. The difference is that the LRP configuration method is relatively primitive, each step requires a command line or a configuration file to be modified. freesco provides an interactive menu wizard configuration program, making it easier to operate.Currently, the latest version of freesco is 0.3.2, based on the Linux 2.0.38 kernel. Available on the software Homepage.System RequirementsThe computer used as a router needs to have a CPU of more than 386, 8 MB of memory, a soft drive, a NIC connected

has a built-in modem for the ESS, will that be the problem? So the author in the resource manager carefully checked the built-in modem, did not find a yellow exclamation mark, However, when the author chose to "View the device by connection", and then click "Computer" to show all IRQ interrupts, but found that the original ESS built-in modem and USB devices are

and local switches and optical network units in the residential area (ONU). The residential area uses 5 types of twisted pair wires for Integrated Wiring, and the user's Internet access speed can reach 1-10 Mbps. Unlike the dedicated bandwidth solution of FTTH, FTTx + LAN is shared by multiple users or families, it is difficult to guarantee its bandwidth or network speed. Ii. FTTH access technical standards Currently, the ADSL2 + and FTTH with dedicated bandwidth have become the mainstream tren

noted that it is different from the common "FTTx + LAN (optical fiber + LAN)" Broadband Access solution. FTTx + LAN is a Broadband Router Access solution that uses optical fiber + 5 twisted pair wires to achieve "Mbps to residential area or Building, 1-10 Mbps to home"-vswitches in the residential area and local switches and Optical Networks unit (ONU) connected, the residential area uses 5 types of twisted pair wires for Integrated Wiring, and the user's Internet access speed can reach 1-10 Mb

service that combines voice, data, and television. This will be the "killer application" of future household businesses ". The main disadvantage of EPON/GEPON is its low efficiency and difficulty in supporting services other than Ethernet. The former adopts 8B/10B line encoding, resulting in 20% bandwidth loss, while APON and GPON both adopt non-return NRZ) scrambling codes as line codes, so there is no bandwidth loss. In addition, the bearer layer,

cable cables ). This optical cable is mainly used from the central data center to the user allocation box. In the project completed by rosenberger, only two types of optical cables can be used at most from the central data center to the floor distribution box. Reducing the category of optical fiber cables helps to increase the length of optical fiber cables to be used, and helps manufacturers provide fast response capability and price competitiveness. 5. Easy resizing Currently, the splitting r

applicable problem: after the light cat setup, the computer failed to dial. Solutions Computer to dial before dialing, you need to set up a light cat registration, set the method please click the Reference document . If you have already set up a light cat, follow these methods: Observe that the light on the PON device is normal, and normally the power and pon lights of the PON device are always on, and the Los Lights (red) are off. The Los lights did not

. (WEP has a basic defect that allows attackers to obtain keys by analyzing the so-called initial vector Initialization vectors .) Call data using mobile phones There are countless types of mobile phones in the current market, but most of the mobile phones with data transmission capabilities use a common communication method to communicate with the data MODEM in mobile phones or network providers. The Linux abstract Control Model (ACM) is designed to

This article includes common classic problems in broadband sharing. You can take a look at any questions about network sharing! 1. What are the benefits of shared bandwidth? Now, broadband networks have been activated in many places, and the network speed is greatly improved compared to that of the ordinary MODEM in the past, while the network bandwidth required for browsing web pages and chatting on the Internet is not high, if you just want a comput

CommEvent attribute contains the latest event or wrong numeric code, you can read the CommEvent attribute value in the program to understand the communication status. The OnComm event is closely related to the CommEvent attribute and used together. When any OnComm event or error occurs, this will change the CommEvent attribute value. In the OnComm event processing process, you can determine the CommEvent attribute value. For different attribute values to be transferred to different event proces

") for file transfer, without starting the server. The method is to use the ipxcopy command on one computer to start the receiver and use the "ipxcopy file name" command on the other computer for transmission. The file name can be a wildcard character, you can also use the/s option to specify files that include subfolders. Of course there are other methods, so I will not introduce them here. The above is the connection method of LAN. Next we will talk about the Internet method. There are two wa

We know that the use of RS-232C protocols is well-developed in some areas of electrical and mechanical, and the basics of this are also described in previous articles. So as a supplement, we next to the RS-232C protocol interface signal to a comprehensive summary. I hope this will help you. RS-232C protocol standard interface has 25 lines, 4 data lines, 11 control lines, 3 scheduled lines, 7 standby and undefined lines, commonly used only 9, they are RS-232C protocol interface signal (1) Contact

This is related to the specific device, but generally the baud rate is 9600, the data bit is 8, the stop bit is 1, the parity is 0, and the flow control is off: if (sport!= null) ... { Logger.debug ("Serial name is:" + sport.getname ()); Try ...

Failure prompt: Error 651: The modem (or other connecting device) reported an error. (Figure 1) Figure 1 The picture of the bottom right corner of the desktop when the network cable is bad What's inside the Web Failure Reason: ADSL Access: ADSL Modem physical connection is not good; There are some problems in modem parame

Security Warning: 1.35 billion of ARRIS cable modems worldwide can be remotely attacked A security vulnerability was found in the Wired modem of ARRIS SURFboard. Attackers can remotely attack about 1.35 billion of devices around the world.Security expert David Longenecker explained that a security vulnerability exists in a very popular wired modem produced by ARRIS (formerly Motorola), affecting billions of

After the ADSL installation is completed, you will be waiting for the installation personnel to come to the door for installation. You should know about the installation method. Otherwise, you will not know how to solve the problem if you change the installation method in the future or encounter some minor problems. The installation of ADSL mainly includes: 1. installation of equipment and lines; 2. Installation of software. First, let's take a look at the installation and cabling of ADSL device

In the low-end router using DISP interface to view the corresponding serial port status information, including DCD, DTR, DSR, RTS and CTS, such as five status indicators respectively mean? DCD (Data Carrier Detect-carrier detection) DTR (data Terminal ready, terminal prepared) DSR (data Set Ready), RTS (Request to send) CT S (Clear to send clean send) in these five control signals, DTR and RTS are DTE devices (data terminal equipment, which is the router in the actual application), DSR, CTS and

The file name can be a wildcard character, you can also use the/S option to specify files that include subfolders. Of course there are other methods, so I will not introduce them here. The above is the connection method of LAN. Next we will talk about the Internet method. There are two ways to access the Internet: one

1. you can directly use the ICS shared by the operating system-one machine as the host, which is used to dial up and install dual NICs (so you do not need to purchase additional hubs or switches, you only need to add one more NIC-two computers have three NICs, and make sure that machine 2 needs to access the Internet, machine 1 is the master server ).ICS (Internet Connection Sharing) is a shared Internet service built into Microsoft Windows 2000/XP. When using this service, you only need to chec
