A modular switch system based on high-speed serial network features that the high-speed serial data lines are used to connect the host connector to various function modules, and various function modules can respectively become the different nodes of Intranet for implementing bidirection signal transmission between the nodes and host connector via high-speed serial data lines. Each function module has its interface controller and microprocessor. Its advantages are high data processing and transmission speed, hot attach and detach, and high extensibility.
Description
Technical field
The invention relates to a kind of modular switch system, refer to that especially a kind of convenience expands the periphery and the tool transmission speed is fast, the high LAN formula switch system that is not subject to advantages such as body appearance that reaches of usefulness based on high-speed serial network.
Background technology
Because making rapid progress of science and technology, development of electronic technology begins in conjunction with computer technology, thus present switch mostly with computer as central control unit, and can utilize the work of stored-program control exchange.
From the above, the combination of communication, computer and network becomes common practice, thereby produces the demand that compuphone is integrated (CTI).Other is because of the continuous amplification of transmitting bandwidth, generally only make a phone call, the switch of functions such as voice mail, Auto Attendant applies and uses, be the network switch (IPBX) that impels manufacturer progressively to develop conformability, it combines automatic traffic and distributes (ACD), speech polling (IVD), messages in mailbox (VMS), fax to handle (FOD), synchronization functions such as (Recording).
Again, digital exchange system can not only reach exchange of speech, more will the march toward Exchange Service of non-voice, because the opening of fixed network, the arriving of wideband, PBX must be towards the service function development of diversification after day, in overall development, compuphone is integrated CTI, asynchronous transmission switching technology ATM or the like, to impel telecom communication and transfer of data, image processing, variation such as network is integrated, and similarly is intelligent network (Intelligent Network), video conference (Video Conference), the networking telephone (IP Telephony), global function telephone traffic center (Call Center), intelligent interactive voice service (Interactive Voice) or the like function will be popularized gradually.
From the above, research and development achievement that switch system is present and demand present situation, because it constantly expands on function, so must be an extendible form on framework, shown in the 4th figure, it is a kind of known switch system, this switch is to establish an exchanger host plate 70 in internal body, exchanger host plate 70 is provided with CPU71, with as the control maincenter, exchanger host plate 70 is to see through the bus function adapter different with interior ply-yarn drill 72, outer ply-yarn drill 73 and sound recorded book 74 etc. with the slot (SOCKET) of specific standard/quantity to be connected again.And be the transmission and the control of every function of reaching data, each function adapter has the bus of many group difference in functionalitys respectively, as data bus (Data bus), address bus (Address bus), control bus (Control bus) and analog signal bus (Analog bus) etc., link for bus corresponding on the switch.
And for example shown in the 5th figure, it is another kind of existing extendible switch form, it is to be provided with the operation processing unit 71 of CPU, also be made into an adapter form, and mode of connection between exchanger host plate 70 and aforementioned various adapter are similar, are to see through data/address bus (Data bus), address bus (Address bus), control bus (Control bus) and analog signal bus (Analog bus) etc. to constitute on line.
Yet, no matter exchanger host plate 70 is with built-in or outside adapter form operation processing unit to be set, communication between all functions adapter and CPU, in full reportedly defeated and function control etc. all is to see through set bus to carry out the following problem of promptly deriving under this situation:
Extendibility limited, influence execution speed: because exchanger host plate 70 only is provided with fixed qty/rule
The bus slot of lattice, its extendibility promptly is subject to the quantity of this slot, even and have enough slots can
For using, every increase by one function adapter is promptly represented the raising of bus load, and overall work usefulness also will
Reduce relatively.
2. hot plug difficulty: under the form that interface expands, make heat in 70 pairs of functional modules of exchanger host plate
Plug very difficult.
3. expand the cost height: exchanger host plate 70 must be prepared enough bus slots for the usefulness that expands, but
More bus slot not only makes installation exercise more become complicated, simultaneously cost is improved relatively.
4. appearance is fixed: be subject to the setting of bus slot, switch is also restricted on the appearance forrns of casing,
Variation polynary or that amplitude is bigger can't be arranged.
From the above, still there are problems in existing pbx switch for extended function under conventional architectures, remains further to be discussed, and seeks feasible solution.
Summary of the invention
