6, network function of the present utility model mainly contains:

(1) network ID authentication: when carrying out network operation, the prompting client inputs password, and system connects with distance host automatically and sends authentication information, and main frame judges according to telephone number, customer information and password whether it is validated user and return authentication result.

(2) manual transmission information: after finishing [business information typing], select sending function by keyboard, governor circuit passes through the Modem circuit immediately to remote terminal dial-up, after setting up the telecommunication network connection, the business information that governor circuit will need to send again is organized into packet, send the far-end computer main frame to, detect data simultaneously and whether successfully send.

(3) automatic reception information: the far-end computer main frame can the terminal to being dispersed in everywhere initiatively send specific business information, as notice, prompting, inquiry and warning message etc.The data that governor circuit is distinguished automatically and automatic reception far-end computer main frame sends are stored in the memory of governor circuit.The client can browse and reply the information of receiving at any time.

(4) network information prompting: the network information to untreated automatic reception is pointed out in the mode of sound or signal lamp flicker.

(5) network information is browsed: after the client selects querying command by keyboard, governor circuit passes through the Modem circuit to remote terminal dial-up, after setting up the telecommunication network connection, governor circuit sends querying command to the far-end computer main frame, after waiting for the far-end computer host process then, the reception Query Result also is presented on the display screen of terminal.
