Above-mentioned switch 413 couples the first telecommunications connectivity port 411, the second telecommunications connectivity port 412, DAA unit 414, SLIC unit 415 respectively, reaches audio codec 416, switches for annexation and the telephony mode of switching the first telecommunications connectivity port 411, the second telecommunications connectivity port 412, DAA unit 414 according to the control of this audio codec 416, reach between the SLIC unit 415.
For example: under the regular phone pattern, switching by switch 413, the first telecommunications connectivity port 411 electrically connects the second telecommunications connectivity port 412, makes traditional phone 402 can normally call to public switched telephone network road (PSTN) 403 or answers phone from public switched telephone network road (PSTN) 403.Under the network telephone pattern, switching by switch 413, the first telecommunications connectivity port 411 can electrically connect DAA unit 414 maybe can electrically connect SLIC unit 415, thus the telecom switching module 41 that traditional phone 402 can be by computer installation, South Bridge chip 44, and networking card module 42 dial/answer network telephone.Note that under the network telephone pattern the first telecommunications connectivity port 411 does not electrically connect with the second telecommunications connectivity port 412.In other embodiments, telephone path that 413 of switchs can provide is switched, 41 functions that can provide of also visual telecom switching module and different.
In present embodiment, DAA unit 414, and the function that provided of SLIC unit 415 similar with typical DAA and SLIC.That is typical SLIC unit is an end that is mounted on telecommunications company, and it is in order to providing voltage to black phone, and typical DAA unit is mounted on an end of black phone.And the DAA unit 414 that present embodiment provided is corresponding with the SLIC unit that is mounted on local side, so that the user on the end of networking can call by 414 emulation of DAA unit, traditional phone 402 can be answered network telephone by SLIC unit 415.
That is to say that DAA unit 414 can provide that power supply draws, and analogue simulation telephony feature, answering network telephone, and DAA unit 414 can convert the network telephone based on digital package to the employed analog signal in regional public switched telephone network road.SLIC unit 415 can provide power feed, dialing tone, reach detecting traditional phone 402 formed loop circuits.
Above-mentioned audio codec 416 couples switch 413, DAA unit 414, SLIC unit 415 respectively, reaches connecting interface 48.In present embodiment, audio codec 416 can provide a controlled function, reach the encoding and decoding speech function.Furtherly, audio codec 416 can be controlled switch 413, DAA unit 414, and the operation of SLIC unit 415.In addition, audio codec 416 can be converted to audio digital signals with analog voice signal, perhaps audio digital signals is converted to analog voice signal.
In present embodiment, aforementioned telecom switching module 41 is one to be inserted in the expansion board of the motherboard of computer installation, and in other embodiments, telecom switching module 41 also can directly be integrated on the motherboard.In present embodiment, the connecting interface 48 of interconnecting module 41 is universal serial (Universal Serial Bus, USB) interface, interface such as in other embodiments, the connecting interface 48 of interconnecting module 41 also can be 1394, PCI, PCI Express, AC97 or Azalia.
Next, function and the operation thereof that is integrated in the telecom switching module 41 of computer installation and is provided will further specify following.
Would like to ask in the lump with reference to Fig. 4 and Fig. 5.Under normal mode, the first telecommunications connectivity port 411 is by switch 413 and 412 electric connections of the second telecommunications connectivity port, thus the user desire to dial/to answer pstn telephone the same with known use black phone, and need not change its operation behavior.
When the user desired to diall network telephone, the user can (for example: the * keyboard), so that switch 413 switches, change its annexations for the first telecommunications connectivity port 411 be located at preset key on the traditional phone 402 by pushing one group.For example: the user by be pressed in push preset key on the traditional phone 402 after, audio codec 416 is according to its received dual-tone multifrequency (DualTone Multi Frequency, DTMF) signal is controlled switch 413 and is switched, so that the first telecommunications connectivity port 411 electrically connects by switch 413 and DAA unit 414.Thus, traditional phone 402 just can by telecom switching module 412, South Bridge chip 44, and networking card module 42 diall network telephone.
For example, the user is pushing preset key with after switching to the network telephone pattern, the user can push default speed and dial the number and diall network telephone, for example: speed is dialled the number and 111 is represented first friend AAA of the address book in the network telephone software, dials the number and 111 just can diall network telephone to friend AAA so push speed on traditional phone 402.In addition, the user pushes after speed dials the number, DAA unit 414 just can produce dial action, and the analog voice signal that audio codec 416 can be produced DAA unit 414 converts audio digital signals to, then audio codec 416 is delivered to South Bridge chip 44 by connecting interface 48 with audio digital signals, transfers to Internet 401 by networking card module 42 then.In other embodiments, the user also can push a preset key group switches a network telephone pattern, and for example: the preset key group is " * 77 ".
Similar ground, when a network telephone is dialed to computer installation by Internet 401 ends, then audio codec 416 can switch by control switch 413, make the telecommunications connectivity port 411 of winning electrically connect SLIC unit 415, can answer network telephone by SLIC unit 415 for traditional phone 402.Certainly, in other embodiments, also can make the second telecommunications connectivity port 412 electrically connect DAA unit 414, can be forwarded to traditional phone or the mobile phone that other user sets by public switched telephone network road 403 for network telephone by the switching of switch 413.
By above explanation as can be known, preferred embodiment of the present invention is integrated into telecom switching module in the computer installation, by the connection of switching telecom switching module, and can realize dialing or answer network telephone with traditional phone, and telecom switching module is directly to be integrated in the computer installation, and does not have the problem of compatibility and control.
The foregoing description only is to give an example for convenience of description.Yet do not breaking away under the spirit of the present invention, this technical field that the present invention belongs to tool knows that usually the knowledgeable can be understood easily by the content that this specification disclosed, and carries out various modifications and change.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.
