びソフトウェアが複雑になる欠点があった。Conventionally, in order to perform data communication using telephone lines, there is a network control device that performs outgoing calls, nine incoming calls, etc. to nine lines, and a network control device that is indirectly connected to the line through this network control device and transmits data signals and voice frequencies. A separate interface unit is installed between the communication control device that controls these network control devices and modems, and the network control device and modem, and performs network control and data communication of telephone lines. It was common to do so. Therefore, the interface with the 9 communication control device requires two cables, which has the drawback of complicating the hardware and software.
本発明の目的は２通信制御装置と網制御装置及びモデム

御部とから構成されたモデム刺網制御装置が得られる。According to the present invention, there is provided a network control device with a modem, which is installed between a telephone line and a communication control device, etc., and performs network control operations and data transmission/reception based on control signals from the communication control device, etc. one of a connected network control device, a modem connected to this network control device, and the communication control device;
A modem gill net control device is obtained which is constituted of the network control device and a control section that controls the modem in response to signals.
本発明者らは、網制御動作とデータ通信動作が同時に動
作を行なう事が無いことに着目した。The inventors of the present invention have focused on the fact that network control operations and data communication operations are never performed simultaneously.
従って、上記の如くにインクフェース部を共用にして切
替え使用としても何ら問題は生じない。Therefore, no problem occurs even if the ink face portion is shared and switched for use as described above.
次に１本発明の実施例について図面を参照して説明する
。Next, an embodiment of the present invention will be described with reference to the drawings.

ースと同様で□ある。A network control device 10 with a modem includes a network control device 2 connected to a telephone line 1, and a modem 6 or 9 connected to the network control device 2.
The control unit B is configured to control the network control device 2 and the modem 6 based on control signals from the ink communication control device 4 to and from the communication control device 4. The interface unit 5 with the communication control device 4 is electrically similar to a general modem interface.
次に第１図を参照して動作について説明する。Next, the operation will be explained with reference to FIG.

の捷ま送出される。Normally 2 When the communication control device 4 sets the interface signal 7 to 9, for example, the DTR signal, to a low level, the control unit 6 does not transmit the signal (code information) on the transmission data line transmitted from the communication control device 4 to the modem 6. . The control unit 6 treats the low level signal of the DTR signal as a control signal for network control etc. 9 For example, performs automatic dialing etc. and sends information on the result of the caller's response etc. as information coated on the received data line of the interface signal 7. It is sent to the communication control device 4. The communication control device 4 performs DTR based on information such as the other party's response.
When the signal is set to a high level, the control section 6 transmits the data on the transmission data line to the modem 6 as is, thereby transmitting it to the telephone line 1. Similarly, the demodulated data received via the telephone line 1 is sent out on the received data line on the interface signal 7.

を提供できる効果がある。As explained above, the present invention is configured so that network control operations and modulation/demodulation operations can be performed with one interface section, thereby providing an economical modem that requires only one interface section and does not require cables, connectors, or circuits. This has the effect of providing an attached network control device.
