The customer management system according to the present invention includes a CLID terminal 100 connected to a PSTN of a telephone operator providing a Calling Line Identification (CLID) service, a telephone 30 connected to the PSTN through the terminal, and a terminal. It consists of a small printer 40 and a personal computer 50 connected to the communication port of 100.

The CLID terminal 100 includes an LCD display 10 installed in the main body, direction keys 12 such as up / down keys, operation mode selection keys 14 such as a delete button, a dialing button, a menu selection button, It is provided with a keyboard 20 to enter the name and address of the caller and the transaction details.

Customer management system using the CLID as described above, in addition to the caller's telephone number provided by the CLID, the caller's name and address and transaction details, etc. By additionally registering the board to be displayed later on the monitor of the LCD display 10 or PC 50 when a call is made, it is possible to output the displayed information through the printer 40 if necessary.

The configuration of the CLID terminal 100 is shown in detail in FIG.

CLID terminal 100 according to the present invention is a CLID chip (2) for demodulating the telephone number data of the caller input through the trunk line, and a central processing unit for receiving the demodulated caller telephone number data and controlling the system according to a user command (1), a memory (EEPROM) 5 for storing telephone number data input to the central processing unit and storing customer information data input by a user search, and a dialing operation corresponding to the telephone number stored in the memory 5; DTMF generator (3) and DTMF driver (4) for performing the operation, off-hook detector (6) for detecting the off-hook state of the separate telephone connected to the trunk line and transmitting it to the central processing unit (1), and a small printer And a RS232C port 8 for serial data communication with an external device such as a PC, and a keyboard controller 7 for transmitting a key signal input from the keyboard 20 to the central processing unit.

The CLID chip 2 is a commercially available CLID terminal IC. When a ring signal is input through a trunk line, the central processing unit 1 demodulates the FSK asynchronous data specified in Bell 202 or CCITT V.23. Perform the function of sending to. The CLID IC 2 may have a complex chip form integrating an LCD driving IC and a caller identification chip. In addition, the DTMF generator 3 and the DTMF driver 4 also use commercially available ICs for dial-signal generation of electronic telephones.

In the present embodiment, the central processing unit 1 has a caller's telephone number confirmation and an LCD driving function, and stores a program for building a customer database according to the present invention. Therefore, the central processing unit 1 stores the telephone number data received from the CLID IC 2 in the memory 5 and displays it on the LCD display 10.

The memory 7 stores telephone number data supplied from the CLID IC 2 to the CPU 1 and stores customer information data input through the keyboard 20. A conventional EEPROM or flash memory device is provided. Use

The telephone number stored in the memory 5 can be dialed through the DTMF generator 3 and the DTMF driver 4, and the off-hook detector 6 detects the telephone use and centrally processes the telephone when the telephone is connected to the trunk line. A signal is sent to the device 1, whereby the central processing unit 1 generates a control signal that cuts off the line between the CLID IC 2 and the trunk line.

In this embodiment, the keyboard 20 includes a Korean consonant, a vowel, a number, a special key, and a print key for inputting a sender's name and address and transaction details.

The main control operation performed by the CPU 1 in the CLID terminal as described above will be described with reference to the flowchart of FIG. 3.

In step 10, if a ring signal is input to the terminal via the trunk line, it is determined whether a ring signal is detected, and the flow goes to step 12 to determine whether caller telephone number data has been detected in the CLID IC 2. If the phone number data is detected, go to step 14 to store the entered phone number data in the memory 5 and drive the LCD display 10 in step 16 to display the entered phone number with the current time.

Accordingly, the user checks the telephone number displayed on the display 10 and picks up the handset of the telephone 30 to make a call.

On the other hand, when the ring signal is not detected in step 10, go to step 11 to wait for the user's telephone number search mode. When the user presses the telephone number search button, it is determined whether the customer information input menu is selected in step 13, and if the information input menu is selected, the procedure proceeds to step 15 in which the caller telephone number database stored in the memory of the central processing unit 1 is stored. Run the program. The database program can be displayed on the LCD display 10 or via the monitor of the user PC via the serial port 8.
