Abstract
The utility model provides an ADSL (asymmetrical digital subscriber line) modulation and demodulation device. The device comprises an ADSL master control chip module, a SIM card driving module and a SIM card, wherein the SIM card driving module is connected with the ADSL master control chip module; the SIM card is connected with the SIM card driving module. The SIM card driving module converts a signal in the SIM card into a differential signal which can be identified by the ADSL master control chip module so that the signal can be received by the ADSL master control chip module. Compared to the prior art, by using the device of the utility model, the device supports an ADSL broadband network and also supports a 3G network; broadband Internet access and 3G Internet access through a telephone line are realized; the Internet access is convenient and is guaranteed; when the broadband network has a fault, a 3G mode can be switched into so that uninterrupted Internet access is guaranteed.
Description
Technical field
The utility model relates to ADSL broadband network termination, relates in particular to a kind of ADSL modulation-demodulation device.
Background technology
At present, having on the market a lot of ADSL modulation-demodulation devices, and the purposes of ADSL modulation-demodulation device just changes into the network signal of telephone line transmission broadband signal to realize consumer wideband networking.
In addition, 3G network has been realized the covering of most places, uses also more extensively, general, and smart mobile phone is also all supported 3G pattern by SIM card, improves 10 times have a surplus compared with 2G network speed, and the speed of download 500K/ of 3G network is about second, and network speed has improved much.Thereby 3G network will be more and more important.
Existing ADSL modulation-demodulation device only has by the single approach of telephone wire and transmits and obtain network signal, once the network of this approach of telephone wire breaks down, such as local side fault, line fault etc., cannot surf the Net.Yet present people are increasing to the dependence of network, such as sending out the very anxious mail of an envelope, to be ready sending, broadband suspension, will certainly cause unnecessary loss.
Utility model content
The technical problem that the utility model need solve is to provide a kind of ADSL broadband network of supporting, supports again the ADSL modulation-demodulation device of 3G network.
For solving above-mentioned technical problem, the utility model has designed a kind of ADSL modulation-demodulation device, it comprises ADSL main control chip module, also comprise the SIM card driver module being connected with ADSL main control chip module and the SIM card being connected with SIM card driver module, SIM card driver module converts the signal in SIM card to differential signal that ADSL main control chip module can identify and receives for ADSL main control chip module.
As the utility model, further improve, described ADSL modulation-demodulation device also comprises for the SIM card seat of SIM card is installed.
As the utility model, further improve, described ADSL modulation-demodulation device also comprises the WIFI communication module being connected with ADSL main control chip module.
As the utility model, further improve, described ADSL modulation-demodulation device also comprises the routing function module being connected with ADSL main control chip module.
Compared with prior art, the utility model ADSL modulation-demodulation device supports ADSL broadband network, supports again 3G network, realizes and surfing the Net by telephone wire broadband access network and 3G, surfs the Net convenient, more secure.When broadband networks breaks down, can switch to 3G pattern, ensure uninterruptedly online.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model ADSL modulation-demodulation device.
Embodiment
In order to make relevant technical staff in the field understand better the technical solution of the utility model, accompanying drawing below in conjunction with the utility model execution mode, technical scheme in the utility model execution mode is clearly and completely described, obviously, described execution mode is only the utility model part execution mode, rather than whole execution modes.
The utility model provides a kind of ADSL modulation-demodulation device, supports ADSL broadband network, supports again 3G network, realizes and surfing the Net by telephone wire broadband access network or 3G, surfs the Net convenient, more secure.
As shown in Figure 1, this ADSL modulation-demodulation device comprises ADSL main control chip module, the SIM card driver module being connected with ADSL main control chip module and the SIM card being connected with SIM card driver module.
For making SIM card can be installed on easily in ADSL modulation-demodulation device, in ADSL modulation-demodulation device, be also provided with SIM card seat, when SIM card being inserted to SIM card seat, SIM card is connected with SIM card driver module, and SIM card driver module converts the signal in SIM card to differential signal that ADSL main control chip module can identify and receives for ADSL main control chip module.Thereby, when SIM card, to insert in the utility model ADSL modulation-demodulation device, ADSL main control chip module can be identified, and processes, and utilizes SIM card to receive 3G network data and networks for user.
The utility model ADSL modulation-demodulation device also includes WIFI communication module and routing function module, and like this, utility model ADSL modulation-demodulation device possesses route and WIFI function, for user's online provides convenient approach.
Each functional module of the utility model ADSL modulation-demodulation device is all integrated into a single integrated structure, is located in the utility model ADSL modulation-demodulation device shell, makes the utility model ADSL modulation-demodulation device become a product that possesses multi-functional advantage.
The utility model ADSL modulation-demodulation device supports ADSL broadband network, supports again 3G network, realizes and surfing the Net by telephone wire broadband access network and 3G, surfs the Net convenient, more secure.When broadband networks breaks down, can switch to 3G pattern, ensure uninterruptedly online.
Below only expressed a kind of execution mode of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
