The present invention proposes a kind of VOIP bimodulus gateway system, it is a kind of while the system that connects PSTN network and VOIP networks and can automatically switch therebetween, the system includes bimodulus handover module, FXS interface modules, speech processing module and software control module, FXS interface circuits connect speech processing module, speech processing module connects software control module, software control module is connected by Ethernet PHY chip with RJ45 interfaces, FXS interface circuits connect bimodulus handover module, and bimodulus handover module connects several RJ11 interfaces.Bimodulus gateway system architectures proposed by the present invention are reasonable, there is reduce equipment physical port quantity with can imitating by the system, any change need not be done to pbx switch, VOIP networks or PSTN network can be selected with unrestricted choice or by gateway, with good practicality flexibility.
Description
Technical field
The present invention relates to art communication systems field, and in particular to a kind of VOIP bimodulus gateway system.
Background technology
Recently as broadband network and growing, VoIP (the Volee over Internet of IP technologies
Protoc01) application of technology is more and more extensive.Gateway is the visual plant in voip network, can be divided into electricity according to application field
Believe level gateway and user terminal gateway.User terminal gateway device is mainly used in cell and enterprise, is connection terminal telephone and IP network
The bridge of network, major function is to carry out encoding and decoding speech, signaling processing, VoIP protocol processing and Routing Protocol processing etc..
Bimodulus refers to VoIP and PSTN both of which.Bimodulus gateway is a kind of while connecting PSTN network and voip network simultaneously
The user terminal gateway device that can automatically switch therebetween.Bimodulus gateway can use voip network to save and largely converse into
This, can also ensure that telephone line is forever smooth when (power off or route and be unreachable) unavailable in voip network using PSTN network
It is logical, and any change need not be done to pbx switch using bimodulus gateway, user can be with unrestricted choice or automatic by gateway
Selection uses voip network or PSTN network, with good practicality and flexibility.
The content of the invention
It is an object of the invention to provide a kind of VOIP bimodulus gateway systems with good practicality and flexibility.
The present invention is achieved through the following technical solutions：
A kind of VOIP bimodulus gateway system is a kind of while connecting PSTN network and VOIP networks and can cut automatically therebetween
The system changed, the system includes bimodulus handover module, FXS interface modules, speech processing module and software control module, institute
FXS interface circuits connection speech processing module is stated, the speech processing module connects software control module, and the software controls mould
Block is connected by Ethernet PHY chip with RJ45 interfaces, and the FXS interface circuits connect bimodulus handover module, the bimodulus
Handover module connects several RJ11 interfaces；
The FXS interface circuits include codec CODEC and SLIC SLIC, the codec CODEC bags
Include an analog-digital converter and a digital analog converter；
The bimodulus handover module includes FXO interface circuits, and the FXO interface circuits are by codec CODEC and data processing
Array DAA is constituted；
The speech processing module is responsible for that PCM audio digital signals are compressed and decompressed；
The software control module realizes protocol stack processing and the route processing of gateway.
Further, the SLIC SLIC simulating PSTN voltages, can detect the dislodging machine of phone and can produce
Raw 120V ringing-current voltage.
Further, the data processing array DAA emulates a phone, is removed by providing PSTN loop closure
HVDC component, the analog AC signal only allowed on PSTN lines passes through.
Further, G.711, G.723.1 and G.729 the standard of the compression algorithm is included, and compression algorithm can be with firmly
Part DSP is realized or realized by pure software.
Further, the protocol stack is responsible for the data flow after compression being packaged, and adds IP agreement packet header, formation can
The IP packets transmitted in VOIP networks.
The beneficial effects of the invention are as follows：Rationally, have by the system to imitate bimodulus gateway system architectures proposed by the present invention
Reduce the physical port quantity of equipment in ground, it is not necessary to any change is done to pbx switch, can be selected with unrestricted choice or by gateway
VOIP networks or PSTN network, with good practicality flexibility.
