Description

Subscriber interface board that provides a ringtone for each subscriber.

The present invention relates to a subscriber interface board in a private branch exchange (PBX). Specifically, when a user stores several types of bell tones and the other party calls them, the telephone rings with the stored bell to work away from the telephone. Knowing who called during a call or during a conversation, particularly with a subscriber interface board that provides a subscriber-specific ringer that can be useful to secretaries who receive a lot of important calls.

The subscriber interface board of the conventional private branch exchange (PBX) does not have logic to generate a bell.

1 is a block diagram of a conventional telephone subscriber interface board.

As shown, the conventional subscriber interface board 10 is connected to a control board 1 for controlling various local boards, and has a PB interface unit 11 for performing a parallel bus interface with the control board 1. A line communication controller (LCMC) 15 for communication with the RAM 12, the CPU 13, the ROM 14, the subscriber terminal, the line coding function, the subscriber terminal impedance matching function and the power supply function, It consists of a line interface part 16 which has a shock voltage protection function, and the LED part 17 which shows the state of a subscriber.

The line interface unit 16 is equipped with a DASL (Digital Ad Apartment for Subscriber Loops) chip to interface with each subscriber station.

Looking at the operation of the conventional telephone interface configured as described above, if the switchboard is installed after mounting the control board (1) and the telephone interface board (10) that manages various local boards and the telephone (20) connected to supply power Between the telephone 20 and the subscriber interface board 10, DASL (Digital Ad Apartment for Subscriber Loops) chips exchange messages and synchronize with each other.

When synchronized, the control board 1 gives a telephone number to each telephone 20 according to the data already produced.

The digital telephone 20 used by each subscriber is provided with a flow button in addition to the dial pad. The user can register the extension or trunk line telephone number that he or she uses mainly in the floating button and use it as a shortcut.

If the other party calls itself, the subscriber interface board 10 sends a message to the telephone in the form of a message already promised through the data channel (D-CH) of the corresponding telephone number. After receiving the message, it analyzes the bell and rings the digital signal processor (DSP Chip) chip that can generate a bell.

However, in the conventional digital telephone, there is a problem in that it is monotonous and indistinguishable from the extension line and the trunk line ring because one bell rings. You can choose the type of bell on your phone, but it comes with the limitation of ringing only one type of tone. When the phone rings when the phone rings before the call is answered, there was a limit that it is impossible to know who called it. Moreover, when the call comes from an important person, the problem is even more serious.

The present invention has been made to solve the problems described above, subscribers to provide a ringtone for each subscriber to know the calling subscriber even by listening to the ringing tone by allowing the ringing party subscriber to make a different ringtone for each subscriber It is an object to provide an interface board.

A feature of the present invention for achieving the above object is in the telephone subscriber interface board, a ringing ring generating means for providing various kinds of bells, and subscriber-specific ringing ring registration information input from the terminal of the called party subscriber is stored A ringtone registered for the calling party by controlling the ringtone generation means based on the ringtone registration information storing means and the ringtone registration information stored in the ringtone registration information storing means for each subscriber when a call is received from any subscriber; And a ringing control means for selecting a bell and supplying it to the called party.

2 shows an embodiment of the present invention. As shown, a parallel bus (PB) interface unit 11 for communication with the control board 1 which transmits the main control command of the exchange, and a line communication controller (LCMC) 15 for communication with the subscriber station. In addition, the LED unit 17 for displaying the status of the subscriber terminal, the line coding function, the line interface unit 16 for the subscriber terminal impedance matching function, the power supply function, the shock voltage protection function, and the program to be performed for the subscriber interface A built-in ROM 14, a RAM 12 storing subscriber ring data for each subscriber input from the subscriber terminal, a ringtone generator 19 storing various ring tone tones, and a call from any subscriber Access the RAM 12 to retrieve the ringing registration information for the calling party subscriber, and based on the program stored in the ROM 14, the interface between each subscriber station CPU 13 for performing the calculation and the ringer generation unit 19 on the basis of the ring registration information for the calling party subscriber transmitted from the CPU 13 to control the ring registered for the calling party subscriber. And a ringing bell controller 18 to select and supply the subscriber.

The operation of the subscriber interface board according to the present invention is controlled by the control board 1 which transmits a switch control command.

When the control board 1 and subscriber interface board 10 are mounted in the exchanger and the power is supplied after the telephone is connected, the DASL between the subscriber telephone 20 and the subscriber interface board 10 is connected. (Digital Ad Apartment for Subscriber LOOPS) Chips exchange messages and synchronize with each other.

In synchronization, the control board 1 assigns a telephone number to each telephone in accordance with already produced data.

Looking at the operation of providing a different ringer for each subscriber in the subscriber interface board 10 according to the present invention configured as described above are as follows.

Each subscriber can register the subscriber's phone number of the extension or trunk line as a shortcut when there are frequently dialed phone numbers on the floating button provided in the subscriber terminal. You can program your call to ring when a call comes in. That is, the ring tone of the ringing bell can be specified differently in response to the extension bell, the trunk bell, and the important subscriber of the extension. In this way, the ring data for each subscriber assigned to each floating button is stored in the RAM 12 as a database DB. That is, the subscriber's ringtone registration information, which is input to be registered and can be modified by the operation of a flow button and a dial pad, provided in the subscriber's digital telephone of the subscriber's ringtone registration information storage device, is stored.

In addition, when the subscriber ring registration information for each subscriber is stored in the RAM 12, it will be more desirable to store the ringtone registration information for each called party subscriber phone in the interface for each called party subscriber.

It is configured to be powered by a backup battery (emergency power source) for safe storage of the database, so that incoming ring information for each subscriber stored in the RAM 12 is always maintained even when an abnormality occurs in the power supply unit (POWER OFF, etc.). do.

The subscriber can designate the subscriber's number to be registered in the flow button provided in his terminal and operate the dial pad to select and program a desired ring tone from a ring type provided from the ring tone generator 19. have. The ring tone generator 19 stores ring data that can be selected by the subscriber. The ringing tone generator 19 stores digital ringing tone information to provide various ringing tone.

The bell data provided from the ringing tone generator 19 is transmitted to the subscriber station 20 under the control of the ringing tone control unit 18. The ringer control unit 19 can be largely controlled to select a ringer for each extension subscriber and CO line subscriber.

One subscriber interface board 10 is provided with two LCMCs 15, each LCMC 15 having eight line interface portions 16, and each line interface portion 16 one each. Is connected to the subscriber terminal. Therefore, the number of subscribers accommodated in one subscriber interface board is 16 subscribers, and the number of subscribers can be increased by increasing the capacity. If one of the 16 subscribers contained in the subscriber interface board is called, the CPU 13 transmits a message indicating that there is a call from the outside to the terminal of the called subscriber. Before sending the message, the CPU 13 searches for a ringtone data base set by the called subscriber in the RAM database, and whether a specific ringtone tone is registered for the calling party subscriber. Search for.

If a specific ring tone is registered, the signal (voice) is put on the voice channel (B-CH), and the telephone rings the registered ring tone through the speaker.

If a specific ring tone is designated for the calling party subscriber who has made a call, the ring tone controller 18 informs the ring tone information of the designated ring. The bell controller 18 controls the called bell generator 19 to send corresponding bell information on a voice channel (B-CH) for transmitting to the called subscriber. The terminal of the called party receiving the call receives the bell information transmitted by the control of the called bell controller 18 and generates the called bell based on the bell information. If there is no specific ringing for the calling party's telephone number, the default ringing tone will ring through the speaker. The subscriber station generates a call ring corresponding to the registered subscriber, and at the same time, the telephone number of the calling party subscriber is displayed in the case of an extension line and "LINE RINGING" is displayed in case of a trunk line. Therefore, the subscriber can check the incoming call ringer from a distance, even if the call from the subscriber set to the floating button provided in his terminal to hear the incoming call ringing from afar.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and it is common knowledge in the technical field to which the present invention pertains that various substitutions, conversions, and changes can be made without departing from the technical idea of the present invention. It will be apparent to those who have

According to the present invention, since the bell sound of the same tone is heard regardless of the extension, the trunk line, etc., the problem of not knowing who is calling is not solved by looking at the LCD.

When you use the public, if you register a frequently used phone number, even if the bell rings and disconnects, you can listen to the ring tone and know who the call is coming from, so you can make a phone call. By registering and using the ring tone on the line differently, it provides a convenient effect for the secretary to work from a distance away from the phone or to know who was calling just by the tone of the bell during a conversation.
