Abstract
The utility model provides a standby device for an internet phone gateway, comprising an interface of a gateway and a public exchange phone network, wherein the interface of the gateway and the public exchange phone network and the interface of the gateway and an internet network are connected with the internet phone gateway through an alternative switch. A Lifeline key technology is that the standby device can automatically switch to a PSTN (Public Switched Telephone Network) line to call/answer the phone; when the gateway is in operation and the network is selected not to be accessed, or the PSTN phone can be dialed and answered through the lifeline through the calling section. The standby device of internet phone gateway is produced based on above problems, which is capable of realizing a simple and reliable hardware lifeline interface with low cost.
Description
Technical field
The utility model relates to the reliability field of communication system, and is particularly a kind of after the communication network signal interruption, the gateways for network telephone call back-up device that can use the PSTN communication network to work on.
Background technology
VoIP (Voice over Internet Protocol) is a kind of based on IP phone, and releases the technology of corresponding value-added service.The advantage of VoIP maximum is to adopt the environment of Internet and global ip interconnection widely, and, better service more than traditional business are provided.In essence, voip phone and Email, instant messaging or webpage do not have any difference, and they all can transmit at the machinery compartment that has passed through Internet connection.These machines can be computers, and perhaps wireless device is such as mobile phone or hand-held device or the like.At present, voip gateway is all got in touch by the Internet, if the Internet interrupts cutoff call may be brought loss.Therefore, need a spare communication interface, at present, this spare communication interface is called Lifeline, and English is meant escaping exit.On the IAD equipment that generally is meant in portlet, 1-2 interface can be provided, can be directly connected on the telephone wire of PSTN (common telephone network), obstructed even outage is connected below the IAD one one or 2 telephone sets and can also makes a phone call by PSTN when IP network.
The at present existing support that can support the voip gateway of escaping exit by the realization of FXO interface.Call out though also can reach PSTN (promptly), exist some obviously not enough, be in particular in:
1 response is slow, and 2 realize complexity.
Summary of the invention
For the lifeline that overcomes present voip gateway brings the deficiency of loss, the utility model provides a kind of back-up device.
The utility model in order to realize the technical scheme that its technical purpose adopts is: a kind of back-up device of gateways for network telephone call, described back-up device comprises the interface of gateway and PSTN, and described gateway is connected with described gateways for network telephone call by either-or switch with the Internet interface with gateway with the interface of PSTN.
Further, in the back-up device of above-mentioned gateways for network telephone call: the interface of described gateway and PSTN comprises by the ring detecting circuit of gateways for network telephone call governor circuit control, PSTN wireline inspection circuit and simulation circuit for answering.
Concrete, in the back-up device of above-mentioned gateways for network telephone call: described either-or switch is the single-pole double throw relay by the control of gateways for network telephone call governor circuit.
The Lifeline key technology is that outage can automatically switch to PSTN circuit dialing/receiving telephone in the technical solutions of the utility model.If of course, after the gateway operation, also can select network obstructed, perhaps select to dial pstn telephone, and can answer pstn telephone by lifeline by calling out.The utility model arises at the historic moment based on the problems referred to above, has realized a kind of more simple, reliable, cheap hardware lifeline interface.
Below in conjunction with the drawings and specific embodiments the utility model is done comparatively detailed description.
Description of drawings
Fig. 1 is the utility model embodiment 1 system block diagram.
Embodiment
Embodiment 1, as shown in Figure 1, present embodiment is a kind of back-up device of gateways for network telephone call, this back-up device comprises the interface of gateway and common exchanging telephone network PSTN, and gateway is connected with described gateways for network telephone call by either-or switch with the Internet interface with voip gateway with the interface of PSTN.In the present embodiment, either-or switch is the single-pole double throw relay, and the single-pole double throw relay is controlled by the VoIP governor circuit.The interface of gateway and PSTN comprises by the ring detecting circuit of gateways for network telephone call governor circuit control, PSTN wireline inspection circuit and simulation circuit for answering.
In the present embodiment, voip gateway can allow the user when temporary derangement appears in network function, or can initiatively select after increasing the lifeline interface, uses traditional PSTN network to carry out phone call functions.
Ring detecting circuit, when the PSTN side had the bell signal incoming call, the VoIP governor circuit can detect this signal, thus control relay cuts passage toward the PSTN circuit;
PSTN wireline inspection circuit, VoIP governor circuit are by this circuit, and whether can detect the PSTN line side has the PSTN of insertion line, and whether the PSTN line side the line is busy the state of Denging, thus the corresponding switching state of may command relay;
The simulation circuit for answering, when the VoIP side was in talking state, the VoIP governor circuit can pass through this circuit, and the PSTN line side is placed busy condition, thereby made the circuit incoming call of PSTN side respond busy-flash signal.
Claims (3)
1. the back-up device of a gateways for network telephone call, it is characterized in that: described back-up device comprises the interface of gateway and PSTN, and described gateway is connected with described gateways for network telephone call by either-or switch with the Internet interface with gateway with the interface of PSTN.
2. the back-up device of gateways for network telephone call according to claim 1 is characterized in that: the interface of described gateway and PSTN comprises by the ring detecting circuit of gateways for network telephone call governor circuit control, PSTN wireline inspection circuit and simulation circuit for answering.
