Abstract

The utility model provides a two-machine one-number fixed wireless telephone which can be externally connected with a common fixed telephone. The two-machine one-number fixed wireless telephone comprises a fixed wireless telephone which adopts wireless method to realize incoming call and outgoing call. A wireless module with a master control function and a power supply circuit are arranged in the telephone. The wireless module is electrically connected with the interface circuit of the common fixed telephone through a DTMF number-receiving module, an audio processing circuit and an off-hook and on-hook detection circuit. The power supply circuit supplies power to the DTMF number-receiving module, the audio processing circuit, the off-hook and on-hook detection circuit and the interface circuit of the common fixed telephone. The utility model has the advantages that the telephone uses the existing common fixed telephone as an auxiliary telephone, the auxiliary telephone is enabled to realize wireless incoming call and wireless outgoing call through the fixed wireless telephone, and the two telephones share a same number.

Description

Two-shipper jack per line fixed wireless telephone

Technical field

The utility model relates to a kind of fixed wireless telephone device that can external normal telephone machine.

Background technology

General fixed wireless telephone is by setting up wireless communication module in phone inside, makes the telephone device of shape such as normal telephone machine adopt the voice call-in and call-out functions of wireless transmission.This kind fixed wireless phone is suitable as public words and uses or use as office telephone in office.Along with the reduction that reaches relevant cost of improving of wireless telephony network, fixed wireless telephone begins for the PSTN landline telephone and urges the related application that makes new advances.Part business user group wishes that radio apparatus both used also as a private telephone use and uncommon phone set terminal as public words, but opening 2 numbers uses 2 cover radio apparatus can increase their operating cost undoubtedly, and when using as public words, the phone user is the general population, use habit differs, and easily radio apparatus is caused damage; Increase operation rate for 2 terminals at office occasion jack per line.So a kind of device that uses same number resource to have two telephone terminals of market active demand.

Summary of the invention

The purpose of this utility model provide a kind of can external normal telephone machine, thereby realize the fixed wireless phone device of two-shipper jack per line.

For achieving the above object, the utility model has been taked following technical scheme:

Two-shipper jack per line fixed wireless telephone, comprise and adopt wireless mode to realize the fixed wireless telephone device that incoming call is breathed out, be provided with wireless module and power circuit in this phone device inside with master control function, especially, described wireless module by DTMF collect the digits module, audio frequency processing circuit and picking/hanging machine detection circuit, is electrically connected with the ordinary telephone set interface circuit respectively; Described power circuit provides electric energy to collect the digits module, audio frequency processing circuit, picking/hanging machine detection circuit and secondary machine interface circuit of DTMF.

Described fixed wireless telephone device is by casing, handle, wireless module with master control function, and the handset circuitry that is electrically connected with wireless module, handfree circuit, key-press matrix, LCD MODULE and SIM card constitute; Also comprise the power circuit that electric energy is provided to above-mentioned each module and circuit.

Below operation principle of the present utility model is described:

After wireless module with master control function refers to this wireless module and handset circuitry, key-press matrix, LCD MODULE, SIM card, power circuit are connected, can realize being similar to the call-in and call-out functions of mobile phone independently.This wireless module is installed in the casing that is similar to landline telephone, and is used as fixed telephone.Yet, by this phone is improved, increase such as DTMF collect the digits module, audio frequency processing circuit, picking/hanging machine detection circuit and normal telephone machine interface circuit etc., can realize the wired phone of common PSTN is connected on the fixed wireless telephone, and realize the compatibility and the co-ordination of communication interface between the two.The normal telephone machine also can be dialed or be received calls by wireless module, has finally realized two-shipper jack per line function.

Technique effect of the present utility model is: this telephone set will have common landline telephone now as secondary machine, allow secondary machine also can realize wireless incoming call exhalation by the cellular phone machine, and the shared same number resource of two-shipper.

Description of drawings

Fig. 1 is the structure calcspar of the utility model embodiment.

Description of reference numerals: 1-wireless module; 2 power circuits; The 3-handset circuitry; The 4-handfree circuit; The 5-key-press matrix; The 6-LCD MODULE; The 7-SIM card; The 8-DTMF module that collects the digits; The 9-picking/hanging machine detection circuit; The 10-audio frequency processing circuit; 11-normal telephone machine interface circuit.

Embodiment

Below in conjunction with drawings and Examples the utility model content is described further.

As shown in Figure 1, the fixed wireless telephone device is by the wireless module 1 with master control function, and the handset circuitry 3 that is electrically connected with wireless module 1, handfree circuit 4, key-press matrix 5, LCD MODULE 6 and SIM card 7 constitute; Also comprise the power circuit 2 that electric energy is provided to above-mentioned each module and circuit.Above electronic installation is installed in respectively in casing and the handle, constitutes and adopt wireless mode to realize the fixed wireless telephone device that incoming call is breathed out.

In the inside of fixed wireless telephone device, DTMF collect the digits module 8, audio frequency processing circuit 10, picking/hanging machine detection circuit 9 and normal telephone machine interface circuit 11 are set.Collect the digits module 8, audio frequency processing circuit 10, picking/hanging machine detection circuit 9 of DTMF is electrically connected with wireless module 1 respectively, also is electrically connected with normal telephone machine interface circuit 11 respectively simultaneously.Like this, the compatibility of signal between normal telephone machine and the wireless module 1 be can realize, thereby fixed wireless telephone phone device and the co-ordination in use of normal telephone machine realized:

(1) when the user uses fixed wireless telephone to set up traffic, wireless module 1 can detect the user key-press content by key-press matrix 5, and on LCD MODULE 6, show relevant information, calling connects by the radio circuit and the wireless base station of wireless module 1 inside, and voice play back through handset circuitry 3 or handfree circuit 4.

(2) when the user uses the normal telephone machine to set up traffic, wireless module 1 at first detects the action of user's off-hook by picking/hanging machine detection circuit 9, detect the numbers that the user dialled and translate to the signal format that wireless module 1 can receive by collect the digits module 8 of DTMF then, radio circuit and the base station by wireless module 1 inside connects at last.The voice signal of wireless module 1 is fed on the plug-in normal telephone machine by audio frequency processing circuit 10, normal telephone machine interface circuit 11, realize the voice forwarding between fixed wireless telephone and the normal telephone machine, similarly, the voice of normal telephone machine also can be forwarded on the wireless module 1 by normal telephone machine interface circuit 11, audio frequency processing circuit 10.

Normal telephone machine interface circuit 11 except that realizing that voice are transmitted, also has collect the digits module 8, picking/hanging machine detection circuit 9 of DTMF is docked to the function of normal telephone machine in the utility model.

What this specification was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under operation principle of the present utility model and thinking all are considered as protection range of the present utility model.
