process shown in FIG. 5 is started. In FIG. 5, when the identification header is received (50
1) Based on the content of the identification header, it is determined whether the communication partner is itself or a key telephone (502). If the communication partner is itself, it enters the data reception mode as it is, and receives transmission data (hereinafter abbreviated as downlink data) from main device 100 (503). Then, after receiving the downlink data, it transmits the data to the main device 100 (hereinafter abbreviated as uplink data) (504). FIG. 2 shows the timing of a series of data transmission / reception when the communication partner is itself. That is, after receiving the downlink data from the main device 100, it transmits the uplink data to the main device 100. At that time, the switch unit remains down to the DSS console device 110 side. Of course, there is no transmission of data from the key telephone 120. In FIG. 4, the main unit 100 transmits and receives data (4
(03, 404) ends normally, and if there is no abnormality in the uplink data (405), a communication completion signal is transmitted, and the communication processing ends (406). On the other hand, in the DSS console device 110, as shown in FIG. 5, when the control section 117 receives the communication completion signal, it performs processing of the received data, temporarily ends this processing, and has the next reception interrupt (505). , 506). By the way, when the identification header indicates a key telephone, as shown in FIG.
Is switched to the modular jack section 112, the time required for the key telephone 120 to perform normal communication is set in the timer (508), and the process is terminated (509). The control unit 123 of the key telephone performs data communication with the main device 100 according to the control procedure in the DSS console device 110, that is, the same procedure as (503) to (507). On the other hand, the control unit 117 of the DSS console device switches the switch unit 115 by an interrupt generated due to the timeout of the timer, and returns to the normal state. As described above, in the present embodiment, the communication is started by the polling operation from the main device 100, and the control unit 117 of the DSS console device analyzes and determines the communication partner independently. Advantageous Effects of the Invention The present invention provides a switch unit for switching a communication line from a main unit to a data communication unit or a telephone and connecting the switch unit and a switch unit in response to an identification signal sent from the main unit via the communication line. since there is provided a control unit for switching control, the main device, if you want to send a data signal to one of the hotel phones to DSS console device or DSS console device, to advance either device wants to send data signals By transmitting an identification signal indicating that the data signal is transmitted through a communication line for transmitting a data signal, the data signal can be transmitted from the main device to a desired device through a pair of communication lines, and the DSS console device and the telephone can be connected. Communication lines can be shared. For this reason, a single communication line can be used together with the telephone without reducing the number of telephones, and even when the telephone is installed or relocated, a new communication line is added only for the DSS console device. This eliminates the need for construction work for adding a DSS console device. Also,
Since a pair of communication lines are shared by the DSS console device and the telephone, the number of communication lines of the main device is not reduced. Furthermore, whether the communication line is connected to the DSS console device or connected to the telephone is determined entirely in the DSS console device, and the attached telephone may not have a special configuration having a telephone, Even if a DSS console device is used together with a communication line using only a telephone, there is no need to purchase a new dedicated telephone or add any device to the telephone. In addition, the construction does not require much work, and the cost increase for installing the DSS console device can be minimized, so that the practical effect is great.
