Yet this telephone set is only supported the audio call in the PSTN network and is not supported VOIP (Voice overIP, IP-based voice).On the other hand, this telephone set only supports a PC to dial up on the telephone by netting twine, can't realize that multiple pc surfs the Net simultaneously, does not also support WLAN (wireless local area network).

The utility model content

The utility model embodiment provides a kind of telephone set, to support VOIP business and constructing local network.

For achieving the above object, embodiment of the present utility model adopts following technical scheme:

A kind of telephone set is provided, comprises: Switching Module, data module, phone module and separation module; Wherein,

Described Switching Module arrives described data module with the data of local area network (LAN); Described phone module converts voice signal to low frequency signal and is transferred to described separation module or described voice signal is transferred to described data module; Described data module converts described data-signal to high-frequency signal and sends to described separation module behind network address transmission, and/or sends to described separation module after converting described voice signal to high-frequency signal; Described separation module is transferred to communication network with described high-frequency signal and/or described low frequency signal; Perhaps

Described separation module receives the external signal of described communication network, isolates high-frequency signal and/or low frequency signal from described external signal, and described low frequency signal is transferred to described phone module, and described high-frequency signal transmission is arrived described data module; Described data module converts described high-frequency signal to data-signal and/or voice signal, and described data-signal is transferred to described Switching Module behind network address transmission, and described voice signal is transferred to described phone module; Described Switching Module is with the user terminal of described data in the described local area network (LAN).

The telephone set that the utility model embodiment provides, on the one hand, data module outwards sends after the voice signal that phone module receives can being converted to high-frequency signal, and the voice signal power supply words that also the high-frequency signal transfer that receives can be swapped out module is answered, and has realized the VOIP function.On the other hand, this data module has network address transmission and routing function, and data module can convert data-signal to high-frequency signal and send to separation module behind network address transmission; Or convert high-frequency signal to data-signal, data-signal is transferred to Switching Module and user terminal behind network address transmission; Support Switching Module and many user terminal constructing local networks.And user's online the time can be opened the VOIP business.

Fig. 2 outwards transmits the information flow direction figure of information for telephone set shown in Figure 1;

Fig. 3 is the information flow direction figure of the inside transmit outer information of telephone set shown in Figure 1.

Embodiment

Below in conjunction with accompanying drawing the communication system that the utility model provides is described in detail.

The utility model provides a kind of telephone set.As shown in Figure 1, this telephone set comprises: Switching Module 1, data module 2, phone module 3 and separation module 4.It is as follows that each forms the function division of module:

Switching Module 1 sends to the local area network (LAN) information transmitted on the corresponding route, finishes the exchange of information.This user terminal can be the PC and the network printer etc.This user terminal can connect Switching Module 1 by netting twine, also can utilize Radio Resource and Switching Module 1 to set up wireless connections.

Data module 2 has routing function, supports NAT (Network Address Translation, network address transmission) function, is used for converting the inner private network address of local area network (LAN) to the legal network address.But also outwards send after the voice signal that phone module receives can being converted to high-frequency signal, the voice signal power supply words that also the high-frequency signal transfer that receives can be swapped out module is answered, to support the VOIP function.

Phone module 3 can be realized voice signal freely switching in PSTN and VOIP (Public Switched TelephoneNetwork, PSTN) network.When carrying out audio call by PSTN, phone module 3 is transferred to separation module 4 after converting voice signal to low frequency signal, and separation module 4 sends to this low frequency signal outside communication network again.When the user carries out audio call by the VOIP network, earlier this voice signal after converting high-frequency signal to, data module 2 is outwards sent by data module 2 again.

Separation module 4 is integrated separator, the user can dial or answer VOIP or pstn telephone in the time of online.Separation module 4 can pass through optical fiber, cable or digital subscriber line etc. and connect communication network.

For convenience of description, in the present embodiment with local area network (LAN) in the mutual information of user terminal be referred to as data message.When the telephone set that the utility model provides outwards transmitted information, according to information flow direction figure shown in Figure 2, each functional module was carried out following operation:

On the one hand, to data module 2, data module 2 converts data-signal to high-frequency signal and sends to separation module 4 Switching Module 1 behind network address transmission with the data of local area network (LAN), separation module 4 with high-frequency signal transmission to communication network.On the one hand, phone module 3 is transferred to data module 2 with voice signal, and data module 2 sends to separation module 4 after converting voice signal to high-frequency signal, and separation module 4 arrives communication network with high-frequency signal transmission; Perhaps, phone module 3 converts voice signal to low frequency signal and is transferred to separation module 4, and separation module 4 is transferred to communication network with low frequency signal.When separation module 4 receives high-frequency signal and low frequency signal simultaneously, the low frequency signal that will receive from phone module 3 and be mixed into the low-and high-frequency signal from the high-frequency signal that data module 2 receives and be transferred to communication network.

The telephone set that the utility model provides is when inside transmit outer information, and according to information flow direction figure shown in Figure 3, each functional module is carried out following operation:
