Description

Switching apparatus using the IP phone combined PSTN phone}

According to the present invention, since a conventional telephone and related telephone system can be used as it is, an Internet telephone can be easily used anywhere regardless of a place as long as there is an internet dedicated line and a telephone line, and an expensive internet dedicated telephone, a gateway, a computer, etc. In the absence of an environment, the existing telephones and telephone lines can be used as it is, so there is no need to purchase additional telephones and Internet phones, thereby creating an integrated environment that can significantly lower infrastructure costs. It is possible to use conventional telephones and personal terminals, and users can arbitrarily select Internet telephone service, which can significantly lower the telephone fee and add new internet telephone service as needed. It is a technology related to a switching device that can be used as a dual.

1 is a block diagram of an analog telephone generally used in a PSTN.

Referring to FIG. 1, a PSTN connector 111 connected to an exchanger, a bridge circuit 112 for switching polarity of a ring and a tip, and a hook for detecting a hook on / off and forming a loop upon hook off A sensing and loop forming unit 113, a handset unit 114 for a call, a buzzer 115 for generating a buzzer sound, and a controller for setting a transmission / reception path and generating a ring according to the hook on / off state ( 116, a keypad 117 for directly inputting a desired number by the user, and a clock generator 118 for generating a clock.

The conventional PSTN analog phone as described above will be described with reference to FIG. 1.

First, when a signal is generated from the exchange, it is received by the PSTN connector 111, and the received signal is transmitted to the hook detection and loop forming unit 113 through the bridge circuit 112. The hook detection and loop forming unit 113 detects the received signal and transmits the received signal to the control unit 116. Then, the controller 116 generates a ring through the buzzer 115 and outputs it to the outside, and the user hears the ring sound and off-hooks the handset of the handset 114. At this time, the hook detection and loop forming unit 113 detects the off-hook and forms a loop, and can make a voice call with the calling party through the control unit 116.

On the contrary, when the user off-hooks the handset of the handset 114, the hook detection and loop forming unit 113 detects the off hook and forms a loop. At this time, the control unit 116 detects a loop, transmits a dial tone to the user, and waits for input of the keypad 117. When the user inputs a desired phone number from the keypad 117, the keypad 117 scans the corresponding key and transfers the number to the controller 116. The controller 116 detects a hook by detecting a DTMF tone. And the loop forming unit 113, the bridge circuit 112, and the PSTN connector 111. At this time, the exchange generates a ring back tone while detecting the corresponding telephone number and transmitting it to the called party, and the ring back tone is transmitted to the handset 114 through the control unit 116. When off-hook is made at the called party, the voice call is connected to allow the caller to talk to the called party.

However, conventionally, the PSTN telephone does not have an Internet telephone function and thus cannot make an Internet telephone call. The Internet telephone also does not have a PSTN telephone function, and thus, each individual terminal uses a PSTN or IP telephone service.
