Abstract
The utility model relates to a computer network data conversion technology, in particular, an E1/ETH protocol data conversion unit. According to the network management enhanced E1/ETH protocol converter, a master processing module is electrically connected to an E1 processing unit, an SDRAM memory unit, an Ethernet processing unit, a network management unit and an LED indication unit. The master processing module comprises an FPGA chip unit externally connected to a clock circuit unit and a reset circuit unit. The master processing module is also electrically connected to an alarm and state processing module, which is used for prompting and processing an E1 signal loss alarm, a coding violation alarm, a GFP packaging out of frame alarm, an Ethernet error alarm, and the like. The network management enhanced E1/ETH protocol converter completes data exchange, combination and share of an E1/Ethernet, and realizes network management information transmission under framing working mode and non-framing working mode of an E1 bridge.
Description
Technical field
The utility model relates to the computer network data switch technology, particularly a kind of E1/ Ethernet (ETH) protocol data converting unit.
Background technology
Computer nowadays and network development thereof are more and more faster; This takes place to get in touch widely, is connected, exchanges, shares and associating through regular meeting down to the application of various forms network system for various computer programming languages, operating system, database, specialized management system, like this must changing between the data pattern that needs are shared.
Therefore, a Chinese patent publication number being arranged is that the E1/ Ethernet Date Conversion Unit of CN201403101 is suggested and realizes this conversion.Its technical scheme that adopts is: connect webmaster control unit, E1 interface circuit unit, too network interface circuit unit, LED indicating member, DIP control unit, SDRAM storage element, clock and reset circuit unit respectively by Main Processor Unit.Power conversion unit connects Main Processor Unit, webmaster control unit, E1 interface circuit unit, too network interface circuit unit, LED indicating member, DIP control unit, SDRAM storage element, clock and reset circuit unit respectively.
The weak point that the technical scheme of this E1/ Ethernet Date Conversion Unit exists is: existing E1 bridge mode of operation has: G.704 framing and non-framing.G.704 frame structure is a kind of multi-frame structure, and 16 single frames constitute 1 multi-frame.In each single frames, be divided into 32 time slots again.Wherein the TS0 time slot is used for transmission network management information, and TS1～TS31 is used for transmitting user data.Under the unframed mode, TS0～TS31 is used for transmitting user data, and network management information can't transmit.
Summary of the invention
The utility model technical problem to be solved is: a kind of webmaster enhancement mode E1/ETH protocol converter is provided; With completion E1/ Ethernet exchanges data, associating and shared, and realize that simultaneously E1 bridge mode of operation can both realize the transmission of network management information under framing and unframed mode.
The technical scheme of the utility model is:
Webmaster enhancement mode E1/ETH protocol converter is electrically connected at E1 processing unit, SDRAM memory unit, Ethernet processing unit, network management unit and LED indicating member respectively by main processing block.
Further, described main processing block is fpga chip unit external clock circuit unit and reset circuit unit.
Further, described main processing block can also electrically connect an alarm and state processing module.This alarm and state processing module are used for prompting processing E1 loss of signal alarm and coded violation, CV is alarmed, GFP encapsulated frame step-out is alarmed, Ethernet is made mistakes warning information such as alarm.
Home Network tube enhancement type E1/ETH protocol converter also is provided with a power conversion unit, is connected to each above-mentioned module, the power end of element circuit, so that operating current to be provided.
The utility model adopts as above technical scheme, and the technique effect that has is:
1. accomplish E1/ Ethernet exchanges data, associating and shared, realize the conversion of E1 to Ethernet.Adopt the telecommunications access device of large-scale F PGA Development and Production.Make full use of the existing e1 resource of communication network, the access of Ethernet is provided for group's big customer's private network.Have complete warning information and performance statistics, support online error code testing function, monitoring is provided in real time the quality of circuit;
2. realize simultaneously that E1 bridge mode of operation can both realize the transmission of network management information under framing and unframed mode.Solved framed mode fixedly open up down the TS0 time slot be used for webmaster to the waste of resource and unframed mode time can't webmaster shortcoming; Management frames is carried out the HDLC encapsulation; With the shared TS0 of the HDLC frame～TS31 passage that transmits Ethernet data, but framing and unframed mode webmaster all.
Description of drawings
Fig. 1 is that the modular unit of the utility model connects block diagram.
Embodiment
Combine accompanying drawing and embodiment that the present invention is further specified at present.
Consult shown in Figure 1ly, the webmaster enhancement mode E1/ETH protocol converter of the utility model is electrically connected at E1 processing unit 2, SDRAM memory unit 3, Ethernet processing unit 4, network management unit 5 and LED indicating member 6 respectively by main processing block 1.
Further, described main processing block 1 is fpga chip unit external clock circuit unit and reset circuit unit.
Further, described main processing block 1 can also electrically connect an alarm and state processing module 7.This alarm and state processing module 7 are used for prompting processing E1 loss of signal alarm and coded violation, CV is alarmed, GFP encapsulated frame step-out is alarmed, Ethernet is made mistakes warning information such as alarm.
Although specifically show and introduced the present invention in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the present invention that do not break away from appended claims and limited; Can make various variations to the present invention in form with on the details, be protection scope of the present invention.
