Description
Technical field
The present invention relates to voice and data network technical field in the mechanics of communication, particularly relate to integrated voice and data network system with isolating line.
Background technology
(1) when multiple data treatment system and/or calculation element and LAN (LAN) binding, each device all has one only one the network address, to allow data be sent to predetermined terminating machine.When LAN and other Wide Area Network (WAN) when being connected, for example internet (Internet), each LAN then also must give an internet communication protocol address (IPAddress) under identical situation, these two systems all use identical unified identification form (uniformidentification format), this form is one by four groups of numbers of 0 to 255, between number with " fullstop " separately.Therefore this number is referred to as " point-number " indicate.
Each LAN is also simultaneously designated to have one or more nodes (nodes) to be " Gateway ", so that each LAN carries out communication via WAN and other LAN.So remaining terminating machine also must be noticed the Gateway network address among the LAN in LAN, could carry out communication via Gateway and other LAN like this.
In addition, for distinguish in a LAN and a plurality of LAN individually carry out the communication of WAN and LAN, in being to use a subnet mask (SubNet Mask) to separate IP address details in the message.Though this subnet mask system is with binary carry algebraically (binary algebra) " 0 " reach " 1 " as the basis, this shielding also be with " point-number " indicate.
Moreover special terminating machine or node in LAN or WAN are keeping database, and this database can become letter-digital name with the IP address translation, or general-letter-number is translated into the IP address.A kind of DNS (Domain Name Server) that is referred to as, this is very important, because general user still is accustomed to using the name that acquires a special sense to call special terminating machine, rather than with point-digital IP address, because the IP address is comparatively accurate to the data treatment system, if a terminating machine does not have this equipment, then must store an IP address at DNS in advance, so that running normally, generally in LAN, DNS is promptly as Gateway, because logically DNS has this ability most as Gateway, even if it does not have database, it also can utilize the virtual network framework to enter DNS among the WAN.
In gross, this four groups of points-number numeral, general industry is referred to as TCP/IP (transmission control protocol/internet protocol) characteristic, is unusual important parameters for the normal operation of data W AN and LAN.But for the user, they but are not have assorted one meaning.
Traditionally, the setting of data W AN and LAN and to keep be by carrying out through the professional of special training, its academic title is network engineers or network manager, they handle the various characteristics of TCP/IP every day.IP address node is that (this class of Network Solutionwww.netwosol.com is organized and coordinated by the network solution, but, the end user of data equipment does not but have assorted one to understand to these network parameters, and for general user, they are the object of a mystery only.
In traditional speech communication, also can find similar situation, telephone operator has specified a Directory Number (generally being referred to as telephone number) to each user, to allow the user at public exchange telephone network (PSTN, Public Switched Telephone Network) carries out telephonic communication in, for large-scale user, another regional pbx switch then can be installed, for example Private Branch eXchange (PBX) or Private Automatic BrancheXchange (PABX), each company personnel then is endowed an extension (ExtensionNumber), so phone can directly be transferred on the public table of distinguishing of employee.
The PSTN service is normally undertaken by the trained employee of telephone operator, the full-time then nationwide DNs of operator that organizes under FCC (FederalCommunications Commision) supervision.The PBX of a company (or PABX) is then being keeped in repair by a Telecom Manager traditionally, and their responsibility has comprised specifies and keep one group of extension that does not have entanglement.
Because PBX and lan technology reach its maturity, these equipment can lower price offer small enterprise and family, (the SOHO so revive, Small Office Home Office) then becomes the emerging market of these products, but the installation of these equipment and maintenance still need the personnel of suitable technology to carry out.
A job wherein promptly is to set an IP address in LAN, reach and in PBX, set extension, and make a user before can using LAN or PBX smoothly, must need a unique cognizance code, if these codes are not managed, just whole system can be not normal at an easy rate.
To be this series products entering one of maximum resistance that the family market of reviving run into for this, and these clients can't employ a network or telephone engineering teacher comes management system, and these families that revive will spend so high cost for large enterprises and keep this system and frightened.
The setting of the extension in PBX is also so difficult not as set the IP address at LAN, because extension is to be disclosed in the register of enterprise, and will use every day.The number of extension set can link up with employee's name at an easy rate, but for the IP position in the data handling system, for majority, is remote irrelevant.
United States Patent (USP) the 5th, 596, disclosed a kind of Distributed PABX for No. 631, and United States Patent (USP) the 5th, 696, disclosed a kind of HomePNA (Home Phone Network Alliance) for No. 790, the two all is a modular construction, and colleague-right-colleague's framework, and make this product more approaching the user, because, be to increase severely with day for the demand of the effective communication of voice and data.
These two kinds of products all have identical module in the place of required service, and module is connected telephone wire with traditional list with intermodule system, do not have central authorities or main unit in this cover system.These modules are come communication each other according to its cognizance code that is set, these basic characteristics can allow the family that revives increase at an easy rate, move or delete another module, moreover, not normal module can be replaced by another more unessential module soon, so reduced the impact that enterprise is subjected to, so network engineers or telephone engineering's teacher needs just can have been avoided.
The DPABX control module is designated to be designed to " user can set ID switch switch (subscriber settable ID switches), and this switch switch allows that a user gives an extension that control module is new by changing its ID switch switch to new combination.Being chosen the validity of extension can confirm by dialing this new extension at an easy rate, for example, new selected number repeats as if the number with other, in network another phone just can be subjected to this logical test dial and warn, so just will select another sets of numbers to give control module.Such step will repeat always, until till the extension that does not have to repeat, owing to be equipped with this cover numerical selection system, the market prospects of this cover system are greatly good.
From another perspective, HomePNA transducer (Adapters) is derived out by its original data LAN.Can have influence in the parameter of its operation at other, " the IP address " setting then still belong to the specialty complex work.
In order to make " the IP address " setting in the LAN field become comparatively simple, there is a kind of technology to carry out a period of time, this technology is called as DHCP (Dynamic HostConfiguration Protocol, DynamicHost framework association stipulates), this technology can allow the Gateway of LAN automatically set one group of numerical value with as the IP address to the client.So this technology has alleviated network engineers' burden because network engineers must look after the operation of LAN at any time because the DHCP program is at random, by the specified IP address of Gateway then become more do not allow the prediction.Also become more difficult so fix a breakdown, for example, a new terminating machine has been installed in LAN, this terminating machine may be set to the IP address of the terminating machine of the present use of just starting shooting of another among the LAN, but when two terminating machines activate simultaneously, just can go wrong, for fear of this unforeseen situation, some network engineers would rather be turned off the function of DHCP.
But, what is interesting is very much and can notice, in aforesaid four groups of point-digital parameters, all each data processing equipments in LAN, all only need allow the 4th number in the own IP address be a variable, promptly can make the usefulness of special identification of this variable.
Other number can be a fixed code (in first three number of IP address and all son shieldings) first, the kind that is decided by the LAN that terminating machine belongs to, or its " Gateway " reaches " DNS " it " IP address " in same LAN, these numerical value all are predefined, because these nodes must just be finished setting at the beginning.Therefore, the work of a data processing equipment of identification just can be simplified at 0 to 255 selects a number, and this number remains unique at LAN, and through this simplification, the setting work of TCP/IP is with easier grasp and processing.

Wherein, Fig. 1 describes out one and revives in family's environment, the basic framework that a plurality of work stations link via telephone wire 100, and this phone linear system is extended by PSTN 101.As the personage who knows this skill understands, and telephone wire 100 is divided skill easily, transfers or extends to all devices of work station, as long as keep telephone wire unobstructed.
For instance, work station can be respectively by data processing equipment 110,120 ..., 130, and exchange equipment 111,121 ..., 131 formations.
Data processing equipment 110,120 ..., 130 utilize telephone wire 100 respectively, via data connector 113,123 ..., 133, and HomePNA adapter 112,122 ..., 132 interconnection, and then constituted data communication LAN 199.HomePNA adapter 112,122 ..., 132 is United States Patent (USP) the 5th, 696, No. 790 commercially produced product.Data link 113,123 ..., 133, then be a kind of of normal line connector, USB (Universal Serial Bus) for example, this connector is the connector that personal computer is used always.So this specification no longer elaborates.
Exchange equipment 111,121 ... 131 utilize DPABX controller 114 respectively, 124 ..., 134 are connected to telephone wire 100, and then the DPABX network of formation speech communication, DPABX controller 114,124 ..., 134 is United States Patent (USP) the 5th, 596, No. 631 commercially produced product is so this specification no longer elaborates.
In order to allow speech network normally operate, each DPABX controller 114,124, ..., 134 all by " the ID switch " (United States Patent (USP) the 5th, 596, the Box 241 of Fig. 5 of No. 631) give an extension, as in any PABX, extension can be any length easily, as long as in the system held unanimity, and each extension set all is unique extension, industry is generally called this convention " code scheme ", for at recognition data treatment facility 110,120 ..., 130 meet this convention (from the number of 0-255), and avoid by " 0 " beginning, DPABX controller 114,124, ..., at random give extension 234,155 for 134 ..., 187, below will go through.
Modulator-demodulator 115 has multiple enforcement aspect, and as shown in Figure 1, modulator-demodulator 115 is a basic model analog modem, for example transmission speed be 56Kbps V.90.Data connector 116 then is a standard sequence cable (RS-232), generally is referred to as the external analog modem of personal computer, and personal computer system enters interference networks 102 by PSTN 101 via data connector 104 by telephone wire 100.
Modulator-demodulator 115 can be a DSL (Digital Subscriber Line) modulator-demodulator, and it also can use on standard phone line.But in order to support the high speed data transfer from DSL, data connector 116 can be Ethernet molded lines cable.
Modulator-demodulator 115 can be by in other several the technology a kind of, for example coaxial cable, radio, optical fiber or satellite.If used aforesaid a kind of, then 102 connection can no longer be a telephone wire 102 in modulator-demodulator 115 and internet, 103 in dotted line has been described this transfer of data, in these cases, higher transmission speed can be arranged, and data connector 116 can be Ethernet molded lines cable or product at the same level.
Be noted that these various execution modes in the Gateway internet can't have influence on work station identification main body of the present invention, illustrate that at this they are intactly to represent the bulking property of network system.
Because HomePNA adapter 112,122 ..., 132 can be structured in data processing equipment 110,120 respectively in entity ground ..., in 130, in being to use more popular data terminal set (dataterminal) to describe this combination.In addition, modulator-demodulator 115 also can be structured in the data processing equipment 110, so when using Gateway one speech, also modulator-demodulator 115 may be included.
Same, exchange equipment 111,121 ..., 131 also can be structured in DPABX controller 114,124 respectively ..., in 134, in order to simplify word in the following discussion, will use " the voice terminal machine " this combination described.
In addition, the rectangular-shaped frame 119,129 that dotted line is drawn as ..., 139, then comprise a data terminating machine and a voice terminal machine respectively, and then formed work station Gateway respectively, CLIENT1 ..., CLIENTn.
Fig. 2 has disclosed calcspar of the present invention, is to reach by the subsystem interconnection of revising in the work station, and for example, Fig. 2 duplicates for Fig. 1 CLIENT1's 129, but except following:
Interface (InterFace I/F) circuit box 200 has been added in the DPABX controller 124, so that use the data on ID switch switch 241 holding wires 242.
Such design allows that data terminal set 120 has the existing numerical value of the ID of reading switch switch 241 " 155 ".Yet data connector 225 and 226 combination meetings are all kept the function that former cause data connector 123 is provided by I/F 200.
By above design, can be clear that data terminal set 120 is used for the extension that can use as the IP address of specific identification in the DPABX system.Because at United States Patent (USP) the 5th, 596, disclosed extension in No. 631 and be and can set and confirm by the user, so the IP address of data terminal set 120 characteristic that convenient user uses of also having had simultaneously.
Fig. 3 lists the parameter of data terminal set 120, with example as TCP/IP character, below at length disclose Fig. 1 work station be those data of definition how:
In IP address 301, Gateway 303, and the preceding trigram (192.168.0) of DNS 304 is the employed standard digital of LANs.
Last sign indicating number of IP address 301 " 155 " 305 items obtain according to the disclosed ID switch of Fig. 2 switch 241.
Because numeral " 255 " equal in the binary carry system " 11111111 " (eight 1), code with subnet mask 302 " 255.255.255.0 " 306 with the code of IP address 301 " 192.168.0.155 " carry out a logic " OR " computing, play except the first three groups code, and kept last sign indicating number.And by " 255.255.255.155 " the unique significant numeral of coming that derived will be " 155 ", should numeral then be unique to CLIENT1 129.Should numeral then be with DPABX in extension set " 155 " identical, promptly realized so in the work station that constitutes by voice and data terminal set, obtain comprehensive address identification system.
In Gateway address 307 and the numerical value of dns address 308 be assigned to Gateway 119 simultaneously, and have the work station identification number " 234 ", as with the 4th sets of numbers specified, in Gateway IP address 307 " 234 ", then preestablish, so that in Gateway 119, realize identical subsystem interconnect design.
During the work station running of aforementioned exposure, can be read by area data terminating machine 120 by ID switch switch 241 defined numerical value, to set its own IP address 301, this setting can be carried out under different situations.
1) when data processing equipment is installed network software;
2) opening or again during the turn-on data treatment facility;
3) before carrying out a dynamic communication;
Because the identification of the work station in LAN must be unique, simple software can be installed in all data terminal sets, to scan to confirm not have the IP address of repetition in whole LAN.When detecting the IP address of repetition, have caution and be activated, to allow the user solve the problem that repeat the IP address.Because IP address 301 is controlled by the ID switch switch 241 of voice terminal machine, inspect company personnel's register apace or dial a logical intercommunication phone, can address this problem.ID switch switch 241 is set to one uses combination to revise step, can allow that data terminal carries out the login operation (log-on) of LAN.
Fig. 4 has described the content of lock road 119 subsystems ordering in more detail.Circuitry lines 100 to PSTN101 is in the lower left corner that has moved on to lock road 119 continuously on lock road 119.100 of part telephone wires between PSTN 101 and social connections 119 are endowed new numbering 402, and therefore, all must pass through lock road 119 between the signal communicating of PSTN and the residue telephone wire 100 in LAN 199 and carry out.Simultaneously, the online some that becomes telephone wire 100 in the inside on lock road 119, rather than the former branch wiring that arrives first telephone wire 100, next, 111 of DPABX 114 and the exchange equipment that match have been done configuration again up along telephone wire 100, therefore, along telephone wire 100 low pass filter 401 has been installed then between modulator-demodulator 115 and HomePNA 112.
The function of low pass filter 401 is to allow traditional analog telephone service signals at audiorange (0-4.5KHz) be not subjected to anyly to pass through intrusively, but stop that those originally will be via LAN 199 and on lock road 119 and the high-frequency signal of 101 transmission of PSTN, low-frequency filter 401 is basic filter circuits of knowing, so this specification is no longer done and explained.
The HomePNA network signal is along lock road 119, through client 129, client 139..., uses greatly about 5 along telephone wire 100.5MHz to 9.Frequency range between 5MHz transmits, in addition, and along telephone wire 402 and, then taken 25KHz to 4 as xDSL (the multi-form DSL form that DigitalSubscriber Line, " x " express possibility) in the broadband signal of 119 of PSTN 101 and social connections.The frequency range of 5MHz.
HomePNA and xDSL signal are then done optimization according to their final environmental demand respectively and are handled, that is to say, HomePNA is short distance signal transmission within doors, characteristics are taps optionally, xDSL then is the long-distance signal communication of point-to-point, therefore to do to separate each other and cause influence undeservedly in order to avoid they have entered the net territory that should not advance, even cause the phase mutual interference, reduce the transmission quality of signal.
In addition, lock road 119 still provides and has optionally separated semiotic function, and promptly can to find out easily be that the equipment circuit of that tame phone company is out of joint actually on the lock road, and it is precious disconnected and repair therefore can to carry out problem apace.By low-frequency filter 401 is placed between telephone wire 100 and 402, the audio signal that comes from traditional telephone company just can pass through insusceptibly.The HomePNA signal then cannot pass through telephone wire 100, and the xDSL signal then transmits via telephone wire 402.In the case, 119 on lock road provides between WAN Communications service and PSTN 101 and the LAN system that is made of client 129,139.. and has isolated the function of selecting.
Fig. 5 and Fig. 2 difference are that Fig. 5 has increased an extra holding wire 501, simultaneously enclosed the client 129 that annotates by again by dotted line " coiling " to give the subsystem of minority with its restriction, major advantage of this youngest's processing is that data processing equipment 120 and holding wire 225 thereof just become client 129 external equipment.
Newly-increased holding wire 501 provides the DPABX main circuit to the binding of HomePNA signal via I/F200.So its detailed structure demonstrates client 129 can carry out the speech communication transmission simultaneously as the traditional copper stamen telephone wire that uses the DPABX technology terminating machine, also can use as the wideband equipment of HomePNA adapter 122.Foundation by these functions, client 129 can be under the situation that does not have data processing equipment 120, this has been a data terminating machine in the HomePNA network, framework of the present invention demonstrates simulation and digital network system can finish by voice-transmission system individually, because it is more natural and easier to be operated and use for the modern that voice system compared to data handling system 120, seems.After all, the data processing equipment 120 that is connected to system by circuit 225 can become a newly-increased data processing network function at an easy rate, and is fully to be provided by 129 of narrowly-defined clients.
The present invention can have different execution modes, for example, if need not actual switch switch set the extension of voice terminal, also can utilize the button on the telephone set to select those numbers, and the number that stores also can utilize the display unit in the system of being installed in, and for example LCD (LCD) or synthetic speech are confirmed.
In order to simplify, in the present invention, used in the drawings by 100 to 255 three bit digital, so 156 kinds of selections are just arranged, for less system, two-bit digital code can so also have 90 kinds of selections by 10 to 99.For the microminiature applying unit, nuclear family for example also can use the single number (1-9) of 9 kinds of selections, in all selections, " 0 " all keep and give exchange.
For large enterprise's body, also can use four or five-digit number sign indicating number, former sign indicating numbers of some of them can use identical numeral as beginning.So do not need with above-mentioned former piling up in the IP address, on the other hand, there are enough spaces to allow and set the IP address, promptly the trigram in the IP address (for example " 0 ") can be used for amplification, to contain the extension among the large-scale DPABX, the coding system and the aforementioned revealer that handle amplification are closely similar.
For will be for simplicity, the present invention system to be being independent of the data handling system in the work station, the HomePNA transducer, and the DPABX controller, the telephone exchange system, modulator-demodulator waits and illustrates.Because each communication module in work station all is to be connected to identical telephone wire, very naturally also all devices can be assembled under the same framework, as long as and stay next plug to insert telephone wire 100, and other module just can not seen by the outside, its different function then can be assigned to different subsystems again, to do more economical and to effectively utilize, for example, synthetic address even can utilize the keyboard of data processing equipment to set, and from screen acquisition affirmation, be noted that this still belongs to scope of the present invention.
All use in the present invention via the speech network of DPABX telephone system and via the digital data network of HomePNA, the two can be considered the separated technology that is used in the different types communication.Because the fast development of digital technology, digital communication technology can the carry speech technology.In fact, video signal can also carry via digital system.So, the consumer has more communication mode, VoIP (Voice over Internet Protocal) for example, VoDSL (Voice over DigitalSubscriber Line) or the like, for example, the excessive data technology based on the extra telecommunication channel of data technique can enter via the work station in the aforementioned exposure framework; But the speech communication between the mankind is via analog voice, and therefore, in order to simplify the man machine interface, DPABX can do the basis in foundation and the continuous this multiaspect of dimension unceasingly in communication system.
Exposure of the present invention is with traditional telephone wire, as LAN and DPABX system is the basis, must be noted that enforcement of the present invention is not restricted to any transmission communication technology, essential ideas of the present invention is to utilize a kind of user's of convenience method to come the cognizance code of setting terminal machine, and this notion also can be applied to other network, for example coaxial cable, optical fiber, radio or satellite communication, moreover my invention also can be applied in the work station that uses different pieces of information media and voice transfer.Comprehensive identification code of the present invention is applied to all devices in the same workplace, be with network in the multiple transmission medium that uses have nothing to do.
In disclosed LAN, do not need the work station of DPABX ability can dispose the IP address of suggestion usefulness " degenerate or subset " version, as long as dispose ID switch switch 241 equipment, so, employed IP address number just can be outside the code scheme of DPABX, for example, and the LAN that in all figure, discloses, what all comprised 1 to 99 all can reserve in this purpose, because DPABX system adopts the tri-bit encoding plan.
The inferior combination of these numerals can be applied to other device, for example printer or other electronic installation, the cognizance code of these devices can not change after setting mostly, certainly, the selection of this class IP address digit must be controlled and tubulation modestly, to avoid and repeat to cause entanglement, this puts then extraordinary image network engineers conventional operation to be processed.
Fig. 4 then upgrades at traditional isolating line, and this separates linear system and uses as analog of telephone line, also can be applied in digital wideband service.This is because all services on telephone wire 402, telephone wire 100 also can provide, estimate that the signal that will occur then can not appear on other the line, in the transmission technology that the present invention is applied to other existing WAN and LAN, the flexibility that framework of the present invention then provides bigger mixing to use in selectable technology for the consumer.
Fig. 5 has set up a new service isolating line simultaneously, and then in LAN, speech ciphering equipment and data equipment separated and come, therefore, simulation and digital device in network, have been set up via voice service in view of client 129, data processing equipment 120 is newly-increased devices for client 129, so holding wire 225 representatives are based on the network of voice and the isolating line of additional data applications equipment room thereof, this is an important problem, because as long as any abnormality has appearred in data processing equipment, these complicated data processing equipments can just remove it by interrupt interface line 225 very simply, but then can independently continue running insusceptibly by the voice service that client 129 is provided.
The LAN terminating machine framework of aforementioned exposure has solved the data-centered problem that network system ran into.That is to say, at voice still is that basic Communications service and relevant device thereof still is under the network access arrangement, the present invention's framework can directly be controlled the communication and traffic that enters in the LAN, particularly cannot stand the speech sound signal of signal transmission delay can control by the control device in each client 129 of the interior figure of building in five exposure easily, voice are transmitted with prepreerence order, build in the data signals of being sent by data processing equipment 120 then is temporarily stored in simply in the buffer device in the I/F200.Be transmitted as design aim based on all wideband network systems with mass data, therefore the frequency range of this class is also wide far beyond the frequency range of the speech sound signal in the consolidated network system, therefore can avoid taking place communication fully and block hysteresis phenomenon, can suspend the data communication transmission at any time because the operating rule of system is given client 129, it is hereby ensured smooth-going voice transfer.This communications protocol can be eliminated and use the subject matter of transfer of data as QoS (service quality) in the speech sound signal transmission.
Expand this principle other in the network and use by pushing away, so just service item that can all are known is preferentially made tabulation according to it, for example, the order of priority of saving alarm from damage is more taller than voice.Then the boundary is in voice and data signals for the order of priority of video signal, and after data-signal, we can have Appliance Telemetry and Command to use.At last, those low data transmission rates, it is not the equipment of critical function that use seldom reaches, for example Utility Meter management then can be classified least important project as.
Same, by at the attachment device of data terminal set as voice terminal, the consumer can use diversified data processing equipment in each zone, and its regular change has not been a problem just on network.
The present invention is special assemblies at the low pass filter 401 that Fig. 4 discloses, because all signals all are to transmit under different frequencies by same physical media (paired copper cash), in other WAN transmits to lan signal, the employed transmission media of WAN and LAN is all different, therefore, the isolation that is provided by low pass filter 401 just can fully have been reached.
(3) though in sum the present invention illustrate at special embodiment, must be appreciated that under without departing from the spirit or scope of the invention, the personage who knows this skill can have various variation and correction, right these change correction and ought to be included in the claim of the present invention, sincerely please examine, and pray the gift quasi patent.
