together by four pairs of lines to reduce crosstalk and background noise. At the same time, only 1, 2 and 3, 64 lines of twisted pair are used in the T568A standard and the T568B standard, where 1, 2 are used for sending, 3, 6 is used for reception, and 1, 2 must come from a winding pair, 3, 6 must come from a revolve pair. Only in this way can the maximum avoid crosstalk and ensure data transmission. Not according to the correct standard (T586A, t58

The following are the reasons and solutions for the slow speed of the network: First, the network itself problem The destination Web site you want to connect to is on a server with insufficient bandwidth or too much load. The processing method is very simple, please change the time period to go up again or change a target website. Second, network cable problems caused by slow speed We know that twisted-pair wires are tightly twisted and together by four pairs of lines to reduce crosstalk and

The following are the problems that lead to slow network, as well as some common network problems to solve, in this collation to the users. (Internet collection) First, the network itself problem The destination Web site you want to connect to is on a server with insufficient bandwidth or too much load. The processing method is very simple, please change the time period to go up again or change a target website. Second, network cable problems caused by slow speed We know that twisted

Computer network failure is unavoidable. Network fault diagnosis is an important work of network management. Generally when the network occurs information is not available, can not browse the Web, and other connectivity failures, the phenomenon is relatively clear, easy to observe and locate the fault point, such a fault is not difficult to solve. But the most troubling thing is that the internet is a pass, but the network speed slows down. When confronted with such "soft faults" for the first

, and then use ping to check, if the general rule of failure to solve. It is also possible that the line away from the network Management center of the end of the plug loose, you need to check the terminal equipment connection status. If the socket is not a problem, you can use the network cable test equipment for path testing, found that the problem should be replaced by a network cable. Another common physical failure is the network plug mistakenly connected. This situation is often caused by

Huawei Optical Fiber switches improve performance through the optical fiber expansion module. Colleagues are responsible for the interconnection of Huawei Optical Fiber switches in the company. This is a very large project. Outsiders will be confused. The following are just some of the issues with Huawei Optical Fiber switches, but for beginners who do not know anything, it is enough for you to have a new understanding of the performance configuration of the Huawei optical fiber switch. ◆ Linksy

Optical fiber Broadband Router Function AnalysisType: HFR-1330N-1-1-1 fiber Broadband Router, wan port to fiber interface, no photoelectric conversion, suitable for small office network www.2cto.com main specifications/special functions: HFR-1330 Optical Fiber router is a high-performance router designed for small and medium-sized enterprise network connection, can provide Four 10/100 BASE-TX g RJ45 port and a 100BASE-FX SFP g WAN optical port, flexib

and remove the wall from the ceiling to each information point. All information points are in a dark box. All integrated wiring products use over five categories of yuefeng cabling, that is, cat5e twisted pair wires, cat5e information sockets, cat5e jumpers, cat5e modules, etc., to provide M data transmission speed, it meets the needs of high-speed Ethernet and ATM network data transmission, thus laying the foundation for high-speed data transmission. The following describes the subsystems of t

The testing environment is 3745 plus a support, vwic-2mft-g703 nm-2w, for this module and card, all ios versions of 37 are supported. Test ring cable used: a common straight-through twisted pair wire, rj45 crystal head rj45 and Micron 48 difference to achieve the line order of which is different), a model for the cab-adpt-75-120 cable, see the figure below for details. First start the router, nm-2w en light

. However, if the indicator light is not on, this interface cannot be used. However, this interface is the only hope. Otherwise, we can only transmit the 41MB IOS using xmodem, I am afraid the transmission time is prohibitive.TIPS:The speed of using XMODEM to transmit IOS is a headache. I used XMODEM to transmit a 2950 switch IOS, with a total capacity of about 2 MB. It took two hours. At this speed, it may take up to 30 hours for 41 MB.Since the use of XMODEM transmission IOS is not realistic,

This article uses the Cisco 2509 Terminal Server to log on to other machines. how to configure the server? The following article describes the configuration process in detail and provides configuration commands. Use Cisco router reverse Telnet for Terminal Server If we have multiple routers for experiment, it will be very troublesome to configure one Router Based on the control line. Therefore, we need to configure a terminal server to log on to other machines, the procedure is as follows: In

. For more specific application, you can refer to the following article, this article is to study the FWA-3140 as an example, do an application, address:Http://www.panabit.com/document/panabit_bypass.html Iii. Principle Analysis of Bypass implementation The above briefly describes the Bypass control method. The following briefly describes the working principle of Bypass, mainly from the hardware and software aspects. The research object of FWA-3140 series products of inghua 1. hardware layer. In

? I. zoon's meaning and division principles ???? The function of Zoon in an optical fiber storage switch is similar to that of an Ethernet switch VLAN. It is mainly used to divide multiple logical zones in a switch to prevent storage connections of different applications from initiating broadcast packets, improves the utilization of Optical Fiber switches. ???? In principle, zoon must have at least two nodes, which can be based on the vswitch port or the WWN Number of the Optical Fiber adapter (

different, it is very important to find out the role of each port. The vswitch mainly includes a console control port used to configure Internet access parameters, two RJ45 ports connected to the external network, and four RJ45 ports connected to the internal network, both the Intranet and Internet ports belong to the 10/100 Mbit/s adaptive port. After understanding the role of each port, we can now connec

, ST, and LC. Currently, the common electrical interfaces are RJ45, which are used to connect to twisted pair wires and interfaces connected to coaxial cables. However, these interfaces are rarely used. Fc nic: it is also called an optical fiber Nic. Its learning name is Fiber Channel HBA. The transmission protocol is an optical fiber channel protocol, which is generally connected to an optical fiber channel switch through an optical fiber cable. Inte

A Network Transformer will be added in the middle when the Ethernet device is connected to RJ45 through the phy. What is the role of this transformer? Theoretically, transformer can be directly connected to RJ45 without being connected. However, the transmission distance is very limited, and when connected to different levels of Network Ports, it will also affect. In addition, the external interference to t

A wireless router is a network device that can be connected to a LAN or a WAN and has both the broadband routing and Wireless AP functions. There are two types of wireless routers. One is an ordinary dual-port wireless router without an exchange module. One RJ45 port is a WAN port used to connect to broadband, and the other
