Description

Computer nework telephone interface board

Technical field

The present invention is a kind of networking telephone (VoIP) interface board, particularly a kind of computer nework telephone interface board.Be applied between computer (PC) and the ordinary telephone set, make computer, network telephone and ordinary telephone set three unification.

Background technology

At present, computer is extensively popularized, according to the China Internet Network Information Center (CNNIC) statistics, to the first half of the year in 2004 China netizen quantity broken through 8,700 ten thousand people.Illustrate that the Internet (Internet) plays an increasingly important role in masses' work, life.Meanwhile, also progressively rise, will play the part of important role in the communications field in future based on the voip network communication of Internet.

Have a kind of software of soft phone (Softphone) that cries can install on computers in the prior art, people can utilize microphone and earphone to converse behind the computer internet.Though it can be well and the computer combination, but because it is to use microphone and earphone, do not meet the custom that people make a phone call, and need operation system of computer and software to realize, just can not use under the situation of computer shutdown, using to the user makes troubles.Moreover be exactly that computer operating system often suffers virus attack, function can't normally be used.

Another kind is the voip phone machine of desktop, connects netting twine and just can independently use.But it relatively takes up space, and takies a plurality of interfaces, makes troubles also for user's use, and cost is also higher.So the user wishes can be with the computer and the networking telephone, in addition wish also incorporated ordinary telephone set, make operate more convenient.

Summary of the invention

The objective of the invention is to realize resource-sharing, can under the situation of not starting shooting, use phone as usual in order to solve the problem of computer, network (VoIP) telephone set and ordinary telephone set triplicity.The invention provides the computer nework telephone interface board of a kind of integrated network telephone (VoIP) function, can share an Ethernet interface (RJ45) with computer.Have a telephone installed on the keyboard cleaner handgrip and LCDs adopt keyboard just can call, and the while also can use under the computer shutdown situation as usual.

The technical scheme that the present invention is adopted for its technical problem of solution is: a kind of networking telephone interface board is provided, comprises the plug-in card and the keyboard of band computer interface plug.(Peripheral Component Interconnection, PCI) slot links to each other the existing peripheral component interface of the interface plug of plug-in card and computer.Do not change the original structure of computer, expand its function.Make full use of the space and the use habit of keyboard simultaneously, realize the three-in-one use of computer and network (VoIP) telephone set and ordinary telephone set.

Contain networking telephone processing module on the said plug-in card that is inserted on the computer PCI slot, realize the voip call processing capacity, it can make plug-in card make progress level-1 GK or soft switch registration, also can accept the calling from upper level gatekeeper or soft switch.

Also contain Ethernet interface (RJ45) on the plug-in card, be connected with Ethernet switch.Make it self possess the networking exchange capacity, can use for main frame simultaneously.

Interface board of the present invention can adopt the power supply power supply in computer exchange/direct current (AC/DC) power pack, under the situation of conditions permit, also can be powered to interface board by the PCI slot by computer motherboard.

Two telephone line interfaces are arranged on the plug-in card, and are connected with networking telephone processing module, can realize by a select switch:

(1) when ordinary telephone line has call placement to come in, select switch can this calling of auto by pass, directly receive on the telephone set by a telephone interface (RJ11), and without the processing of networking telephone processing module.

(2) will call out local call as the user, select switch can be called out by ordinary telephone line and connect local called subscriber.Also can be provided with all from voip network exhalation (but the general fewer employing of this situation).

(3) when the customer call voip user, can pluck telephone set equally, call out by IP network through the network diagram call processing module.

Said keyboard: contain a computer keyboard and an ordinary telephone set.Also have microphone, LCDs, loud speaker and phone movement on the keyboard.Numeric keypad district on the keyboard both can serve as common keyboard and use, again can be as the keyboard of telephone set.

The invention has the beneficial effects as follows,, therefore, can realize that (VoIP) network telephone, ordinary telephone set and computer organically combine because interface board of the present invention couples together computer and ordinary telephone set.Can effectively utilize resource, reduce taking up room of equipment, the convenient use.Simultaneously, the present invention will promote the further fusion of computer, telephone network and VoIP net, promote the development of new technology.Components and parts of the present invention are general in the industry products, and selectable leeway is very big.It does not change the computer present interfaces simultaneously, need not develop again, and is whole with low cost, and easy and simple to handle, and the call function of telephone set still can use when not moving computer.So have the automatic route selection function, the AUTONET automatic network function of exchange.Higher dissemination is arranged.Being mainly used in enterprises and institutions' office and family uses.Can develop more applications and service future on this hardware foundation, to satisfy users' demand.
