Fig. 1 is a functional block diagram of the present invention.
Fig. 2 is the schematic diagram of integrated network telephone of the present invention.
The schematic diagram that Fig. 3 is connected with computer for integrated network telephone of the present invention.

Embodiment
A relevant preferred embodiment with integrated network telephone distributor of exchange distribution function of the present invention, with Ethernet (Ethernet) as operating environment, please be earlier with reference to the shown functional block diagram of Fig. 1, it mainly is made up of networking port one 1,12, memory storage 2, package sorter 3 and speech processing circuit 4.Wherein package sorter 3 comprises main members such as separating package circuit 31, mark comparison circuit 32, package sorting circuit 33, switching and packetized circuit 34, mark partitioning circuitry 35.
Aforesaid networking port one 1,12 is a networking card, and its function is mainly used to receive or transmit the networking package.Networking port one 1,12 can be respectively two an outpost of the tax offices of throwing the net, and also can be integrated into a networking card that comprises two connectors certainly.Memory storage 2 comprises a read-only memory (ROM) and a random-access memory (ram), in order to store package mark (Token) table of comparisons and the packet type table of comparisons and networking packet information.Certainly, RAM also can use flash memory to be replaced.
Package sorter 3 utilizes special purpose integrated circuit (IC) design (ASIC) technology to finish, the networking package that its function is mainly received networking port one 1 processing of classifying, and the networking package is voice data packet or Datagram to distinguish that network telephone is received.If then delivering to speech processing circuit, voice data packet carries out speech processes conversion and the output voice signal, if Datagram is then directly delivered to coupled PC.
When this routine integrated network telephone receive via networking port one 1 one transmitted on by Ethernet the networking package time, the package circuit 31 separated in the package sorter 3 carries out package cutting to the networking package earlier, to be cut into networking packet header and the networking packet information that has only data (Data) part of (Header) part of having only header.And the networking packet information is delivered to memory storage 2 kept in, the networking packet header is delivered to mark partitioning circuitry 35.
Because the networking package contains many fields (Field), so after mark partitioning circuitry 35 is received the networking packet header, can be with taking out in the packet header of networking each in order to make the field of classification usefulness, and with the field that takes out as mark (Token), and the mark of these taking-ups is lined up a sequence in regular turn passes to mark comparison circuit 32 again to carry out a comparison process.
Mark comparison circuit 32 just compares according to the stored package mark table of comparisons in field under each mark and the memory storage 2.There is a mark rule (TokenRule) package mark table of comparisons the inside, for example:
Field(Destination?MAC?Address?Byte1)
Range(0xff，0x13，…)
Value(0)
Range(0x00，0x12，…)
Value(1)
After mark comparison circuit 32 is finished comparison, comparative result is delivered to package sorting circuit 33 with the packet type table of comparisons in the contrast memory storage 2, judge received networking package.If judged result is voice data packet, then notice is switched the networking packet information that will be temporary in the storage device 2 with packetized circuit 34 and is taken out, and is sent to speech processing circuit 4, carrying out a conversion process, and the output voice.If judged result is not a voice data packet, represent that then this networking package is general Datagram, switch with packetized circuit 34 and will be reassembled as a networking package to networking packet header and networking packet information again, and see off by networking port one 2.
Above-mentioned switching and packetized circuit 34 can be set and keep certain frequency range for the transmission voice, and the flow that provides a QoS mechanism to guarantee voice data packet can be in the size of 64K, to determine the communication quality of voice call.
Fig. 2 shows the integrated network telephone schematic diagram that this is routine, has two connector A and B at network telephone itself, and A is connected to Ethernet, and B then is used for connecting PC.Certainly, the user also can set up several connectors more, in order to connect not only one PC.
Fig. 3 shows the schematic diagram that this routine integrated network telephone is connected with two PC.These two PC only utilize the IP address at network telephone place come with the networking on other PC link mutually.And receive networking package on the networking when seeing through network telephone, can utilize mark in the package of networking to judge this networking package is the PC of delivering on that connector (Port).
Fig. 4 demonstrates this routine integrated network telephone and sees through and to be connected to Ethernet, can via an IP phone gateway (IP Telephone Gateway, ITG) with traditional Public Switching Telecommunication Network road in phone link mutually.Certainly, also can link mutually with the PC that this routine integrated network telephone township connects with other computers on the Internet.
By above explanation as can be known, the present invention sorts out Datagram on voice data packet and the general networking by the package sorter with received networking package.And with voice data packet through speech processing circuit convert to voice with output, Datagram is delivered to coupled PC by the networking port.And switching in the package sorter and packetized circuit still have a QoS mechanism, can keep the voice frequency range of a 64kbps, to guarantee good communication quality.And because network telephone and computer doubling, saved use RJ-45 line and reduced the networking wiring space in a large number.Because of the connector with the networking can be set directly on the network telephone, reduce demands such as hub or networking interchanger widely again.
It should be noted that above-mentioned many embodiment only give an example for convenience of explanation, the interest field that the present invention advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
