Background technology

IP network has been one of requisite working environment of company and enterprise at present, and the appearance of voip technology makes the transmission network of voice-and-data obtain unification, makes the user reduce cost when the network of investment base.The Voip phone is the terminal equipment of VoIP system, and user side equipment, the major function of its realization is that the sound with the user imports system into by receiver, then through the A/D conversion, by analog signal conversion is digital signal, after this digital signal was encoded, encapsulated packing through special-purpose encode processor again, by network interface chip, promptly network process module sent on the IP network at last; Same, network process module sends to special-purpose decoding processor with the packet of the speech coding received and decodes, decoded audio digital signals sends to D/A converter again and handles, finish the conversion of digital to analogy signal, at last the analog voice signal that obtains is passed to the caller by player, see shown in the accompanying drawing 1.

Because above-mentioned Voip telephone plant must take a network line, and in actual use, this circuit must be communicated with Internet, this uses the Voip phone can cause some problems with regard to causing, at first, being necessary for the Voip phone in the office space increases the connector of a network, and more seriously, the circuit that often connects Internet in some little office spaces has only one, in case taken by phone, other the network equipment just can't be connected to Internet, such as office computer.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of the Voip phone has been carried out new function design and exploitation, makes it to have the Voip telephone plant of band dialer functions.The utility model can be supported multiple network access, comprise fixedly IP, dynamic IP and PPPoE dialing etc., the more important thing is, phone provides two network interfaces, an interface is used to connect outside Internet network, another interface is used to miscellaneous equipment that the service of bridge joint or route agent is provided, and inserts with the Internet that guarantees miscellaneous equipment.

The utility model mainly is made up of following several nucleus modules, comprise analog voice receiver and transmitter, encode processor, decoding processor, A/D and D/A converter, network process module, described voice call receiver links to each other with A/D converter, A/D converter links to each other with encode processor, and this encode processor is packaged into the packet that can transmit based on IP to the network process module that links to each other with code stream in the mode of fixed length; Described network process module oppositely is connected with decoding processor, D/A converter and the player of realizing inverse process in turn.

Described network process module is provided with at least two interfaces, and an interface is connected in outside Internet network, and another interface is connected in the internal network that the Internet that makes miscellaneous equipment inserts usefulness.

Described encode processor mainly comprises G711, G723 and G729 compression coding mode and the data Audio Signal Compression Coding is produced the code stream of 64kbps, 5.3kbps and 16kbps that above-mentioned code stream is transmitted on the network process module that joins with it.

Described network process module consists predominantly of PPPoE dialing unit, TCP/IP processing unit, MAC Address Dispatching Unit, physical interface 1 and physical interface 2, and wherein physical interface 1 connects the Internet network, connects internal network with physical interface 2.

The utility model belongs to the improvement to prior art, uses in actual environment, and this equipment can solve the applicable cases of IP interface deficiency really, obviously reduce the user to IP interface wiring quantity, save cost, had characteristics such as rational in infrastructure, practical and convenient, reliable.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing 2, the utility model mainly is made up of following several nucleus modules, comprise analog voice receiver and transmitter, encode processor, decoding processor, A/D and D/A converter, network process module, described voice call receiver links to each other with A/D converter, A/D converter links to each other with encode processor, and this encode processor is packaged into the packet that can transmit based on IP to the network process module that links to each other with code stream in the mode of fixed length; Described network process module oppositely is connected with decoding processor, D/A converter and the player of realizing inverse process in turn.

At first, this equipment provides the basic function of Voip phone as the Voip telephone plant, and the basic principle of its realization and mode are:

The voice call receiver, be converted to the signal of telecommunication of simulation, be sent to A/D converter, A/D converter passes through the sample frequency of 8K or 16K hertz to analog signal sampling, with analog signal conversion is digital signal, after finishing analog-to-digital conversion, this digital audio signal is sent in the encode processor encodes, encode processor as required, the data audio signal is carried out different compressed encodings, mainly comprise G711, several compression coding modes of G723 and G729 produce 64kbps respectively, 5.3kbps and the code stream of 16kbps, then, these code streams are packaged into the packet that can transmit based on IP in the mode of fixed length in encode processor, last, these packets are sent to network process module, by this module packet are sent to the designated destination; Conversely, network data model sends the packet of receiving to decoding processing, by an inverse process finish decoding, number is touched conversion, is triggered the player transmission by the signal of telecommunication at last, finishes listening to of the other side's voice.What will emphasize a bit here is, by the co-ordination of encoder, adopts suitable algorithm, and this equipment can provide the echo cancelltion of 32ms to handle, and is higher than common circuit echo far away and offsets and handle.

Shown in the accompanying drawing 3, in order to solve the problem of front, we carry out following design and realization to network process module, the PPPoE dialing unit that mainly comprises, TCP/IP processing unit, MAC Address Dispatching Unit, physical interface 1 and physical interface 2.

The PPPoE realization of dialling: when reality was used, we connected Internet with physical interface 1, connected inner IP network with physical interface 2.When needs Voip phone carries out the PPPoE dial-up connection, the PPPoE dialing unit is according to relevant configuration, be packaged as the normal data bag of PPPoE standard, send to the data link layer Dispatching Unit, by this unit, packet is superposeed behind MAC (physical address) head, encapsulation sends on the Internet by physical interface 1 at last once more, and the infomational message of finishing service provides with network authentication, the network address etc. is mutual, the final PPPoE process that realizes makes equipment can be connected to Internet.

The internal network online realizes: when internal network needs and Internet get in touch, it at first sends to this equipment to packet by physical interface 2, interface 2 sends to the data link layer Dispatching Unit with this packet, this unit extracts the MAC in this packet and preserves, and then this packet sent to interface 1, send on the Internet by interface 1 at last; After coming packet to obtain on the Internet by physical interface 1, interface 1 sends to the data link layer Dispatching Unit with this packet immediately, this layer extracts MAC from packet, compare then, if the MAC of oneself, after then this packet being removed the encapsulation of MAC head, pass to the TCP/IP processing unit, finish corresponding conversation and handle (front is described); If find it is the MAC from the packet of interface 2 of record, then will directly be transmitted to interface 2 to packet, deliver to internal network by interface 2, so far, just realized between internal network and Internet alternately; Last if find it is that unacquainted MAC then directly loses this packet, do not do other processing.
