Abstract
The invention relates to a router, which comprises an external exchange user interface, an external exchange station interface, a relay, a detection circuit and a control circuit, wherein the relay is electrically connected between the external exchange user interface and the external exchange station interface, the external exchange user interface is connected to a telephone, and the external exchange station interface is connected to a public exchange telephone network path. When the power of the router is switched off, the detection circuit is used for detecting whether the external exchange user interface and the telephone are in a communicated state or not. The control circuit controls the switching state of the relay according to the detection results of the detection circuit and the electrification state of the router. When an external exchange user and the telephone are in a communicated state, the control circuit controls the relay to maintain the closed state. The invention also relates to a method for the router to control the conversation connection. The router has the advantage that users can be prevented from the interruption during the public switched telephone network (PSTN) telephone dialing through foreign exchange office (FXO) interfaces.
Description
Technical field
The present invention relates to a kind of router, relate in particular to the method that a kind of router control conversation connects.
Background technology
Along with development of Internet and universal, (Voice over InternetProtocol, VOIP) technology is to be widely used for internet voice protocol.VOIP is a kind of technological service that transmits speech by IP network, and the user can utilize the VOIP device to call through the internet.
Existing VOIP device comprises router and telephone set at least; Said router comprises that relay, the outside that is connected to said relay respectively exchange subscriber (Foreign eXchangeSubscriber or Foreign eXchange Station; FXS) interface and FXS (Foreign eXchange Office, FXO) interface.Said telephone set is connected to said FXS interface, and dials the VOIP phone through said FXS; Said FXO interface be connected to PSTN (Public Switched Telephone Network, PSTN).When said router cut off the power supply, said relay can automatically switch said FXS interface and said FXO interface are interconnected, and this moment, said telephone set can be dialed pstn telephone through said FXO interface.
But; When rebuliding, the internet connects or router when re-powering; The system power supply of said router is that said relay provides the roughly power supply of 3.3V; The said FXS interface of said relay meeting automatic disconnection this moment is connected with said FXO interface; Then can make user's conversation automatically interrupt if the user dials pstn telephone through the FXO interface this moment.
Summary of the invention
In view of this, be necessary to provide a kind of user of avoiding to dial the method for interrupted router of PSTN and control conversation connection thereof through the FXO interface.
Router in the embodiment of the present invention comprise the outside exchange subscriber interface, FXS interface, be electrically connected to said outside and exchange subscriber relay, testing circuit and control circuit between interface and the said FXS interface; Exchange subscriber interface and be connected to telephone set in said outside; Said FXS interface is connected to the public switch telephone network road; When router cut off the power supply, said testing circuit was used to detect said outside and exchanges subscriber whether be in on-state between interface and the said telephone set; Said control circuit is used for controlling according to the power-up state of the testing result of said testing circuit and said router the on off state of said relay; If said outside exchange subscriber and said telephone set between be in on-state, then said control circuit is kept closed said relay.
As further improvement of the present invention; If said outside exchange subscriber and said telephone set between be in the state of hanging up; And said router re-powers, and then said control circuit makes said relay break off said outside to exchange subscriber being connected between interface and the said FXS interface.
As further improvement of the present invention, whether said testing circuit is exchangeed subscriber and is had electric current to flow through between interface and the said relay to judge said outside to exchange subscriber interface and said telephone set time whether to be in on-state through detecting said outside.
As further improvement of the present invention, said relay also comprises indicating device, and said indicating device is used to indicate said telephone set and said outside to exchange subscriber the connection status between the interface.
As further improvement of the present invention, to exchange subscriber when connecting between the interface when said telephone set and said outside, said indicating device is shinny; Exchange subscriber when hanging up between the interface when said telephone set and said outside, said indicating device extinguishes.
The method that router control conversation in the embodiment of the present invention connects comprises the steps: the router outage; Said testing circuit detects said outside exchanges subscriber whether be in on-state between interface and the said telephone set; Exchange subscriber when being in on-state between interface and the said telephone set when said outside, said control circuit is controlled said relay and is kept closed.
As further improvement of the present invention; Whether said control circuit detects said router and re-powers; Exchange subscriber when said outside and to be in the state of hanging up between interface and the said telephone set; And said router re-powers, said control circuit control said relay break off said outside exchange subscriber with said outside Fabric Interface between be connected.
As further improvement of the present invention, to exchange subscriber when being in on-state between interface and the said telephone set when said outside, said indicating device is shinny.
As further improvement of the present invention, to exchange subscriber when said outside and to be between interface and the said telephone set when hanging up state, said indicating device extinguishes.
Compared to prior art; Router of the present invention is by being provided with testing circuit and detecting said telephone set and whether said FXS interface being in on-state; Said control circuit is controlled said relay by the testing result of said testing circuit and the power-up state of said router; Promptly when said FXS interface and said telephone set are in on-state; No matter whether said router re-powers; Said relay all is kept closed; Keeping being connected between said FXS interface and the said FXO interface, can guarantee that so telephone set can not interrupt because router re-powers dialing pstn telephone.
